Application.Idle Event

Occurs when the application finishes processing and is about to enter the idle state.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public static event EventHandler Idle
/** @event */
public static void add_Idle (EventHandler value)

/** @event */
public static void remove_Idle (EventHandler value)

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

If you have tasks that you must perform before the thread becomes idle, attach them to this event.

Because this is a static event, you must detach any event handlers attached to this event in the ApplicationExit event. If you do not detach these handlers, they will remain attached to the event and continue to consume memory.
