Hello Veit, Connect as whell as other methods can raise exceptions in case of failure. This because there has to be something prepare to connect in this case.
Then the real connection happens in background and you dont have to worry for exceptions. If there are they are internally handled. If connect fails then OnSessionConnected will fire with a winsock error. Good idea is to put some code in OnBgException of TWSocket. It can fire if you have an unhandled exception in your code. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Friday, January 26, 2007, 08:32, Veit Zimmermann wrote: > Hello Wilfried > Thanks for your reply.
