Of course, never call sleep() (at least in 99.99% of the casses) since it pauses the calling thread. > I know how to get HTML with Async via Events but i have no idea how > program it so that Main UI thread > will wait and then continue.. :) Simply use THttpCli's synchronous methods such as Get rather than GetAsync. -- Arno -- 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

Either use the events or, if available, the synchronous methods. -- Arno -- 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

The HTML fetches your stuff async and stores it somewhere and sets some "get was successfull" flag. Timer runs with say 50ms and checks that flag until either it's signalling ok or a timeout has elapsed. For the timeout you can fetch system time at the point where you start the timer and compare with current time in your OnTimer. On timeout present a nice error message or so... That's a basic but workable sheme for this. For more complex things it can be extended into a state machine.
