[twsocket] TWSocketServer halts when freed

My application halts when WSocketServer is freed, not every time though. But it happens once in a few times when the application is closed. Here's the code snippet: if WSocketServer nil then begin WSocketServer.Abort(); Log('Server closed'); FreeAndNil(WSocketServer);

Re: [twsocket] broadcast sender address

Wilfried , Thanks, I am calling ReceiveFrom within OnDataAvailable. When I use ReceiveFrom my application takes 90% of the cpu and remains in this state. If i use Receive my aplication works correctly. I presume ReceiveFrom should not block but in my case it does. -rvg - Original

Re: [twsocket] SSL question

FP There is not much change required. The component is the same, except a few FP properties, events and methods required to handle certificate and the likes. FP With basic SSL, really small changes are required to turn SSL mode on and FP benefit from a crypted communication. If you add

Re: [twsocket] TWSocketServer halts when freed

Hello Jack, Do you have code in OnSessionClosed ? Because it will trigger with the call to Abort. Set it to nil beforehand. Also this is not called from within an event of TWSocketServer ? --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html http://www.mestdagh.biz

Re: [twsocket] TWSocketServer halts when freed

Hello Jack, I read your mail better now :) No need for Abort. Just Free the component. Then OnSessionClose will not fire. What will fire is OnChangeState, so be aware if you do things there like updating GUI or so. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html

[twsocket] Catching 'Stream write error' exception in CtrlSocket from within HttpCli

Hello Francois and everyone else, We have touched this subject before but the thread never got finished so I'm afraid it got lost between all of the other postings. I hope you don't mind that I start this topic in a new thread so I can focus on this single problem instead of the getting lost in

Re: [twsocket] Catching 'Stream write error' exception in CtrlSocket from within Ht

To summarize : the problem I'm having is that I cannot detect that a 'stream write error' (e.g. due to insufficient disc space) has been encountered If your application is downloading large files, it would be much better to check for sufficient disk space when the header is downloaded

Re: [twsocket] Catching 'Stream write error' exception inCtrlSocket from within Ht

Hi Angus, Another technique is to save the content yourself in the onDocData event, leaving RcvdStream set to null, then you can use your own error handling. Excellent. This is exactly what I was looking for (I did not realize that leaving RcvdStream set to NULL would allow me to take care

Re: [twsocket] broadcast sender address

Hello Robert, I have no idea. Can you try a very simple new project to demonstrate the behaviour, and also eventually try exacly the same project in D7 ? Just to be sure it is nothing wrong with Delphi 2005. --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html

Re: [twsocket] IP address before accepting a connection?

From your OnSessionAvailable, you call Accept on behalf on the listening socket. You get the socket handle. Then you call WSocket_getsockname to get the remote IP/Port. Thanks, all working now. Also needed WSocket_closesocket to close connections I want to ignore. I did look on the

Re: [twsocket] IP address before accepting a connection?

I did look on the 'wiki' page and the old help pages, but none of these WSocket_xx functions are outlined or documented. There are still a lot of things missing. There should be a chapter for the units. WSocket_xx functions are just plain functions, not component methods. So they belongs to

Re: [twsocket] TWSocketServer halts when freed

Hello Wilfried, Thanks for the quick reply. No, I don't have a OnSessionClose or OnChangeState handler. Destroying the server object will abort the socket? Anyway, I also removed Abort() but the problem is still happening from time to time as before. -- Best regards, Jack Saturday, March 4,

Hello Jack, I'm checking the log again in your first mail: main thread ($728): 7c90eb94 + ntdll.dll KiFastSystemCallRet 77d5f3de +0044 user32.dll SendMessageA 71ab8cc3 +489b WS2_32.dll WSACleanup 0048cdc4 +0018 Test.exe

Re: [twsocket] TWSocketServer halts when freed

Hello Wilfried, It looks like it. But it could be SendMessageA called by WSACleanup, which waits until SendMessageA message is processed. Maybe this is because the target window and winproc has been destroyed by TCustomWSocket.Destroy? -- Best regards, Jack Saturday, March 4, 2006, 10:24:04

Re: [twsocket] TWSocketServer halts when freed

Hello Jack, But it could be SendMessageA called by Yes possible. Jack can you try to make a simple new project to demonstrate the behaviour ? I will be glad to try debug in it. Wich delphi version do you use ? --- Rgds, Wilfried [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html

Re: [twsocket] TWSocketServer halts when freed

Hello Wilfried, It's a little difficult to make a simple project out of it because the project is kind of complicated already. Maybe I'll do that when I'm not so busy. I wonder if you can think of anything that I can hack around just to see if it'll fix the problem? -- Best regards, Jack
