Multithreaded Socket Programming is the basic idea behind a TCP Chat Server communication. A Multithreaded Server Socket Program communicates with more than one Client at the same time. But there the communication is happening only between Server to Client or Client to Server, there is no communication between Client to Client. In a Multithreaded Chat Server, a Client can communicate with any number of Clients, currently connected on the Chat Server.



Each Client sends messages to the Server and the Server broadcasts the message to all Clients that are currently connected to the Chat Server. From the following figure you can see how a VB.NET TCP Chat Server is handling communication between Client to Client.

How to run Chat Server program?

After creating the Chat Server and Chat Client programs we have to run the Server program first and then run the Client program. In the Client program enter a Chat name and click the “Connect to Server “button. Then you can see the message in the Server program User Joined Chat Room. Similarly you can connect more than one Client at the same time and start chatting each other. It is better to Compile and Build the program and run from the .exe files.

Yes, as @ Mansi said it's really helpful.
I have done the same functionality in a j2me using bluetooth for a group chat. Now I have to done it in VB.NET. Not a group chat, but a client server programming, but the idea is just the same

thank you very much @isaac

[English]
Good morning ... the question arises in the following, when I start the server and a client, write the name of it and connect, now when I close the client form returns me an error in the following line:

serverStream.Read(inStream, 0, buffSize)

I tried try ... catch ... closing connections, TCP client, but nothing. Any idea ¿?

Buenas... la duda surge en lo siguiente, cuando inicio el servidor, y un cliente, escribo el nombre del mismo y lo conecto, ahora cuando quiero cerrar el formulario del cliente me devuelve un error en la siguiente línea:

serverStream.Read(inStream, 0, buffSize)

Probé con try... catch... cerrando las conexiones, tcpclient, pero nada. Alguna Idea¿?
