Re: [twsocket] TWsocket server client list Error
Hi I still have the same problem and i dont know why. My last test was: 1.SocketServer 2.Onclientconnect Show connection 3.OdataAvalilable : read the info send by other program, create a thread when the information is recieved and create a new thread with a sleep(500) instruction and the postmessage to make a send call from the main thread 4.OnClientDisconnect Show the list with all the clients. I did this in TcpSrv (adding the thread etc ) demo and into a service. The demo works fine and no blank ip port connections appeared but the service did not work and in some moment did not receive more connections. I still have 10038 errors in BgExcep. I already check buffers and all code to avoid lose of the handle. I have the demo programs, maybe i can upload or send if somebody want to test. If is possible i want to talk by phone with somebody into the ICS team, or by msn or other media and of course we can agreed a fee for the advices. I am in a difficult position because my dead line was this weekend. My mail is [EMAIL PROTECTED] ( timezone Colombia ) Thank you for the help Miguel Angel Cañas C.

Hello it's me again. The question is : It is posible tha this error could be generated by another error, i already check the source code and i see that this exception is generated in the internal close procedure but my question comes because i omit all the close calls in my code and the exception continue triggering.

[twsocket] I can't see DisconnectEvent with heavy traffic
Hi I have another question about heavy traffic behavior. TWsocketServer does not see the close socket event in time and I see a lot of connections in my server machine that are already close in the client. Looks like if my service did not process the event in time. I am missing something ? This only happen with heavy traffic. Do I have to change the configuration of my server, like changing time_wait setting etc? Miguel Angel Cañas C. _ Express yourself instantly with MSN Messenger!

Re: [twsocket] TWsocket server client list Error
Thank you for the answer Wilfried Im following your suggestios and I will test the Wsockets events today with try .. except blocks to try to find the error. However I want to ask something to, Is there a theory for the connections without IP and PORT that shows the TWsocketServer.client[i]? [04/10/2006 17:24:09:296] --D Activa[1] IP [] PORT [] because I have a procedure that check for connections to make a close socket in case that some timeotu expired, the code looks like this: //check for a valid client if WSocketServerEx.IsClient( WSocketServerEx.Client[ i ] ) then begin //Close socket. Nothing send. TTcpSrvClient( WSocketServerEx.Client[ i ] ).Close; end; I can see thar in the case of the no IP no port connections i can do a .Close call Thank you Miguel Angel Cañas C.

It comes from the message pump. This means it can come also from your code in one of the TWSocket events. To test put them all in a exception block until you found the error (if it is over there of course). Socket operation on a non socket means that somewhere some handle is overwritten. Mostly this comes because you have somewhere written outside a variable (so written [partly] to another). This is not nececary the same moment but has happend a little while before it. Also possible is that you have a pointer to a datasocket that is not exestant anymore. If you have an array of sockets or so, be sure to update it on OnClientConnect / OnClientDisconnect. Remember also that in OnClientDisconnect the datasocket in question is still there, it is called before it is destroyed (also the count argument). --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz Thursday, October 5, 2006, 09:06, Miguel Cañas wrote: Hi I am using TwSocketServer in a service application that receives information from a POS Machine (using TCP) and I am having problems with the number of clients that shows WSocketServerEx.ClientCount.
