Hello

I have been trying to make a socket listener, but it seems as if I am missing something
Here is my code:

Dim listener As Socket

Dim socketed As Socket

listener = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) 'makes a server

listener.Bind(New Net.IPEndPoint(Net.Dns.Resolve("192.168.1.44").AddressList(0), 8889))

Dim RecvBytes(256) As Byte

Dim finish As Boolean

listener.Listen(4)

While True

socketed = listener.Accept()

Dim bytes As Int32 = socketed.Receive(RecvBytes, RecvBytes.Length, 0)

Dim msg As String

msg = System.Text.ASCIIEncoding.ASCII.GetString(RecvBytes, 0, bytes)

MsgBox(msg)

Exit While

End While

I know that some of the code do not make any sence(e.g. exit while), but I have been testing. My problem is the line where I Binds. I want to listen on a special port. I get the error that "The requested address is not valid in its context". I presume that it is the Net.Dns.Resolve("192.168.1.44") but I have no idea what else to write. If I change 192.168.1.44 to Localhost, no errors occour. How can I skip this argument? I do not need it at all since I only want to listen on a special port - not giving a damn who is connecting.

Thanks in advance for any suggestions

Lasse

go to http://www.planet-source-code.com <http://www.planet-source-code.com>

and look under the dot net category and do a find on socket
there is a nice easy class for you to work with there.
