title: Iterating through all the cells in Excel VBA or VSTO 2005
body: <p>I need to simply go through all the cells in a Excel Spreadsheet and check the values in the cells.  The cells may contain text, numbers or be blank.  I am not very familiar / comfortable working with the concept of 'Range'.  Therefore, any sample codes would be greatly appreciated.  (I did try to google it, but the code snippets I found didn't quite do what I needed)</p>
  
  <p>Thank you.</p>
