I seem to get asked more and more questions from my ISVs around "when will Microsoft stop supporting ..."

I have just the site for you http://support.microsoft.com/lifecycle/

e.g.
Visual Basic http://support.microsoft.com/lifecycle/search/?sort=PN&alpha=Visual+Basic
MSDE http://support.microsoft.com/lifecycle/search/?sort=PN&alpha=desktop+engine

And while I am on the subject - Visual Basic 6 Development Environment will not be supported on Windows Vista (FYI - on Beta 2 I can not install the latest SP for VB6). Check out http://www.devsource.com/article2/0,1895,1929552,00.asp
