CeRunAppAtEvent - Using CSharp

Yesterday we looked at how to use CeRunAppAtTime for executing applications at a specific date and time. CeRunAppAtTime has a sibling, CeRunAppAtEvent, that allows for executing applications at specific OS events. The events available to trigger are the following:

    public enum CeNotificationEvent
   {
       NOTIFICATION_EVENT_NONE
       , NOTIFICATION_EVENT_TIME_CHANGE
       , NOTIFICATION_EVENT_SYNC_END
       , NOTIFICATION_EVENT_ON_AC_POWER
       , NOTIFICATION_EVENT_OFF_AC_POWER
       , NOTIFICATION_EVENT_NET_CONNECT
       , NOTIFICATION_EVENT_NET_DISCONNECT
       , NOTIFICATION_EVENT_DEVICE_CHANGE
       , NOTIFICATION_EVENT_IR_DISCOVERED
       , NOTIFICATION_EVENT_RS232_DETECTED
       , NOTIFICATION_EVENT_RESTORE_END
       , NOTIFICATION_EVENT_WAKEUP
       , NOTIFICATION_EVENT_TZ_CHANGE
       , NOTIFICATION_EVENT_MACHINE_NAME_CHANGE
       , NOTIFICATION_EVENT_RNDIS_FN_DETECTED
       , NOTIFICATION_EVENT_INTERNET_PROXY_CHANGE
       , NOTIFICATION_EVENT_LAST = NOTIFICATION_EVENT_INTERNET_PROXY_CHANGE
   };

Just as with CeRunAppAtTime, CeRunAppAtEvent resides in CoreDll.dll and its declaration are as follows:

        [DllImport("CoreDLL.dll", SetLastError = false, EntryPoint="CeRunAppAtEvent")]
       public extern static bool RunAppAtEvent(string AppName, [MarshalAs(UnmanagedType.U4)]CeNotificationEvent WhichEvent);

To set an application for execution when the system time is changed you call CeRunAppAtEvent like this:

RunAppAtEvent(@"\windows\bubblebreaker.exe", Notify.CeNotificationEvent.NOTIFICATION_EVENT_TIME_CHANGE);

And you cancel the execution of an application like this:

RunAppAtEvent(@"\windows\bubblebreaker.exe", Notify.CeNotificationEvent.NOTIFICATION_EVENT_NONE);

That's it.. Tomorrow we'll look at CeSetUserNotification as well as CeHandleAppNotifications and on Monday I'll explain why you really shouldn't use any of these APIs.
