Saving settings when Windows terminates..?

[Eddy Van Esch]

Hi all,
When my program is terminated (clicking 'Exit', or clicking the 'X'
on the upper right), I want the programs settings to be saved.
I did this by using:

CALLBACK FUNCTION Main_DLGPROC
    SELECT CASE CBMSG
        CASE %WM_DESTROY
            SaveSettings
             ...

Now I noticed that when the program is still running when I shutdown Windows (2K),
the settings aren't saved... I thought that the %WM_DESTROY message was also
sent when windows is being shut down??
Which message shoud I use in stead?
Kind regards
Eddy

I tried the %WM_ENDSESSION message and it does the job for me.
I first thought that using this message implied serving the %WM_QUERYENDSESSION message
but it is not necessary.
I think however, when you only use the %WM_ENDSESSION (like I did), it
is possible that the %WM_ENDSESSION is called a few times in a row when some other
application(s) answer the %WM_QUERYENDSESSION to delay the windows shutdown. But in
my case this is not a problem.

Eddy, I am pretty sure you realize that WM_QUERYENDSESSION and WM_ENDSESSION will not be sent if a forced exit(EWX_FORCE flag is used with ExitWindowsEx() or the bForceAppsClosed parameter of InitiateSystemShutdown() is TRUE).

I am quite sure this brute force shutdown requires a custom applet such as a resource kit ShutDown program or one you have "rolled" yourself.

Ron,
I basically wanted to trap a 'normal' windows shutdown by the user, but
if I could trap 'every' windows shutdown (with the exception of the user unplugging
the power cord.. ) it would of course be better. Do you know of a more
'universal' way to trap a windows shutdown?
Kind regards
Eddy
