Compiling Error " NullReferenceException "

Dec 14, 2011 at 6:07 PM

Hey Guys, 

I got some trouble while compiling the code. It says NullReferenceException is not used in the user code.

and it marks this line: 

 var head = data.Joints[JointID.Head];

I don't know how to fix that. So could you may help me?


my Kinect is working perfect. I can see my skeleton in the demo viewer

Same problem to me. data is null, because no data is asigned in this code:

SkeletonData data = (from s in skeletonSet.Skeletons                                

where s.TrackingState == SkeletonTrackingState.Tracked                                 

select s).FirstOrDefault();

Hi guys,

Sorry I forgot to turn on discussion group notifications so I didn't see this thread until now.

If you get the latest version from the source control tab then you should see this issue is already fixed. It needed a simple if statement in there in case there were no skeletons on startup.
