a question on VGB RRS feed

  • Question

  • After  look at the 2 videos now live on Channel 9, I still have a question on VGB.

    When running the sample DiscreteGeatureBasics inKinect browser , calling my own . gbd  file builded by  VGB replacing its "seated.gbd",it has an error:

    "System. InvalidOperationException" type of exception happen in  Microsoft.Kinect.VisualGestureBuilder.dll , but not handled in the user code

    Other information: This API has returned an exception from the an HRESULT: 0 x80004005

     How to call my own .gbd in the code?

  • Hi, oniya.

    Your problem may be not about .gdb. Try following

    1. edit your project build event (right click your project -> properties -> build events)
    2. past following codes into `post build event command line`
    xcopy "$(KINECTDFK20_DIR)Redist\VGB\$(Platform)\vgbtechs" "$(TargetDir)\vgbtechs" /S /R /Y /I

    I found this command line from sample of SDK Browser for WPF.

  • Thanks vey much for your reply.  I check this codes in the WPF, there is no problem.

    I mean it's ok when running the sample DiscreteGeatureBasics,

            /// <summary> Path to the gesture database that was trained with VGB </summary>
            private readonly string gestureDatabase = @"Database\Seated.gbd";
            /// <summary> Name of the discrete gesture in the database that we want to track </summary>
            private readonly string seatedGestureName = "Seated";
            /// <summary> Gesture frame source which should be tied to a body tracking ID </summary>
            private VisualGestureBuilderFrameSource vgbFrameSource = null;
            /// <summary> Gesture frame reader which will handle gesture events coming from the sensor </summary>
            private VisualGestureBuilderFrameReader vgbFrameReader = null;

    but it has an error when I replace "seated.gbd"  as my own gbd  for example "Drink.gbd" like this:

            private readonly string gestureDatabase = @"Database\DiscreteDrinkWater.gbd";
            private readonly string seatedGestureName = "Seated";

  • The error in this line:
              using (VisualGestureBuilderDatabase database = new VisualGestureBuilderDatabase(this.gestureDatabase))
                    foreach (Gesture gesture in database.AvailableGestures)
                        if (gesture.Name.Equals(this.seatedGestureName))

  • Is the .gdb file getting copied to your build directory? Did you mark the property as content?
