ITParticipantEvent interface
[ITParticipantEvent is not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]
The ITParticipantEvent interface contains methods that retrieve the description of participant events. When the application's implementation of the ITTAPIEventNotification::Event method indicates a TAPI_EVENT equal to TE_PRIVATE, the method's pEvent parameter is an IDispatch pointer for the ITParticipantEvent interface. The methods of this interface can be used to retrieve information concerning a participant change that has occurred.
Note
You must call the ITTAPI::put_EventFilter method and set an event filter mask that includes the TE_PRIVATE event to enable reception of participant events. If you do not call ITTAPI::put_EventFilter, your application will not receive any events. For more information, see the Events overview.
Members
The ITParticipantEvent interface inherits from the IUnknown interface. ITParticipantEvent also has these types of members:
