>Thank you, Nadya. As I recall, you asked me recently what was wrong with Ed's approach and I said that there wasn't anything wrong with it. If you like, you can read the MS KB article I mentioned in my post to Larry on this subject. While the article didn't exist when I originally wrote mine for FPA, other documentation covering this did. So you can see the source of my work if you want to.

I will, thanks.
