I'm upgrading some projects to VB.NET (heavy sigh) and (among hundreds of
other problems) I can't seem to continue usage of the "Activate" method for
an Excel worksheet:

'Activate' is ambiguous across the inherited interfaces 'Excel._Worksheet'
and 'Excel.DocEvents_Event'

The worksheet object is declared as:

Dim objWorksheet As Excel.Worksheet

but "objWorksheet.Activate" seems to be a problem. I'm referencing the Excel
9.0 object library.

Any ideas?
