- Attributes
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 wraps the WM_COMPACTING message. This message is sent to all top-level windows when the system detects more than 12.5 percent of system time over a 30- to 60-second interval is being spent compacting memory. This indicates that system memory is low.
Σημείωση
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.
Προσοχή
Because this is a static event, you must detach your event handlers when your application is disposed, or memory leaks will result.
This message is provided only for compatibility with 16-bit Windows-based applications.
