Hi, Is it possible to read the assembly code generated my my exe file? If it is, how? (I''m using VS.NET) Thanks

get the intel specification for the asm byte codes and you will have a mapping of the data in EXE to readable assembly language.

Since one assembly instruction equals one machine instruction, you can simply decode the EXE bytecode using the mentioned specs.

Getting a disassembler will of course be easier.

IIRC, you can open (drag/drop) an EXE right into the Visual Studio IDE, and it will automatically format it into assembly code in an instant, along with hex byte codes.

You should be able to even step/trace the actual execution... go hacker!

Alternatively, MASM comes with a disassembler, IIRC. That should turn your exe into a big .asm file. It''s still somewhat hard to read, though, unless you know asm pretty well.

Also decompiles .NET applications into IL assembly.

If you are willing to spend some money, then IDA - The interactive disassembler is really the best. It has been very useful for me, when I have made editors for some games, and trying to hack the fileformats

The easiest way to see the generated assembly for a program you have the source code to is to turn on ''Assembler Output''(with source to make it easier to read) under project properties, C/C++ tab, then Output Files. Assuming you are using C/C++ of course (you didn''t specify language; you can use the other methods mentioned if you don''t have the source or aren''t using C/C++ though the option might be available for other languages)
