Send Socket Call

[ccubed]

Imports System.Net.Sockets

Public Class Form1

Dim socket As New System.Net.Sockets.TcpClient
Dim send As Byte()

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

socket.Connect("66.226.73.112", 7705)
send = System.Text.Encoding.ASCII.GetBytes("\R\N")
socket.Client.Send(send)
Recv.Text += socket.Client.Receive(send).ToString & vbNewLine
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

send = System.Text.Encoding.ASCII.GetBytes(TxtToSend.Text & "\R\N")
socket.Client.Send(send)

End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Recv.Text += socket.Client.Receive(send).ToString & vbNewLine
End Sub
End Class


For some reason, it stops on the recv call and when I put a check for socket.client.available being greater than 0 it never gets anything. So the problem is that i'm not receiving any data. Is there any reason why?

First problem is that you are blocking inside of your Form_Load......

Public Class Form1

Dim socket As New System.Net.Sockets.TcpClient
Dim send As Byte()

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

socket.Connect("66.226.73.112", 7705)

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

send = System.Text.Encoding.ASCII.GetBytes(TxtToSend.Text & "\R\N")
socket.Client.Send(send)

End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
While socket.Client.Available <> 0
Recv.Text += socket.Client.Receive(send).ToString & vbNewLine
End While
End Sub
End Class


I modified it in this way. However, now socket.client.available is never greater than 0. I know that the host and port should send something because telnet gets something.

Why are you using a timer....use the proper events of the Socket class!!!!
