This is a problem with the
monitor florescent tube (backlight) that is mounted on the notebook NOT with an external display via serial port or RS 232 technology.
I changed my OS from Windows XP MCE to XP Pro and my brightness controls no longer work. I am looking for a way to address the backlight with an OCX or API call using Visual Basic.
Here is my answer in C
http://msdn.microsof...2656%28VS.85%29.aspxI dont write C but if I could get that in an OCX I am sure I would be in business.
I could instruct the OCX from Visual Basic.
To be honest this is a HUGE problem. I am learning that ALL notebook manufacturers do it this way. They release a model with the OS installed and a driver to take care of the florescent monitor tube / baklight. If you change the OS at any time you very possibly will not find a driver for that model with that OS. I have seen and read thousands of articles so far of people asking desperately for a fix. If I can get an OCX method I intend to make a simple way to address the backlight (florescent tube behind monitor) directly and behave exactly the same as the simple driver is supposed to and I will offer it for free to anyone who wants it.
