SessionSwitch Event

SystemEvents::SessionSwitch Event


Occurs when the currently logged-in user has changed.

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

event SessionSwitchEventHandler^ SessionSwitch {
	static void add(SessionSwitchEventHandler^ value);
	static void remove(SessionSwitchEventHandler^ value);

Exception Condition

System event notifications are not supported under the current context. Server processes, for example, might not support global system event notifications.


The attempt to create a system events window thread did not succeed.


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.


Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.
