Hi all,
Is the above possible?
I guess I need an API call for this ? How and where to find this?
One of my new apps is used as a sort of 'dedicated' thing.
Users see an empty desktop with *only* two buttons. They only click a button to start the app.
(They have two apps they need to work with)
When they minimise the app (and some do this accidently...) the app is NOT visible anymore in a taskbar or so.
In fact there is NO taskbar...
I can check for the app not to be started two times (they do !!)
I am preventing them to kill the app other than by clicking on the 'close' button.
They ask me now: "Can you prevent the minimise ..."
Thanks,
Arno R
I'm not sure where I got this code, so if anyone wants to claim ownership be my guest.
