Detect when switching to battery power in laptop...

hi guys...

just a quick help required if possible...

i know i can use:
API: GetSystemPowerStatus
to get the current power status etc...

but how can i detect [live] when the power switches to AC [power cord in] and Battery power?...

- if switching to battery i need to turn off laptop monitor etc, and then enable it when back on power... - cant work out how, except a timer to keep checking, which will run the battery power faster... hooking the window could do this? ive search the forum and cant work it out...

cheers guys.

VB6 ships with a control for this sort of thing. See Visual Basic: SysInfo Control.

oh yeah sorry, forgot to mention i know about that control. i was hoping it was possible to do [without] the use of a control... - i wanna keep my install package as small as possible...

- and since u can do most the stuff of that control without using it i was wondering about this function...
