Re: [twsocket] THttpCli...
Hello, >Are you referring here to CamCollect or your own application? CamCollect I spent hours last night attempting to locate the problem. I went so far as to cycle power on the camera, reset to defaults, and cycle power on my computer, to no resolution. This morning/afternoon I can not get it to fail. I had it running for 3+ hours and not one hiccup. It is running now in the background and working flawless. The only hardware I did not cycle power on is the router. For Francois P., I am not calling any message pump calls, etc.. Most of my ICS callbacks are very short and post a message. For now, I will keep on the motion detection path I am on and be watchful for the error again.

CamCollect does have a download timeout to cope with a slow internet, but if you are seeing the same problem in CamCollect as your own application, it suggests the IP camera is at fault.

Re: [twsocket] THttpCli...
Hello, Thanks for the link. Watching the debug window most of the time it works like clock work. Sometimes I see the content length and then it pauses and then indicates finished and starts again. So, there is a watchdog timer but its firing is not logged. I set the frequency to 1 sec, the lowest, and the pause is about 5 seconds.

Try using my CamCollect application, it does exactly the same thing using ICS V5, see if you get the same problem, it also logs the protocol: http://www.magsys.co.uk/camcollect/ccbeta.asp Angus -- 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 -- 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 line > "Watchdog***" is the failure. The > "RequestDone Error = 3. Status = 404" that follows is my call to Abort. I see that each time your watchdog trigger, you have received exactly 37960 bytes. Strange. To know if the issue is in your program (You code or ICS code), or at the camera, you should use a network sniffer to capture data sent by the camera on the network and check if the number of bytes sent is exactly what is specified in the header. If the issue is in your program, then test with HttpTst sample program delivered with ICS. Modify it the less possible. This would confirm that the bug is in the component (not likely) or in you own code. One common cause of have data corrupted, ducplicated or incomplete, is to call the message pump from one of the events of the ICS component. You can't do that. So check if it is not the case in your application. The message pump can be called directly (Application.ProcessMessages, GetMessage, and the likes) or indirectly by displaying a modal form (including MessageBox). -- [EMAIL PROTECTED] The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- 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
