As you know, ICS component use hidden window to receive notification messages from winsock and to use internal messages. By Windows design, messages are processed in the context of the thread having created the window. So if you create a component in the main thread context, all his messages will be handled by the main thread. If you create a component from a thread Execute method, all messages will be processed in that thread context. Side note: A thread constructor is executed in the context of the calling thread (usually the main thread) that's why you should not create the ICS component in TTHread.Create but in TThread.Execute. ICS component has a ThreadDetach and a ThreadAttach procedure. They simply destroy and recreate the hidden window. Contribute to the SSL Effort.

Re: [twsocket] Program to thread
Because the otherwise it would execute in the main thread context. Or you can use ThreadAttach which would be a waste of CPU cycles...

No problem i.e.: while GetMessage(Msg, 0, 0, 0) do begin if Msg.message = WM_USER + 1 then TWSocket(Msg.WParam).ThreadAttach else if Msg.message = WM_USER + 2 then begin TWSocket(Msg.WParam).ThreadDetach; Postmessage(Form1.Handle, WM_USER + 3, Msg.WParam, 0); end else begin TranslateMessage(Msg); DispatchMessage(Msg); end; end; > >> Think fully event-driven ;-) > It' the only I can ;-) > > > Paul -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] Program to thread
Thanks for the fast response. However, I need all the items listed, including the hidden window. In the OnRequestdone event, I sometimes need to restart the the same operation which I can't do from within the onRequestDone event. I just wanted to know if there was something else I should do Paul -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
