V nasledujúcom príklade používa SetCursorPos, GetCursorPos, CreateCursor, LoadCursora SetCursor funkcie vytvoriť jednoduchý obyčejnou. Tiež používa kurzor a časovač funkcie Sledovať pozíciu kurzora každých 10 sekúnd. Ak pozíciu kurzora sa nezmenila v posledných 10 sekúnd, a aplikácia hlavné okno je minimalizované uplatňovanie zmení kurzor a premiestni ho na obyčejnou ikonu.
Príklad pre podobné obyčejnou je zahrnutý do ikony. Používa funkcie LoadCursor a LoadIcon viac závislé od zariadenia CreateCursor a CreateIcon funkcie.
