How to solve the "Control.Invoke must be used to interact with controls created on a separated thread" Error Exception

Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
serverSocket.Bind(new IPEndPoint(IPAddress.Loopback, portNo));

Socket client = serverSocket.Accept(); 
MessageBox.Show("Client Connected"); 

//Sent to Client 
NetworkStream ns = new NetworkStream(client); 
StreamWriter writer = new StreamWriter(ns); 
writer.AutoFlush = true; 
writer.WriteLine(sb.ToString()); 

//Receive from Client NetworkStream 
Stream nets = new NetworkStream(client); 
StreamReader reader = new StreamReader(nets); 
string clientIPAddress = reader.ReadLine();

By doing what it says? It sounds like you're in some kind of callback, but (due to thread affinity) you can only talk to controls on their associated thread. So:

string newAnswer = LongComplexCode(); // on worker thread here
someControl.Invoke((MethodInvoker) delegate {
    /* your work here, e.g. */
    someControl.Text = newAnswer; // on UI thread here
});
