Iczelion's Win32 Assembly Forum [http://pluto.beseen.com/boardroom/h/19390] Edited by TomCat/Abaddon (26 Apr 1999) [mailto://tomcat@szif.hu] =============================================== Subject: Starting discussion about Win32 Assembly Date: 30 Jul 1998 08:59:26 From: Arnon Thaicharoen Hi, everybody This forum is for those who're interested in assembly programming for Win32 platform. If you have any comments, info to share, or questions to ask, post them here. I love assembly language and want to see it florish under Win32. Assembly programming on Win32 platform is really easier than the old DOS platform. We have Win32 API calls which constitutes the standard library. Work is in progress to develop the Visual Assembler which is a visual development tool for assembly language programmers. Best Regards, Arnon Thaicharoen =============================================== Subject: need help Date: 5 Aug 1998 06:19:06 From: Fox Mulder Dear Arnon Thaicharoen, it's me, Fox. Now I need a banner to link your Forum on my page about Assambly language programming for Win32. May you make this one for me? Thanks! And good luck! Fox Mulder. =============================================== Subject: Visual Assembler project Date: 30 Jul 1998 12:18:54 From: Arnon Thaicharoen There's a new assembly project on the web. A group of assembly language programmer is building a visual development tool for assembly language in the same vein as other "Visual" programming language. The assumption is that assembly language is alive and well in Win32 environment but it's just neclected by the majority of programmers. Writing Win32 program in assembly is NOT really harder than other programming languages. You get smaller and faster programs. All is happy. period. Besides, writing Win32 programs in assembly makes you get close to the heart of Win32 system. You get to know it intimately. I admit that assembly language is notorious for steep learning curve. But nothing good in this world is for free. You must fight to get it! This Visual Assembler project is in alpha. But a beta will be due in this summer. It'll always be free for all to use. So please at least take a look at its homepage: http://www.fortunecity.com/skyscraper/lycos/403/ Regards, Arnon Thaicharoen =============================================== Subject: How do you handle graphics? Date: 2 Aug 1998 13:25:56 From: Arnon Thaicharoen :In Dos assembly programming, programmers often wrote directly to :video memory at A000:0000h, or B800:0000h. How can you bypass the :windows API functions and write to video memory the same way? I'm afraid programs cannot do that sort of thing in Windows. Ring-3 codes cannot directly access hardware device. Only ring-0 codes such as virtual device drivers can do that. :And can you give me code to find the resoloution/number of colors :on the system? sure! the code is below.

Date: 16 Aug 1998 07:11:16 From: mammon_ What?!? A Win32 assembly forum and no-one told me? ;) Ok, Barry kauler demonstrated how to write directly to video RAM in windows in his Windows Assembly Language Book. It's a little ugly, but it works... You can overwrite the windows screen if you obtain a selector to the video ram for the VM, which he says corresponds to the physical video ram (I haven't tested it). You can return to windows with repaintscreen()[from Undoc Win95] or int 31h, func 4002 (ax=4002)--though he supplies no source for this. The source he does supply is for DPMI direct-screen writes: ;DPMI.ASM ;This demo program is written in TASM v3.0. ;It uses the WINASMOO.INC OO-file developed in Chapter 7. ;This program makes use of DPMI & low-level Windows functions. ;This program relates to discussion in Chapter 9. ;remember that Windows funcs only preserve SI,DI,BP & DS.

