So to use the component in asynchronous mode you must only use one thread? Is there any other benefit in using TDataModule apart from being able to see the components? I thought TDataModule could receive windows messages but I was sadly disappointed.

Depends. Basically it would be executed as part of a single thread, the main or another one because communication do to use a lot of CPU and a single thread is usually able to handle a lot of simultaneous connections. > I.e.

A TDataModule is just a container which is handly to use within the IDE for visual programming. But of course you may do exactly the same with a simple TObject derived class. > I assume to use a TDataModule to do this you would have to keep track of > the current > state/step/status/... so the code could respond appropriately to any > events and advance/abort/... the process? Yes indeed. If you look at many of the high level components in ICS, you'll see that they conatin a finite state machine. Even TWSocket itself has a state machine. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
