Socket-based client and server-side chat Bots

The service-side code is as follows:

Using System;
Using System.Net;
Using System.Net.Sockets;
Using System.Text;
Using System.Threading;
Using System.Windows.Forms;

Namespace Client
{
public partial class Form1:form
{
Public Form1 ()
{
InitializeComponent ();
To make a thread-safe call to a Windows forms control
Richtextbox.checkforillegalcrossthreadcalls = false;
}
Private Socket ServerSocket;