END =============================================== Subject: Good Win95 assembly tutorial on the web Date: 4 Aug 1998 03:49:48 From: Arnon Thaicharoen I have stumbled upon a good site about Win95 assembly. It has many chapters of tutorial about how to program Win95 in assembly. It's the only site I know that contains tutorials. Visit it and download everything inside. The url is http://www.eskimo.com/~htak/win95asm/win95asm.htm Enjoy. =============================================== Subject: My own Win32 asm tut page is up Date: 24 Aug 1998 04:03:57 From: Iczelion My humble Win32 asm tutorial page is up. The url is http://iczelion.home.ml.org/iczelion. Please take a look. Any suggestion or comment is welcome. =============================================== Subject: My own Win32 asm tut page is up Date: 25 Aug 1998 16:52:07 From: Fox Mulder Hello, dear Iczelion! I like your tutorials very much. They are very professional. Now I am working on the russian translations. But one thing is strange: in the tutorial No 3. you wrote about CommandShow variable, but it is missing in your listing. Why? Good luck! Fox Mulder. =============================================== Subject: Thanks for notifying me. Date: 26 Aug 1998 19:09:43 From: Iczelion It's an error of my own. The first draft of the source code listings contains the variable CommandShow. But later, I decided not to use it. Thanks. =============================================== Subject: WinAsm channel on IRC Date: 16 Aug 1998 10:33:54 From: Arnon Thaicharoen There's a channel named #winasm in EFNET which is set up specifically for talking about programming Windows using assembly language. Admitted,I've not met anybody there yet, but it seems a good place to check out. =============================================== Subject: WinAsm channel on IRC Date: 17 Aug 1998 03:10:29 From: Iczelion :#WinAsm is dead for quite a time, only one bot there. :Though, there's #Win32Asm which is alive and kickin' :) Thanks. It's truly alive! Nice to meet all the folks there. I'll talk with you again, and again and again..... :) =============================================== Subject: DirectDraw Through Assembler Date: 20 Aug 1998 01:31:48 From: DarkFyre Does anybody kow how I can implement DirectDraw through assembler? Most/all of the code supplied with the SDK is in C, and it's messy and annoying to compile these and try and get TLINK to accept Visual C++'s .OBJ files in the final project. Any pointers? DarkFyre =============================================== Subject: DirectDraw Through Assembler Date: 20 Aug 1998 08:05:30 From: Iczelion Never program DirectDraw with assembler. But if you have the SDK and the code in C, you can write equivalent code in asm. Check out Henry's page at http://www.eskimo.com/~htak/win95asm/win95asm.htm for win95 asm programming tutorial and download win32asm toolkit from http://www.fortunecity.com/skyscraper/lycos/403/ Good luck, Iczelion =============================================== Subject: Calling conventions in win32asm Date: 22 Aug 1998 19:03:16 From: Net Walker! Hi all, I would like to suggest you, Win32 Assembly coders, use function prototypes in order to make easier to write code in assembly. If you have Tasm 5.0 you can avoid the boring way of pushing parameters to stack in reverse order...then call the function name (after making an EXTRN declaration at the beggining of the source file). What I mean is, instead of using: EXTRN MessageBoxA : PROC . . . push 0 push offset MyTitle push offset MyMessage push hWnd call MessageBoxA you can create a prototype for MessageBox: PROCDESC WINAPI MessageBoxA :DWORD, :DWORD, :DWORD, :DWORD then, when you need to use MessageBox, you just type: call MessageBoxA, hWnd, offset MyMessage, offset MyTitle, 0 Its very similar to C coding, isnt it? Obviously, a productive way for using such an approach would be creating a .inc file with all Win32 API function prototypes. There is already a include file done by Barry Kauler and modified (a little) by me. It doesnt have yet all the function prototypes, but I'll be working on it from now on - in order to use it in Visual Assembler. If you use MASM, you can have such file already done - look for Walk32 example. Another thing I'd like to suggest you regards using resource scripts in order to create the whole GUI (even the main windows). You can found an example about such things (prototypes and resource script) in my tiny debugger Nwdebugger 0.3 - you can found it on Lord Caligo, Stone, Sudden Discharce and some other sites. I'm just returning from a long trip and after installing Mirc (i lost my HD 2 months ago) I will look for you guys at #win32asm. Have a nice day... ..now its time to have a look at Visual Assembler ptoject :) =============================================== Subject: Function prototype in MASM Date: 22 Aug 1998 23:21:56 From: Iczelion In MASM, you implement function prototype like this: MessageBoxA PROTO STDCALL,:DWORD,DWORD,:DWORD,DWORD then, when you need to use MessageBox, you just type: call MessageBoxA, hWnd, ADDR MyMessage, ADDR MyTitle,MB_OK :call MessageBoxA, hWnd, offset MyMessage, offset MyTitle, 0 =============================================== Subject: Function prototype in MASM Date: 22 Aug 1998 23:54:29 From: Iczelion In MASM, funcion prototype is defined like this: MessageBoxA PROTO STDCALL, :DWORD,:DWORD,:DWORD,:DWORD then, when you need to use MessageBox, you just type: invoke MessageBoxA, hWnd, addr MyMessage, addr MyTitle, MB_OK You can use offset instead of addr. :Another thing I'd like to suggest you regards using resource :scripts in order to create the whole GUI (even the main windows). : You can found an example about such things (prototypes and :resource script) in my tiny debugger Nwdebugger 0.3 - you can :found it on Lord Caligo, Stone, Sudden Discharce and some other :sites. I've examine it. A good work of using resource script. :) :I'm just returning from a long trip and after installing Mirc (i :lost my HD 2 months ago) I will look for you guys at #win32asm. We at #win32asm are looking forward to you. =============================================== Subject: MessageBox fonts and size Date: 30 Aug 1998 20:18:19 From: TomServo :Is it possible to control the font and the size of the MessageBox :function? If no, is there other API's which is able to do so? :Thx. The font and size, etc of a messagebox is determined by the system defaults. IE, they are the same as used on all window title bars, etc. I believe it is kept in the registry, but i'd have to dig up exactly where and I am not at my "developer" machine this weekend. Keep in mind changing them for your dialog box changes them for everything re-painted in any app until you change it back. If you really desire such customality, perhaps it is best to use a dialog box. =============================================== Subject: MASM or TASM? Date: 30 Aug 1998 20:23:01 From: TomServo I'm just beginning program development in ASM for the '86 platform. My intent is to be able to turn out a few VxD's and the occasional light tight Windows app. My main question before I get too deep into this is which should be my tool of choice, MASM or TASM? Is one better then the other (ie, I have read TASM can be co-erced to do OOP easily), or is this mostly a matter of taste? My only comment is I have all the MS .inc and .h I would need, getting the Borland equivalents would be another project. Thanks. (And hello to you all on the forum) =============================================== Subject: MASM or TASM? Date: 31 Aug 1998 06:17:36 From: Iczelion Well, I don't want to start a debate about TASM VS MASM. If you read Barry Kauler's book, "Windows Assembly Language and Systems programming", you can look at the preamble of the chapter "ring-3 code". In summary, Kauler suggests that you use MASM. TASM 5.0 follows the steps of MASM so you can convert MASM source code into TASM equivalent with reasonable ease. However, he also points out one problem: Passing parameter to a function in TASM may be problematic if that parameter is a local variable since TASM uses OFFSET directive to assign the address at assemble time and the address of local variable is not known until runtime. MASM use ADDR which is fine under the circumstance. If you want to program VxDs, I think you should consider MASM. =============================================== Subject: MASM or TASM? Date: 11 Sep 1998 14:31:45 From: david11372 I, too, have read Barry Kauler's book and although he makes an attempt to discuss the use of both MASM and TASM, I think you will find any sample assembly programs on the Internet all use MASM. According to Mr. Kauler, Borland tried to play catchup with TASM 5.0, yet there are some subtle differences that will drive you up the wall. I started out with Borland TASM in engineering school and have stayed with their products. It was perfect for a digital control system design I did, however, now that I am trying to recode the pgm for Windows 95 use, I wish I had MASM. Life would be much simpler. Dave =============================================== Subject: Assembling VxD's and coff option trouble Date: 31 Aug 1998 03:40:06 From: TomServo I'm new to this particular stuff. I'm attempting to just assemble some sample VxD's, but I always generate similar error messages to this. set ML=-coff -DBLD_COFF -DIS_32 -nologo -W3 -Zd -c -Cx -DMASM6 -DINITLOG -DDEBLEVEL=1 -DDEBUG -Fl ml -Fovxdbody.obj vxdbody.asm Assembling: vxdbody.asm vmm.inc(495): error A2210: 16 bit segments not allowed with /coff option vmm.inc(499): error A2210: 16 bit segments not allowed with /coff option NMAKE : fatal error U1077: 'C:\DevStudio\VC\BIN\ml.exe' : return code '0x1' Stop. Error executing NMAKE. I believe the coff option is a file format needed for the link.exe to use, but apparently it isn't good for mixing 16 and 32 bit code. Any suggestions or hints? Thanks in advance. =============================================== Subject: Assembling VxD's and coff option tro Date: 31 Aug 1998 06:02:02 From: Iczelion COFF is the file format that Win32 borrows from Unix. I believe that VxD uses LX file format. /coff is not necessary for link. TASM generates OMF files exclusively. OMF is the old Intel file format that 's used before Windows 95 came about. I think MASM can generate OMF files as well but haven't try yet. =============================================== Subject: Assembling VxD's and coff option tro Date: 2 Sep 1998 01:04:38 From: TomServo Thanks, dropping the coff attributes from the .mak file and it compiles and links just fine. (Well, does make half a hundred warnings, but nothing too serious looking). I think the file will even work (comparing the dis-asm with the origional) =============================================== Subject: Assembling VxD's and coff option tro Date: 11 Sep 1998 04:03:18 From: TomServo A final item: If I use ml.exe from the win98ddk (free at microsoft.com), the coff options work just fine. I've read this version of ml was custom taylored for VxD's. =============================================== Subject: Process Information Date: 11 Sep 1998 19:47:05 From: Andoni Hello! Anyone know how I can know what are the process that are running, I've heard that I have to use Process32First & Process32Next. =============================================== Subject: Julian date conversion Date: 11 Sep 1998 14:37:08 From: david11372 Can anyone give me advice on what WIN32API function call to use that will put the current date in the tm structure. I have also noted that is a tructure called SYSTEMTIME, however, the tm structure has an additional parameter called tm_dyear which I need for setting up the Julian date. Any help would be greatly appreciated. Dave =============================================== Subject: Julian date conversion Date: 12 Sep 1998 05:37:35 From: TomServo I strongly suggest you go to Microsoft's MSDN site and sign up, there is much info worth finding there. I got this from the MSDN CD that came with MSVC. Well worth the $60-70 the academic verison of version 5 pro cost me, you can even use the Developer Studio environment for asm work. The GetLocalTime function retrieves the current local date and time. VOID GetLocalTime( LPSYSTEMTIME lpSystemTime // address of system time structure ); Parameters lpSystemTime Points to a SYSTEMTIME structure to receive the current local date and time. Return Values This function does not return a value. (This is in C syntax, of course) =============================================== Subject: Writing to console Date: 13 Sep 1998 22:57:36 From: Ghiribizzo Is it possible to write to the console of the dos prompt. i.e. C:\>myasmprog Text out in this console here. Program ends. C:\> i.e. how does one get the handle to the current console? =============================================== Subject: Writing to console Date: 14 Sep 1998 07:17:45 From: mammon_ :hmm. this forum doesn't seem to cope well with arranging text. To :clarify: is it possible to write to the same console the app is :run from (i.e. not create a new console). I have found that writing to the stdout works fine. Are you trying to mix console apps with a GUI, i.e. GUI apps that are launched from the console and respond back to it? That seems kind of weird.... =============================================== Subject: Writing to console Date: 15 Sep 1998 07:11:27 From: mammon_ :If I'm reading you right, you wish to run a program in a dos box :and have your text appear there? If so, all the DOS INT 21H :functions are still there for use. That's what would have been my 'Hello, World' app ;) Good ole int 21h func 09h You can always play with the video modesusing int 10h as well, but on reflection it seems that you may be trying to use the Win32 API functions along with dos interrupts. As long as you keep the windows.inc you should be Ok, no need to get the DOS console handle, though if you want to be true to the MS way you should use DPMI. Of course, you may be trying to use this: WriteConsole( hConsoleOutput, *lpvBuffer, cchToWrite, lpcchWritten, lpvReserved); which admittedly I have never tried in assembly language. I assume that GetStdHandle( STD_OUTPUT_HANDLE ); would work even in asm, but if I can assume you've tried that then I would recommend sticking to the Int21h functions...I found that as long as I do not use a wndclass-based program they work OK. _m =============================================== Subject: Writing to console Date: 15 Sep 1998 19:41:10 From: Ghiribizzo I'm using the GetStdHandle and WriteConsole functions. They're not working, but I think they should as I've seen similar code elsewhere. I'll check my code. Also, my first program was basically a push 0, call exitprocess. However, it crashes. But when I put in the GetModuleHandle function (usual 3 lines, push 0, call, store in whatever) it works. Is this normal? I'm using TASM at the moment. =============================================== Subject: Writing to console Date: 22 Sep 1998 08:38:41 From: razzi :Can you email me a simple Hello world program? I'm having trouble :getting the console handle via getstdhandle. Hi ghiri, There are API's that you can use to write to and read from the console. But i see you already figured that out :--) The reason that "they dont work" is perhaps you didnt link your program to be a console app. I think tlink32 makes GUI apps by default. (Actually the only difference between a GUI app and a console app is the value of one flag in the PE header) If you want sources, i think stone has some on his page. I got some too, let me know if you are interested. hope this helps, razzi@usa.net =============================================== Subject: windows.inc Date: 14 Sep 1998 07:21:21 From: mammon_ :Is there a full windows.inc file zipped up somewhere on the net? :I've got a few bits and bobs? If not, would somebody mind :concatenating the .h files and u/l them somewhere on the net? There is one inside the disk for Kauler's book (my site and others) for TASM; there is one inside Walk32 (my site and others) for MASM, and there is one inside Gij's Nasm-Win32 toolkit for Nasm (greythorne's site). If you need any of these I can email them to you. For the record, none of them is *thorough*, although I think Gij made the best attempt to be thorough--the others were more of a "what-is-most-commonly-used" functions list. _m =============================================== Subject: windows.inc Date: 14 Sep 1998 09:12:47 From: g I'm working on one for NASM, will be releasing a win32_lean_and_mean (ha! is that a joke or what?) version when I've finished them. So far I've done: windows.h imm.h mcx.h ole2.h winbase.h (now in lots of little files) wincon.h windef.h winnetwk.h winreg.h winresrc.h winsvc.h wintypes.h Have yet to do: winnls.h wingdi.h winuser.h winnt.h winerror.h lots of includes for ole2 All the externs will have macros to go with them so they can be called just like a HLL without having to worry about writing a load of pushes every time (what a pain). Doing these by hand takes a while.....but it'll be worth it for nice small apps. I intend to also release some non-trivial demos to go with it (ie not just a hello world app). Probably a CD-player app (simple, yet demonstrates many Win32 principles). I will eventually go the whole hog and try for DirectX as well...then we have proper speed, DirectX w/asm. Eat my dirt! l8r, g =============================================== Subject: windows.inc Date: 15 Sep 1998 06:59:39 From: mammon_ :Thanks, I have all of those.

I have posted it on my homepage at address, http://www.pbq.com.au/home/hutch/download/l2i.zip It produces MASM prototypes by default but has a text search & replace which will convert PROTO to PROCDESC for TASM in MASM mode.

The console mode version uses produces either MASM or TASM syntax from command line options and will run in batch mode. Testing so far indicates that this version completely eliminates duplicate prototypes and the include files work in MASM with no editing. http://www.pbq.com.au/home/hutch/download/l2inc.exe I will email this version to Iczelion for posting on his site as this may be more convenient in terms of bandwidth. I now have a working "windows.inc" file that has all the equates and structures but it may still be a bit rough around the edges. It works in MASM with the include files generated by the l2inc.exe program so if anyone needs it, email me and I will post it on my home page. hutch =============================================== Subject: LZEXPAND.DLL Date: 15 Sep 1998 23:33:48 From: Ghiribizzo The API ref mentions that there is a compressor called compress.exe which will compress to the format that lzexpand can understand.

In older versions of MASM, you have to specify the program entry point with a linker switch, /ENTRY: So, in your case, you may have to link with these switches: Link /SUBSYSTEM:WINDOWS /ENTRY:start /LIBPATH:c:\masm\lib win.obj :I am using Macro Assembler Version 6.11 and Incremental Linker :Version 5.12.8078. I'm sure the code itself is fine. I changed :the makefile paths to my own, did I miss something? You should patch MASM to v 6.13. Download ml613.exe from my page and patch your own copy of MASM.

