Essay

First of all, I want to tell your something Config SmartCheck. To use SmartCheck best
for cracking, you mst config it, but I won't tell you about config SmartCheck, you 
can find some Eternal Bliss tutorial about VB Cracking, his tutorials will useful for
you.....
Now, run SmartCheck, load the crackme in SmartCheck... Then you will the form show, 
There is 2 menu : Open and About, choose the Open/ Registretisen. You will see the 
text with the title is : Unclock Code. Now, type some fake unclock code, then see in
SmartCheck, you will see many event like : + Change
Click at '+', you will see something like this:
- Change
 Then you choose the menu: View/Show All Event. Then try  to find the function like:
__vbaVarTstEq , when you hightlight this function, look at the right window, you will
see a string : "TV Total". That is your unclock code. Now back the crackme, and type
"TV Total" as the unclock code, you will see the Name/Serial Textbox. Continue, type
some fake name, and some fake serial, I use: tnhuan as name,serial as : 123456789.
Then click the 'Check It' button, now return SmartCheck, you will see a event: +Click
Then click at '+', you will see many thing... Choose the function Left ( at finish 
event ). Look at the right window, you will see a string:"80332-13699-43334822513"
This string look like a correct Serial, so I will test is, with a name : tnhuan, I 
enter this string as a serial, and click 'Check It' button, but not happen. So we 
wrong...Why??? May be this string is only a trap. So I will choose menu: 
View/Show all Event. Hey, many thing will show. Do you see the function:__vbaStrCmp?
Hightlight this function, you will see at right window a string:"80332-13699-43334".
And this is real correct serial, why I know? Simply I enter it as a serial, and click
Check it button and wow... I see a logo, and the string: Registed by tnhuan.
That is all :
