Socket Help! Winsock was so much easier!

[LuvKnight]

I can create a connection, but I can't send nor receive data.

    Private tcpClient As tcpClient
    Private tcpListener As tcpListener

    Private Function DisplayText(ByVal TextToAdd As String)
        txtDisplay.AppendText(TextToAdd + vbCrLf)
    End Function

    Private Sub txtInput_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtInput.KeyUp
        If e.KeyCode = Keys.Enter And txtInput.Text <> "" Then
            DisplayText(txtInput.Text)
            txtInput.Text = ""
        End If
    End Sub

    Private Sub btnConnect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnConnect.Click
        Me.Text = "Client"
        Try
            tcpClient = New TcpClient()
            tcpClient.Connect("127.0.0.1", 1337)

            DisplayText("Connection established")
        Catch ex As Exception
            DisplayText(ex.ToString)
        End Try
    End Sub

    Dim message As String = "wahahahaha"

    Private Sub btnListen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnListen.Click
        Me.Text = "Server"
        Try
            DisplayText("Waiting for connection...")

            tcpListener = New TcpListener(System.Net.IPAddress.Parse("127.0.0.1"), 1337)
            tcpListener.Start()

            Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient()

            DisplayText("Connection established")
        Catch ex As Exception
            DisplayText(ex.ToString)
        End Try
    End Sub

Deadline for the project is 2 days time and I yet to finish it, anyone to the rescue? Need a application than can act as a client AND a server which a click of a button. Using .NET sockets.

Late to the party, guess your deadline passed by now, but...

I don't see anywhere in your code where you try to send data. Maybe do a tcpClient.Send.

Check the built in help for basic working examples.

I'm trying to write a Windows Service that connects to one server and multiple clients connect to it. Haven't got it down yet, but the starting code was taken from the help. This app was written and works fine in VB6, trying to port to .NET service. I agree that it was easier (faster) with the Winsock control. Gives me something to do, anyway.
