这是一本学习 window编程的很好的参考教材

#include <Windows.h>

typedef void(*FnPtrT)(char*);
#define EXPORT __declspec(dllexport)

BOOL APIENTRY DllMain( HANDLE hModule, 
                       DWORD  ul_reason_for_call, 
                       LPVOID lpReserved
					 )
{
     return TRUE;
}


EXPORT int fnImportingDLL(void)
{
	MessageBox(NULL,"Dll Function called!","From DLL",MB_OK);
	FnPtrT FnPtr = (FnPtrT)::GetProcAddress(GetModuleHandle(NULL), "ExeFn");
	if(FnPtr)
		(*FnPtr)("Messge From The DLL");
	else
		MessageBox(NULL,"It Did Not work :(","From DLL",MB_OK);
