Hi Kamal ---

>Ken had been using this extensively at his demos at Devcon. For e.g. say you have a class Foo, which has properties p1 and p2.

I haven't been able to go to any DevCons in a while so I miss out on stuff like that. I saw a similar demo in Solutions app which ships with VFP. Again, it's not that I don't know what to do with it in theory, it's that I have not practically applied it in code.

I can think of a COM compliant use. If you have a new COM DLL that replaces an old one, you can use THIS_ACCESS I suppose to rerout property calls to newer methods. I know that, technically, you are never supposed to delete old interfaces in COM theory, but I wonder if it counts if you trap them and re-rout them.
