I’m using Kinect in a WPF app and Dan Fern\u00e1ndez taught us in his quickstart video series how to stop the sensor when calling the event “Window_Closing” (which being new into C#, I guess it’s a delegate, or event handler). The thing is that if I press the Stop button in the Visual Studio UI to stop running, my Kinect doesn’t stop and then I have to run the app again and close it clicking on the X button.<\/p>\n
Is there a more general way to stop the Kinect with some event for the app Shutdown inside my code?<\/p>\n
Thank you.<\/p>\n
void StopKinect(KinectSensor sensor) {\n if (sensor != null) {\n sensor.Stop();\n\n if (sensor.AudioSource != null)\n {\n sensor.AudioSource.Stop();\n }\n }\n }\n\n private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)\n {\n StopKinect(kinectSensorChooser1.Kinect); \n }\n<\/code><\/pre>\n\n- \n
When you click the Stop button on VS you interrupt the process. So the Windows_Closing event is never called. And the Kinect don’t stop.<\/p>\n<\/li>\n

How are you defining whether the Kinect sensor has stopped?<\/p>\n
I reccomend adding exception handling around the method you are using to stop Kinect.<\/p>\n
try\n{\n StopKinect(kinectSensorChooser1.Kinect); \n}\ncatch(Exception ex)\n{\n \/\/Log Exception\n}\n<\/code><\/pre>\nIf the application was throwing an unhandled exception when attempting to stop the Kinect sensor this will give you a method of identifying it.<\/p>\n
Can you confirm whether the Window_Closing<\/code> event fires? Add a breakpoint within the function and if this is not hit then you’ll know the problem. An alternative may be to clean up the Kinect Sensor with a different event as @Bob suggested. It’s possible that when VS stops debugging the process is killed and so the event you’ve included the cleanup code for is not invoked.<\/p>\n<\/li>\n<\/ol>\nOriginally posted 2014-02-04 12:03:56. <\/small><\/p>","protected":false},"excerpt":{"rendered":"
