Example 1

   Sub GetGraphTitle()

     ' Used for error trapping.
     On Error Resume Next

     ' Clear the error object.

     ' A reference to an object.

      ' A run-time error is generated if the selection is not an OLE
      ' object. This code traps the run-time error and prevents it from
      ' appearing.
