Beispiel

Im folgenden Beispiel wird ein benutzerdefiniertes Deinstallationsprogramm erstellt, das die Installer-Klasse erbt. In der überschriebenen Uninstall-Funktion wird die UninstallAction-Enumeration anhand von Benutzereingaben festgelegt. Wenn die Eingabe "n" lautet, führt das Deinstallationsprogramm keine Aktionen für die Ressource im vom Benutzer eingegebenen Ereignisprotokoll aus. Andernfalls wird die Ressource aus dem Ereignisprotokoll entfernt.
