Visual Basic TCPControl Help - I've Searched, Looked and Learn But not exactly getting it right - Please Help

Question

Simple Card Game - that works
Now want to give it Multiplayer Functinality
Also I am confused, how do I get the client to get information sent from my server to it, since it is not listening (and store it into a string)
I really just want a bare bones code to
have A Master Server that Can recieve Multiple Connections
That Master Server Needs to be able to get messages from each user connected to it
The Master Server Needs to be able to send Messages to each user connected to it
each user (client) needs to be able to recieve and show messages recieved from the master server!
That really sums it up - I need to stream line the network code.  I need to focus on the actual card game itself!
Please Help!!!!
1 - Player will start their game (client)
2 - The client will connect to the server
3 - Master Server Accepts the Connect
4 - The Client will automatically send their login info as a string to the Master Server
5 - Master Server Will check the string and get user info - if the Info is correct then the Master Server will send a message to the Client as a string letting it know it is connected
6 - Master Server Will give that player a UniqueID
7 - Master Server Will put Player in a list as An Available Player
8 - 
9 - Now
10 - 
11 - Player 2 will start their game (client)
12 - The client will connect to the server
13 - Master Server Accepts the Connect
14 - The Client will automatically send their login info as a string to the Master Server
15 - Master Server Will check the string and get user info - if the Info is correct then the Master Server will send a message to the Client as a string letting it know it is connected
16 - Master Server Will give that player a UniqueID
17 - Master Server Will put Player2 in a list as An Available Player
18 - 
19 - Now since there are 2 players
20 - 
21 - The 2 players are removed from the Available Player List
22 - 
23 - Master Server will randomly pick a player 1 to go first
24 - Master Server Sends Message to Player to take turn (as a string code)
25 - Player 1 plays a card - the card info is sent as a string to the master server
26 - The Master Server then sends the Player 1 info to Player 2
27 - Player 2 Client gets the info from the master server that contains the card info from player 1
28 - Player 2 plays their card and the information is sent to the master Server
29 - 
30 - Until
31 - 
32 - One of the players is considered a winner
33 - At that Time the Server will Record Player 1 as winner or loser and Player 2 as winner or looser  
34 - Now The 2 Players are put back onto the available players list
Now this is where I am stuck.
Step 11 - 
How do I get my progam to accept more than one person?
So my problem is my TCPControl I guess  SO code below
ClientTCPControl.vb (Class)
Imports System.IO
Imports System.Net
Imports System.Net.Sockets
Imports System.Threading
Imports System.Text.RegularExpressions
Public Class ClientTCPControl
    Public Client As TcpClient
    Public DataStream As StreamWriter
    Public Sub New(Host As String, Port As Integer)
        'Client
        Client = New TcpClient(Host, Port)
        DataStream = New StreamWriter(Client.GetStream)
    End Sub
    Public Sub Send(Data As String)
        DataStream.Write(Data & vbCrLf)
        DataStream.Flush()
    End Sub
End Class
MasterSercerTCPControl.vb
Imports System.IO
Imports System.Net
Imports System.Net.Sockets
Imports System.Threading
Imports System.Text.RegularExpressions
Public Class MasterServerTCPControl
    Public Event MessageReceived(sender As MasterServerTCPControl, Data As String)
    Public PublicServerIP As IPAddress = IPAddress.Parse("10.0.0.6")
    Public ServerPort As Integer = 64554
    Public Server As TcpListener
    Private ComThread As Thread
    Public IsListening As Boolean = True
    'CLIENTS
    Private Client As TcpClient
    Private ClientData As StreamReader
    Public Sub New()
        Server = New TcpListener(PublicServerIP, ServerPort)
        Server.Start()
        ComThread = New Thread(New ThreadStart(AddressOf Listening))
        ComThread.Start()
    End Sub
    Private Sub Listening()
        'Create Listener Loop
        Do Until IsListening = False
            'Accept Incoming Connections
            If Server.Pending = True Then
                Client = Server.AcceptTcpClient
                ClientData = New StreamReader(Client.GetStream)
            End If
            'Raise event for incoming messages
            Try
                RaiseEvent MessageReceived(Me, ClientData.ReadLine)
            Catch ex As Exception
            End Try
            'Reduce CPU Usage
            Thread.Sleep(100)
        Loop
    End Sub
End Class
Client Code This Sub Runs when the Player Clicks the Connect Button
    Private Sub cmdConnect_Click(sender As Object, e As EventArgs) Handles cmdConnect.Click
        'Make Connection to Master Server
        Client = New ClientTCPControl("10.0.0.6", 64555)
        If Client.Client.Connected Then cmdConnect.Text = "Connected"
        varConnectedToServer = True
        'Create Login Credential String
        LoginCredentials = "login" & "," & varUserName & "," & varUserEMail & "," & varUserPassword & "," & varUserState & "," & varUserMachineIP
& "," & varUserInternetIP & "," & varPlayerPort & ","
        SendLoginCredentialsMessage()
    End Sub
Also I am confused, how do I get the client to get information sent from my server to it, since it is not listening (and store it into a string)

Answer 1

I suggest you search the net until you find something that sounds like it may be able to do what you want to do.
Like this link from CodeProject
C# \ VB .NET Multi-user Communication Library (TCP).
Although for the server to work I suppose it will need to be on a machine which has a public internet IP address or perhaps port forwarding would need to be used or dynamic dns. Things which may cost extra or not be available from your ISP.
