If you use V6 there may be collisions with window messages in the beginning of range WM_USER posted to the same _thread where TWSocketServer created it's hidden window, are you using V6? Do you use PostThreadMessage? Do you create the TWSocketServer instance in OnCreate of TService? Only if you create it in TService.OnStart it'd run in the service thread. >> The threads only do some >> work with a database and validation of the information received from >> the machines and in the end the threads make a send call. Do you access the TWSocketClients from the worker threads directly, or do you post a messsage with the worker thread result to the thread where the TWSocketServer and its clients are running in? If it's not the message-collision-problem of V6, it may have to do with improper use of ICS in a multi-threaded env., beside the possible reasons Wilfried and Francois already mentioned. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html >> >> >> Miguel Angel Cañas C. >> >> >> >> >>> From: "Arno Garrels" <[EMAIL PROTECTED]> >>> Reply-To: ICS support mailing <twsocket@elists.org> >>> To: "ICS support mailing" <twsocket@elists.org> >>> Subject: Re: [twsocket] TWsocket server client list Error >>> Date: Thu, 12 Oct 2006 19:03:52 +0200 >>> >>> Miguel, are you running ICS in a multi-threaded application >>> or in a NT-Service? >>> >>> --- >>> Arno Garrels [TeamICS] >>> http://www.overbyte.be/eng/overbyte/teamics.html >>> >>> >>> Wilfried Mestdagh wrote: >>>> Hello Miguel, >>>> >>>> No not configuration. the socket handle is probably somewhere >>>> overwritten.
