Re: TCP send get data

Like so many things in VB.NET compared to VB6, network communication is done in a far more object-oriented way. Instead of one "super class" that does everything, there are multiple classes that each have a well-defined purpose, obeying the "single responsibility principle". As a first option, consider using the TcpListener class to accept incoming connections, the TcpClient class to create the connection and the NetworkStream class to perform the actual communication. There's also the Socket class for more fine-grained control. You might like to follow the CodeBank link in my signature and check out my Asynchronous TCP demo, which shows the use of all three to asynchronously communicate between a server and multiple clients.

Look a bit more carefully. There is a link in my signature that lists my VB CodeBank threads. That list includes one on asynchronous TCP communication.

That asynchronous TCP thread is probably overkill for what you want. You should probably just use the corresponding synchronous methods, which are simpler. If you look around the web, you should be able to find plenty of examples of using the TcpListener and TcpClient classes.