Is :this the way to do things in win32? I suspect not. You can use the same approach under Win32 but it's not recommended. Under Win32, you should use memory-mapped files instead. When you use a memory-mapped file, you can safely assume that the whole file is in memory. You can read from and write to any location in the file using a pointer much like you do with a memory region. You don't have to worry about allocating a memory block. In fact, the PE loader uses this method to load PE executables into memory. =============================================== Subject: Large File Buffers Date: 25 Sep 1998 00:22:25 From: Ghiribizzo Thanks for the info.

Jubee =============================================== Subject: drawing Date: 25 Sep 1998 13:19:42 From: Ghiribizzo I've been playing around with a few things connected with the DC api functions. I've been trying to vary the pen color but it seems to be either black or white. I think I've locked the bitmap into black and white mode, but I'm not sure. Also, if you try moving the window about, the background fuzz changes. Any idea where this fuzz comes from? Files are available from: http://www.chocbar.demon.co.uk/ghiribizzo/sp.zip =============================================== Subject: drawing Date: 25 Sep 1998 16:25:00 From: TomServo I took a look at your code cause I'd like to play with more API painting myself, I've read a few resources on the subject but never gotten around to writing my "learning" code myself. Unfortunately, we speak different assemblers, you TASM, me MASM, and I cannot cross that bridge yet. But I get the idea of your code. It looks to me likw you use CreateCompatibleBitmap to create your working area and BitBlt to get it out to the world. This is fine. The "noise" you see is uninitionalized memory, the actual leftover RAM data where the bitmap was created. This is easiest to fix: Before you draw your Micky Mouse elipses draw a rectangle with a black brush to fill the bitmap black. Now you have colors, which brings us to paletts, where I cannot lead you. Good luck. =============================================== Subject: drawing Date: 25 Sep 1998 23:13:59 From: Ghiribizzo I must be going mad. I forgot that I put the drawing routines into the message loop! BTW, I really ought to have put it in WM_PAINT rather than WM_MOVE, but I get lazy when in the testing phase. =============================================== Subject: drawing Date: 25 Sep 1998 20:44:04 From: Ghiribizzo :The "noise" you see is :uninitionalized memory, the actual leftover RAM data where the :bitmap was created. This is easiest to fix: Before you draw your :Micky Mouse elipses draw a rectangle with a black brush to fill :the bitmap black. Hmm. I thought about uninitialised ram. The thing that confused me is: shouldn't the noise be the same when you move the window about? =============================================== Subject: drawing Date: 26 Sep 1998 11:14:12 From: TomServo No, really, the noise is uninitialized ram. Try running your app a few times in sucession. When I did this, I could see the Micky Mouse from the previous run scroll thru my new window as I draged it around the screen. When you CreateCompatableBitmap, the bitmap itself chosen is a default 1x1 black and white bitmap. That's hardly enough area to cover your window, hence uninitialized area. =============================================== Subject: String transfer to dialog box Date: 26 Sep 1998 02:34:05 From: mammon_ :Is there a way to place a string created in your ASM file into a :dialog box prior to its display, yet not use the rectangular :EDITEXT box to dsplay it? If so, what changes need to be made in :the .RC file and which WIN32API function needs to be used? Thanx You have to use the Static Text control. In Borland this is CONTROL "YourText", -1, "BorStatic" in Symantec it is LTEXT "YourText", IDC_STATIC by default...so it is probably resource-compiler specific. =============================================== Subject: String transfer to dialog box Date: 28 Sep 1998 09:39:59 From: hutch If you want to set the text of an edit control in a dialog box from you program code, trap the WM_INITDIALOG msg in the dialog message proc and use SendMessage to send a WM_SETTEXT message to the edit control. =============================================== Subject: equates Date: 26 Sep 1998 11:22:31 From: TomServo :Hello.

I've used a similar method as in my last post to load a bitmap. I have a few questions to ask the win32asm gurus: 1. What is the best way to keep the bitmap 'updated' e.g. after window move/resizes etc. 2. Is it obvious where the program may be leaking GDI resources? I ran the program about 40 times and saw my GDI resources dropping. I'll probably run bounds checker on it later as I think that detects such things. File can be found at: http://www.chocbar.demon.co.uk/ghiribizzo/mc.zip =============================================== Subject: bitmap fun Date: 27 Sep 1998 21:37:34 From: TomServo :2. Is it obvious where the program may be leaking GDI resources? Oh yeah, in your orgional post you leaked resources a plenty. ;-) ; the following is psudo-asm code to track API GDI calls: ; see sp.asm wmmove: newhwnd = 0 call GetDC (newhwnd) ; this is the DC for the ; entire screen (since ; newhwnd = 0) mov WinDC,eax call CreateCompatibleDC(WinDC); a private area to work mov MemDC,eax call CreateCompatibleBitmap(MemDC) mov hBitmap,eax call SelectObject(hBitmap) mov hOldBitmap,eax call CreatePen mov hPen, eax call SelectObject(hPen) mov hOldBrush,eax call Ellipse ; do some drawing with the pen call Ellipse call Ellipse call BitBlt ; paint the drawing on the screen ; this clean-up was omitted in orgional code ; we have to delete the GDI resources we created SelectObject (hOldPen) ; restore the orgional pen to the ; DC (it is a bad thing to delete ; a selected resource) DeleteObject (hPen) ; delete our new pen SelectObject (hOldBitmap) ; restore the orgional bitmap ; to the DC DeleteObject (hBitmap) ; delete our new bitmap DeleteDC (MemDC) ; delete the DC we created ReleaseDC (WinDC) ; releace the DC we borrowed ret You might want to keep the orgional DC and bitmap you created around and just BLT it over again for re-paints from window moves or such. =============================================== Subject: bitmap fun Date: 28 Sep 1998 09:58:35 From: hutch The bitmap stays updated if it is drawn from WM_PAINT message. That is the normal place to draw a "persistent" bitmap from. You will get memory leaks if you do not use the APIs SelectObject and DeleteObject correctly. I will have a look around and see if I can find it in C or similar. I have got it floating around in everything except ASM. You usually use BitBlt() for placing the bitmap or StretchBlt() to change its size ands place it. hutch =============================================== Subject: bitmap fun Date: 28 Sep 1998 10:28:48 From: hutch Ghiribizzo, I found some ASM that shows how to use SelectObject() and DeleteObject(.

I've managed to implement one tied to an edit box but there seems to be a problem. In the API prototype, it states the min/max values are INTS which would be 32 bits in a win32 system, I assume. However, in the UDM_GETRANGE structure, it states that it is only 16 bits. To confuse matters, having experimented a little, the min/max values don't seem to have any sense to them at all!! It isn't too bad. The control doesn't specify the dword for the current position (which I need to do for my particular application) so I will probably write my own custom control for it. However, I've let you have this to have a play around with. Another thing I was playing around with in this was making the whole window 'draggable' you'll see what I mean.

Yes, I use DirectX a fair bit. I'm in the process of tidying some demos up for presentation and will be putting them on a friend's web site. Mail me and I'll let you know when they're up. Mike =============================================== Subject: Direct X Date: 14 Oct 1998 22:21:24 From: Mike Bibby I've got a couple of the demos ready and I think I've emailed them to everyone who contacted me. If I've missed you, sorry. They'll be on a site soon. In the meantime email me and I'll send you them. They're TASM and MASM. The one I'm sending out is just a toy but it will get you up and running, showing how to create DirectDraw objects, how to call their methods, and how to perform a primitive animation... Cheers, Mike =============================================== Subject: Compiler for motorola 6800?? Date: 30 Sep 1998 04:36:00 From: John Craig Hello, I've signed up for an assembly course here at the university of minnesota. I know nothing about assembly at this point, but am eager to get started. The instructor requires the class to use assembler for motorola 6800. I'm not even sure what a motorola 6800 is, but I'm guessing that a desktop PC doesn't qualify. So, does anyone know of a way that I can write and test programs in Windows95 and then compile them for motoroloa 6800? --john craig crai0046@tc.umn.edu ps Please forward a copy of any replies to me via e-mail. thanks. =============================================== Subject: Compiler for motorola 6800?? Date: 30 Sep 1998 10:07:53 From: mammon_ Motorola processors are used in a number of machiens, but mostly Macs and Amigas. I came across a ton of motorola stuff on this Amiga page: http://home.sol.no/~tj1040/assem/ you should be able to find some emulators there =============================================== Subject: Compiler for motorola 6800?? Date: 14 Oct 1998 00:59:36 From: ren_ he, it seems that this particular assembly class is a bit outdated ,whereas the 68xx family(not to be mixed with the 680x0 family, mammon_, which is used in the Mac,Amiga,ST,QL,etc hardware :)isn't that bad for starting assembly. superior to the MOS65xx processors (although i only started realising that when thinking about a fast emulation of an 6809 myself)it's a good solid ground on which you can easily build up some base knowledge, which than can be ported to newer processors. But one last question, why are the guys teaching such a thing ??? Even in my very opinion it's only interesting because of retrospective reasons. No one (except nerds, arcade lovers (such as i am), and weird peoples) is interested in such a microprocessor, nowadays. He better should force his profs to teach him some MIPS, ARM, alpha or whatsoever assembly language (and i really don't recommend the x86 family as a primer !!!!) Just my 2 cents :).

