>Sorry, I wasn't meaning to upset anyone. Did I say something wrong..like VB?? It's my most obvious comparison coz I've used it for so long...don't get me wrong I'm beginning to like VFP and I'm not about to say that VB is wonderful when it quite patently isn't (don't mention grids!).

I am not upset when somebody mentions VB, which I don't know well. I just wanted to clarify what was, in my opinion, Microsoft's priority when improving FoxPro.

>It's funny you should mention previous versions of FoxPro..I'm amazed at how much FoxPro 2.x stuff is still in service. I suppose if it works OK then no need to fix it. Anyway, I thought MS's first priority was to rip off Rushmore???

While MS used Rushmore in other products, instead of buying FoxPro, they could easily have created a similar technology, with a different name.

Rushmore allows for fast data access, sometimes; but it is actually quite primitive compared with the optimization techniques used by database servers (do a search in relevant places, perhaps www.pcwebopedia.com or www.whatis.com, for "cost-based optimization"). Rushmore Optimization uses any existing index to optimize a query. In some cases this makes queries faster, in some cases, slower! See my FAQ #8109, on Rushmore Optimization.

Rule-based optimization on a client server, or, better yet, cost-based optimization, OTOH, will use a more efficient algorithm.

>Dunno if that's true or not..it's just that Access got remarkably faster from version 1.x to 2.x.

Yes, I understand Access incorporated R.O.; that must have helped. R.O. is usually fast, despite my comments above.

>MS has had FoxPro for six years or so and it just seems odd that there's some nice stuff in VB that VFP aint got and some nice stuff in VFP that VB aint got.

If there are some features you miss a lot, there is often a workaround. However, you can also add comments to the Toledo Wishlist. Perhaps MS will one day incorporate your favorite wish.

Hilmar.
