To pick up system events use the static events in the SystemEvents class found in the Microsoft.Win32 namespace. There are a number of system events that can been listened for using this class. To detected any changes in the display settings or user preferences use the following code: // Hook the display settings changed event SystemEvents.DisplaySettingsChanged += new System.EventHandler(OnDisplaySettingsChanged); // Hook the user preference settings changed event SystemEvents.UserPreferenceChanged += new UserPreferenceChangedEventHandler(OnUserPreferencesChanged); /// <summary> /// Called when a user changes a display setting /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void OnDisplaySettingsChanged(object sender, EventArgs e) { MessageBox.Show(e.ToString()); } /// <summary> /// Called when a user changes a preference /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void OnUserPreferencesChanged(object sender, UserPreferenceChangedEventArgs e) { switch(e.Category) { case UserPreferenceCategory.Locale: MessageBox.Show("Locale Changed..."); break; default: MessageBox.Show(e.Category.ToString() + "..."); break; } }
