Sockets that won't stop

I've created a very simple tcp\ip program using your basic send and recv
socket functions for WM 2003 SE. The sockets are set for blocking which is
fine, since they have their own thread, however if I loose connection the
socket just hangs forever. Is there a setting I can change that will stop
this(allow the socket to time out)?

I know I can create a non blocking socket to get around this, but this
solution seems more complex then its needs to be. Any suggestions?

Hi,

If you want to use a blocking read, then you might want to do it like this:

If

Client.GetStream.DataAvailable = True Then

Try

Client.GetStream.Read(Buffer, 0, READ_BUFFER_SIZE)

RaiseEvent DataAvailable(Buffer) 'or whatever

Catch ex As Exception

End Try

End If
