Then, after you have established the connection with the server, you need to advise your implementation
of the event interface:
hr = CoCreateInstance( CLSID_UwbAnalyzer, NULL,
CLSCTX_SERVER, IID_IUwbAnalyzer, (LPVOID *)&m_poUwbAnalyzer );
m_poAnalyzerSink = new CAnalyzerSink();
// Make sure the COM object corresponding to pUnk implements IProvideClassInfo2 or
// IPersist*. Call this method to extract info about source type library if you
// specified only 2 parameters to IDispEventImpl
hr = AtlGetObjectSourceInterface(m_poUwbAnalyzer, &m_poAnalyzerSink->m_lFCid,
&m_poAnalyzerSink->m_iid, &m_poAnalyzerSink->m_wMajorVerNum,
&m_poAnalyzerSink->m_wMinorVerNum);
if ( FAILED(hr) )
return 1;
// connect the sink and source, m_poUwbAnalyzer is the source COM object
hr = m_poAnalyzerSink->DispEventAdvise(m_poUwbAnalyzer, &m_poAnalyzerSink->m_iid);
if ( FAILED(hr) )
return 1;
