Network Socket Blocking

Hi all,

I've written a program which distributes binary data to a number of clients
via TCP. The program runs perfectly unless one of the client programs hangs
and then it freezes while waiting for the socket.send(Data) method to
complete.

I've tried all of these socket options to overcome this event:

'Set send timeout to 2 seconds:
_Client.SetSocketOption(SocketOptionLevel.Socket,
SocketOptionName.SendTimeout, 2000)
'Stop the socket from blocking:
_Client.Blocking = False
'Don't allow network delays:
_Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.NoDelay,
1)

But it still hangs when one of the client programs enters a bad state.

Is there any way to determine when a client socket connection has entered a
bad state and then stop trying to send the data?

Any suggestions would be greatly appreciated.

-Duncan
