Hi,
Actully You need to ask this question in VB forums not in OS Issues. Just few days back only I faced this problem.

I resolved this issue by writing the C/c++ funcions like this..

__declspec(dllexport) long _stdcall MyFunc(HDC hPicDC, long *size_x, long *size_y)

Change the function prototype as per requirement.


Hope so this helps you.
