Voorbeelden

In het volgende voorbeeld wordt de ServiceController klasse gebruikt om de apparaatstuurprogrammaservices op de lokale computer weer te geven.

Opmerkingen

GetDevices retourneert alleen de apparaatstuurprogrammaservices van de lokale computer. Als u de niet-apparaatstuurprogrammaservices of -services wilt ophalen die geen stuurprogramma's zijn, roept u de GetServices methode aan. De twee methoden bieden samen toegang tot alle services op een computer.
