WM_QUIT

Hi,
I've written a program that needs to execute a bit of code if it is
running when a user quits windows. How do I do this - I know it has
something to do with WM_QUIT.

Many thanks,

Richard.

PS: The program is an MFC dialog app.

Thanks,

Perhaps you are looking for the WM_QUERYENDSESSION and WM_ENDSESSION
messages.

Hello Richard
It's WM_ENDSESSION you want. Look at CWnd::OnEndSession

Not exactly. The WM_QUIT message is sent to an application when it is about
to end. It may be about to end because the user is about to exit Windows or
it may be about to end because the user chose Close from the system menu.

Check the docs for WM_QUERYENDSESSION and WM_ENDSESSION. They are the
messages most connected to Windows' exit.

It is also possible to override the base OnDestroy() function like so:

void CMyAppView::OnDestroy()
{
// Overridden to close the app
if (foo == bar)
{
DoThis;
}

CView::OnDestroy();
PostQuitMessage(0);
}

Hope it helps -

I don't think it does. The OP asked how to execute code when the user quits
Windows, not how to quit when the user closes a window.
