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

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. > 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.
