VB6 - P-Code Mnemonics Descriptions ?
 

Hi there,

I've been attempting to reverse an algorithm in an application using the excellent WKTVBDE P-Code Debugger, however, some of the p-code calls I'm unable to decipher, having searched on google and come up with only a few bits and pieces, I was hoping that some people on here might have some more information to help me out ?

Thanking You.....

Try:
hxxp://vb-decompiler.com/

You will find the codes broken down by Lead.

Also, be aware that there are three errors in that very large listing that haven't been corrected yet.

I suspect the next question is, "Which three?", but I don't remember off-hand, except to say that they were typos (what WAS I thinking?); I'd have to go review my notes.

However, you may only get a terse, semi-cryptic description of the pcode parameters, not a verbose explanation of how a given code actually works in terms of pointers, stack operations, return values, etc.

If the section of code you are interested in is not too long, I can try to do it by hand. Or, if you are sure the app is compiled to PCode, send the entire thing to me, and I'll see what I can do.

Dekompilling target possibly in Semi or VBParser (translate him to the VB)
- and then concentrate in wkt on known instruction or API .
Know all instruction in p-code is inhuman execution.(or superhuman) :D
( 2 Sarge - respect ;) )

"Know all instruction in p-code is inhuman execution."

Considering that all I have been doing for the last 3 or so years is learning PCode instructions, guess that makes me an "inhuman"?

Besides, if I had the target, I'd still use RACE; whatever PCodes it misses, I'd do by hand.

Maybe that just makes you "superhuman." :D
