All I'm looking for is a simple TCPClient/Listener ("hello world") example. I'm a newbie and Microsoft TCPClient/Listener class examples are not what I am looking for. All I am looking is for the TCPClient to send a message "Hello world" and for a TCPListener to get the message and to send a message back "I got your hello world message"?

A little help would be great. All I have is the TCPClient sending out "Hello World". Would this work? 

Dim port As Int32 = 13000
        Dim client As New TcpClient("192.168.0.XXX", port)
        ' Translate the passed message into ASCII and store it as a Byte array. 
        Dim data As [Byte]() = System.Text.Encoding.ASCII.GetBytes("Hello World")

    ' Get a client stream for reading and writing. 
    '  Stream stream = client.GetStream(); 
    Dim stream As NetworkStream = client.GetStream()

    ' Send the message to the connected TcpServer. 
    stream.Write(data, 0, data.Length)

    Yes..that should be fine for sending; assuming there is no actual protocol (most of the time there is). Receiving, however, is always more complicated than people think.

These two tutorials should show you how to do it with the bare minimum. The first one is more aimed at what you want I think.
