Consuming WMI Events

Question

I'm trying to use WMI to get notifications when the brightness of an Monitor. I found a WMIEvent class on MSDN called WMIMonitorBrightnessEvent http://msdn.microsoft.com/en-us/library/aa394537(v=VS.85).aspx but I can't really find any info on how to use it. I've come across a few samples for consuming WMI Events, but none of them seem to work.

Any examples would be helpful.
