In an earlier post today http://www.vbforums.com/showthread.php?t=663054 jmcilhinney in post #9 says,
If you're going to use a DataSet at all then there's no reason not to use a typed DataSet. I would not recommend dragging items from the Data Sources window directly onto a form but that is not a requirement of using a Data Source.
I was wondering what is the down side of dragging items onto the form. I don't mind doing the manual programming, I would just like to know the reason I'm doing it.

Thanks for any replies
