Question

This seems pretty basic, but I couldn’t find on the web how to do this.

I have the following code:

public static void StartChatWithUser(Microsoft.Lync.Model.Contact imContact, string title = null)
{
    try
    {
        var lyncClient = Microsoft.Lync.Model.LyncClient.GetClient();

        var conversation = lyncClient.ConversationManager.AddConversation();
        conversation.AddParticipant(imContact);
        if (!string.IsNullOrEmpty(title))
        {
            conversation.Properties[Microsoft.Lync.Model.Conversation.ConversationProperty.Subject] = title;
        }
        var im = conversation.Modalities[Microsoft.Lync.Model.Conversation.ModalityTypes.InstantMessage];
        if (im.CanInvoke(Microsoft.Lync.Model.Conversation.ModalityAction.Connect))
        {
            im.BeginConnect((ar) => { if (ar.IsCompleted) { ((Microsoft.Lync.Model.Conversation.InstantMessageModality)ar.AsyncState).EndConnect(ar); } }, im);
        }
    }
    catch( Exception x )
    {
        //Handle exception
    }
}

This “sort-of” works, since it opens the contact window and starts a chat – meaning the other side is requested to join the chat.

Is there a way for me to open the Conversation Window without initiating the chat with the other user (I want it the same way as when I double click a user in the Lync contact list).

posted the same question at the Lync Client Dev. TechNet forum: http://lksz.me/s8Yn8a.

Thanks in advance.

My final result

Thanks to the answer provided by MOHAMED A. SAKAR and ckeller, I fixed my code, and here is my new method.
Thanks guys

The following using clause is needed:

using Microsoft.Lync.Model.Extensibility;

And here is the new code:

public static void StartChatWithUser(Microsoft.Lync.Model.Contact imContact, string title = null)
{
    try
    {
        var lyncAutomation = Microsoft.Lync.Model.LyncClient.GetAutomation();

        var inviteeList = new string[] { imContact.Uri };
        var modalitySettings = new Dictionary<AutomationModalitySettings, object>();
        modalitySettings.Add(AutomationModalitySettings.SendFirstInstantMessageImmediately, false);
        if (string.IsNullOrEmpty(title))
        {
            modalitySettings.Add(AutomationModalitySettings.Subject, title);
        }

        lyncAutomation.BeginStartConversation(
            AutomationModalities.InstantMessage,
            inviteeList,
            modalitySettings,
            (ar) => { if (ar.IsCompleted) { ((Automation)ar.AsyncState).EndStartConversation(ar); }},
            lyncAutomation);
    }
    catch( Exception x )
    {
        //Handle exception
    }
}

Answer 1

you should first create Dictionary of AutomationModalitySettings and their values:

private Dictionary<AutomationModalitySettings, object> _modalitySettings;

After that you should initiate these modalities:

_modalitySettings = new Dictionary<AutomationModalitySettings, object>();
_modalitySettings.Add(AutomationModalitySettings.SendFirstInstantMessageImmediately, false);

after that you could initiate the call

_asyncResult = _automation.BeginStartConversation(
             _chosenMode,
             _inviteeList,
             _modalitySettings,
             null,
             null);

I hope this helps you
