    CeSetUserNotificationEx troubles

    Hi everyone,

    I've been trying out examples and reading documentation
    on CeSetUserNotifi cationEx for a couple days now and
    still cannot find the problem in my code. All I want to
    do is launch an application when the PPC wakes up. I'm
    deploying the solution on a Siemens SX56 with PPC
    3.0.12039.

    Here's my code. CeSetUserNotifi cationEx always returns
    me an IntPtr.Zero regardless of what I try.

    public class Utils
    {

    [DllImport("core dll.dll", SetLastError=tr ue)]
    private static extern IntPtr CeSetUserNotifi cationEx(
    IntPtr h,
    CE_NOTIFICATION _TRIGGER nt,
    CE_USER_NOTIFIC ATION un
    ) ;

    private unsafe class CE_NOTIFICATION _TRIGGER
    {
    public UInt32 dwSize;
    public UInt32 dwEvent;
    public UInt32 dwType;
    public char *lpszApplicatio n;
    public char *lpszArguments;
    public SystemTime startTime ;
    public SystemTime endTime ;
    }

    private unsafe class CE_USER_NOTIFIC ATION
    {
    public UInt32 ActionFlags ;
    public char *pDialogTitle ;
    public char *DialogText ;
    public char *Sound ;
    public UInt32 MaxSound ;
    public UInt32 Reserved ;
    }

    public struct SystemTime
    {
    public UInt16 Year ;
    public UInt16 Month ;
    public UInt16 DayOfWeek ;
    public UInt16 Day ;
    public UInt16 Hour ;
    public UInt16 Minute ;
    public UInt16 Second ;
    public UInt16 MilliSecond ;
    }

    struct Constants
    {
    public const int NOTIFICATION_EV ENT_NONE = 0;
    public const int CNT_EVENT = 1;
    public const int NOTIFICATION_EV ENT_WAKEUP = 11;
    }

    public unsafe static void AttachAppToStar tup(
    string executable, string arguments )
    {
    CE_NOTIFICATION _TRIGGER nt =
    new CE_NOTIFICATION _TRIGGER();
    CE_USER_NOTIFIC ATION un =
    new CE_USER_NOTIFIC ATION();
    IntPtr h;

    try
    {

    fixed( char *appName =
    executable.ToCh arArray() )
    {

    if( ( arguments == null ) ||
    ( arguments.Lengt h == 0 ) )
    {
    arguments = " ";
    }

    fixed( char *appArgs =
    arguments.ToCha rArray() )
    {

    nt.dwSize = (uint)Marshal.S izeOf( typeof
    (CE_NOTIFICATIO N_TRIGGER) );
    nt.dwType = Constants.CNT_E VENT;
    nt.dwEvent = Constants.NOTIF ICATION_EVENT_N ONE;
    nt.lpszApplicat ion = appName;
    nt.lpszArgument s = appArgs;

    h = CeSetUserNotifi cationEx(IntPtr .Zero, nt, un) ;

    MessageBox.Show ( "h is " +
    ( (h!=IntPtr.Zero ) ? "not " : "" ) +
    "null." );

    }
    }
    }
    catch( Exception E )
    {
    MessageBox.Show ( E.ToString() );
    }
    }

    }

    --------------------------

    This is the method in a Windows Form object that calls
    the wrapper.

    private void menuItem1_Click
    (object sender, System.EventArg s e)
    {
    string executable =
    Assembly.GetExe cutingAssembly( ).GetModules()
    [0].FullyQualified Name;
    Utils.AttachApp ToStartup( executable, null );
    }

    I appreciate any help you can provide!

      Hi,

      Take a look at http://www.innovativedss.com/forums/...p?TOPIC_ID=127

      also , I think that you will find better answers in the
