WIN CE 5.0 ActiveSync Connect / Disconnect?

I need to cancel the transfer of software from Windows Mobile 6.5 to Windows CE 5.0, which currently detects when the device is in the base unit (ActiveSync is running).

I need to know when ActiveSync is running on a device so that I can prepare the device to send and receive files.

I found an article about using PINVOKE methods like CeRunAppAtEvent, but I don't know how this will work.

    bool terminateDeviceEventThreads = false;
    IntPtr handleActiveSyncEndEvent;

    while (!terminateDeviceEventThreads)
        {
        handleActiveSyncEndEvent = NativeMethods.CreateEvent (IntPtr.Zero,
                                            true, false, "EventActiveSync");
        if (IntPtr.Zero != handleActiveSyncEndEvent)
            {
            if (NativeMethods.CeRunAppAtEvent ("\\\\.\\Notifications\\NamedEvents\\EventActiveSync",
                         (int) NOTIFICATION_EVENT.NOTIFICATION_EVENT_RS232_DETECTED))
                {
                NativeMethods.WaitForSingleObject (handleActiveSyncEndEvent, 0);

                //

                NativeMethods.ResetEvent (handleActiveSyncEndEvent);
                if (!NativeMethods.CeRunAppAtEvent ("\\\\.\\Notifications\\NamedEvents\\EventActiveSync",
                                 (int) NOTIFICATION_EVENT.NOTIFICATION_EVENT_NONE))
                    {
                    break;
                    }
                handleActiveSyncEndEvent = IntPtr.Zero;
                }
            }
        }
