Client / Server & UDP

Hi,

I am trying to write a simple Client/ Server application. I am using a TcpListener, and a TcpClient with a NetworkStream. I have got as far as connecting a single client to a server app, and my server can read data sent from the client. However, I want my server to send something back to acknowledge the connection - I am confused. Do I need a separate UDP connection or is the fact that a connection has already been established enough? At the client end I am creating a socket to send the data to the server - it keeps on falling over when I try to create a listener socket at the client end waiting for a response.

Can somebody point me to a simple echo style application or something that will help me?

I would be most grateful,

Thanks,
DJ

i didnt understand quite all ur question but i am facing a problem in my client/server tcp application..when the server sends data to the client it disconnects.. anyone knows why? :confused: was that what u mean?

When you accept the connection on the server, you can do it like so...

Code:

---

TcpClient talkBack = myTcpListener.AcceptTcpClient();

---

now you have a new TcpClient which can send data from the server to your client the same way your client does. Good luck!

didnt anyone experience what happened to me? if no maybe its the class i used its stupid..could u share it with me?

tks..
