OK - that would do it thanks to none-blocking sockets and the new wait-functions (MsgWaitForMultpleObjects), but sounds more complicated to me than simply using the async methods. But as you already mentioned before, it's sure a question of programming and personal taste. When I started with ICS I also began to think event-driven which took me a while until I fully adapted the principle, but today I love it. The event-concept helps me also to avoid writing never ending spagetti-code :) > and so a sync FTP download does not stop the time running other things > at the same time, provided any 'waits' are calling ProcessMessages to > keep things moving (and there are no sleeps).
