Don't forget "Oop is not as easy as its looks like'.

These are some of my learning experience:
1. If you will use many forms, please use formset.
2. You can read some books which are about 'Oop'. 'Oop' is a concept which is not only used in Vfp. If you have clear concept on it, will help you to develop Vfp program. There are many oop books in Hong Kong Libraries. For you I think Grady Booch's books is a good choice. He/She was one of the developers on developing oop & ood(object oriented design).
3. Use 'this' property as many as possible.
4. Abstracts data/object as small as possible. (Data abstraction is one of the benefit in using oop)
5. Remember the 'fire squence'. It can help you to decide which object you should use.