I have my combobox built. I have an example from a C program, but I'm having a hard time trying to convert it. Years ago I was a wiz bang 370 assembler programer on the mainframes, but what a difference with the PC. Any help would be appreciated. Ewayne =============================================== Subject: Loading a combobox Date: 30 Sep 1998 13:46:37 From: hutch Ewayne, You will have to get that big pig M$ help file win32.hlp as it has all of the messages in it. If you look up the index with CB_ you will get a heap of messages to do various things with combo boxes. You can use the, CB_ADDSTRING message to add zero terminated strings to a combo box which you send with the SendMessage() function. Hope it works OK for you. hutch =============================================== Subject: Loading a combobox Date: 30 Sep 1998 15:54:58 From: Mike Bibby I've got a very simple, standalone example program that uses a combo box to let you choose between two dummy routines to run. Part of a series of exemplar programs for Windows 95, its written for TASM5, but should be really easy to adapt. I wasn't going to release it this early, but mail me if you want a "beta copy". Mike =============================================== Subject: Combobox Selection Field Date: 2 Oct 1998 00:58:21 From: Ewayne First I want to thank all who has helped me with my program. I want to save the selected item in the selection field of my combobox to a string, example an executable program to call later. I'm using CB_GETITEMDATA and I think the address of the selected item is returned in lParam, but I guess I don't know how to extract it. I can get the index of the selected item using the eax reg with CB_GETCURSEL and I could write a routine to build a string with the index, but there must be a better way. THANKS AGAIN Ewayne =============================================== Subject: Combobox Selection Field Date: 2 Oct 1998 09:46:19 From: hutch Ewayne, you need to subclass the combo box to process the messages like mouse clicks etc.. This is done by writing a message style proc something like a WndProc message handler. What I have pasted in below is the message handling proc for the listbox code that I posted before. ListBoxProc proc hCtl :DWORD, uMsg :DWORD, wParam :DWORD, lParam :DWORD LOCAL IndexItem :DWORD LOCAL Buffer[32] :BYTE .if uMsg == WM_LBUTTONDBLCLK jmp DoIt .elseif uMsg == WM_CHAR .if wParam == 13 jmp DoIt .endif .endif jmp EndDo DoIt: invoke SendMessage,hCtl,LB_GETCURSEL,0,0 mov IndexItem, eax invoke SendMessage,hCtl,LB_GETTEXT,IndexItem,ADDR Buffer szText CurSel,"You selected" invoke MessageBox,hWnd,ADDR Buffer,ADDR CurSel,MB_OK EndDo: invoke CallWindowProc,lpLstBox1,hCtl,uMsg,wParam,lParam ret ListBoxProc endp The following code is the proc call for the listbox, the SendMessage call stuffs it full of file names and importantly, the SetWindowLong() call sets up the address of the message handling proc for the combo box. Make sure you put the handles hList1 for the list box & lpLstBox1 for the proc address in either your .data or .data? sections. Once you have this subclass up and going, you can pick list items out, add them in and do whatever you like. Just note that the list box and combo box messages & styles are different and you have to use the right ones. invoke ListBox,20,90,150,200,hWnd,600 mov hList1, eax szText Patn,"*.*" invoke SendMessage,hList1,LB_DIR,DDL_ARCHIVE,ADDR Patn invoke SetWindowLong,hList1,GWL_WNDPROC,ListBoxProc mov lpLstBox1, eax hutch =============================================== Subject: Combobox Selection Field Date: 2 Oct 1998 14:30:45 From: Ewayne Hutch, Everything in your example above is clear except 'invoke ListBox', should it be 'invoke ListBoxProc'? If not where is it pointing to? When should it be run, right after I create the listbox? Thanks Ewayne =============================================== Subject: Combobox Selection Field Date: 2 Oct 1998 16:26:54 From: Mike Bibby Ewayne, I'm not sure what that invoke ListBox is... Possibly it's a wrapper for a call to CreateWindow(Ex). Here's a simple demo that creates the sort of ListBox implied by the invoke.

I think Hutch has me pointed in the right direction by sub classing the boxes, but I'm confused by his call to listbox. If it's a call to a create listbox proc, it doesn't look like the parameters match. Thanks Ewayne =============================================== Subject: Combobox Selection Field Date: 2 Oct 1998 17:42:12 From: Mike Bibby As I said, I think it's some kind of wrapper to CreateWindowEx, but we'll have to wait until he posts us the answer. I'm a bit puzzled as to exactly what you need, but to copy the currently selected item in a list box to a string use something like: ; find out what's selected call SendDlgItemMessageA, dhwnd, IDC_COMBO1, CB_GETCURSEL, 0, 0 ; ;put its string in szBuffer call SendDlgItemMessageA, dhwnd, IDC_COMBO1, CB_GETLBTEXT, eax, offset szBuffer I'll post you a zip of something that uses these ideas to run files.

Being a new user any Tips on setup and updating? I aware of v611d,v612 and v613 updates. I have asked this question due to time restraints rather than indolence. Any information at any level would be greatly appreciated. cheers Rundus :) =============================================== Subject: MASM v611 Date: 2 Oct 1998 11:54:20 From: Iczelion Good. A new MASM member :-) However you should know that link.exe that comes with masm 6.11 cannot be used to generate a dos program. If you want to assemble a DOS program, you should get MASM 6.0's link.exe. You should download MASM 6.13 patch. It can patch MASM 6.11x (except 6.11c) to patch level 6.13. You can download it from: ftp://ftp.microsoft.com/softlib/mslfiles/ml613.exe Run ml613.exe in your MASM directory, it will explode into several files. Run patch.exe and your MASM is instantly updated to 6.13. Good luck, Iczelion =============================================== Subject: MASM v611 Date: 2 Oct 1998 09:55:39 From: hutch Guys, If you are having problems with versions of ML.EXE, download the 6.11d version from Iczelion that came from the win89DDK, get the version of link that came with it and then run the 6.13 patch that you can also find on Iczelion's site. You also need CVTRES.EXE from either the DDK or VC5 to convert a normal RES file into an object module for linking with your program code. This will give you the latest versions of everything which will assemble and link program code and resources into win32 EXE programs. The rest is Rock 'n Roll missile ware. hutch =============================================== Subject: MASM v611 Date: 2 Oct 1998 04:09:05 From: TomServo Iczelion has been kind enough to post the 6.11-6.13 updates at http://203.148.211.201/iczelion/ (I didn't get em right my first try, need to get back to it. The ml.err file is screwed). One thought is if you have Visual C is to use Visual Studio to work on asm programs. I'm already used to and happen to like the enviroment, as it can handle multiple files and resources too. (Yeah, the resource files are the same for C as asm). I'm still getting the makefiles down for this, mostly problems with getting rc and makebsc to work from a build command (I can run em from a command prompt). =============================================== Subject: MASM v611 Date: 2 Oct 1998 05:29:05 From: Ewayne Tom I'm running ML 6.13 and the ML.ERR is dated 10-29-97 9,622 bytes and I haven't had any problems yet. If it is newer then yours and if would like a copy I'll E-MAIL to you Ewayne =============================================== Subject: MASM v611 Date: 4 Oct 1998 06:29:14 From: TomServo Ewayne, Thanks for your offer.

Finding the length of the string: --> lstrlen Compare two strings: --> lstrcmp, lstrcmpi Copy a string to other location: --> lstrcpy Concatenate two strings: --> lstrcat They're clean and easy to use. It'll make your program smaller and easier to maintain. Regards, Iczelion =============================================== Subject: String support API functions Date: 6 Oct 1998 09:41:35 From: MIke Bibby Definitely! They're what I use. You pre-empted me: I was going to use them in the next iteration of this thread. The primitive stuff was because I thought the "garbage" he was getting might have been due to a confusion between pointers and actual data and this would have illustrated the difference, plus a few new instructions. Cheers, Mike =============================================== Subject: windows 95 or 98 sdk Date: 6 Oct 1998 14:05:28 From: Brut where can I find the sdk for windows 95 or 98. I just purchased the book Windows Assembly Language and Systems Programming and it makes reference to the windows sdk. BTW this is a great book on assembly language programming for windows. If interested you can find it at amazon.com, do a search for assembly, ISBN 0-87930-474-X =============================================== Subject: windows 95 or 98 sdk Date: 6 Oct 1998 23:40:51 From: hutch just do a search in AltaVista for "platformsdk" and pick the site where you will get the best download time. Its about 50 meg or so but you get the full set of import libraries, later binaries, ML.EXE, LINK.EXE etc.. hutch =============================================== Subject: windows 95 or 98 sdk Date: 7 Oct 1998 14:37:04 From: Brut Thanks TomServo, I downloaded and installed it. It would be nice to have the documentation for it though. : Microsoft itself is now downloading the Win98 DDK, which has :all the .inc files of the SDK you could ever want. You need to be :registered for MSDN, but that's free. Yepper, they are finally :giving this away (it used to cost $500 to get em). Be careful, it :has a special version of link and ml (they are modified for :device driver use). : :http://msdn.microsoft.com/ =============================================== Subject: windows 95 or 98 sdk Date: 7 Oct 1998 03:24:32 From: hutch Brut, I slightly messed up the files, you will get the libraries and tools from the platformsdk. For the later versions of ML.EXE, LINK.EXE, CVTRES etc... you will need to download the WIN98DDK.EXE from the same source. Go back to msdownload and look for win98. I think Iczelion has this stuff on his ASM site. You will need to stuff the 6.13 upgrade through ML.EXE to bring it up from 6.11d to 6.13.7299 and I know that Iczelion has that upgrade on his ASM site. If you want to download the DDK make a few cups of coffee as it is a 19.5 meg download. hutch =============================================== Subject: windows 95 or 98 sdk Date: 8 Oct 1998 01:17:13 From: hutch Brut, You will need the platformsdk libraries as the DDK ones are not complete and sad to say, you will find the header files are very disappointing, if you check the WNDCLASSEX structures for example you will find that they differ in data size from the standard C, C++ that work correctly with the full DWORD data types. MASM is still not strong on the ground in terms of documentation. I use the PWB to access the alang.hlp help file for MASM specific syntax, PROTO, invoke, .if, etc... The data on mnemonics is best got from Intel as it is the most up to date and very comprehensive if you can suffer PDF format. Depending on your bandwidth access, an Altavista search on platformsdk will give youy a number of sites internationally to get the platformsdk files from.

