Re: [twsocket] TWsocket server client list Error
hi Arno I am running ICS in a nt service and i am using multi threading but the socketservers is in the main 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. Miguel Angel Cañas C.

I colud no t find the error that triggger the exceptior but i find that for each exception i have an 'empty' connection (no ip no port). I will make a little explanacion of my code. My service is a tcp server very similar to the example that comes with ICS componets. My code look like this WSocketServerExClientConnect() OnDataAvailable := ClientDataAvailable; OnBgException := ClientBgException; ConnectTime := Time writeinTxtFile( '--Conexiones Activas : ' + IntToStr( WSocketServerEx.ClientCount ), true ); for i := 0 to WSocketServerEx.ClientCount - 1 do begin writeinTxtFile( Format( '--Activa[%d] IP [%s] PORT [%s]', [ i, WSocketServerEx.client[ i ].getPeerAddr, WSocketServerEx.client[ i ].getPeerport ] ) );

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.
