If your hardware includes advanced backlight functionality, you can add an Advanced button to the Backlight Control Panel application as follows:
[HKEY_CURRENT_USER\ControlPanel\BackLight]
"AdvancedCPL" = "AdvBacklight"
You must include a function named BacklightAdvApplet in the AdvBacklight.dll file to enable the Advanced button. When the user chooses Advanced, the control panel application calls BacklightAdvApplet.
You can change the name of AdvBacklight.dll and the entry point by modifying the sample code for the control panel. You can find the sample code for the Advanced Backlight Options dialog box in the %_WINCEROOT%\Public\Wceshellfe\Oak\Ctlpnl\AdvBacklight directory.
