Represents the method that will handle the PowerModeChanged event from the operating system.

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

sender

The source of the event. Because power mode notifications are global, this is always a null reference (Nothing in Visual Basic).

e

A PowerModeChangedEventArgs that contains the event data.

Remarks

When you create a PowerModeChangedEventHandler 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.