I'm not sure if it's included in :Win98 DDK. The latest version I have seen is in the platformsdk. for what it is worth, any version over the last few years seems to work OK so there may be no great gain in chasing the latest. One thing, it is a good idea to run it with the /v option so that you can see if different resources have compiled properly. hutch =============================================== Subject: ReadFile Date: 9 Oct 1998 03:43:19 From: Ewayne In my learning program I'm reading text files and displaying them to the screen. I'm quite proud that it works fairly well, but I can't belive the amount of code it took to do such a simple task. Some questions. 1. When the file size is greater then the param. (number of bytes to read) it reads in a double buffer, is that normal or does it always try to double buffer? I had a hard time getting the right record to process when I read in the next block of records. 2. If the input file had tab stops the output display did not show any blank spaces where the tab stops were, is there a way to override that? 3. Is there a simple way to change the display font? I would like to change it to fixed width font, it would make controlling the word wrap more accurate then using tm.tmAveCharWidth. 4. I put a vertical scroll bar on my my main window, it's visible, but not functional??? 5. Last but not least, there has to be a better way of doing a readem and writem. I hate to think of using the same amount of code to write the display to disk. I've been reading about file mapping in memory, is that what I should be using? If so how do I get started, are there any samples available? =============================================== Subject: ReadFile Date: 9 Oct 1998 11:00:33 From: Iczelion :1.

You have to create a logical font first by calling CreateFont or CreateFontIndirect and select the newly created font into the device context. :4.

I was using TextOut to write a buffer to my screen and I could control the x, y coordinates, which I could allow for the height of the menu and toolbar. Using DrawText I'm losing the first two lines of data, is there any way to allow for the height of the menu and toolbar. I need to use DrawText, because of additional functions it provides. Thanks, Ewayne paintem: push offset ps push hwnd call BeginPaint mov [DevCon],eax ;load device context push offset rect ;rectangle structure push hwnd ;window handle call GetClientRect ;get size of window push DT_EXPANDTABS or DT_WORDBREAK push offset rect ;device context push offset msgbuff ;buffer length push offset msgbuff ;address of input buffer push DevCon ;device context call DrawText =============================================== Subject: DrawText Date: 10 Oct 1998 00:53:14 From: hutch Ewayne, using GetClientRect() gives you the dimensions of the client area and DrawText() is drawing to the client area without allowing for the toolbar. This is why you are loosing a couple of lines. You will need to calculate the area where you wish to place the text, put it in a RECT structure and use that in the DrawText() call. Below is straight out of WIN32.HLP ------------------ lpRect Points to a RECT structure that contains the rectangle (in logical coordinates) in which the text is to be formatted. ------------------ Good Luck hutch =============================================== Subject: DrawText Date: 10 Oct 1998 03:12:58 From: Ewayne OK how do I change the RECT structure, I know what the coordinates should be and I've tried several different ways to change the structure, but it just smiles at me and doesn't change anything.

Resource editor :) Date: 10 Oct 1998 12:09:39 From: hutch :Which is the best resource editor for win32 asm programming? :I know it's possible to 'hard-code' all menus in asm source, but :is't easier to use a resource editor. So, plase tell me which is :the best. : :Regards, :DynamiTe DaN Dan, You can get the Symantec 32 bit resource editor from Iczelions site and it works OK, has a bad habit of renumbering static controls where you type -1 to 65535 but does most things well. You are far safer to work in numbers with control IDs and you will need to strip the C++ junk out of the RC file that it generates. If you are writing in MASM, you will need the win98ddk utility, CVTRES.EXE to convert the RES file to an object module which you then link into the EXE. BRW45 works OK but has a piggish dialog editor and you will need to ask one of the TASM guys how to link it in with the Borland tools.

Does cvtres.exe offer some advantage over the normal link method? Regards, Iczelion =============================================== Subject: cvtres.exe Date: 10 Oct 1998 20:32:16 From: hutch Iczelion, I use the coff linker out of the DDK and it does not have a documented syntax for resources binding. I knew from the technical data that resources in 32 bit PE files are linked in as obj modules so I tested the CVTRES utility and that is what it does, converts RES format files to coff modules. I don't know if that answers the question but I don't have the earlier version to compare it to. hutch =============================================== Subject: Linking Resources Date: 10 Oct 1998 20:53:08 From: RudeBoy when i use masm i just link the .res file, just put it on the command line to link like an object file. and as far as tasm goes, the .res file can be linked in directly also. after the import32.lib on the command line, you need two commas and then the name of your resource file. this is pulled from my makefile: tlink32 -x /V4.0 /Tpe /aa /c $(LINKDEBUG) (OBJS),$(NAME),, $(IMPORT),, $(RES) hope that helps, RudeBoy =============================================== Subject: Linking Resources Date: 11 Oct 1998 12:13:18 From: hutch RudeBoy, thanks for posting the TASM data. I am using the DDK link.exe and have no technical data for it as the options are different from the earlier OMF versions. It only has the command line help which does not give a syntax for linking RES as against OBJ files. Link /SUBSYSTEM:WINDOWS %1.obj rsrc.obj Link /SUBSYSTEM:WINDOWS %1.obj rsrc.res Linking either the RES or converted OBJ file works but I am left with no data as to why M$ supply CVTRES.EXE to do the conversion. When I have a bit more time, I will test a number of options to see why it is supplied. It may allow more than one OBJ with resources to be linked ? hutch =============================================== Subject: Invoke CreateFont Date: 12 Oct 1998 19:56:30 From: Ewayne Can I use invoke CreateFont to change the screen font if I'm using SendMessage to display the text on my screen?

Try "invoke SendMessage,hwndEdit,WM_SETTEXT,NULL,ADDR pMem" to see if there is a difference. For large quantities of text you have to use SetWindowText() but just make sure you are passing an address for the text. If you are using GDI functions for display, you use Device Contexts but with a richedit control, the control has this functionality built in.

EDIT v RICHEDIT depends on what you want to do. Richedit has built in drag & drop, will open much larger files and if you feel like climbing through win32.hlp, it will display formatted text, colors, fonts italic, bold etc... a subset of rtf.

Date: 20 Oct 1998 23:15:06 From: hutch If you dump kernel32.dll, you can check if it is in the exports, if it is then you should know the sizes of the parameters from using it in Delphi. Depending on which assembler you are using, if you use the EXTERN syntax or similar, you should be able to call the function you need. You should also be able to use the, LoadLibrary() GetProcAddress() functions to call the API out of kernel32.dll.

In order to maintain consistency for a standardized label size, I need a mechanism for controlling the font size and spacing for any printer the user may have connected. The ASM 32-bit code I have written prints the data too large and with too great a spacing on my inkjet at home, but at work, on a laser printer, the character size as well as spacing is perfect, but the rows of data overlap and the spacing between the info for one label and the next is too close. Although 'Progamming Windows 95' provides a wealth of info on fonts, it seems to be more geered to video and I cannot see the correlation to printing.

I left out one very important aspect... (guess it was too late at night :) When the DLL calls a DDE service just to "DdeConnect" during the time that the user sent an WM_CLOSE to the main window, DdeConnect freezes. I just added #5 pointer to the bottom (scroll down it's in TestFunc). DDESend is really a function that connects to a server via "DdeConnect" and then XTYP_POKE the data, and DdeDisconnect. Gosh, sorry if I've left out this big clue :) The problem isn't the DLL function not being able to return, it's the DLL function not being able to return because of "DdeConnect" if and only if the user issued a WM_CLOSE. I'm not sure how DDEML keeps a tab of anything, but it shouldn't freeze at all! If the DdeConnect was made in the TestWorkerThread at #3, it will work--amazing. My workaround got me to send a pointer of DDESend to the TestFunc in the DLL. I didn't know if the DLL was dying or anything when it tried to call DdeConnect when the main program/thread already got issued WM_CLOSE / WM_DESTROY. So, this pointer used the main program's own DDE connection. This means that the main window/program handles all DDE itself. Now we can rule out that the DLL TestFunc had problems of anything related to initializing it's own handles when connecting with DdeConnect and etc. All the DLL TestFunc at #5 is to jump to the main program's own DDESend, the real one. The expirement came out to be the same. When the program was closing up, any accesses to DDESend from the DLL froze/crashed while the same DDESend executed from inside the main program (#3) worked fine. Something tells me that the DDEML doesn't allow DLLs to use DDE. Anyone got any bright ideas?? My bulb just went out . . .

Then, after some experimentation I was able to create the tab control. The problem that I am now having is when I try to insert an item. Since I can't find the macros that would be in commctrl.h I decided to just use the macro's definition and go from there. The definition is as follows: #define TabCtrl_InsertItem(hwnd, iItem, pitem) \ (int)SendMessage((hwnd), TCM_INSERTITEM, (WPARAM)(int)iItem, (LPARAM)(const TC_ITEM FAR*)(pitem)) I then use this bit of code which gives me a general protection fault in commctrl.dll: invoke SendMessage,hTab,TCM_INSERTITEM,0,ADDR item If anybody out there has successfully created tab controls I would appreciate it if you could give me a hand on this.

However I have the 'original' documentation on my page at virogen.cjb.net. It's fairly complete and has served all my purposes. :::2. Does the final section need to be padded, or not? The final section's virtual size does not need to be aligned with the object alignment, however the physical size does need to be aligned on the file alignment. So it's a good idea to pad up to the next alignment boundary. You might be able to get away with not doing this under win95/98, but winNT is much more picky. latez virogen =============================================== Subject: Print Preview Date: 17 Nov 1998 15:03:50 From: Ewayne Is there any way to do a call to some function or program to do a print preview?

Thanks. Cynical Pinnacle =============================================== Subject: Help with printf Date: 21 Nov 1998 00:44:40 From: Iczelion I have several suggestions. First, you should not link your asm program with C library, it bloats up your executable to the point that it defeats the purpose s of assembly language: speed and size. Second, you should be aware that C functions use C calling sequence which pushes parameters from right to left and the caller is responsible for balancing the stack after the call. You specify the default calling convention as stdcall and you don't change the calling convention of printf to C. After the call, you should clean up the stack by: add esp,4 Since you push the address of MyString on the stack. Third, you'd be better off using Win32 API functions, your program will be smaller since the functions reside in various system dlls. =============================================== Subject: Windows assembler without Win32 APIs Date: 21 Nov 1998 02:28:57 From: virogen ::Anyone try this before?

