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.

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] 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?

Re: [twsocket] small but pertinent doubt
Hello João, No, Put only the main TWSockerServer into a separated thread, that's all, this is if your applicationis not a service and has a graphical interface (one or more windows), so even if you have hudge network activity, your buttons/menus in your forms will stay responsive. Making one thread per client is non-sense using asynchronous ICS model. But eventually, you may create some worker thread or temporary thread that will proceed some longer requests without queueing for too long time all other events ICS sockets will receive. Regards. JG OK, let me se if I understood JG The best option is to take the TCpSrv example from ICs, put it on a new JG Thread, and create a new Thread for each client, like the example on the JG MtSrv? JG Is this line of thinking correct?

Re: [twsocket] small but pertinent doubt
Let me explain why do I (think I) need a thread per client. I have a C++ builder app, with a main form, that has a table with the information of the status of several clients. 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?
