Hi Friends,

I am cracking an vb application which display registration box on opening but when i hit enter it says invalid registearatin code. So i used the rtcMsg box api to trace the origin. It is breaking on that api but there is no return to origianl code. Even there is no string like that so how to deal with this kind of situation? Any solution.?

The program was compiled with P-Code.
You cannot debug it with ollydbg because its a pseudo code.

You can use the VB Decompiler Pro and the WK debbuger.

Hello,

If it breaks on the rtcMsgBox API, then you can simply press the <return from function> facility of your debugger. Continue doing so till you return BACK to the original exe/dll/ocx you are trying to crack.
