VB.NET Chat Server Program

Multithreaded Socket Programming is the basic idea behind a TCP Chat Server communication. In the previous section Multithreaded Socket Programming we can see a Multithreaded Server Socket Program communicate 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 Clients send messages to Server and the Server broadcast the message to all Clients currently connected to the Chat Server . From the following diagram you can see how a VB.NET TCP Chat Server is handling communication between Client to Client.
