title: Changing the color of lines in a group
body: <p>I'd like to change the proprieties of the lines in my schematics.<br />
  The code works, except if lines are in a group.</p>
  <pre><code>Dim shp As Visio.Shape
  For Each shp In Visio.ActiveWindow.Selection
      '// Add cell and formula/results here:
      shp.Cells(&quot;linecolor&quot;) = 0
  Next shp
  
  Set shp = Nothing
  
  End Sub
  </code></pre>
