위에 명시를 해줘야 다른 데서 이 MFC DLL Method 읽을 수 있다.
이제 가따 쓰면 끝 ^^;
아래는 MFC에서 대충 가따 쓰는 방법이다.
HINSTANCE hInst;
hInst = AfxLoadLibrary(_T("MailClient.dll")); // dll 로드
if( hInst == NULL )
{
AfxMessageBox( _T(" dll 로드 할 수 없습니다. "));
return;
}

int len = 25;
int ret2 = fun2(buf2,&len); // 서버설정
int ret3 = fun3(buf3,buf4); // 주소 설정

이런식으로 사용 한다.
