'Declaration
ReadOnly Property ParticipantEndpoint As IUccSessionParticipantEndpoint
IUccSessionParticipantEndpoint ParticipantEndpoint { get; }
property IUccSessionParticipantEndpoint^ ParticipantEndpoint {
IUccSessionParticipantEndpoint^ get ();
}
/** @property */
IUccSessionParticipantEndpoint get_ParticipantEndpoint ()
function get ParticipantEndpoint () : IUccSessionParticipantEndpoint
Property Value
A value of the IUccSessionParticipantEndpoint** (IUccSessionParticipantEndpoint, for a .NET application) type. This returns the participant endpoint from which the IM message is sent.
Remarks
Win32 COM/C++ Syntax
HRESULT get_ParticipantEndpoint
(
IUccSessionParticipantEndpoint** ppSenderEndpoint
);
Note
In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API .
Example
The following example can be called from an OnInstantMessageReceived event handler, passing in an instance of IUccIncomingInstantMessageEvent. The example updates a client TextBox with both the User property of the sending participant and the message itself.
/// <summary>
/// Appends received text to the end of a text box, scrolls
/// the text box if necessary, and moves selection curser to bottom of box
/// </summary>
/// <param name="pIMEvent">UccIncomingInstantMessageEvent received in OnInstantMessageReceived</param>
/// <param name="pBoxToFill"></param>
/// <returns></returns>
private void ProcessIncomingIM(
UccIncomingInstantMessageEvent pIMEvent,
ref TextBox pBoxToFill)
{
if (pIMEvent.ContentType == "text/plain")
{
//append text box with Uri->User property of sending participant
pBoxToFill.AppendText(
pIMEvent.ParticipantEndpoint.Participant.Uri.User + ": ");
//append text box with message content
pBoxToFill.AppendText(pIMEvent.Content);
}
}
