!!!请教关于如何调用ＣＯＭ接口的问题!!!

Question

LRESULT hr;
hr = CoCreateInstance ( CLSID_templib,
                            NULL,
                            CLSCTX_INPROC_SERVER,
                            IID_Isport,
                            (void**) &pIAD );
试一下!!

Answer 1

DEFINE_GUID(IID_Isport,
0x9FCA89F9,0x6143,0x11d4,
0x96,0xdc,0x0,0xc0,0x4f,0x88,0xda,0x2b);
void CTestdialogDlg::OnButton3() 
{
// TODO: この位置にコントロール通知ハンドラ用のコードを追加してください
CoInitialize(NULL);
CLSID CLSID_sport;
CLSIDFromProgID(L"temp.sport",&CLSID_sport); HRESULT hr;
Isport *Isport;
hr=::CoCreateInstance(CLSID_sport,NULL,CLSCTX_INPROC_SERVER,IID_Isport,(void**)&Isport);
if(SUCCEEDED(hr))
{
Isport->run();
}else{
return;
} CoUninitialize();
}

Answer 2

get IID_Isport through using OLE View 

Answer 3

我不明白为什么不用IsportPtr pIsport(__uuidof(sport))????
the smart pointer
