- If your working thread has called accept(socket,..) and is currently
waiting for a connection, you may close the socket (closesocket(socket)
to force it to return.
- In OnClose() function, you need to call closesocket(m_ThreadParam->socket)
- You may want to add this new member "socket" in your ThreadParam struct
Good luck!

Thanks to all of you. I will try this when I get home. I just hate when you are running your app in debug mode and as soon as the application stops you get a "Memory leak detected" in your debug window 
Especially since this is a server application I don't want to many memory leaks going on, throught the course of the day it may kill the server, even though at this time the app only generates one thread for the server function, but it generates multiple threads for each connection...
Thank you, and I will try all of your suggestions when I get home. However, if anyone has more advice I'm am still open to hearing them.

"In my ThreadParam struct I added a variable bool Stop. When I start the thread I set stop to false and in the while loop I use an if statement to check for Stop. If it is true I break out of the while loop so the thread can close safely. I change Stop to true in the WM_CLOSE message of the MAIN GUI interface--No success."
Why doesn't it work? Most likely your code to check the bool value was not executed because the worker thread was blocking (waiting for other things). There is no way to terminate a worker thread within itself effectively. If you have the thread handle, you can call TerminateThread from outside, but there are warnings against using TerminateThread (see MSDN).
User interface thread is different because it has a message pump, so it can process the quit message. But it changes the way your program works.

First thing that popped into my head was "is 'Stop' a volatile variable and is it a managed resource? (Do you use a critical section to control who is accessing it? Suggestion: If this is how you want to stop your thread this could work. I would recommend using a short instead of a bool. This way it can have states. Ie. 0=Thread running, 1=Request a stop and 2=Thread stopped. Then you GUI thread can check this before actually closing the window.
Second thing that popped into my head is that Stop shold work uness the code you are using in your while loop is blocking and thus never checking Stop.

Just clarifying the acutual code in the while loop now is:
listen(sListen, 5);
while (1)
[
if (pThreadData->Stop)
break; //Just exit the while loop and let the thread close out
]
closesocket(sListen);
WSAcleanup();
return 0;
It is just bare minimum because I'm trying to see why I get the memory leak. I have nothing else in the while loop pertaining to the socket.

There's no reason for your thread to block with your example except
that your thread is taking up all the CPU. Try putting a Sleep(0) in your
loop. Make sure your memory leak is not from "pThreadData"

I'll try putting a sleep call in there. I'm hoping that pThreadData is not the leak since I have this pointing to a member variable in the outer class that is defined as my ThreadData struct. I am *assuming* that since the variable is declared on the stack, and space not dynamically allocated, it goes out of scope, and it's memory released, when the class does. Please let me know if this assumption is not correct 
**UPDATE**just thinking about it pThreadData is not the leak because if I remove the while loop there is no memory leak detected. The leak detected is object CWinThread hopefully this additional information is helpful.

Fine, I thought you allocate your ThreadData with "new" or malloc...
If you are using a CWinThread object, in your case, Set "m_bAutoDelete = TRUE"
after starting your thread. By the way, it's not necessary to use CWinThread
since what you want is a working Thread.

Ah...that could be the step I'm missing I'm not inheriting from CWinThread so to speak, but it is what is returned when you call AfxBeginThread() I was told not to call CreateThread from within an MFC function or be forewarned about doing so...I don't even know if that is correct now since I have gone through several source codes that utilize MFC and do call CreateThread?!?! Clarification anyone?

Okay, unless you want to save the returning pointer of CWinThread
there's little help to call AfxBeginThread since _beginthreadex
is all you need.
- Yes, you still can change "m_bAutoDelete" to TRUE
- Yes, it's better to call _beginthreadex or _beginthread in MFC
but you may still get away with it by calling CreateThread.

Ernest thanks for being patient. Yeah all the literature I have on MFC always say use AfxBeginThread, and thanks for elaborating on the different thread calls.
I wonder why the PSDK or the many books I HAVE on MFC don't mention those functions?!?!
Thanks!

Might not get into the while until the listen call returns, i.e. something connects.
As stated above, might want to fake a connection on 127.0.0.1 to kick the listen off its perch when shutting down.

|

Checked for that with the debugger was able to start stepping through the while loop. That gave me the impression that I was in there, hopefully the while loop is not split off into it's own thread that runs while listen is tied up That would be just my luck...

Ok - my impression was that the listen would block until it rec'd a connection. Are you using the WSAAsyncSelect or WSAEventSelect to get around that?
Thats different then.
Never mind.

I need to have a function to delete a directory. Every month or week I will create a directory and store files inside. After so many weeks or months, it should auto delete itself. I have looked but don't know how to enum or search the directories on some disk and then do my thing. Any suggestions?
Thanks in advance!
|
|
|
|
|
Use ::FindFirstFile / ::FindNextFile to enumerate the directories , and ::RemoveDirectory to delete what you want
|
|
|
|
|
Use SHFileOperation(), which doesn't require the dir to be empty.

i'm writing an application that creates CWebBrowser Controls in a form view at run time, and i need to catch the these control's events. All the examples i've seen use the class wizard to generate the Event Sink Map.
Is there a way to catch all the events in the FormView and then determine wich control fired the event ?
Thanx

Hey I'm working on a project and I am having some memory leaks and access violations that are driving my up the wall. I was wondering if someone would be willing to do a code review. It shouldn't take too long it's (at this moment) only 1000 lines. I'd ask someone i know to do it but I am the only person who know c++. Thank you.

Hello everybody again!
Nobody can help me?
Who may help me with such question
The size pInfo->m_rectDraw always is less than structure CPrintInfo, than the real size of a sheet.
Whether it is possible to determine displacement m_rectDraw from the left top corner of a sheet, if yes, as?
Best regards,

Hi,
I would like to do something very innocent.. just print a normal little bitmap with the logo of my product in a page...
Well, I have started reading about that, and seems that is a nightmare to do that !, take the bitmap, convert it from DDB to DIB, and then ok, there is no class in MFC to handle dibs... ?????
Is there any easy way to do that ? ( I mean, print a normal bitmap ( with 3 or 4 colors not more)).
Thanks, Bye !

I'm designing a custom control based on the CWnd class that displays a card
for a card game. I have been able to get the control to send back messages
to the parent dialog (MFC Dialog App) but I have had no end of trouble trying
to figure out which card has been clicked when they are overlapped. I've
tried messing around with the z-order, but have had no success. Any ideas?

Hello, I'm trying to construct a 3D image using OpenGL by getting the coordinates from a series of bitmap files. Each bitmap contains a cross section of the shape at a different height. So I need to get 2D coordinates from the files to construct my image. How do I get coordinates from a bitmap picture, supposing that I have marked all the necessary coordinates with red dots in the bitmap files. (note: there is no red in the bitmap otherwise).
