C#

I coding the soft connect client to server by thread and Tcp Socket. But in the loop while(true) the code is not run, it's just "Not Responding".
I use win7 (64 bit) and Net FrameWork 4

TcpListener serverListener;
        TcpClient client;
        ArrayList listClient = new ArrayList();


        private void btnStart_Click(object sender, EventArgs e)
        {
            label2.Text = "Started";
            serverListener = new TcpListener(System.Net.IPAddress.Any, 1000);
            serverListener.Start();
            
            while (true)
            {
                while (!serverListener.Pending())
                {
                    Thread.Sleep(1000);
                }
               
                //HandleClient handleClient = new HandleClient();
                //handleClient.start(client);                   
                new Thread(connecting).Start();
                
            }
            //client.Close();
            //serverListener.Stop();
        }
        public void connecting()
        {
            TcpClient clientConnecting = serverListener.AcceptTcpClient();
            byte[] bytesFrom = new byte[10025];
            string dataRecieved;
            while (true)
            {
                NetworkStream nkStream = clientConnecting.GetStream();
                nkStream.Read(bytesFrom, 0, (int)clientConnecting.ReceiveBufferSize);
                dataRecieved = System.Text.Encoding.ASCII.GetString(bytesFrom);
                dataRecieved = dataRecieved.Substring(0, dataRecieved.IndexOf("$"));
                txtMess.Text += dataRecieved + "   ";
            }
        }
