eVB Backlite Toggle
Posted: Jul 12, 2002 @ 1:13amYou can set the registry value HKEY_CURRENT_USER\ControlPanel\OnOff to 0 or 1 to toggle the backlight on or off. The problem is that my iPaq 3630 does not recognize the change in the registry unless I power the device off and then back on. You might try sending a WM_SETTINGCHANGE message to the desktop window, etc, to see if you can get the shell to recognize that the registry value has been changed.
