Create and Initialize
//--------------------------------- // Create {{{1}}} object CComPtr<IAVObject>; spReader; HRESULT hr = Create_{{{1}}}(&spReader); if (hr != S_OK) return hr; //--------------------------------- // Query IAVProperties interface CComQIPtr<IAVProperties> spProps(spReader); ATLASSERT(spProps != NULL); //--------------------------------- // Set filename hr = spProps->PropsSet(L"source", L"filename.ext"); if(hr != S_OK) return hr; //--------------------------------- // Init Object hr = spReader->Init(); if(hr != S_OK) return hr;
Trace all object's properties
//Query IAVProperties interface CComQIPtr<IAVProperties> spProps(spObject); //Get list name=value pairs separated CR //for all properties of object CComBSTR cbsPropsList; HRESULT hr = spProps->PropsGet(L"\n", cbsPropsList); ATLASSERT(hr == S_OK); //Trace properties ATLTRACE2(atlTraceGeneral, 2, L"Qbject's properties:\n%s\n", spPropsList);
