Anyway, now that I've really gotten to like intellisense, I'd like to make it work with my custom classes. I found out how to add one class at a time to it, but that's really tedious. Is there an easy way to add all of them at once?

If You ever worked with CEE under Fox 2.x to VFP 6, You will love my CEEClone. Even if not it's definitely worth a try. You can easily write small scripts. CEEClone works together with Intellisense so it's not one or the other.

What exactely is it that You want to do?
