Re: [twsocket] Multithreading with TFTPClient
Hello Joshua, This is example of a message pump, the loop finish when WM_QUIT is received, so you have to do to destroy the thread or at finish of program: procedure TDownloader.MessagePump; begin while GetMessate(Msg, 0, 0, 0 do begin case Msg.Message of // Here you can take actions for your own custom messages // if you need to else TranslateMessage(Msg); DispatchMessage(Msg); end; end; end; So in Execute method you have something to do like this: begin // create the components // assign the event handlers MessagePump; // destroy all end; --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Saturday, May 27, 2006, 18:13, [EMAIL PROTECTED] wrote: Hello, For if you use the component in a thread.

Also if you have thousands of connections then it can be wise to have a few separate thread.

Re: [twsocket] Multithreading with TFTPClient
From the _same_ FTP server or from another FTP server ? It never minds from which FTP-Server the FTP-Cients downloading. But if other programs downloading files, my test-program becomes defective. We have to find out the source of the problem. It could be the server or it could be something in your internet connection. Or both... Try to launch several FTP transferts from the _same_ FTP server, using on program per download (for example with Windows command line FTP client). See how many simultaneous download you ca do (I repeat: from the same FTP server). Repeat the same test as above but using a different FTP server for each program instance. The result of those test will tell you if it is the server you connect to which limit the number of concurrent connections or something else. [...]and use a proper message pump, that is one with GetMessage and _no_ PeakMessage. I have found the event OnMessagePump but what is it good for ? I don't know what you mean. There are a lot of messages about message pump and the likes in this mailing list. First do a little search in the archive (Link at the support page at my website), read the articles and then is still needed, ask for more questions. -- Contribute to the SSL Effort.

Re: [twsocket] how to use tpop3cli with ssl
But I cannot estimate the time necessary to achieve my goal
since I don't know Delphi but only C++ Builder.
If you know C++, you can easily program in Delphi :-)
Just replace { and } with begin and else, = by :=, == by =,
by and, || by or, - by ., by @, return(X) by Result
:= X; Exit;, in all variable and function argument swap variable name and
datatype, include by uses, struct by record, #define by const
and you have translated your 95% of C++/ to Delphi. There are also some
syntaxe differences, but not too much. OK, some elaborated preprocessor
macros and C++ Templates are more difficult to translate as is multiple
inheritance...

Thanks a lot, François.

Nevertheless, if I can help somebody to make the new component POP3
supporting SSL, I shall try.

Francois PIETTE a écrit :
You need ICS-SSL to do that (Contribute to the SSL Effort. Visit
http://www.overbyte.be/eng/ssl.html). And the POP3 component is still on
the
to-do list. Not a big deal, but yet to be done. NNTP and SMTP are done and
is useful to understand how to add SSL to a high level component (much the
same as in a simple application using TCP).

Re: [twsocket] ICS: Sending file through THttpServer, code exemple
Looking to the mailling list, I've seen some people trying to send file in the WebServ demo of ICS. I've played around a bit with it trying to get it working, and ended up with a very simple way to do it : Thanks for your example. + 'Connection: ' + ClientCnx.FRequestConnection + '\r\n' + '\r\n\r\n'; With the correct flag and a valid file Stream associated to ClientCnx.FDocStream, but I ended up with random behaviours (unknown size by browsers, no action in firefox, opera wouldn't see when the download is over, etc ...) I guess i did it bad. You have bad end of line marker. '\r\n' are just C/C++ end of line. Translated to Delphi, it is #13#10. And you have one too much: end of header is an empty line. You have two ! You code becomes: + 'Connection: ' + ClientCnx.FRequestConnection + #13#10 + + #13#10; // Only one CRLF to end the header. Contribute to the SSL Effort.

[twsocket] Threaded Socketspy Demo
I am inquiring about the socket spy program and how difficult it would be to thread it? I examined thrdsrv1 example in ics examles and want to know where to begin. If anyone can point me in the right direction please. The current program works great but threading is required because the traffic is fairly heavy even for asynchronous sockets so I feel it needs threaded so that my main gui thread does not slow to a crawl.
