title: Accessing task completion status in PowerPoint
body: <p>I am trying to produce an application (in Python, as it happens, though using COM objects as in VBA) to export a PowerPoint presentation to a video. This is easily done using the <code>SaveAs</code> method, as in</p>
  
  <pre class="lang-py prettyprint-override"><code>pres.SaveAs("some/output/directory",ppSaveAsMP4)
  </code></pre>
  
  <p>which is fine, though I'm not sure how to finish up, as if you try to call <code>pres.Close()</code> and <code>app.Quit()</code> the video export is cancelled. Is there a function that returns the completion status of the export task (it's displayed on the progress bar, though I know that isn't exposed on the Object model)?</p>
