title: Retrieve Connection point names of a Visio shape in C#
body: <p>I am working with Microsoft Visio 2007 and Visual C#.
  I have a stencil with some shapes. Each connection point of each master shape in the stencil has got a name. How can I get these names in C#?</p>
  
  <p>I need a way to distinguish connection points of a shape and I thought assign a name to each connection point was the easiest one.</p>
  
  <p>P.S.
  I assigned the name to the connection points in the so called "ShapeSheet" of the master shape, i.e. the same place where one can see the coordinates of the connection points.</p>
