[twsocket] Problems with TWSocket.close and DLL
Hello, I'm writing a application in D2006 and build a communication dll for it. The communications dll encapsulates different communication methods (for USB, ethernet...). Ethernet communication is done via ICS TWSocket, the version included on the partner cd. The DLL has a data module which has one single TWSocket for all incomming data and for each outgoing connection a TWSocket is created dynamically. The instance of this socket is stored in a TObjectList together with other relevant information. When the first connection is opened a seperate thread within the DLL is created for handling of the windows messages (needed by TWSocket and other components as well). This works so far until the point is reached where the DLL is freed. The DLL is used statically in another DLL which has a thread for each connection too. This 2nd dll is loaded dynamically. When it is freed via free library, its finalization checks if there are any open connections thus threads) left. If yes, they all get freed and by freeing them each connection in the first dll should get closed too. With TWSocket this doesn't work, because socket.close seems to hang and the 1st DLL never reaches the statement after the close. Pseudo code is like this: - write a marker to the windows eventlog (debug output) - call socket.close; - sleep(25); - write a marker to the windows eventlog (debug output) - call socket.free; The 2nd marker is never reached!!! In my test app. it's as follows: a connection is opened, data is send and when closing the form, freelibrary for the 2nd dll is called. It hangs the application for some time and a look in the eventlog reveals that the 2nd marker never gets written. If you try to close the app. again after halfe a minute itgets closed like nothing had hapened. If one does the same thing (same test app.) but uses a RS232 connection instead of the UPD one via TWSocket it works well when you close the app. What can this be? I think the bug was already in the dll back when I used D2005 for development, I don't think it's specific to the ICS version on the D2006 partner DVD.

Re: [twsocket] Problems with TWSocket.close and DLL
Hello Markus, Why not .free the socket thru a message sent in .OnClose event ? This is a better way than doing a sleep(x) that tends to defeat asynchronous ICS model, you' better thing in term of events. Also you could not free you TWSocket but re-use later as you maintain a TObjectList of already create TWSocket so just add some FUsed:boolean; property to see if it is still used. But may be François will answer better.

Re: [twsocket] Problems with TWSocket.close and DLL
Hello, Think that ICS is fully asynchronous and event driven, it's a different approach comparing to Indy or other Socket components and also comparaing to RS232 programming where synchronous mode is usual. With ICS (server or client mode) you can make or receive thousand of connexions. All data received will simply trigger an event. If a socket break, then you'll be also event triggered. So you manage incoming data in the event, no need to sleep or create one thread per connexion but you could create a worker thread for lengthly operations that would slow down event loops. Also when you send data you send them all and let ICS "really" finish the sending and trigger DataSent event so you could send "a bit" of data and send more at each OnDataSent.

Hm, "too" sounds like each client connection runs in it's own thread? This 2nd dll is loaded dynamically.

If you _must wait nevertheless, MsgWaitForMultipleObjects() may be an alternative. However I haven't understood your DLL/thread design, and in which threads your sockets run. If you don't get a better answer give it another trial with a more detailed description of the thread design and how sockets are created/attached to threads.

[twsocket] C++Builder 2006 and ICS
I downloaded the latest ICS BETA and installed it in BDS 2006, but I cannot access the components in the C++Builder personality. They seem to be in the Delphi personality only. I need them in the C++Builder personality. Can anyone help with getting the latest BETA installed in BDS 2006 so the components are available in the C++Builder personality? By the way, it seems I also have this problem with some other components. I need them in the C++Builder personality but they're only available in the Delphi personality.

[twsocket] TWSocket and Close problem
Hello, (now writing from my other account) just to clarify some things: - I want the socket to be closed and freed at this point, because the DLL who provided communication via sockets for the other levels is unloaded and opening or closing communication channels is done rather seldom in my app. (at start and at end of it) - the sleep was put there by me to give the socket some time if still data is pending or similar, but I will remove it now. - there is still another thread active in this very same dll who only powws Windows messages (until WM_Quit or terminated) - the dll just seems to hang at this close call. - I might have reinvented TWSocketServer, but since I must be able to remember connection data for other types of connections (like USB or RS232) I need a unified sheme for this. So a TObjectList where another Object is stoored for each connection is used, and it is a UDP one the socket property of that other object is set up properly.

Re: [twsocket] C++Builder 2006 and ICS
It is unfortunate if a new package is necessary. Why can't the Delphi and C++Builder personalities share the same components in BDS 2006? I was hoping this would be a huge plus for BDS 2006, but if separate installs and packages are needed, then that really puts a damper on it. Where can I get a package for C++Builder 2006 or can someone guide me in creating my own? -- Albert Wiersch AI Internet Solutions [EMAIL PROTECTED] http://www.htmlvalidator.com/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Arno Garrels > Sent: Tuesday, January 31, 2006 2:11 PM > To: ICS support mailing > Subject: Re: [twsocket] C++Builder 2006 and ICS > > > Albert Wiersch wrote: > > I downloaded the latest ICS BETA and installed it in BDS 2006, but I > > cannot access the components in the C++Builder personality. > > I made a separate package for BCB.

Re: [twsocket] C++Builder 2006 and ICS
I found a solution! 1. Uninstall the ICS package from BDS 2006. 2. Exit BDS and run the Delphi Win32 personality. 3. Load the ICS BDS 2006 package. 4. Goto the Project Options->Linker and select "Generate all C++Builder files". Click OK. 5. Compile and install the package. 6. If you exit and load the C++Builder personality now, the components should now be in the Tool Palette. -- Albert Wiersch AI Internet Solutions [EMAIL PROTECTED] http://www.htmlvalidator.com/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Albert Wiersch > Sent: Tuesday, January 31, 2006 1:38 PM > To: 'ICS support mailing' > Subject: [twsocket] C++Builder 2006 and ICS > > > > I downloaded the latest ICS BETA and installed it in BDS > 2006, but I cannot > access the components in the C++Builder personality.
