title: error C2679: binary '=' : no operator found which takes a right-hand operand of type 'IplImage *' (or there is no acceptable conversion) OpenCV
body: <p>Hi I am trying to use this code <a href="http://docs.opencv.org/doc/tutorials/objdetect/cascade_classifier/cascade_classifier.html" rel="nofollow">Cascade Classifier</a>. I got the error in title. I am using VS 2013 and OpenCV 3.0. </p>
  
  <p>I am new and I don't understand why this code works for everybody except me?
  What is the way to fix it?</p>
  
  <p>Here error line:</p>
  
  <pre><code>frame = cvQueryFrame(capture);
  </code></pre>
