is there any possibility to enable/disable programaticaly the backlight in
the PPC

There is no "generic" way as its OEM specific, which hardware are you coding
for ?

Hi,
take a look at the HKCU reg settings for 'ControlPanel\Backlight' entries -
it may help

What will you do to active/inactive backlight immediately?
Change the registry value doesn't toggle the backlight status,
the registry value takes effect after reboot, isn't it?

The universal answer is, "It depends". On our devices, changing the
registry settings actually *does* cause an immediate change, but that's not
necessarily universal. As previously mentioned, there's no global standard
that will work on all devices; we need to know the details to give a
detailed answer.

Yes, on our devices it doesn't change it automatically. We have an API
specifically for on/off and intensity.

When I said "we" I meant Applied Data Systems. As Paul said, it's
(unfortunately) not a standardized API, so every OEM has implemented it
differently.
