UserPreferenceChangedEventHandler Delegate


Represents the method that will handle the UserPreferenceChanged event.

public delegate void UserPreferenceChangedEventHandler(System::Object ^ sender, UserPreferenceChangedEventArgs ^ e);
public delegate void UserPreferenceChangedEventHandler(object sender, UserPreferenceChangedEventArgs e);
type UserPreferenceChangedEventHandler = delegate of obj * UserPreferenceChangedEventArgs -> unit
Public Delegate Sub UserPreferenceChangedEventHandler(sender As Object, e As UserPreferenceChangedEventArgs)



The source of the event. When this event is raised by the SystemEvents class, this object is always null.


When you create a UserPreferenceChangedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event-handling method, add an instance of the delegate to the event. The event-handling method is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Handling and Raising Events.
