Hi Dan,

I bought my first DBI control back in 1997. I bought the Solutions:PIM for the scheduling control after spending around 500 man hours building an Outlook Clone control in pure VFP only to learn that when adding more than 150 to 200+ container objects (appointments) onto my VFP Schedule Container, it crawled. It was so slow that you could actually watch the lines painting across the screen. I mean really SLOW! Things have improved in 7 and 8 but still not to the point that you can write visual intense interfaces in VFP. That is why I build my graphically challenged controls as ActiveX controls using Delphi. There are few tricks to making Delphi ActiveX controls behave well in VFP but not that many. However, VFP still has it's own issues when supporting ActiveX controls. My controls will work great in VB without too much work but more work is required for good VFP integration. VFP does not track Focus very well. Since it doesn't use real Windows Controls, clicking into a text box doesn't cause focus to return to VFP all the time. However, in VB it works great.
