Like what. I'm not aware of anything major that has been broken in VFP8 ?

There is a signficant bug with the group by clause. Somehow - something that had been working for a long time managed to break in 8. Also, I have encountered a number of C5 errors when XP theme support is on. I'll leave it to you to search the numerous posts that have been made here.

The view designer does not have anything to do with the cursor adapter class. I'm not sure what you're telling me here. There are a number of improvements in the View designer:

You have always been able to define views with more complex sql in such a way that would render the view designer moot. You can't say there is a true 2-way tool unless you could define ANYTHING in text - and have it rendered graphically.

SQL views work with SQL update or SQL Delete and SQL insert. With the cursor adapter you can use anything you want.

Somewhat gets to my point about cursoradapater - which is kind of like the remote views slightly more sophisticated cousin.

From your reaction I get the impression that you don't have a clue about the improvements in the VFP8 view designer. I get the impression that you don't know what you're talking about.

That may be your impression - but the facts would indicate otherwise. The fact that you clasify the view designer as a true "2 way tool" - I could say the same thing to you. The fact is - the objectional issues that I have articulated about RV's are still applicable today. I have had to deal with RV's extensively. That said - I have used other data access methodoligies extensively. I have had the opportunity to use, evaluate, and compare the various methodologies. While RV's can "work" - but nonetheless - they are inferior to other methodologies out there. Like anything - indvidual milage may vary. That said - when you look at both sides of the ledger - when you look at the big picture - there are far more reasons to eschew RV's than to embrace them. There are 100's of posts over the past 5 years or so from me on the topic. There is no need for me to enumerate those reasons again.
