Detect Socket Client Disconnect

3
Hi,

I'm having trouble detecting the client machine connection lost when the client physically pushes the power or restart button on their computer.

Using the code from Plater in the following thread: http://bytes.com/topic/net/answers/8...-socket-closed

I have managed to detect disconnect by the client when the client window form is closed, but if the client computer switches off or powers off, it doesn't detect a disconnect =(

What is the best way to detect this?

Hmm, I don't think I was aware that power loss didn't trigger the same way as a close.
Well, the old way was to try to do a read/write on the socket and see if it comes back with a timeout or an errorcode.

I don't really have a good way to test on power loss so I cannot poke around for ways it could happen
