Gotcha.

>Factory patterns can be useful. My dfHGrid class has properties that allow the floating shape to come from a user specified class/classlib.

This is a cool thing about VFP: you can instantiate a class from a string. Where you'd have to write a factory method in C++, you can just set a property in VFP.

Most of the time, the factory isn't a separate object--it's just an (overrideable) method that a class calls instead of instantiating objects directly.
