I am trying to load and then excel with an xml file I have created.  I have made a start but I am a bit unfamiliar with excel's interop.

      
Dim Path as String = "C:\TextXML"          
Dim excelApp As New Microsoft.Office.Interop.Excel.Application
excelApp.Workbooks.OpenXML(Path)

Open in new window

What happens with this code? Is the file missing extension on purpose?

  Dim Path as String = "C:\TextXML.XML"          
  Dim excelApp As New Microsoft.Office.Interop.Excel.Application
  excelApp.Workbooks.OpenXML(Path)

Open in new window


The code seems to do nothing not even throw an error.  I have been looking for code and this format appears several times as a solution in one question or another for opening XML in Excel 2010 via VB.Net.  Obviously there is an element missing or it is inappropriate for this problem
