Re: [twsocket] How to use TPop3Cli with SSL
Has anybody already used TPop3Cli to access POP3S (995) servers and how is it possible ? 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). -- [EMAIL PROTECTED] http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] Multithreading with TFTPClient
Hello, I want to use the FTPClient in multithreading and programed a test-program. But as I started the threads I noticed that the maximum theads are 9. If I used only one thread more nothing works. Here is an picture with my test-program with 9 threads: http://img74.imageshack.us/img74/6498/9threads3tp.png As you can see except for one thread everything works. And here is a picture with ten threads: http://img103.imageshack.us/img103/2748/10threads6ux.png As you can see only a few threads works and the others got an error like this: Logfile: 220 Speak friend, and enter USER * 331 FTP login okay, send password. PASS * 230 User logged in, proceed. TYPE I 200 Using BINARY mode to transfer data. SIZE EK040905.exe 213 7929582 PORT 192,168,2,32,4,181 200 PORT command successful.

RETR/LIST/NLST Failed QUIT 221 Goodbye. The same problem appears when there are other FTP-programs running like smartFTP or FlashFXP. I hope you have understand my problem.

Re: [twsocket] Multithreading with TFTPClient
Hello, For if you use the component in a thread. Using it in a thread means: 1. create / destroy in the Execute method of the thread I create and destroy it in the execute method of the thread. 2. set Multithreading to True I set Multithreading to True, but I saw no changes. 3. use a message pump in the thread What is a message pump ? The machine where I read mail on cannot read .png files, so I cannot see it. Here are the same picturse as jpeg: 9 Threads: http://img97.imageshack.us/img97/7742/9threads4lc.jpg 10 Threads: http://img224.imageshack.us/img224/1348/10threads2uq.jpg Joshua - Original Message - From: Wilfried Mestdagh [EMAIL PROTECTED] To: ICS support mailing twsocket@elists.org Sent: Saturday, May 27, 2006 5:55 PM Subject: Re: [twsocket] Multithreading with TFTPClient Hello Joshua, I want to use the FTPClient in multithreading You dont need to multithreading with ICS components. Possible you need a thread if you have many simultanous connections and very high data transfer to not block the main thread. Also if you have thousands of connections then it can be wise to have a few separate thread.

Re: [twsocket] Multithreading with TFTPClient
There is probably no bug into your client program. It is likely that the server you connect to accept only a limited number of concurrent connexions. The problems also appear when there are other programs running witch downloading files from a FTP-Server. And backwards if my test-programm is running, other programs slow down. - Original Message - From: Francois PIETTE [EMAIL PROTECTED] To: ICS support mailing twsocket@elists.org Sent: Saturday, May 27, 2006 5:43 PM Subject: Re: [twsocket] Multithreading with TFTPClient I want to use the FTPClient in multithreading and programed a test-program. If you do that to do simultaneous download, it is completely useless with ICS since ICS is non blocking. If you still want to go multithread, be sure to create your component at runtime from your thread's execute method. If you create the component in the constructor, then all component events will run in the main thread. And don't forget your thread need a message pump to have the events triggered.

Re: [twsocket] how to use tpop3cli with ssl
Thanks a lot, François. But I cannot estimate the time necessary to achieve my goal since I don't know Delphi but only C++ Builder. Nevertheless, if I can help somebody to make the new component POP3 supporting SSL, I shall try. -- Alain Francois PIETTE a écrit : You need ICS-SSL to do that (Contribute to the SSL Effort.

[twsocket] ICS: Sending file through THttpServer, code exemple
Hello, 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 : In HttpServer1GetDocument add the case you want : ... else if CompareText(ClientCnx.Path, '/myfile.mp3') = 0 then CreateVirtualDocument_File(Sender, ClientCnx, Flags); ... Create the appropriate procedure CreateVirtualDocument_File Then, put this code in it : procedure TWebServForm.CreateVirtualDocument_File( Sender: TObject; ClientCnx : TMyHttpConnection; var Flags : THttpGetFlag); begin Flags := hgSendDoc; ClientCnx.FDocument:='J:\myfile.mp3'; end; And you're done ! (i've seen numerous exemple of people trying to do that and no working exemple, so i thought this would be a good thing to post it) Lepidosteus PS: I first tried to build up my own header using header := ClientCnx.FVersion + ' Status ''200 OK''\r\n' + 'Content-Length: ' + inttostr(ClientCnx.FDocStream.size) +'\r\n' + 'Content-type: '+DocumentToContentType(ClientCnx.FDocument)+'\r\n' + 'Content-Disposition: attachment; filename=' + ClientCnx.FDocument +'\r\n' + '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. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
