SystemEvents.DisplaySettingsChanged Event

Occurs when the user changes the display settings.

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

public static event EventHandler DisplaySettingsChanged
/** @event */
public static void add_DisplaySettingsChanged (EventHandler value)

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

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

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.

The following code example demonstrates how to monitor the DisplaySettingsChanged event. This code example is part of a larger example provided for the SystemEvents class.

static void Main() 
{         
    // Set the SystemEvents class to receive event notification when a user 
    // preference changes, the palette changes, or when display settings change.
    SystemEvents.UserPreferenceChanging += new 
        UserPreferenceChangingEventHandler(SystemEvents_UserPreferenceChanging);
    SystemEvents.PaletteChanged += new 
        EventHandler(SystemEvents_PaletteChanged);
    SystemEvents.DisplaySettingsChanged += new 
        EventHandler(SystemEvents_DisplaySettingsChanged);        

    // For demonstration purposes, this application sits idle waiting for events.
    Console.WriteLine("This application is waiting for system events.");
    Console.WriteLine("Press <Enter> to terminate this application.");
    Console.ReadLine();
}
