[Solved] Close Application from OnTimer problem [modified]
-
Hello and good day. I have an application which runs threads and waits for all of them to be terminated before closing the application. I used a timer to check the number of threads that are still active, which successfully checked when there was no more threads. However, when I called OnClose() from the OnTimer function, the application fails to close. I needed to close the application one more time for it to successfully close. I checked and the application reads the CDialog::OnClose() in the OnClose function but it does not close when called from the OnTimer. Does anyone have an idea about this situation? Thank you very much for your help. -- modified at 1:52 Monday 22nd October, 2007

Try using calling
AfxPostQuitMessageinstead of callingOnClose.Steve

Thank you for your time and help. Though when using AfxPostQuitMessage caused the application to immediately close without calling the OnClose() which caused some leaks since I have some objects released at that function. :) Thanks again for your help!
In that case try
PostMessage(WM_CLOSE);instead.Steve

You should not call
OnClosedirectly. It's an event handler which is invoked by the MFC messaging framework in response to theWM_CLOSEmessage. That's why your call didn't work.

Actually I placed a
TRACEin theOnClosefunction to see if it works before. Since the timer is the one which calls theOnClosefunction, it printed out in the Output window the message I set inside theOnClosefunction usingTRACE. What I was wondering about was that I had theCDialog::OnClose()inside the function but it did not work. I needed to click on the close button once again to close the application. I made a breakpoint inside the function to double-check and it actually passes theCDialog::OnClose()but it won't close when called directly by theOnTimerfunction. I also triedDestroyWindowbut it really does not work ( though it passes through that line) when called byOnTimerand needed for the close button to be pressed once again to close it.
