Beispiele

Im folgenden Beispiel wird ein benutzerdefiniertes Deinstallationsprogramm erstellt, Installer das die-Klasse erbt.The following sample creates a custom uninstaller that inherits the Installer class. In der überschriebenen Uninstall Funktion wird UninstallAction die Enumeration auf der Grundlage von Benutzereingaben festgelegt.In the overridden Uninstall function, the UninstallAction enumeration is set based on user input. Wenn die Eingabe "n" ist, führt das benutzerdefinierte Deinstallationsprogramm keine Aktion für die Ressource im Ereignisprotokoll aus, das vom Benutzer eingegeben wurde.If the input is "n", the custom uninstaller will not take any action on the resource in the event log entered by the user. Andernfalls wird die Ressource aus dem Ereignisprotokoll entfernt.Otherwise, it will remove the resource from the event log.
