How to detect reason for App shutdown?

Hello,

I will try to explain in greater detail.

I want to write an app that will not close when user clicks on the app's close button on far top right of window but instead it should minimize to system tray.

Again when windows is shutting down I should be able to detect this situation and close my app safely.

How can I accomplish this?

TIA

Hi,
the OS sends a message. From the top of my head: WM_QUERYENDSESSION
Catch this event and do whatever you want.

Windows shutdown :

EXTERN "WinConst.WL"
id1 is system int = Event( "WinShutDown","*.", WM_ENDSESSION" )
id2 is system int = Event( "WinShutDown","*.", WM_QUERYENDSESSION )

PROCEDURE WinShutDown(msg, wParam,lParam)
// handle message
END

Thanks everyone for suggestions.

I can always do what you people have suggested but what I am looking for is a way to do this easily and it should be supported by WD's framework itself.

For example in case of VB6 we can check the mode of unloading to determine the reason for window closing in QueryUnload event.

Thanks,
