This is a feature of the HTTP server: When a document is not specified, it decides which is the default resource. There is no way for the client to discover this. Well in the case where the server performs a redirection it might be possible, e.g. http://en.wikipedia.org/wiki/ - http://en.wikipedia.org/wiki/Main_Page /Tobias -- 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
[twsocket] Sending binary data
Hi, I'm using plain TCP with TWSocket and would like to send binary data. So far i've been sending text and used line mode, so I wonder how to handle binary data. One option would be to encode to say base64 and so still use line mode, but that would make data larger, so I'd prefer to send binary data directly. When sending I do know the size of data I'm about to send, so I guess I could use first few bytes to specify the length. The receiver would then use that to figure out how much to read till the end of the message. This surely isn't a rare situation, so I assume there are usual ways to do it. I would appreciate any suggestions or comments.

Re: [twsocket] Sending binary data
I'm using plain TCP with TWSocket and would like to send binary data. So far i've been sending text and used line mode, so I wonder how to handle binary data. You can emulate FTP and send the binary data on a second socket, that's closed once it's finished. Or packet up your data with start and length headers, might be slightly more secure than sending just a length alone at the start.

Re: [twsocket] [OT] CodeGear sold
CodeGear sold to Embarcadero Technologies Interestingly, Embarcadero vice president - Nigel Brown - came to Embarcadero after more than 10 years at Borland where he headed up the Developer Tools business (Code Gear) in 2006. Prior to that, he was Vice-President-EMEA, growing it to be Borland's largest and most successful region in 2000-2004. So I think Embarcadero knows exactly what they bought.

Re: [twsocket] small but pertinent doubt
Hello all, After some experiments and some (huge) line codes, I have some updates regarding this issue. I adopted TcpSrv example, I'm using TWSocketServer component and associated a new form for which client. In this way, each client updates the visual aspect of the form accordingly. I think this is the best option!? The results with 3 clients seems OK. I have some problems when I put the Sleep function in a client method, because the server stays blind to incoming data. Apart of that it is doing fine, Just one question: TWSocktetServer property Multithreaded is used for what?

First of all you may not update visual controls from within a thread, so you have to execute all this code in main thread context as well. Oke you can do that by SendMessage or PostMessage. Then if you need to display a from per client, it is the same problem. All has to be done in main thread context. So I think you will make it complicate if you use threads. You have to write thread safe code and do all updates in main thread context. So for the update of the main form table. I don't know exacly what you are doing, but if you do as follow: - client connect and send some data or whatever - when data is received you temporary store it somewhere and you disable then enable a Timer. - in OnTimer you update the table and delete the temporary data from each client. This way table will update some time after a client, and when many clients are updating it will wait a little for the update. Of cours other approachs are also possible, this is just an idea. Hope this helps. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Saturday, April 5, 2008, 19:33, João Gonçalves wrote: Let me explain why do I (think I) need a thread per client.

When some client connects, it instantiates a new Form which is associated to each client. I can view (and drag) this form along the main form. The problem is: when a client is updating it status, on the main form's table, if there is another client doing the same, the table goes crazy. I think I have to use threads in order to introduce some flow control on the mains form's table. Am I thinking straight?

Re: [twsocket] Sending binary data
Hello Daniel, It is indeed not a rare situation. Sending the length of the data first is a good idea, I do it often. another simple option is to escape some characters and still use lineMode. You have to escape the LineEnd characters as whell as the escape byte. See also http://wiki.overbyte.be for an article I wrote about sending binary data and several approach for it. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Wednesday, May 7, 2008, 13:46, Daniel Mauric wrote: Hi, I'm using plain TCP with TWSocket and would like to send binary data.
