tcp/ip socket

[Harikrk]

i am working on a project to communicate with clinets using tcp/ip protocol. I have a server system where this program is being done. I have clinets which are connnected to my ip. These clients are capable of accepting commands from the server and gove reply for that. For eg:- if i give %Name to clinet it will send back the system ip address. private void button1_Click(object sender, EventArgs e) { Listener = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp); IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any,5005); Listener.Bind(ipLocal); Listener.BeginAccept(new AsyncCallback(OnClientConnect), null); } private void OnClientConnect(IAsyncResult asyn) { Client = Listener.EndAccept(asyn); WaitForData(); } private void WaitForData() { Client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(OnDataReceived), null); } private void OnDataReceived(IAsyncResult asyn) { Byte[] sendBytes = Encoding.UTF8.GetBytes("%Name"); string szData; int iRx = 0 ; iRx = Client.EndReceive(asyn); char[] chars = new char[iRx + 1]; System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder(); int charLen = d.GetChars(buffer, 0, iRx, chars, 0); szData = new string(chars); MessageBox.Show(szData.ToString()); Client.Send(sendBytes); WaitForData(); } The sending of data is working fine here. but when i revceive data they are all junk values even after converting to string. Junk vlaues means some single characters only Please let me know if tehre is someone extertise in this feild as i am new to this Thanks in advance Harikrishnan

I've used: string receivedText = System.Text.Encoding.ASCII.GetString(buffer, 0, buffer.Count)); Of course this assumes that "buffer" in your case is a byte array. Also, please be sure to check what the client is supposed to be sending. Is it an array of values that need interpreting? Or is it a human readable string? Phil
