I have an app which monitors an RSS feed. Upon an emergency,
the RSS feed is updated. The app detects the change and launches
(from the taskbar/dock) full screen, plays an alarm sound and
displays the message.
Is it possible to run this app as a service (I know that
there are several software options to enable this) - my question is
directed towards launching the full screen warning. Can I utilize
the windowing API before a user logs in if the app runs as a
I have tested this using a couple of those software options
with no success.
