[twsocket] C++ Builder 2009 TCP Server
Hello, I currently working with C++ Builder 2009, and I'm trying to upgrade my TCP server (based on the ICS TCPSRV demo) for this version, but I'm getting several inconsistency and linker errors. Can anyone give me a little help, on this?

Re: [twsocket] C++ Builder 2009 TCP Server
Hello,
That fixed the problem of the linker. However when I run the application and
try to connect a client, the following error appears:
Access violation at address F88BFC55. Read address F88FC55.
I'm working with the same example of TcpSrv used in icsv5, that worked
perfectly in C++ Builder 2007.
Thank you for the help

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? Thanks in advance Regards João -Mensagem original- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Em nome de João Gonçalves Enviada: domingo, 6 de Abril de 2008 13:37 Para: 'ICS support mailing' Assunto: Re: [twsocket] small but pertinent doubt Thanks for the help.

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.

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.

Thanks for the help. I you look into all these options and try to decide what's best. Regards, João -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wilfried Mestdagh Sent: domingo, 6 de Abril de 2008 11:05 To: ICS support mailing Subject: Re: [twsocket] small but pertinent doubt Hello João, No you do not need thread to implement some flow control. 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.

Re: [twsocket] small but pertinent doubt
OK, let me se if I understood The best option is to take the TCpSrv example from ICs, put it on a new Thread, and create a new Thread for each client, like the example on the MtSrv? Is this line of thinking correct? Thanks once more João -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dod Sent: sábado, 5 de Abril de 2008 8:45 To: ICS support mailing Subject: Re: [twsocket] small but pertinent doubt Hello João, One more thing, I recommend you to create the TWSocketServer into a separated thread just to avoid your appplication interface to be overloaded/non responsive in case of hudge activity. You can also dettach some client sockets and attach them into some separated thread if they may take longer time to execute (for exemple long database request or disk file activity). As ICS uses an event driven model this permit to manage very easy tons of connections but you must be responsive and make each triggered event finish as fast as possible or the next event (for exemple an other OnDataAvailable for other client) will have to wait. You may also create some worker thread that you can send thoses longer operation the release the event faster. Regards. JG Hello, JG Jus tone more thing: can youn point me to that example?

Re: [twsocket] problem with TCP server
Hello, I have to use linemode to false, since the server receives data from independent hardware modules. If I put it to true, I receive a character at a time. My problem is that the processing of some data takes a quite amount of time, and the server doesn´t processes the data, Is there any way of solving this problem?

I think this is what you want. Otherwise, it will trigger whenever the buffer is full and there is *some* data, and it is up to you to piece it together (this is what you have now). That last one is intended for streaming, where you are not expecting a specific line of data, but a constant stream of data. If you are sending commands, like other common Internet protocols, then you should set LineMode to True. The default line-delimiter is #13#10 (CarriageReturn+LineFeed), like other Internet protocols, but you can set it to whatever you want. You also should set the LineLimit property to the maximum allowed length of a line, otherwise your server may be vulnerable to DoS attacks (since it will continue growing a buffer if no delimiter is sent, and all memory may be consumed). When the LineLimit maximum is reached, an exception is triggered (which you can handle in OnLineLimitExceeded event). dZ. -- DZ-Jay [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html -- 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 -- 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
