SystemEvents.PowerModeChanged Event

Occurs when the user suspends or resumes the system.

Namespace: Microsoft.Win32
Assembly: System (in system.dll)

public static event PowerModeChangedEventHandler PowerModeChanged
/** @event */
public static void add_PowerModeChanged (PowerModeChangedEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

Exception typeCondition

InvalidOperationException

System event notifications are not supported under the current context. Server processes, for example, might not support global system event notifications.

ExternalException

The attempt to create a system events window thread did not succeed.

Caution noteCaution

Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.
