Hello, 

Img0 should correspond to the camera name defined in NI MAX such as show in the image from this link

Make sure that is the correct name, and try using some CVI examples first to be sure the error is not comming from your code

It can work as well with a Webcam, it just need to be DirectShow compliant and use IMAQdx as main driver for your webcam
