For the past 3 days I've been working on the communication block of my application, though I've been struggling because of the port forwarding, which did not properly work, even using NATUPNPLib. Searching on the Internet about solutions for my problem I found out that applications like Skype, Messenger and Steam don't need port forwarding because they are the ones that connect to a server(don't listen to a port). So I decided to do something like this.
TCP Testing App code:
Am I on the right track?
If I make a proper application on the other end is this going to work?
TCP Testing App code:
Code:
Imports System.Net
Imports System.IO
Public Class Form1
Dim LocalHostaddress As String = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList(1).ToString()
Dim listener As Net.Sockets.TcpListener
Dim listenthread As Threading.Thread
Dim Reader As StreamReader
Dim Writer As StreamWriter
Dim IP As String = "1.1.1.1"
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
listener = New Net.Sockets.TcpListener(Net.IPAddress.Any, 10)
listener.Start()
listenthread = New Threading.Thread(AddressOf receive)
listenthread.IsBackground = True
listenthread.Start()
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
send()
End Sub
Private Sub receive()
Do
Dim ClientReader As New Sockets.TcpClient
ClientReader.Connect(IP, 10)
Reader = New StreamReader(ClientReader.GetStream)
MsgBox(Reader.ReadToEnd)
Loop
End Sub
Private Sub send()
Dim ClientWrite As New Sockets.TcpClient
ClientWrite.Connect(IP, 11)
Writer = New StreamWriter(ClientWrite.GetStream)
Writer.Write("something")
Writer.Close()
End Sub
End ClassIf I make a proper application on the other end is this going to work?
