OnDataSent triggers after ALL data buffered in TWSocket's internal send buffer has been actually sent by winsock API send(). And there is OnSendData that triggers whenever data has been sent by winsock API send(). Whenever you call one of TWSocket's send-methods data is copied to TWSocket's send buffer first and the component the sends it asynchronously in the background. > Does it really signal that WinSock has completed sending the data? No, see above. Winsock does not provide such a callback or event. -- Arno Garrels -- 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
Re: [twsocket] Send and Shutdown oddity
what does the event OnSentData _exactly_ signal? Well, there is no such event. You have OnDataSent and OnSendData which are close. OnDataSent: This is when Winsock has accepted all data from TWSocket, that is when TWSocket buffer is emptyed. OnSendData: This is when TWSocket is able to write data to winsock. Does it really signal that WinSock has completed sending the data? There is no such event available. And even if it is, then this doesn't mean anything since the remote side still has to acknowledge it. There could be an event for that, but as far as I know TCP stack doesn't propagate this to the application.

Are you sure to use latest version? I now tried to test with Opera with option "Use HTTP 1.1 for proxies" enabled but it used to send GET requests with "HTTP 1.0". I don't know how to force 1.1 mode.

Re: [twsocket] Send and Shutdown oddity
Hello, either I have implemented the suggestion of confirming the reception of my shutdowncommand and only then closing the connection completely false or it's something quite curious and different: I found out now that the problem only happens under these conditions: - in my application's setup wizard there's the possibility to search for our Bluetooth devices and automatically pair and set them up. - when I close the wizard mentioned shutdowncommand has to be sent so that some part of my app. quits and is restarted afterwards. - only in the case when my app is running on a Laptop with Toshiba Bluetooth stack equipped and the device to be added to my application is not yet paired the shutdown command never arrives, no matter what I do. If the device has been paired previously everythign works like a charm! I've now contacted the developer of our Bluetooth library (named WCL) and hope he might shed some more light on this matter. I'm clueless now.

[twsocket] Asychronous opperation of Over Byte components - Automated processes
How should one go about coding a user initiated automated/interactive processes which use TTnCnx and TTFtpClient? The user must be able to cancel the process and respond to prompts as required by the process. If one uses On... events to trigger the next step the code become part of the GUI and is basically a state machine. Do I have any other options with these components? Can the process be encapsulated in a thread instead where the thread can wait for each task to be completed or abort etc. before it moves on?

Re: [twsocket] Asychronous opperation of Over Byte components - Automated processes
I will add that the wait process could simply be a periodic check (e.g FtpClient.State=ftpReady) amongst other code in the thread.
