Namespace: Microsoft.Office.Interop.UccApi
Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)

Syntax

'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);
    }
}
