Problem with Threading and treeView.

Question

Hello everyone! ok so I have the following problem: (look at the buttom for error message) (check for comments to find whats wrong) private void connect() { try { socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPAddress ip = Dns.Resolve("irc.quakenet.org").AddressList[0]; socket.Connect(new IPEndPoint(ip, 6667)); //The problem lays here.//////////////////// //////////////////////////////////////////// this.treeView1.Nodes.Add("Server"); //////////////////////////////////////////// //////////////////////////////////////////// if(socket.Connected) { send("NICK " + strNick1); send("USER " + strNick1 + " 8 " + " * " + ":" + strFirst + " " + strLast); recive(); } else this.richTextBox1.Text += "Could not connect to server"; } catch(Exception ex) { this.richTextBox1.Text += ex.Message + "\n"; } } connection() runs from the following lines of code: Thread thread1 = new Thread(new ThreadStart(connect)); thread1.Start(); The error message says the following: The action being performed on this control is being called from the wrong thread. You must marshal to the correct thread using Control.Invoke or Control.BeginInvoke to perform this action. I´ve never used Control.Invoke etc before so I would realy appreciate if anyone could help me get this thing working.
