Hi im currently involved in a project and i need some help. Firstly is there any program that could extract dll files so that i could see the codes. i tried notepad but the words were scrambled.

Please explain what "codes" you expect to extract exactly...?

...I'm pretty certain that a function call into a linked file is just loading the right stuff into the registers, and then a jump to [some specific offset] into the dll file. There's no "code" to get, aside from the function offset (the name of the dll and the address in the dll of where that function begins).... I could be wrong though.

,,,,,,

Alternately you could try using a hex editor, or a disassembler--but neither of those will contain descriptive variable names, or code comments.

alrite let me get this straight, dll files do not have the source in it ( variables and etc)?

DLL files, in the easiest sense, are ONLY different from EXE files in that they contain no system loadable/callable entry point. They consist of precompiled functions and/or class objects. The only "source code" they contain is machine code.

Just use W32Dasm (or any other disassembler) and learn asm
