Установка разрешения монитора

[MVV]

Подскажите, пожалуйста, функцию API, с помощью которой можно считать разрешение монитора (например 800 х 600), установить новое и перед выходом из программы восстановить старое разрешение.

Заранее спасибо.

Огромное спасибо!
Попробовал, вроде, все получается.
Благодарю за помощь.
