Hi everyone, I have a server-client chat application.The server program is running successfully but when the client press the button of disconnect,it doesn't display the line " you have left the session/chat room". Although it displays on Client window but i want to display this on server as well. Kindly giuide me how can i fix this problem. Best Regards.

Can anyone tell me about a converter that can convert a C# code (written using visual studio.net)to Perl script.. i have searched a lot on internet but couldn't find any information. kindly tell me if anyone knows about such converter. Regards

I can't. The code that you posted is a basic client/server example. I suggest you search for multiple chat-applications and study them.

okay!

I guess you can adapt it to send a message on every keystroke.

hey can yu guide me that how can i do this?? :(

You mean when you press "A", that the other side immediately receives that character and displays it?

yeah!!

Hi everyone! when i run the programs of server and client, they both run and also show the acknowledgement like >>Server Started! >>Client No:1 started! >>From client-1Message from Client >>Server to client<1>1 and so on for client 2, 3 ... but i want communication like if i type some text and then it display that text!!! I am using visual 2010... multithread Server program is

using System;
using System.Threading;
using System.Net.Sockets;
using System.Text;

namespace ConsoleApplication1

TcpListener serverSocket = new TcpListener(8888);
TcpClient clientSocket = default(TcpClient);
int counter = 0;

serverSocket.Start();
Console.WriteLine(" >> " + "Server Started");

counter = 0;
while (true)
{
counter += 1;
clientSocket = serverSocket.AcceptTcpClient();
Console.WriteLine(" >> " + "Client No:" + Convert.ToString(counter) + " started!");
handleClinet client = new handleClinet();
client.startClient(clientSocket, Convert.ToString(counter));
}

clientSocket.Close();
serverSocket.Stop();
Console.WriteLine(" >> " + "exit");
Console.ReadLine();
}
}

//Class to handle each client request separatly
public class handleClinet
{
TcpClient clientSocket;
string clNo;
public void startClient(TcpClient inClientSocket, string clineNo)
{
this.clientSocket = inClientSocket;
this.clNo = clineNo;
Thread ctThread = new Thread(doChat);
ctThread.Start();
}
private void doChat()

int requestCount = 0;
byte[] bytesFrom = new byte[10025];
string dataFromClient = null;
Byte[] sendBytes = null;
string serverResponse = null;

while ((true))

Console.WriteLine(" >> " + "From client-" + clNo + dataFromClient);

rCount = Convert.ToString(requestCount);
serverResponse = "Server to clinet(" + clNo + ") " + rCount;
sendBytes = Encoding.ASCII.GetBytes(serverResponse);
networkStream.Write(sendBytes, 0, sendBytes.Length);
networkStream.Flush();
Console.WriteLine(" >> " + serverResponse);

hello everyone, how can i send data to server?? I am using visual studio 2010.The program is working but i am not getting the option of " click here to send data to server" in the Form1 window that comes after client-server acknowledgment.Kindly guide me. client program is

using System;
using System.Windows.Forms;
using System.Net.Sockets;
using System.Text;

namespace WindowsApplication1
{
public partial class Form1 : Form
{
System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
NetworkStream serverStream;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1\_Load(object sender, EventArgs e)
    {
        msg("Client Started");
        clientSocket.Connect("127.0.0.1", 8888);
        label1.Text = "Client Socket Program - Server Connected ...";
    }

    private void button1\_Click(object sender, EventArgs e)
    {
        NetworkStream serverStream = clientSocket.GetStream();
        byte\[\] outStream = System.Text.Encoding.ASCII.GetBytes("Message from Client$");
        serverStream.Write(outStream, 0, outStream.Length);
        serverStream.Flush();

        byte\[\] inStream = new byte\[10025\];
        serverStream.Read(inStream, 0, (int)clientSocket.ReceiveBufferSize);
        string returndata = System.Text.Encoding.ASCII.GetString(inStream);
        msg("Data from Server : " + returndata);
    }

    public void msg(string mesg)
    {
        textBox1.Text = textBox1.Text + Environment.NewLine + " >> " + mesg;
    } 
}

}

the server program is

using System;
using System.Threading;
using System.Net.Sockets;
using System.Text;

namespace ConsoleApplication1
{

int counter = 0;

        serverSocket.Start();
        Console.WriteLine(" >> " + "Server Started"); 

        counter = 0;
        while (true)
        {
            counter += 1;
            clientSocket = serverSocket.AcceptTcpClient();
            Console.WriteLine(" >> " + "Client No:" + Convert.ToString(counter) + " started!");
            handleClinet client = new handleC

hi everyone, I have done single client-server application using c#. Now i have to made that application for multiple clients. kindly guide me. Regards

yeah you are right , it is AIX, someone told me wrong that it is IAX.. any ways thankyou :)

Hi Everyone Can anyone tell me about IAX scripting. what is it? and can it be used in the communication of client and server? I have done the client-server programming in C#.Both the programs are running individually but how can i communicate the client with server and vice verse.I mean how the connection between them is established?? Kindly guide me.!! Regards,
