DLL __cdecl doesnt seem to work?

I am currently having problems with a DLL, the DLL will work fine in C++ however I am trying to make the DLL portable with VB so that my friends can use the DLL's made in C++ when they just need the power that VB cannot assign. Currently I am working with a Dynamic Linked Library, not Static. Im using the __declspec(dllexport) definition. I checked MSDN and they said that VB always uses __cdecl for API calling convention. However the DLL will run just fine in VB until the DLL has to return a value, then it all just crashes and the DLL doesnt get shut down etc.. I have tried adding the compile option Gd, and Gz (both seperate compiles ofcourse) and VB still gives the "Bad DLL Calling Convention" error, I am not quite sure what I am doing wrong in the DLL, here is a sample of what Im putting in the header file:

Code:

---

#ifdef __cplusplus
#define EXPORT extern "C" __declspec (dllexport)
#else
#define EXPORT __declspec (dllexport)
#endif

EXPORT int TestB(char *Say);

---

It's just a silly sample DLL that i've been working with to try to get it working with VB properly. "void" functions work perfectly, its when they have to return a value when it doesnt work properly.

wha'd are you on drugs?

you can't make a dll using c++ and use it with vb without linking it to MSVBVM60.dll

thus your way will not work, as MSVBVM60.dll accepts only cdecl statements specifically made by a microsoft devleoper(as in, the people in the company)compiler which is meant to make vb libraries, or made by vb professional itself

i tried to find a solution but i couldn't. i'm still looking

No, you're wrong. A quick search on google came up with: http://www.vsj.co.uk/archive/hovb-9905.asp

Thankyou Eibro and XSquared, the websites that you provided have been useful in assisting me create the DLL's compatible and taught me a couple other useful things. :)

aren't you going to thank me too? i'm the one who made people actually research:D

Yes.... thanks
