How to?
 

Sorry for my bad english...

How can I find the part in an exe-file, where the event is handled, what i'm searching for, so that i can change it in assembler?
Is there a program which shows me in runtime, where the computer is in the code at the moment?

thx @ll

Yes. It's called a debugger, such as Softice, TRW, Ollydog, whatever. They allow you to view, locate, and change the code WHILE IT IS RUNNING.

Regards.

LordPE will convert between VA/RVA to File offset and back again if that's what you want.

Much thanks!
