Thanks for this tutorial. I’m gonna get around to remastering MSN somewhere soon with this.
I recognize that voice. 😀 Didn’t know you had a new channel.
Why TCPControl is not found by Visual Studio Community ?
thank you Sir it Help me more real time projects
You the man! This is pretty good man!
does it have a database?
How can I display the client IP address on the server side using VB.net
I got an error at the part when we were making the TCPcontrol class the error was on line 24 and it was the text : Server.Start in the public sub new , the error was : System.ArgumentOutOfRangeException: ‘Specified argument was out of the range of valid values.’
: Anyone know the fix to it ?
Here is my code :
Imports System.IO
Imports System.Net
Imports System.Net.Sockets
Imports System.Threading
Public Class TCPcontrol
Public Event MessageReceived(sender As TCPcontrol, Data As String)
‘ SERVER CONFIG
Public ServerIP As IPAddress = IPAddress.Parse(“192.168.0.1”)
Public ServerPort As Integer = 110992
Public Server As TcpListener
Private CommThread As Thread
Public IsListening As Boolean = True
‘ CLIENTS
Private Client As TcpClient
Private ClientData As StreamReader
Public Sub New()
Server = New TcpListener(ServerIP, ServerPort)
Server.Start()
CommThread = New Thread(New ThreadStart(AddressOf Listening))
CommThread.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
‘ REDUCE CPU USAGE
Thread.Sleep(100)
Loop
End Sub
End Class
aparently TCPControl is not a thing for me, help?
error in the (server.start () ) why ??

Is there a chance you create a tutorial for hosting for multiple clients with using port forwarding of your router? 🙂
