Thanks. Could u give me a verbal description of what would be the contents of the bizobj for 'Customer' or 'Musician' and how would UI controls be 'associated' with the bizobj. I am comfortable with the concept of OOP but get stymied at the implementation stage.

'Enhanced Bizobj' means enhanced as per MMdoc ver2.o or is that not sufficient ?

Hope you dont mind my questions - i am trying very hard to understand this. Thanks, once again

>Many developers have a tough time with this concept initially as with any OOP abstraction. It's hard to make the mental leap between a real-world object such as an Invoice to a VFP Class that represents the characteristics and functionality of an Invoice. I recommend Savannah Brentnall's "Object Orientation in Visual FoxPro" (Addison Wesley - ISBN 0-201-47943-5) for developers who are climbing the VFP OOP learning curve. It really helps solidify many of these concepts.

Would i need to modify any of the classes to handle pageframes ? Or will the CB3 modified as per MMdoc Ver 2 take care of this automatically ?

>Oops! This is a paragraph that I should have taken out long ago. When using the original VFP3 Codebook's old style business objects, this was the suggested method. However, with the newly enhanced business objects, this is no longer true...and as I stated previously, I don't recommend binding user interface controls to the business object; just drop the business object on the form and then drop the associated user interface controls on the form.
