как ловить нажатия клавиш вне своего приложения?

Как ловить нажатия клавиш вне своего приложения? (Если форма программы неактивна)

Функция GetAsyncKeyState.
Правда нужно не слишком часто её вызывать
(перегружается и дает неверный результат)

GetAsyncKeyState работает!
Но как быть с русской раскладкой?
У нее есть виртуальные коды клавиш?

Вот тебе код. Ловит все нажатия клавиш клавиатуры (при русской раскладке - печатаются русские буквы, при английской - английские) и кнопок мыши (плюс позиция курсора).
Размещаем на форме: Text1, Text2, Label1.
