Hi ,

It is wild guess. ( i need to do so because ur question is partial ).

In ur Release Build, Calling convention may not be __stdcall or byte alignment is
8.

In ur Debug build calling convention is __stdcall ( perhaps byte alignment is 4 ..are u passing structs ? )


Check the settings

Maybe you're supposing that the initial values of variables and member variables are zero. Use the compiler option /RTCu (Uninitialized local usage checks) and correct all errors that will appear in the debug DLL when you run the program.

Assuming that is not an ActiveX dll, and you export your functions as __stdcall:
Have you included a *.def file in your project where compiling the dll?
Attach your compiled dll, the one compiled in Release version. I'd like to see it.
