I've spent quite some time trying to get a DLL file to work by using the Interop.Call function, but it just won't accept it.

Here's what I have so far.

c code:

---

#include "stdafx.h"

#ifdef __cplusplus    // If used by C++ code,
extern "C" {          // we need to export the C interface
#endif

__declspec(dllexport) int __stdcall GetScreenSize(int avar)
{
    //some code here
    return 1;
}

#ifdef __cplusplus
}
#endif

I just want to get the dll to work so I can use it, but messenger plus will not call the function.
