title: Access active slide / access active shape on slide in PowerPoint - VSTO
body: <p>Is there a way to access currently active slide in PowerPoint presentation using VSTO? Also is would be nice if I could get currently active Shape. I know how to iterate through slides / shapes, yet I can't find any property to figure out whether slide/shape is active:</p>
  
  <pre><code>        foreach (Slide slide in presentation.Slides)
          {
              foreach (Shape shape in slide.Shapes)
              {
              }
          }
  </code></pre>
