Thanks for the link.

However as I mentioned, when I used the VFPToolkit, as it has also been mentioned in the article you linked, the framework classes were "sealed". It is only now in 3.5 that they have been unsealed. So at that time it made sense to use pre coded classes rather than write your own.
