Represents the method that will handle the UserPreferenceChanging event.

[Visual Basic]
<Serializable>
Public Delegate Sub UserPreferenceChangingEventHandler( _
   ByVal sender As Object, _
   ByVal e As UserPreferenceChangingEventArgs _
)
[C#]
[Serializable]
public delegate void UserPreferenceChangingEventHandler(
   object sender,
   UserPreferenceChangingEventArgs e
);
[C++]
[Serializable]
public __gc __delegate void UserPreferenceChangingEventHandler(
   Object* sender,
   UserPreferenceChangingEventArgs* e
);

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the UserPreferenceChangingEventHandler delegate declaration.

sender

The source of the event. Because user preference changes are global changes, this object is always a null reference (Nothing in Visual Basic).

e

A UserPreferenceChangedEventArgs that contains the event data.

Remarks

When you create a UserPreferenceChangingEventHandler 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 Events and Delegates.
