remember sockets are unmanaged resources!

Speaking as someone who much prefers C# to VB.NET, I don't actually
agree. I'm not aware of anything C# can do that makes it more able to
implement a multithreaded listener than VB.NET - the sam
king fine but I need to add in some client address validation so
the clients can't populate each others data.
Thanks

This is one way of doing it - change it as needed for your situation. You'll
want to break this up into separate functions, threads, etc.

The quick and dirty solution to this might be to make a subclass of
tcpclient that doesn't have its socket property marked Protected, thus:
Class ExposedSocketTcpClient
Inherits TcpClient

Thanks, that helps a lot.
My biggest problem is probably the MS example I chose to build from.
- passing nothing in the state parameter
- I was inside a class called 'client', making it a bit tough to get the
TCPClient.client (socket)
So, I think I've sorted that out with
'class UserConnection, th
OK, you're now showing us a different bit of code from before. The
first snippet was calling EndConnect, so you want to find the
corresponding call to BeginConnect. (That's why I asked what you were
passing to BeginConnect in my previous post.) However, you've got the
same problem in the code exam
Socket = CType(ar.AsyncState, Socket)
Dim ClientSocket As Socket = client.???
Dim ClientIPAddress as string =ClientSocket .RemoteEndPoint.ToString())

At the risk of going for the obvious question, are you actually passing
in the socket as the 'state' parameter when you call BeginConnect? If
'client' is null in this situation, that implies that ar.AsyncState was
also null, which implies that you passed in null as the 'state'
parameter when you c

client=Nothing in the first place.
Thanks for any suggestions

Hi All,
In a sub much like this one, from "Using an Asynchronous Client Socket
[Visual Basic]", I keep getting an exception rather than a socket.
Is there a problem getting the socket using this technique?
