Below is the full chat code which i am using it is blocking . I think the textBox1_KeyDown event handler is blocking ..

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
try
{
if (e.KeyCode == Keys.Enter)
{
writer.Write(Form1.GetSysName() + " : " + input_text.Text); // Send to Sever

output_text.Text += "\r\n" + Form1.GetSysName() + " : " + input_text.Text;

input_text.Clear();


}
}
catch (SocketException se)
{
output_text.Text += "\n Error waiting Object";
}
}


public void Run_client()
{

try
{
//output_text.Text += "Attempting to Connecting to the server\n";

// Step 1: Create TCPClient and connect to the Server
client = new TcpClient();
string var4 = ipaddress2;
client.Connect(var4, 5000); // 5000 is the port number that the Sever is listening on it

// Step 2: Get NetworkStream Associated With TcpClient
output_stream = client.GetStream();

// Step 3: Create Object for Writing and Reading Across Stream( NetworkStream)
writer = new BinaryWriter(output_stream);



reader = new BinaryReader(output_stream);
// output_text.Text += "\r\nGot IO Stream \r\n";
input_text.ReadOnly = false;

do
{
//Step 3:
try
{
//Reading the message form Server

message = reader.ReadString();

output_text.Text += "\r\n : " + message;

}
catch (Exception e)
{
//System.Environment.Exit(System.Environment.ExitCode);
}
}while (message != "Server>>terminate");


// Step 4: Closing Connection
writer.Close();
reader.Close();
output_stream.Close();
client.Close();
}
catch (SocketException se)
{
MessageBox.Show(se.Message);
}

}

I want to start a thread for the text_Box_Event , because my this text box event is continuosly being used until program is closed , so this text_box_event blocks the UI . Thats why i want to make a thread and attach a event with a thread....
