Здравствуйте.
Не могу получить время отключения монитора.
Да и любые другие параметры.

PowerReadACValueIndex и ..DC.. доходит до них, возвращаю значения отличное от 0. Может я неправильно объявил функции(все), параметры, подсовываю не те переменные?
Может, кто занимался?
Подскажите пожалуйста.

Разобрался.
Забыл где вычитал, да ладно. Требовалось в фунции получение активной схемы 'out ... : PGUID'.
