Register that backlight is on with C#

[Carsten Marx]

Hello,
is there an easy way to register if the backlight is on or off when i
touch the screen with the stylus?
I would be nice for my app, so that when the backlight is off no action
is performed by clicking on the screen..

Thanks for any help

Regards
Carsten

I doubt there's any way to do it - definitely not a standard way. The
backlight is supposed to come on when the touch panel gets an interrupt -
that's handled by the touchpanel driver communicating with the backlight
driver through the OS. Getting in between them would be difficult. I'm
also not aware of any standard API for determining the current backlight
state.
