Good morning,
I'm developing in C# with Visual Studio 2008 .NET and .NET Compact framework
2.0 on Windows CE 5.0 .

Which are the libraries that by means I can control display backlight and,
generally, display turn on/off ?

Thank you for your help.
Emilio.

There is nothing in the framework that covers this. You will have to resort
to PInvoke and call DeviceIOControl in order to access the "backlight
control interface" .
Note that this can better be implemented as a library function using
unmanaged code (C/C++).

Willy.
