Change backLight brigtness programatically

Hello!

I'm developing a program in Windows mobile 5.0 with Compact Framework 2.0
and Visual Studio 2005 that must be showing information to the user whitout
the user interaction.

I use SystemIdleTimer to prevent the turn off but the brightness still "go
down" (I lose brightness). How can I prevent this?

Thank you!

hello,

You can use SetPowerRequirement (http://msdn2.microsoft.com/en-us/
library/aa908456.aspx) with DeviceState=3DD0 (Full On / (http://
msdn2.microsoft.com/en-us/library/bb201981.aspx)).

[DllImport("coredll.dll", SetLastError =3D true)]
private static extern IntPtr SetPowerRequirement
(
string pvDevice,
CEDEVICE_POWER_STATE DeviceState,
uint DeviceFlags,
IntPtr pvSystemState,
uint StateFlags
);
