[# KINECTSDK] HowTo: Detect the sensor state change and sensor disconnectionIf we go ahead we can see in KinectSensor we have a special event to capture the States of sensors: StatusChanged.This event also can be used to detect when you connect or disconnect a sensor to the USB port. An example with this code in a console application: ... When we launched the application we can see how the timestamp, shows a small difference between the connected sensor and active sensor (lines 2y3 vs 4.5 lines) 1: 20:23:32.9637224 - Start sample application 2: 20:23:40.0351074 - New Status: Initializing 3: 20:23:40.0351074 - Sensor Status: Initializing 4: 20:23:44.7783652 - New Status: Connected 5: 20:23:44.7783652 - Sensor Status: Connected 6: 20:23:51.2279666 - New Status: Disconnected 7: 20:23:51.2279666 - Sensor Status: Disconnected 8: 20:23:59.2548372 - New Status: Initializing 9: 20:23:59.2558370 - Sensor Status: Initializing 10: 20:24:03.5861851 - New Status: Connected 11: 20:24:03.5861851 - Sensor Status: Connected 12: 20:24:08.8158976 - New Status: Disconnected 13: 20:24:08.8158976 - Sensor Status: DisconnectedIf we also want to take advantage of this event to initialize the sensor, we must bear in mind that we can only do so when the State of the sensor is "connected". The complete example below shows one way of doing it.

The code seems to have a small error. I tried it, and while it does start, it does not report the status of my Kinect for Windows sensor. I think this *may* have something to do with line 27, where in the list of arguments for console.writeline there is "ect.Status". Did you mean e.Status, or _kinect.Status? Or is it something else entirely?

Yep, there was a bug on line 27 (now fixed). I switched it to e.Status and it seems to work for me.

In looking at the original post though, looks like the author later updated it to use _kinect.Status. Either one should work.

(Just a side note, I cannot take any credit for this project/code. The original author, http://elbruno.com/, deserves all the kudo's and credit, etc for it. I'm just the messenger...
