It is a shame we did not get it this time around. Once again, the priorities were in the middle tier. Not that I agree with that... it just the way things are. I also don't think the VFP folks to what extent the dev. community would gravitate to ADO.

Internet apps are a completely different issue. I can't see converting ADO recordsets to VFP cursors practical at all in an Internet app. My comments where in the context of being outside the internet/web.

Yes, ADO will be slower than VFP - you won't get an argument from me. However, once you do stuff across a WAN or need a C/S architecture, ADO will smoke VFP as VFP is file/server based.

Would it help to say that I have actually sat down with members of the team??

OK, I see your point here.

>God help us, then. 8-)

I don't disagree with you here<g>.

Other UI's IMO, like IE/DHTML and VB show a lot of promise. These are tools that can be used today - without us having to wait for things to get implemented in VFP.

Have you used RDS? Working with images is nice, but what about data???

Yes, you encouraged folks to look at VJ and a Supercede
