SystemEvents.PaletteChanged Event

 

Occurs when the user switches to an application that uses a different palette.

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

Public Shared Event PaletteChanged As EventHandler

Exception Condition
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.

System_CAPS_noteNote

This event is only raised if the message pump is running. In a Windows service, unless a hidden form is used or the message pump has been started manually, this event will not be raised. For a code example that shows how to handle system events by using a hidden form in a Windows service, see the SystemEvents class.

System_CAPS_cautionCaution

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 PaletteChanged event. This code example is part of a larger example provided for the SystemEvents class.

'Set the SystemEvents class to receive event notification 
'when a user preference changes, the palette changes, or 
'when display settings change.
AddHandler SystemEvents.UserPreferenceChanging, _
AddressOf SystemEvents_UserPreferenceChanging

AddHandler SystemEvents.PaletteChanged, _
AddressOf SystemEvents_PaletteChanged
