>If that is not an acurate description of what I'm missing, then I guess I'll just have to accept the idea that it's over my head.

Concrete sample:

I define a class to draw chart, this class was based on custom class.
In this class I put a method: drawchart(), this method is empty at this stage.
From this class I subclass a BarChart class, and I put code on the DrawChart method to draw a Bar chart.
From the same base class, I subclass a PieChart class, and I put code in the DrawChart method to draw Pie chart.
I can define a lot of differents charts that use the same drawchart method.

Of course, if I want to use a button to close a form, I can start from VFP Button class and put a "thisform.release()" directly in the click of the button.

I think there is no absolute solutions for this, its all depend on the problem at hand when you start coding.

There is always be a lot of ways to skin a fox :-)
