CautionThe 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(); }
