how to increase or decrease contrast/brightness in compact framework

[raju]

Hai all,

I am working on the device application, where I need to adjust the
brightness and contrast of the device. Whether it is possible through
my coding or it is possible only by hardware. if it is possible through
by coding means, can you guide to achieve that.

I am working on windows ce 5.0 with vb.net.

Thanks in advance.

Check with your OEM. There's no standard for backlight or contrast
adjustment.

Your OEM will probably give you IOCTL functions and some sample C code.
You will have to convert all of that to managed code using
KernelIoControl. There will be plenty of examples on the web and these
newgroups.
