ICS will never actually freeze your application, though with very fast transfers it happens that the GUI freezes since Windows puts WM_PAINT messages into the message queue only when the queue is empty. So it's IMO a good idea to use a worker thread to keep your GUI responsive. In order to detect timeouts you do not need a worker thread, just use a TTimer to check whether something was received or sent in intervals. In OnProgress event you could simply set a flag which is reset in OnTimer event. -- Arno Garrels to overcome this problem I thought that I can, - Create a thread to make the ftp transfer - Assign OnProgress event, and in this event handler PostMessage to the main application window, - In main thread if message from thread does not come for long time, kill the thread and restart the uploading by creating another thread instance. Is this approach is a proper solution or what would you suggest?

Re: [twsocket] Ftp freezing
I am using tftpcli in passive mode to upload files, while uploading a file, for some reason if a connection problem occurs in the middle of the transfer, the program freezes , There is no reason inside ICS which could freeze the program since it uses async operation. Please try the same upload using FtpTst sample application delivered with ICS to see if it comes from your own coding. If it occurs with FtpTst, then do some more testing: 1) Try on several other computers 2) Check your security products such as firewall, anti malware and similar. Some are bugged and make async winsock operation blocking ! to overcome this problem I thought that I can, - Create a thread to make the ftp transfer - Assign OnProgress event, and in this event handler PostMessage to the main application window, - In main thread if message from thread does not come for long time, kill the thread and restart the uploading by creating another thread instance. Is this approach is a proper solution or what would you suggest? This would be just a work around. You should be find the root cause and suppress it. -- francois.pie...@overbyte.be Author of ICS (Internet Component Suite, freeware) Author of MidWare (Multi-tier framework, freeware) 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
