Didn't see fit to put it in Reversing, its more of coding i think...

Well, i try to load a .DLL and, to load one of it's processes...i wrote a test cpp code just to check that the proc name really does exist and it was added to the .DEF and all...everything's fine...it returns a handle to the DLL and the Process, as you can see here.

what have i done wrong? :(

thanks.

Looks like you are pushing the address of the module i.e. offset hDLL when you should be pushing dword ptr [hDLL] or in your case

PUSH 40C500 ; "Init"

PUSH 40C530 ; hDLL

Call GetProcAddress

PUSH 40C500 ; "Init"

PUSH DWORD PTR [40C530] ; hDLL

Call GetProcAddress
