I am new to all of these languages and I am developing with the Kinect for my senior design so I decided to look at these videos to start out.  How come when I combine the code from 2.Setting up the Environment and 3. Camera Fundamentals, I no longer get the camera to display an image.   I have the following code which is just basically the code from video 2 and 3 combined.  If I use the bitmap and byte[] i can get the image but not if I change it like the author of the video does.  Can someone help me?
