Hello Markus, Just free the socket. It will self close when it is connected.
Your code will work of course. When connected it will exit the loop immediatly because OnSessionClose is called from within the Close method, and when not connected it will time out. But it is not needed. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Wednesday, April 26, 2006, 17:48, Humm, Markus wrote: > Hello, > I've got the following problem and look for the real cause: > (don't know yet whether TWSocket is involved or not, but looks like) > I've a dll with a message pumping thread and at least one sending > TWSocket and one seperate receiving TWSocket. > The very same DLL provides also other communication ports (e.g. RS232). > I've written several test programs now, two of the tree work fine, the > third now crashes when closing it, but only when the UDP-Sockets > communication method is tested for e.g. RS232 it works fine. > The other two test app.s are one which loads the dll via load library, > the other one statically (external...) and is DUnit based.
