Why does the file “DB_notify_register” change when I acquire the device?
The file DB_notify_register is changing all the time. Simply plugging the WinCE device into the charging cradle changes it. 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.
