Send Feedback

This interface retrieves information about an event of type RTCE_PRESENCE_STATUS. This type of event is used after a change in presence status.

Methods

The following tables show the methods for this interface in vtable order. This is the order in which the compiler calls the methods. This interface inherits the methods for the IUnknown and IDispatch interfaces.

The following table shows the IDispatch methods.

Method Description
GetIDsOfNames Maps a single member name and an optional set of parameter names to a corresponding set of integer dispatch identifiers (DISPIDs). These identifiers can then be used on subsequent calls to IDispatch::Invoke.
GetTypeInfo Retrieves the type information for an object.
GetTypeInfo Retrieves the number of type information interfaces provided by an object, either zero (0) or 1.
Invoke Provides access to properties and methods exposed by an object.

The following table shows the IRTCPresenceStatusEvent methods.

Method Description
StatusCode Gets the result code of the completed operation.
StatusText Gets the text message corresponding to the result code of the completed operation.
GetLocalPresenceInfo Retrieves information about the local presence.

Obtaining a Pointer

When the application's implementation of the IRTCEventNotification::Event method indicates an RTC_EVENT enumeration value of RTCE_PRESENCE_STATUS, the method's pEvent parameter is an IDispatch pointer for the IRTCPresenceStatusEvent interface.

Remarks

To enable reception of presence status events, the application must call the IRTCClient::EventFilter method and set an event filter mask that includes the RTCE_PRESENCE_STATUS event. If the application does not call IRTCClient::EventFilter, it will not receive any events.

Requirements

OS Versions: Windows CE .NET 4.2 and later.
Header: Rtccore.h, Rtccore.idl.
Link Library: Rtcdll.dll.