I'm beginner in assembly programming. I Have always thought that programs written in assembly are small. But it seems thats not the case in Win32. Smallest win32 programs I could do is 4096 bytes long and is doesn't even do anything yet. Then I write few more lines and the EXE is suddenly 8192 bytes and so on.

Remember that your HDD cluster size is probably bigger than 4k anyway so there is no real space gain. Making the exe smaller can impact loading speed. You're probably better leaving it at 4k. I think MASM creates smaller files. =============================================== Subject: Win32 assembly with TASM 5.0r Date: 2 Dec 1998 23:10:02 From: hutch Sami, MASM pops a working window at 2.5k and a template with a menu & icon at 5120 bytes so there may be some difference in the basic size of the assembled code. I would not worry too much while you are learning how to use TASM as there are a lot of very good TASM programmers around who have posted a lot of very good code to use as examples. With some practice, you will learn the options of TASM which should give you more control over the assembled size.

What you discussed I recall from writing the DOS pgm to control one machine with one computer. Since all the advice I've seen says avoid the DOS interrupts, how about the function: call ClearCommError, hComm, OFFSET dwErrorMask, OFFSET comstat where comstat is a structure. Would this work?

Dave =============================================== Subject: Testing serial port Date: 14 Dec 1998 06:23:14 From: hutch Dave, It seems that the DOS interrupts work in win 95, maybe win 98 and not in win NT4,(access violation). A quick look at the APIs you mentioned says use the CreateFile() function to get a handle to a device (com1, lpt1 etc..) and give the functions a try. Generally, hardware access is very poorly supported in WIN32 so you have to try and pick your way through badly dopcumented APIs. If you think that these functions will give you the control that you need with another computer, it is worth a try but I would be testing every return value on the way to make sure they are working. hutch =============================================== Subject: Testing serial port Date: 14 Dec 1998 22:54:09 From: Dave Hutch, are you saying I can directly use the software interrupt 14H without having to switch to 16-bit coding. If that is OK, naturally it would be easier (I'm already familiar with DOS ASM) and it would simply be testing bit 7 of the AH register for a time out?

Thanks get the windows 98ddk for the assembler. =============================================== Subject: Win32 flat memory model Date: 31 Dec 1998 17:20:31 From: GEnius I want to discuss about the Win32 memory model organization. I've chosen to talk about this subject, because i've not found any information about this. So after read some Intel source the m$ ddk and some windows reverse, i'll able to try a first conclusion. Win32 at ring 3 uses the flat memory model, whereas at ring 0 it uses normal memory addressing with the paging enabled. But before i continue, i want to remind the protected mode-addressing model: In protected each segment is defined by the programmer, it can choose the base address, the size of the segment and other things such as privilege level. The structure that defines these attributes of a segment is called DESCRIPTOR. The descriptors are situated in two table the LDT (local descriptors table), GDT (global descriptors table). There is only one GDT and more LDT defined at execution time. The pointer of a LDT is in LDTR register and the pointer to GDT is in GDTR register. You can select a segment loading a SELECTOR in a segment register. The selector is a 16 bit data that indicate the descriptors table chose (LDT or GDT), an index to this table and the requestor's privilege level. Therefore you can address a memory location by the couple Selector/Offset (the offset can be 32 or 16 bits, in 32 bit environment is 32 otherwise is 16). When you modify a segment register with a new selector, the 80x86 read the descriptor information and makes a LINEAR ADDRESS before it accesses memory. The linear address is created by reading the segment base field of the descriptor and adding the offset. LDTR or GDTR---->|DESCRIPTORS TABLE| | | SELECTOR ----> | entry.Segment_Base_field + OFFSET = LINEAR ADDRESS Now if the paging is disabled the linear address are the same of the physical address. Therefore if the paging is enabled the linear address is different from the physical. In this case, the linear address is viewed from the 80x86 in this way: Linear address 32 bit: Bits 0..11 = OFFSET Bits 12..21 = PAGE Bits 22..31 = DIR Linear address = DIR:PAGE:OFFSET The paging in the 80x86 is implemented in this way, a page is generally of 4k, and there is a two level table of pages in which each entry specify the page frame address, protection and so on. In the Cr3 register there is the pointer to the 1 level page table (the dir table). The entries of the dir table points to a page table (the 2 level page). The physical addressed is created in this way: Linear address = DIR:PAGE:OFFSET CR3 ------>| PAGE DIRECTORY | | | DIR -----> | entry ---------| -> |PAGE TABLE| | | PAGE---------------------------->| entry.frame_address_field + OFFSET = PHYSICAL ADDRESS Note this scheme is valid only if the page is of 4k and the extending address is disabled. The FLAT addressing model is a simple model used to "bypass" the segmentation. A flat address model is created by assign two segments one for data and one for code with a Segment base of 0. So your OFFSET are just like linear address, in fact the Segment base is 0 and so the offset + 0 = linear address! There are several implementation of the flat model with more segments, with paging enabled or disabled and so on. Note that there is no way to disable segmentation only the paging can be enabled or disabled, the flat model don't disable the segmentation only "hide" it! For more information about this argument please read the Intel documents. And now the win32 implementation of the addressing modes of the Intel chips. At ring 3 Win32 use the flat addressing model, two main segment where created one for code and one for data, both with base address set to 0. Win32 use the paging so the linear address is different from the physical (each page is 4k). For the nature of the flat addressing model at ring 3 processes can see only the addresses mapped in their address space and nothing else! There aren't any win32 API (i expect) that allocate a GDT/LDT descriptors, but if know where a descriptor in GDT/LDT points, you can load the selector in a register segment and you can address this region of memory! As result of this flat addressing model implemented at ring 3 you are able to write in the code segment which is possible because the data and the code segment have the same base address and consequently the same address. Note that the 80x86 are not able to write in a code segment! Win32, logically, cannot use only the flat model; in fact, at ring 0 you may use the selectors. Each VM has an own LDT and use that for memory access. In the LDT, there are segments of 32 and 16 bits, this is due the fact that in Win9x you can execute the 16bit code. Naturally, also in ring 0 the paging is enabled so the physical address is a bit more complex to create. At ring 0 you can allocate a single page and generally is the "page" the unit allocation base. In fact some VMM service required a page number as argument, this page number is the combination of DIR:TABLE of the linear address. For example if you have a linear address, you can get the page number simply with shr linear_address,12 so the DIR:TABLE are shifted to right in the position of the offset. Finally, this is the linear address space organization of Win9x (stolen from DDK): " The system divides the linear address space into four areas, called arenas, each of which is managed differently. The DOS arena spans linear addresses in the range MINDOSLADDR (00000000H) through MAXDOSLADDR (003fffffH), and is used for virtual machines (VMS). The DOS arena is itself divided into several areas. For more information about the DOS arena, see V86 Address Space Mapping and Allocation. The private arena spans linear addresses in the range MINPRIVATELADDR (00400000H) through MAXPRIVATELADDR (7fffffffH). This arena is used for code and data that is private to a Win32 process. The mapping of pages in this arena to physical storage depends on the current memory context, as does which pages are reserved. The shared arena spans linear addresses in the range MINSHAREDLADDR (80000000H) through MAXSHAREDLADDR (0bfffffffH). This arena is used for ring-3 shared code and data, such as 16-bit Windows applications and DLLs, DPMI memory, and 32-bit system DLLs. The mapping of pages in this arena does not depend on the current VM or memory context. The system arena spans linear addresses in the range MINSYSTEMLADDR (0c0000000H) through MAXSYSTEMLADDR (0bfffffffH). This arena is used for code and data for the VMM and virtual devices. The last four megabytes of the linear address space are permanently invalid and is not part of any arena. Because zero is a valid address, you should use an address in this permanently invalid region to denote an invalid pointer. To be extra safe, you can use the value 0xFFFE0000, which lies right in the middle of the invalid region. " This explanation there isn't very complete, but i hope that can be useful for every win32 coders! Any addition and/or correction are appreciated! :-) Merry Xmas, and Happy New Year! :) Excuse my BAD English :( ThanX Kill3xxx Iczelion =============================================== Subject: Progress-Bar in ASM code (Win32) Date: 2 Jan 1999 21:32:26 From: Marcello Hi, How do I realize a progress-bar in asm code with TASM 5.x ?

Normally in win98 they are refering to WMM. =============================================================================== From: Knotty Dread Subject: Visual Assembler Date: 29 Jan 1999 22:34:52 Hello fellow sentient beings...

Date: 30 Jan 1999 15:36:41 Greetings....I'm having a problem...OFten times when I assemble something it works, but when I link it saysf"WARNING! NO STACK!".......I'm using TASM, and am wondering what this means....Its an ASM keygen (My first ASM program really) and whene I run it it says than an error has occured and it shuts down---It displays the first logo and 'Enter your name:' before crashing.....To be honest I'm just ripping the keygen material and copying the 'enter your name' things from other keygens (and the code to read vaules from the keyboard)...One more thing---When retrieving a string from the keyboard, does it ALWAYS have to go to DX, or can you send it to lets say ESI??? (I need it in ESI for this keygen...) any help will be appreciated!!! ------------------------------------------------------------------------------- From: "John W." Subject: re: Warning! No stack! (???) Date: 23 Feb 1999 09:28:40 This depends on a lot of things. When I code a .com program this always happens and can be ignored because a .com program doesn't use a stack segment. (But then you should use something like exe2bin.exe to make it a .com program.) If it is a Windows program, perhaps: 1. You haven't declared your LOCAL variables. According to the MASM Programmer's guide (Sorry), "To use a local variable, you must save stack space for it at the start of the procedure." For example, in MASM, you declare LOCAL variables and save space for them, by declaring them as follows: LOCAL wc :WNDCLASSEX LOCAL msg :MSG ******* (etc.) The format of the LOCAL directive has the syntax LOCAL label [[[count]]] [[: datatype ]] 2. You haven't defined the model as .flat or declared the processor type, i.e. .386, .486, etc; or, 3. Perhaps TASM is just twitchy and feels naked unless you have some dummy .stack statement even when using the .flat memory model. Such a statement is not necessary in MASM. This is probably the case because if the program still works without being buggy, its just complaining in a way that MASM doesn't. I hope this helps. =============================================================================== From: hiroshimator Subject: MASM or TASM Date: 31 Jan 1999 20:46:35 Hi everyone, until now I only used ASM in DOS for small programs and thus not very often. I always used tasm, for interface and usage reasons (don't ask me why sometimes I have weird feelings ;) but now when wanting to program for windows in ASM, I wonder which assembler to actually use: MASM or TASM. Could anyone point out the biggest difference or the reason why I should use 1 of them for win32 programming, so I can give myself a good start? thank you very much, -H- ------------------------------------------------------------------------------- From: rudeboy Subject: re: MASM or TASM Date: 2 Feb 1999 17:26:08 it is really a matter of personal preference whether you use tasm or masm. i would recommend trying both with small programs and seeing which one you like better. neither one really works 'better' than the other, it just depends on what you want to do and which one 'feels' better to you. personally i use masm and for a beginner in win32 asm i would recommend picking up hutch's masm32, it has some good example code and everything you need to compile win32 asm progs.

What I'm aiming for is: I want a program that, when started from a dos box, inherits the stdout of the dos box like any normal console app. But when its started by Run... or explorer or a shortcut, it knows it and stops itself from opening a console. I also want the process to be run "detached" so that it returns to the command line immediately but maintains a HANDLE to the dos box's stdout. So, the first guess would be to have a /subsystem:console program, call GetStdHandle() and check if it returns INVALID_HANDLE or not. If it returns a good handle, we're in a dos box and we've got the handle to stdout that we want. But the dos box is waiting for us to terminate, when we really wanted to be detached anyways. And if we're run from Run.. or the GUI, a dummy console is opened by default and its annoying. Now, my second guess is to have a /subsystem:windows, but those are always CreateProcess'd as detached, and according to the Win32 API docs I have, detached processes never inherit their parents' console handles, which is what I want. Basically I want, either, a /subsys:win app that, if called from a dos box, gets a handle to that box's stdout. Or, a /subsys:console app that doesn't open a dummy console if its _not_ started from a dos box. I realize there's a problem with having a volatile handle, ie. having a handle to a dos box's stdout and then having the dos box closed and then, after, trying to use the handle... but whatever, does anyone know what I'm talking about? Why do I want to do this? I don't actually remember, but its interesting to me and someone might know. frink =============================================================================== From: hiroshimator Subject: platform SDK?

Once you've sorted them both, then you can take advantage of the expected dataset. Are the possible values very small, with a large dataset? (i.e., only 0-9 possible, with 10,000 elements?). If so, then you can tokenize each unique element and count tokens, comparing the qty of each token to give you a total qty of difference. I'm assuming that the arrays have to be the same size. If not, then you'll have to handle the differencing cases, etc. If there are a large # of possible values, and a large # of elements, then you're pretty much stuck with a sort and a compare. You can tabulate as you go on, incrementing thru the array and comparing item-by-sorted-item. It's not going to get much faster than that. btw, note that some instructions are slower than others depending on CPU type. In particular, the SCASB and CMPSB instructions are quite slow on 586+, even when used with REPNE, etc. prefixes. In an example shamelessly stolen from Agner Fog's Assembly optimization manual (highly recommended), replace it with loops. This example is actually a strlen() replacement. It's easy to modify into a comparison, however. Example 1.10: STRLEN PROC NEAR MOV EAX,[ESP+4] ; get pointer MOV EDX,7 ADD EDX,EAX ; pointer+7 used in the end PUSH EBX MOV EBX,[EAX] ; read first 4 bytes ADD EAX,4 ; increment pointer L1: LEA ECX,[EBX-01010101H] ; subtract 1 from each byte XOR EBX,-1 ; invert all bytes AND ECX,EBX ; and these two MOV EBX,[EAX] ; read next 4 bytes ADD EAX,4 ; increment pointer AND ECX,80808080H ; test all sign bits JZ L1 ; no zero bytes, continue loop TEST ECX,00008080H ; test first two bytes JNZ SHORT L2 SHR ECX,16 ; not in the first 2 bytes ADD EAX,2 L2: SHL CL,1 ; use carry flag to avoid a branch POP EBX SBB EAX,EDX ; compute length RET ; (or RET 4 if pascal) STRLEN ENDP I hope that helps, __Calaban =============================================================================== From: PeterBee Subject: Win32.hlp Date: 14 Feb 1999 18:47:23 Where can I find a Win32.hlp?

If the file is less then 1,000 lines the speed is acceptable, but anything over 2,000 lines the screen update takes several seconds. The file is loaded in memory where I do the search for the syntax text and then translate that address to the screen buffer where I do a EM_HIDESELECTION (only one time). Then I do a EM_SETSEL and then a EM_SETCHARFORMAT, SCF_SELECTION and loop through that procedure untill I've reached the end of file. I've even tried LockWindowUpdate.

I'm trying to build my own compiler (of my own language), and what I need is table of all instructions of 80x86 processors family. Let's explain what I'm looking for: As far as I know, all the instructions in the Intel family of processors are composed of bitfields, which define the width of operands (if it uses AL or AH or EAX ...), the "codebyte" of operation itself (MOV, ADD, SUB,PUSH ...), which registers are involved, the direction of the operation (mem-->register, register-->mem, immediate-->register...), and additional immediate value bytes and/or address (offset) bytes. Well what I need is a table explaining, for each ASM command, the bitfields for it so I can build a sequence of bytecodes from, say, this line of code: MOV EAX,[BP+4] or ADD EDX,ECX I know I can do it by using a table of "precalculated" values for each command combination, but I prefer to use the bitfields since the table will be VERY big and even preparing it is no easy task. Again, I'm not looking for making an assembler, (but I'm thinking of that too, so maybe :) I'm just looking for a simple way to build machine bytecodes for my compiler. I'm certain that someone should have some article (in any text format) describing the bitfields of the ASM operations, ot any link to place on the net where I can get it. If you have something like that please send me the article or some address on the topic to my mail address: blev50@hotmail.com Note: I REALLY need it to describe at least up to .386 instructions(!!!) since I build the compiler to make .EXE's for Win95/98. Thank you very much! -------------------- P.$. ;o) If you send me this info, and I'll succeed in my project, I'll put your name on the "credits" list if you wish ;) I'm not planning to involve additional people in my project, since I make the compiler for myself, but it is possible that I will publish it as freeware, too. If you interested the compiler is intended mainly for Win32, with C++ like syntax, but much more meaningful ;), and will be very object oriented, supporting all the Win32 API in a way much more handy than current C++ or ASM compilers give. It should be *VERY* fast, faster than any current compiler on the market (at least I hope it will be)... Instead of leaving you to worry about the complex API calls I plan to incapsulate objects like Windows and Controls in simple to use and extend classes. Now it's in the early development stage, I use Turbo Pascal 7.0 for DOS *grin*, and succeeded to parse "pascal"-like text to create perfectly working PE (Portable Executable) .exe file for Win32 that uses some API calls. I'll need to add some sort of type checking and struct/class management, but this will not be *too* hard. The TP7 is surprisingly easy and handy environment, but for serious project I think I'll port the compiler as a Unit to Delphi to support long file names and include built-in IDE with editor, resource compiler... shortly,make a complete IDE out of it. * * * END * * * =============================================================================== From: AsmFreek Subject: Win32.hlp version?

There's RegQueryInfoKey which, again is pretty self explanatory in a help file, and gives you basic overall info on a key such as how many entries are under a key name, length of names, etc. Then there's RegQueryInfoEx which will give you the data in a key's subkey. include advap32i.inc and includelib advapi32.lib for your functions. =============================================================================== From: drkpurple Subject: DLL written in TASM Date: 15 Mar 1999 04:54:31 How do you export functions in a dll written for tasm and what are the commad lines to link it. thnx for your help =============================================================================== From: Jeremy Subject: Windows Access Date: 16 Mar 1999 01:07:32 Hey all. I have a few questions for all of you, and I hope you can answer them. =) Here goes: #1) How do you create graphics inside of a Window (preferrably working with Windows NT 4.0 but Windows 95 or 98 will be helpful). I assume you have to create a sort of canvas first, but I don't have any idea how. #2) How do you read access from the keyboard, mouse, gameports, or similar input devices without having some sort of input box or text field? #3) How do you access the sound card without playing an audio file? Thanks for your help!! ------------------------------------------------------------------------------- From: dude Subject: re: Windows Access Date: 17 Mar 1999 09:18:48 :#1) How do you create graphics inside of a Window (preferrably :working with Windows NT 4.0 but Windows 95 or 98 will be :helpful). I assume you have to create a sort of canvas first, :but I don't have any idea how. Get a Handle to the Device Context (HDC) of the Window is the easiest. Watch for WM_PAINT msgs and hahdle them in there. Or, Create a Device Context in memory, do GDI functions on the device and BitBlt them to another real window's HDC. There's Direct Draw API also. Many ways to do this. For Win32 API, look into CreateDC, GetDC, CreateCompatibleDC, all the GDI functions like BitBlt, LineTo, CreateDIBSection, etc. :#2) How do you read access from the keyboard, mouse, gameports, :or similar input devices without having some sort of input box or :text field? SetWindowsHook(), preferably in a DLL so you can spy on other threads. Or write a VXD to do it. :#3) How do you access the sound card without playing an audio :file? Not much good at this one. Have run across it more looking at DirectDraw code, though the win32 api does contain some functions for sound card stuff. The SDK has some wave stuff too. ------------------------------------------------------------------------------- From: Jeremy Subject: re: Windows Access Date: 17 Mar 1999 21:39:46 Thanks for the help, but I still have a few more questions. #1) How do you create a DLL or a VXD, and integrate it into the program? (I'm VERY new to Win32 Assembly, but I'm learning. =)) #2) Is there a way to DYNAMICALLY load DLL files? In case that's confusing, what I mean is can a user choose which DLL files to load and which not to without having a list of all the possible DLL files in the program itself? #3) If the answer to #2 is no, is there a way to open a file with Windows, and have it be able to execute code in that file? I know protected mode can be very difficult with privilage levels. Thanks for the time! ------------------------------------------------------------------------------- From: wbms Subject: re: Windows Access Date: 18 Mar 1999 19:59:20 :SetWindowsHook(), preferably in a DLL so you can spy on other :threads. Or write a VXD to do it. VXD is a big head pain :) So it's better to use SetWindowsHook(). But how to use SetWindowsHook() without .dll? ------------------------------------------------------------------------------- From: dude Subject: re: Windows Access Date: 19 Mar 1999 10:23:25 To use it without a dll, you have to be hooking msgs from your own module. Like a thread you create and the HookProc is in your own code, you don't have to use a dll for this. If you don't own the thread though, the HookProc must be in a dll. Sounds more like a debug feature when it's used in your own code. As for the other guy wanting to dynamically load dlls, sure, you can use LoadLibrary if you want. But since you are new to Win32 coding, I'd suggest getting a good Win32 API book, like Programming Windows 95 by Petzold or Advanced Windows by Jerry Richter. Those two will help you along, if you want to do VXDs, try Systems Programming for Windows 95 by Walter Oney. These are all great books to help you. If you want a quick start, lookover Iczlion's ASM page, he has some tutes there that are great and help you in many areas from easy to adv, one happens to be how to load a dll and call it by ProcAddress or by statically binding the code in your exe. Good luck! ------------------------------------------------------------------------------- From: wbms Subject: re: Windows Access Date: 19 Mar 1999 17:53:41 There is a good sample on a Stone's page as .dll example and even with SetWindowsHook(). coding, I'd suggest getting a good Win32 API book, like Programming Windows 95 by Petzold or Advanced Windows by Jerry Richter.

