Brightness setting problem for 2495 and other wm5 devices

[Anil Darandale]

Hello
I am using “\HKEY_CURRENT_ USER\ControlPan el\BackLight“ registry setting to set the brightness of device through my C# application. It is working fine for 38xx and 22xx series devices but it is not working for 2495 device. Again for DELL X51 device, I need to do soft reset to reflect the registry changes but 2495 device will not reflect the changes after doing device soft rest too..

Please help me to solve this problem.

Thanks
Anil

These are embedded devices yes?
Some embedded devices don't use hive-based registries and thus, reg changes are either lost on reboot, or a special program has to be invoked to actually "save" the changes.
On one of my devices it was simply called "savereg".
It's possible that your device does not actually support registry changes outside of the system build.
It is also possible that I completely wrong on all accounts.
