Eventi specifici del telefono e dell'indirizzo del dispositivo

L'esempio di codice seguente illustra un gestore eventi per gli eventi di indirizzo e dispositivo telefonico. Il codice per ogni evento mostra come creare l'interfaccia evento e come recuperare i dati dell'evento.

HRESULT STDMETHODCALLTYPE CMyEventNotification::Event(
   TAPI_EVENT TapiEvent,
   IDispatch * pEvent
)
{
    HRESULT hr = S_OK;
    //...
    switch (TapiEvent) 
    {
        case TE_ADDRESSDEVSPECIFIC:
        {
            ITAddressDeviceSpecificEvent* pITADSEvent = NULL;

            hr = pEvent->QueryInterface( 
                               IID_ITAddressDeviceSpecificEvent,
                               (void **)(&pITADSEvent) );
            // If (hr != S_OK) process the error here...

            // Retrieve data received from the TSP.
            long lParam1=0;
            hr = pITADSEvent->get_lParam1(&lParam1);
            // If (hr != S_OK) process the error here...

            long lParam2=0;
            hr = pITADSEvent->get_lParam2(&lParam2);
            // If (hr != S_OK) process the error here...

            long lParam3=0; 
            hr = pITADSEvent->get_lParam3(&lParam3);
            // If (hr !=S_OK) process the error here...

            // Process the data here.
            // ...
            pITADSEvent->Release();
            break;
        }

        case TE_PHONEDEVSPECIFIC:
        {
            ITPhoneDeviceSpecificEvent* pITPhEvent = NULL;
