HI Mitchell,
just to give you an idea how such a DLL could look like.
(you have to modify your PrinterDemo.CPP a little and export the C++ function like shown in this little sample)
// testdll.h
#ifdef TESTDLL_EXPORTS
#define WDEXPORT extern "C" __declspec(dllexport)
#else
#define WDEXPORT extern "C" __declspec(dllimport)
#endif
WDEXPORT int fntestdll(void);
WDEXPORT void fninc(int* intptr);
and it's implemetation
// testdll.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include "testdll.h"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
// This is an example of an exported function.
WDEXPORT int fntestdll(void)
{
return 42; // what else
}
WDEXPORT void fninc(int* intptr)
{
++*intptr;
}
