Storing selected edges in listbox and parsing through on button command

Hi All,

I am working on a small add-in for Solidworks in which a side task bar is displayed with a listbox.  The user selects one/more edges of a part and clicks a button that adds the edges to the listbox.  A second button command then fires calculations based on the edges in the listbox.  


So I need a way to store the ID of each edge so I can reference them later in the calculations. 

As a test I started with this code to see if I can at least show all the IDs of selected edges.


Dim swModel As ModelDoc2 = swApp.IActiveDoc2
Dim sMgr As SelectionMgr = swModel.SelectionManager
Dim sEdge As Edge
Dim sType As swSelectType_e


For index = 1 To sMgr.GetSelectedObjectCount2(-1)
   sType = sMgr.GetSelectedObjectType3(index, -1)

   If sType = swSelectType_e.swSelEDGES Then
            sEdge = sMgr.GetSelectedObject(index)
   End If


The result I get is all zeroes / "0" instead of what I would imagine the would be the internal ID that would let me access that edge later on.


So I'm sure I'm missing something.  How would I go about storing a reference to each selected edge that I can use to reference later on?


I appreciate any help you can give!
