Events Not Working in C#?

[Gerald_M_1]

Hello there,

Recently got the chance to (finally) try out the camera, and while nice so far, I've been having trouble with getting events to work.  My code can be found over on my Github (https://github.com/gemisis/Pinch-Me), and when trying an event based approach, I modify the mainForm_Load method in mainForm.cs to look like this:

        private void mainForm_Load(object sender, EventArgs e)
        {
            session = PXCMSession.CreateInstance();
            manager = session.CreateSenseManager();

            if (manager == null)
            {
                Console.WriteLine("Failed");
            }
            manager.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_COLOR, 1920, 1080, 30);
            manager.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_DEPTH, 640, 480, 60);
            manager.EnableHand();

            PXCMSenseManager.Handler handler = new PXCMSenseManager.Handler();
            handler.onNewSample = this.newColorFrame;
            manager.Init(handler);

            manager.StreamFrames(true);
        }

According to the SDK Documentation, that should work, but I receive the following error :

An unhandled exception of type 'System.Runtime.InteropServices.SafeArrayTypeMismatchException' occurred in libpxcclr.cs.dll

Any ideas what could be causing this?

You need implement onNewSample. You can find details @https://software.intel.com/sites/landingpage/realsense/camera-sdk/2014gold/documentation/html/index.html?manuals_color_and_depth_picture_alignment.html
