How to use 3rd Party DLL which has WINAPI defined functions.

[Scott Youngren]

I'm trying to implement a dll into CVI which comes with its LIB and H file for NT.
A typical function:
BOOL WINPAPI GetExFastStatus (.......)
What do I do with the WINAPI

Windows2000
CVI 6.0

Hello,

At windef.h, WINAPI is a #define for __cdecl

Be sure to
#define WIN32_LEAN_AND_MEAN
and
#include

Should read:

#include windows.h
with the appropriate brackets

I would guess that the .h file for the third party DLL #includes windows.h, but if it doesn't, #include windows.h and/or windef.h before you #include the DLL .h file. Add the .lib file for the third party DLL to your CVI project.

So thanks to all who responded. The 3rd party DLL has been successfully implemented.
And I continue to learn how to make things work.

I am having the exact same problem as described here, but for some reason I can't get it to work. The error I get is "Undefined symbol '_Gx1838Initialize@12' referenced in "DC Source.c"". The Gx1838 is the function I am trying to use. I have included the .h file for the dll, the .lib file but it still cannot find it. I also have #include before I include the .h file. Do I need to do something with the .dll?

Thanks for any suggestions!
