Socket Error

"The requested address is not valid in its context."

Code:

---

Try
    Dim ipAddress As IPAddress = IPAddress.Parse("192.168.0.4")
    Dim localEndPoint As New IPEndPoint(ipAddress, 1420)
 
    mySocket = New Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp)
 
    mySocket.Bind(localEndPoint)
 
    Dim szData As String = vbCr & vbLf
    Dim byData As Byte() = System.Text.Encoding.ASCII.GetBytes(szData)
 
    Dim sender1 As New IPEndPoint(IPAddress.Any, 0)
    Dim tmpRemote As EndPoint = DirectCast((sender1), EndPoint)
 
    mySocket.SendTo(byData, tmpRemote)
 
    recv = mySocket.ReceiveFrom(data, tmpRemote)
    TerminalTextBox.Text += "Message received from: " & tmpRemote.ToString()
    TerminalTextBox.Text += Encoding.ASCII.GetString(data, 0, recv)
 
    While True
        data = New Byte(1023) {}
        recv = mySocket.ReceiveFrom(data, tmpRemote)
        Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv))
 
    End While

Catch se As SocketException
    MessageBox.Show(se.Message)
End Try

Any ideas? :(

Is the UdpClient class better to use?

I get the same problem with my chat program if I don't type in my own IP or 127.0.0.1. Does anyone know??
