Hello Nick,

if you execute a component in thread context taht need a message pump
(like TWSocket) then you have to pump messages. TWSocket has this on
board, so that's the proposed method.

The message pump (you can write your own of course) I proposed will
break his loop if a WM_QUIT message arrive. So to stop the thread you
have to post a WM_QUIT message to the window.

Depending on the application you wants to do you eventually make your
own message queue or hidden window inside your thread and do what you
wants.

note that you dont need thread if intention is only to have a couple of
components. You normally only need thread if you have to execute a
lengthy process yoruself.
