Using the Base Notification Engine

  • 项目

The base notification engine in Windows CE is provided by the Notify component. This component requires no modification; however, you must understand how this component operates before you can properly implement your notification UI.

Windows CE handles two types of notification events: timer events and system events. Timer events indicate that a specified time has arrived, such as an appointment or a meeting. System events are triggered when the device encounters a change, such as AC power connection or disconnection.

To support these two types of notification events, the base notification engine maintains two databases: DB_notify_queue for timer events and DB_notify_register for system events.
