So you build your combobox, wait 10 seconds, one client disconnects, all
the clients numbers reduce by one and your combobox is out of date. When
you try to send a command to one of them it may be the wrong client or
you'll get an exception because there are fewer clients.
I didn't think of this :(
That's why you need a server socket listening at each client computer.
Every time the a client computer starts, connect to the Server computer
and introduce himself. Hey, my name is "Earl" and I'm listening to your
commands at this "Address". I will report to you any errors occurring here.
With this introduction message you can now add one more Client computer
to your "Combobox" of the Server Application. Now you have a Client
that, even if disconnected, you know is listening at that "Address" for
any command the Server wish to send.
