Subject: autoconnect with matrix
Hello,

I would like to connect a user automatically when the application started but I have a exception "System.UnauthorizedAccessException: Invalid cross-thread access error"

I use silverlight client sample.

Roster.xaml.cs

public Roster(XmppClient client)
        {
            InitializeComponent();

            _xmppClient = client;
            _presManager = new PresenceManager(_xmppClient);

            _xmppClient.OnRosterStart += new EventHandler<Matrix.EventArgs>(_xmppClient_OnRosterStart);
            _xmppClient.OnRosterItem += new EventHandler<RosterEventArgs>(_xmppClient_OnRosterItem);
            _xmppClient.OnRosterEnd += new EventHandler<Matrix.EventArgs>(_xmppClient_OnRosterEnd);
            _xmppClient.OnClose += new EventHandler<Matrix.EventArgs>(_xmppClient_OnClose);
            _xmppClient.OnMessage += new EventHandler<MessageEventArgs>(_xmppClient_OnMessage);
            _xmppClient.OnAuthError += new EventHandler<Matrix.Xmpp.Sasl.SaslEventArgs>(_xmppClient_OnAuthError);

            _xmppClient.OnLogin += new EventHandler<Matrix.EventArgs>(_xmppClient_OnLogin);
            _xmppClient.OnError +=new EventHandler<ExceptionEventArgs>(_xmppClient_OnError);
            _presManager.OnAvailablePresence += new EventHandler<PresenceEventArgs>(presManager_OnAvailablePresence);
            _presManager.OnUnavailablePresence += new EventHandler<PresenceEventArgs>(presManager_OnUnavailablePresence);
       
            [color=crimson]Connect();[/color]
           
        }
private void Connect()
        {
            /* TEST AUTOCONNECT */

            login.txtJid.Text = "MyUser";
            login.txtPassword.Password = "MyPass";
            
            _xmppClient.Username = login.Jid.User;
            _xmppClient.Password = login.Password;
         
            _xmppClient.XmppDomain = login.Jid.Server;
           
            _xmppClient.Port = 4502;

            _xmppClient.AutoPresence = false;
            _xmppClient.Priority = 10;
           
            // status and show for Autopresence after login
            _xmppClient.Status  = "online";
            _xmppClient.Show    = Matrix.Xmpp.Show.NONE;

            _xmppClient.Open();
        }

Thanks.

try to set a Dispatcher before you connect.

for thread safety all events from MatriX must be invoked.
If you set the Dispatcher property to your UI then MatriX does this automatically for you. Otherwise you have to invoke all events on your own.
Normally MatriX does find your UI and the Dispatcher automatically, but this does not work in your case, because you connect before the UI is completely initialized. So set a Dispatcher manual, or connect after the Ui is fully initialized.

Thank you very much !

I set a dispatcher manual.

public Roster(XmppClient client)
        {
            InitializeComponent();

            //ShowLogin();

            _xmppClient = client;
            _presManager = new PresenceManager(_xmppClient);

            _xmppClient.OnRosterStart += new EventHandler<Matrix.EventArgs>(_xmppClient_OnRosterStart);
            _xmppClient.OnRosterItem += new EventHandler<RosterEventArgs>(_xmppClient_OnRosterItem);
            _xmppClient.OnRosterEnd += new EventHandler<Matrix.EventArgs>(_xmppClient_OnRosterEnd);
            _xmppClient.OnClose += new EventHandler<Matrix.EventArgs>(_xmppClient_OnClose);
            _xmppClient.OnMessage += new EventHandler<MessageEventArgs>(_xmppClient_OnMessage);
            _xmppClient.OnAuthError += new EventHandler<Matrix.Xmpp.Sasl.SaslEventArgs>(_xmppClient_OnAuthError);

            _xmppClient.OnLogin += new EventHandler<Matrix.EventArgs>(_xmppClient_OnLogin);
            _xmppClient.OnError +=new EventHandler<ExceptionEventArgs>(_xmppClient_OnError);
            _presManager.OnAvailablePresence += new EventHandler<PresenceEventArgs>(presManager_OnAvailablePresence);
            _presManager.OnUnavailablePresence += new EventHandler<PresenceEventArgs>(presManager_OnUnavailablePresence);


             _xmppClient.Dispatcher = this.Dispatcher;
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<Matrix.EventArgs>(_xmppClient_OnRosterStart));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<RosterEventArgs>(_xmppClient_OnRosterItem));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<Matrix.EventArgs>(_xmppClient_OnRosterEnd));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<Matrix.EventArgs>(_xmppClient_OnClose));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<MessageEventArgs>(_xmppClient_OnMessage));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<Matrix.EventArgs>(_xmppClient_OnLogin));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<ExceptionEventArgs>(_xmppClient_OnError));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<PresenceEventArgs>(presManager_OnAvailablePresence));
             _xmppClient.Dispatcher.BeginInvoke(new EventHandler<PresenceEventArgs>(presManager_OnUnavailablePresence));
             Connect();
        }

and it's ok !

thanks

adding the Dispatcher should be enough. Then MatriX does all the invoke magic for you.
