The IDBCreateSession interface is mandatory, so this // is a simple operation. // ///////////////////////////////////////////////////////////////// HRESULT myCreateSession ( IUnknown * pUnkDataSource, IUnknown ** ppUnkSession ) { HRESULT hr; IDBCreateSession * pIDBCreateSession = NULL; //Create a session object from a data source object. XCHECK_HR(hr = pUnkDataSource->QueryInterface( IID_IDBCreateSession, (void**)&pIDBCreateSession)); XCHECK_HR(hr = pIDBCreateSession->CreateSession( NULL, // pUnkOuter IID_IOpenRowset, // riid ppUnkSession )); // ppSession CLEANUP: if( pIDBCreateSession ) pIDBCreateSession->Release(); return hr; }