You can use message hooks like journal hook, etc. But there is no winapi hook. That's why you have to find some devious undocumented way to do that. ------------------------------------------------------------------------------- From: Iczelion Subject: re: Win32 Api hook Date: 21 Mar 1999 14:37:50 Funny this subject came up, because I am wanting to make such a spy right now. *Is* there an undoc way? I have d/led spies and looked over alot of code on the win sdk and I see alot of msg spies, but I see no real function spies. If there is a way Iczelion, can you point us in the right direction? I don't have alot of time to spend online for phone reasons or I would have dropped by #win32asm and asked there. Basically, all I want to do is not only be notified of posted events to the system, but say when an app calls one of the api funcs from the system dlls and know which func it called. I have some vxd code that looks over threads and stuff, but not anything that peers into actual calls. Is it possible for this to be done in a reasonable way? I had once written a winsock.dll in C that just got the proc addresses of the funcs out of the real winsock.dll and forwarded the info to the calling app and then wrote to file the functions called. This got hairy and I couldn't handle all the private funcs of course. Any way other than this to do it that you'd be willing to hint at? You want a global api hook. And there is some portability problem here. You can code a global api hook under Win9x by patching the system dlls at the entry points of the functions you want to monitor to point to your own code. But I don't know about NT and my guess is that it will not work on NT. I haven't done any research about VxD yet so I can't tell you if it's possible for a VxD to trap function calls. =============================================================================== From: Shadow Subject: win32 console print ? asciiz string?

I have done something similiar this way by using CreateFile making it a console and then writing to it, but it was in c. Hopefully I can get NT up and running on this thing sometime today and install masm and vis c++ and I'll look at it and see how it works.

If you return 0 in eax, the richedit control will continue with the operation but if you return a nonzero value in eax, richedit control will terminate your operation. In your case, you should check if the end of file is reached. If there are still some data left in the file, you must return 0 in eax. Since ReadFile returns 1 in eax on success, your richedit control will not process your data. ------------------------------------------------------------------------------- From: Ewayne Subject: STREAMIN from memory ?

It Page Faults when I try it with reg asm calls. From what I gather, you must include vxd compiled code using VxdCall or DosCall funcs. Or you get the offset into Kernel32.dll to those int calls and make a func pointer to them and call it *VxdCall and use it. MS toook out the calls by ordinal, then they took out calling any funcs to that dll by ordinal. But, remember they patch and change code when they want and it will break existing code.

A PE file has a header followed by an array of "sections". Sections are what segments used to be under Win16. Your code goes in code section, your initialized data is in another section and so on. When Windows loads a PE file, it reads the PE header to see where each section is located in the file and how large it is. Just adding data to the end of file won't help because the PE loader will ignore it. You have to increase the size of the section you appended data to. Just get hold of some PE file format manual and study it. =============================================================================== From: bTo Subject: Creating Custom Window Borders --&-- titleba Date: 5 Apr 1999 19:58:01 Here...

Thanks, Geoff ------------------------------------------------------------------------------- From: Subject: re: Dll's Date: 9 Apr 1999 12:55:50 i dont know if there is such a program. but to use a function from a dll, just use LoadLibrary to load the dll. Then use GetProcAddress to get the address of the api, then call it. The only problem is to know how many parameters to pass to the function, but that is easy with trial and error i guess. ------------------------------------------------------------------------------- From: Calaban Subject: re: Dll's Date: 13 Apr 1999 02:20:20 From within ASM, you have to either deal with the format directly, or use a tool like "lib.exe" from MS compilers to create the .LIB & then take something like hutch's "L2inc.exe" tool to create a .INC file that you can include in your ASM program. I don't know of any other way than these two methods. Fundamentally, you need a list of arguments, and the size of those arguments. With most DLLs that are part of an API, you can create a function prototype very easily. With a 3rd party DLL that is undocumented, you're pretty much stuck with tinkering with it in order to figure out what the parameters are for (after you have the size & qty of arguments). -Calaban =============================================================================== From: Racso Subject: Fixing Windows Date: 8 Apr 1999 19:49:42 Is there a way to fix a window, so it can't be resized, but it can be moved about?

Well when i compile it, it makes a dll file. Thats fine... I'm trying to call this dll from VB but it keeps saying it cant find the file name ->name of the dll file. I put it in windows\system, everywhere but same thing. So i start looking at other dll files (using properties in win95) and i notice they all have a VERSION tab which tells the company name, version, name etc, except, ONLY MINE DIDNT. I then was kinda figuring out that i had to use tasm32 and tlink32 instead of tasm/tlink... so i'm switched and set all the parameters that were needed and now it gives me the error->Fatal: 16 bit segments not supported in module dllwin.ASM So now i'm looking through everything and FIND some predefined symbols in the help file of TASM called @@32Bit <-- I want to know what this symbol is (actually i know what it is) but i want to know where do i place it, in the .asm file? the .def file? in the makefile? i dont know where and i'm sure i need this to fix that 16bit problem. Please help i'm in need. ------------------------------------------------------------------------------- From: Racso Subject: re: Help with MAKING DLL's in TASM HELP Date: 12 Apr 1999 20:40:33 Well, I don't use TASM. I use MASM, but I can tell you, if you put @@32Bit in the .asm file, you'll get an error. I would bet that you need to put it in the makefile, to tell the linker to use 32 bit segments when it creates the lib and dll files. I can't imagine a purpose for it to be in the .def file, but then, like I said, I don't use TASM. =) =============================================================================== From: SR1 Subject: Problem with win32 api :( Date: 13 Apr 1999 07:15:57 Why In my programs the API RegConnectRegistry doesn't work ? anyone can tell me an example of using it ?

You have two alternatives: 1.

You can't switch to Ring0 from a user mode application, since that would be a severe security issue. But writing a kernel mode driver will make it possible to communicate with it from a user mode application, and let the driver perform your Ring0 tasks. Keep in mind that you will need administrator rights in order to install a driver. Windows NT Device Driver Kit (DDK) will give you all the information you need to build a driver. If you don't know anything about NTAPI (NT's internals, a mostly undocumented API), you'll need to get learning. The DDK has information on the neccesary API's for driver development. // dOMNAR - See you all in #cracking / EFnet =============================================================================== From: Kuwala B Subject: Need Tic-Tac-Toe in assembly.....help...

It assembles fine under MASM 6.x. I've tried MASM32 v2 and v3. I don't know where to go to look for MASM32 updates, so I'm slightly stuck. Here's a modified example out of the MASM 6.11 book: ITEMS STRUC Inum DW ? Iname DB 'Item name' ITEMS ENDS item7 ITEMS 30 DUP () As I said, under MASM 6.11 this assembles fine, but under MASM32, this example stops on the 'item7' line and says "error A2187: must use floating-point initializer". I get the same error even if I change the 'item7' line to read: item7 ITEMS 30 DUP ({,}) Any clues??? I guess I might have to make an array of pointers and just use GlobalAlloc to reserve space for each structure definition I need, but I HATE losing time on a problem that should not exist! I spent three days trying to figure out what *I* was doing wrong - then I finally remembered that I had MASM 6.11 still installed and once I found that it worked fine there, I knew it was not my fault. Sigh. ------------------------------------------------------------------------------- From: Iczelion Subject: re: STRUCture/array errors in MASM32 Date: 18 Apr 1999 13:01:28 It looks like MASM 6.13 changes its internal method of defining default structure members.

Date: 20 Apr 1999 10:34:37 the data is sent to a hidden dialog window called "Restoring Network Connections" after connection. You have to call EnumWindows, in a thread preferably, and in your EnumProc, look for GetWindowText on every window and compare it against the "Restoring Network Connections" and then SetWindowsHookEx into a Dll passing it the threadID of the dlg box and hook whatever you want. Personally, I have had trouble getting this window to behave properly, it seems to unhook my hooks. If you watch quickly, you'll see it minimze to the tray after it becomes visible, then turn into your modem light icon. This is a most unusual window, I've not been able to duplicate this path of minimizing without making the tray do weird things. As for the API calls to start the dialing, look at all the RAS funcs, like RasDial, RasEnumEntries, etc. I have to say I haven't messed with this window since Win95, so I don't know what it does in Win98. Use Spy++ or WinSight to check the window out. BTW, you must use a dll to hook this dlg box as it's a seperate thread. Good luck! ------------------------------------------------------------------------------- From: Calaban Subject: re: Catching the DIAL UP Connection ...
