| Platform SDK: TAPI |
The ITDigitGenerationEvent interface contains methods that describe digit generation events. When the application's implementation of the ITTAPIEventNotification::Event method indicates a TAPI_EVENT equal to TE_GENERATEEVENT, the method's pEvent parameter is an IDispatch pointer for the ITDigitGenerationEvent interface. The methods of this interface can be used to report on calls that require the generation of DTMF digits. This interface is implemented by the application and called by the TAPI 3.0 DLL.
Note You must call the ITTAPI::put_EventFilter method and set an event filter mask that includes the TE_GENERATEEVENT event to enable reception of digit generation events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events. For more information, see the Events overview.
