Exceptions

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.

Remarks

Note

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.

Caution

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