Voorbeelden

In het volgende voorbeeld wordt een aangepast verwijderingsprogramma gemaakt waarmee de Installer klasse wordt overgenomen. In de overschreven Uninstall functie wordt de UninstallAction opsomming ingesteld op basis van gebruikersinvoer. Als de invoer 'n' is, voert de aangepaste verwijdering geen actie uit op de resource in het gebeurtenislogboek dat door de gebruiker is ingevoerd. Anders wordt de resource uit het gebeurtenislogboek verwijderd.
