I wrote my own lde. It is a proc, that returns length of current opcode in address given as an argument. I wrote it for enhancing ApiResolve (my other program) possiblities. Code is os independent (as it doesn't use any API). Hope someone will find it useful Smile

EDIT: v1.3.2 has many bugs fixed and is heavily optimized for speed

ApiResolve...lemme guess...rather than diassembling a function completely... it searches for the ret opode and finds out how many parameters the function returns Smile
Just a guess Very Happy
Great work Smile

Good guess Smile
The program searches opcode by opcode for ret. Searching byte by byte didn't work, but when I know how many bytes does the current opcode have I can go through them. But this thread is not about ApiResolve Smile

My DLL2INC does the same but it disassembles using UDis86...kinda slow...well extremely slow Razz
Here's something i found though...in kernel32.dll some of the api calls have more than one ret and they are not always the same.
I designed my DLL2INC to pick the ret with the highest number for a function because it seems to be always the correct number.
Note: I'm not planning to release this version of DLL2INC because it is in VB6....I'm still planning to ma ke a FASM version...when I have time Razz

Awesome, I kept looking for ADE32 by z0mbie but I couldn't find it /any where/. Thank you.

edit: Very clean code, well done.

I needed it for a C project as well, but I have since ported Reverend's code to POASM (basically MASM) so I can include it in my C project. But thank you!

why did you rewrite it to MASM to use it with C ???

Reverend: didn't know you are "in the scene" Wink
also note that "htb.team.prv.pl" doesn't seem to be working, you could fix NFO

Ah no, not MASM, there is an LCC based C compiler called "Pelles C", Pelle wrote his own assembler called POASM, it has a very similar to MASM syntax (I don't really like the syntax) but you can add ".asm" files to your project and it compiles them as an object and links with the rest of the C objects so only 1 compiler is required.

RedGhost: and why didn't you just add those few line and create "format MS COFF" instead?

Then I would have to compile with two compilers, manually edit the linker settings and copy and paste. Too much work, adding a few offset prefixes and modifying how proc is declared was easy enough.
