How to: Send a meeting access key to a Persistent Chat room
Learn how to use Microsoft Lync 2013 SDK to start a Microsoft Lync 2013 meet-now audio conference. You can then send the meeting access key to a Persistent Chat room so that the room participants can join the conference by clicking a meeting URL in the chat room message or by calling an auto-attendant telephone number.
Applies to: Lync 2013 | Lync Server 2013
In this article |
Prerequisites
The prerequisites for sending a meeting access key are as follow:
Microsoft Lync 2013 must be installed and running on the development computer.
You must have sign-in credentials for Microsoft Lync Server 2013.
Microsoft Lync 2013 SDK must be installed on the development computer.
Start a new meet-now meeting
Use Lync 2013 API automation to start an audio conference that people can join from a telephone or a Lync 2013 client on a computer on either side of a corporate firewall.
To start the meeting
Call the static LyncClient.GetAutomation method to obtain the Microsoft.Lync.Model.Extensibility.Automation object.
Call the Automation.BeginMeetNow method to start the meet-now meeting.
In the callback method or lambda expression passed as the second argument in the previous method call, call the Automation.EndMeetNow method and cache the Microsoft.Lync.Model.Extensibility.ConversationWindow object that encapsulates the new meeting.
/// <summary> /// Starts a new meeting by using automation /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void StartMeeting_Button_Click_1(object sender, RoutedEventArgs e) { if (_Automation != null) { _Automation.BeginMeetNow((ar) => { _ConversationWindow = _Automation.EndMeetNow(ar); _Conversation = _ConversationWindow.Conversation; //Watch for changes in conference properties _Conversation.PropertyChanged += _Conversation_PropertyChanged; //Watch for participants added to meeting (Lobby) _Conversation.ParticipantAdded += _Conversation_ParticipantAdded; }, null); } }Get the Microsoft.Lync.Model.Conversation.Conversation object and register for the Conversation.PropertyChanged event so that you're notified when the access key property is available.
Post the meeting access key to a chat room
Now that you have the access key to the new audio conference, you can post the key to a Persistent Chat room as a room message. Other chat room users will be able to click the internal and external meeting URL strings or dial one of the auto-attendant telephone numbers and join the audio conference.
To get the access key
In the Conversation.PropertyChanged event callback method, read the ConversationPropertyChangedEventArgs.Property to get the conversation property that has changed.
If the changed property is the ConversationProperty.ConferenceAccessInformation property, continue this procedure.
Get the Microsoft.Lync.Model.Conversation.ConferenceAccessInformation object that encapsulates the access key.
The following example reads the event data value to get the conference access key.
ConferenceAccessInformation conferenceAccess = (ConferenceAccessInformation)e.Value;Read each property in the ConferenceAccessInformation object and form a string to be posted to the chat room.
The following example handles the PropertyChanged event on the conversation, gets all components of the access key, and stores them in a StringBuilder to be used when the user clicks the Post Access Key button in the UI.
/// <summary> /// Handles event raised when interesting conversation properties changed. /// Handler is only interested in conference properties /// </summary> /// <param name="sender"></param> /// <param name="e"></param> void _Conversation_PropertyChanged(object sender, ConversationPropertyChangedEventArgs e) { Conversation conference = (Conversation)sender; LoadTextBoxDelegate textBoxDelegate = new LoadTextBoxDelegate(LoadTextBox); switch (e.Property) { case ConversationProperty.ConferenceAccessInformation: try { _MeetingKey = new StringBuilder(); //These properties are used to invite people by creating an email (or text message, or IM) //and adding the dial in number, external Url, internal Url, and conference Id ConferenceAccessInformation conferenceAccess = (ConferenceAccessInformation)e.Value; _MeetingKey.Append("Meeting Id: " + conferenceAccess.Id); _MeetingKey.Append(System.Environment.NewLine); _MeetingKey.Append(conferenceAccess.AdmissionKey); _MeetingKey.Append(System.Environment.NewLine); string[] attendantNumbers = (string[])conferenceAccess.AutoAttendantNumbers; StringBuilder sb2 = new StringBuilder(); sb2.Append(System.Environment.NewLine); foreach (string aNumber in attendantNumbers) { sb2.Append("\t\t" + aNumber); sb2.Append(System.Environment.NewLine); } _MeetingKey.Append("Auto attendant numbers:" + sb2.ToString()); _MeetingKey.Append(System.Environment.NewLine); _MeetingKey.Append("External Url: " + conferenceAccess.ExternalUrl); _MeetingKey.Append(System.Environment.NewLine); _MeetingKey.Append("Inner Url: " + conferenceAccess.InternalUrl); _MeetingKey.Append(System.Environment.NewLine); this.Dispatcher.Invoke( new EnableDisableButtonDelegate(EnableDisableButton), new object[] { PostMeetingKey_Button, true }); this.Dispatcher.Invoke( textBoxDelegate, new object[] { ConferenceAccessInformation_block, _MeetingKey.ToString() }); } catch (LyncClientException lce) { System.Diagnostics.Debug.WriteLine("Exception on ConferenceAccessInformation changed " + lce.Message); } break; } }
To post the access key to a chat room
Get the Microsoft.Lync.Model.LyncClient as the entry point to the managed object model.
Verify that the user is following at least one chat room by reading the Count property of the RoomManager.FollowedRooms collection.
Get one of the followed rooms.
.gif "Tip")
TipThis example arbitrarily gets the first followed room but you should iterate on the room collection and look for a room whose title matches one that a user selects.
Send the access key to the selected chat room by calling the Room.BeginSendMessage method.
/// <summary> /// Posts the meeting access key to the first followed chat room in the local /// user's folled chat room collection /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void PostMeetingKey_Button_Click_1(object sender, RoutedEventArgs e) { try { //get the API entry point LyncClient lyncClient = LyncClient.GetClient(); //If the user has any followed rooms then get the first one if (lyncClient.RoomManager.FollowedRooms.Count > 0) { //get the first followed chat room Room myRoom = lyncClient.RoomManager.FollowedRooms[0]; //Create a dictionary to hold the MIME type of the chat room message and the //actual message text (the meet now access key) Dictionary<RoomMessageFormat, string> messageDictionary = new Dictionary<RoomMessageFormat, string>(); messageDictionary.Add(RoomMessageFormat.PlainText, _MeetingKey.ToString()); //Send the message to the chat room as a story myRoom.BeginSendStoryMessage( messageDictionary, "Meeting has started", (ar) => { try { myRoom.EndSendStoryMessage(ar); System.Diagnostics.Debug.WriteLine( "Succeeded on post story message to " + myRoom.Properties[RoomProperty.Title].ToString() ); } catch (LyncClientException lce) { System.Diagnostics.Debug.WriteLine( "Lync client exception on post story message to " + myRoom.Properties[RoomProperty.Title].ToString() + " " + lce.Message); } } , null); } } catch (ClientNotFoundException) { System.Diagnostics.Debug.WriteLine("Client is not running"); } catch (LyncClientException lce) { System.Diagnostics.Debug.WriteLine("Lync client exception on GetClient() " + lce.Message); } }
Code examples: Meet-now access manager
The meet-now access manager uses automation to start a new meet-now meeting with no participants. It launches a Lync 2013 conversation window, which requires that the Lync UI is not suppressed. After the meeting is started and the access key is shown in the middle text box, a user can click the Post Meeting Key button to post the key to the first followed Persistent Chat room.
Figure 1 shows the meet now access manager. This application starts new meet-now meetings and lets a user post the access key to a followed chat room, set the meeting access type, and let'sers in from the meeting lobby.
