Re: [twsocket] TWsocket server client list Error
Hi Well I finally found the error that generates the abnormal behavior in client list. My service receives some data form a POS machine and then do some work in a DB (SQLServer using ADO). I do all the DB process and validation in a thread and finally I send the results to the POS machine. It looks like this 1. Onconnect (SocketServer) 2. OnDataAvaliable ( if data correct New thread created) 3. New Thread( Precess Info) 4. New thread( PostMesage to send answer) 5. New Thread(Destroy) 6. OnClientDisconnect First mistake: I put TWSocketServer in the service in design time. Correct: I Created in OnStart ( Arno suggest this thank you Arno ) Second Mistake: My threadÂs create method had this instruction begin ADOconn := TADOConnection.create( nil ) //This instruction generates the error and freeze the service after some hours running   . End; Correct: I put my ADOConnection into a DataModule and I create the Datamodule in the Excecute method, not in threadÂs create method.

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.

hi Arno I am running ICS in a nt service and i am using multi threading but the socketservers is in the main thread.

Re: [twsocket] TWsocket server client list Error
Hi Wilfried Sorry but I didn-t have time to do a test program, I am in a dead line and I have another errors to fix too but this one is critical to me because the service is starting to loose connections. Let me explain better: 1. The connections Startt to grow because of the processing time, the service is processing as fast as possible. 2. I have like 50 to 60 connections in the client list (Wsocketserver.clientcount) 3. I have the first Error 10038 in function Disconnect (closesocket) Socket operation on non-socket 4. IÂm using TcpView (http://www.sysinternals.com/Utilities/TcpView.html) and I saw that the new connection got into the list of the program but next disappeared and my program didnÂt run the onConnect event, at least no t the part that is into my program. 5. After that I saw the connection with no IP no port info and the Hsokcet value = -1. Could it be a configuration problem ? in the TWsocket server ? or in the server PC?

Re: [twsocket] TWsocket server client list Error
Hello Wilfried Today i made some test and the results are not good for me. I colud no t find the error that triggger the exceptior but i find that for each exception i have an 'empty' connection (no ip no port). I will make a little explanacion of my code. My service is a tcp server very similar to the example that comes with ICS componets. My code look like this WSocketServerExClientConnect() OnDataAvailable := ClientDataAvailable; OnBgException := ClientBgException; ConnectTime := Time writeinTxtFile( '--Conexiones Activas : ' + IntToStr( WSocketServerEx.ClientCount ), true ); for i := 0 to WSocketServerEx.ClientCount - 1 do begin writeinTxtFile( Format( '--Activa[%d] IP [%s] PORT [%s]', [ i, WSocketServerEx.client[ i ].getPeerAddr, WSocketServerEx.client[ i ].getPeerport ] ) ); end; ... end WSocketServerExClientDisconnect( ) ... for i := 0 to WSocketServerEx.ClientCount - 1 do begin WriteTxtFile( Format( '--D Activa[%d] IP [%s] PORT [%s]', [ i, WSocketServerEx.client[ i ].getPeerAddr, WSocketServerEx.client[ i ].getPeerport ] ) ); end; .. end; When i have like 150 or 200 connections in the list i have something like this in my txt file [05/10/2006 11:21:15:845] --D Activa[165] IP [] PORT [] and if i try to do .close call this call works but nothing happen, not to the list no exception, no disconnect event nothing. This behavior repeats only with heavy traffic. If i start a new valid connection after i while this connection is added to the end and works fine if no heavy traffic start again but i can free the used positions with empty connections (no ip no port).

The only reason I can think about is that there is eather an exception error in the OnClientDisconnect event, or something with an overwritten pointer. Never had that situation.

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.

Re: [twsocket] TWsocket server client list Error
Hello Miguel, BGException is background exception. 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.
