I use Codemine with Stonefield D/T. When I first started with Codemine, I wasn't using a "real" framework. I just subclassed the base classes and tweaked a few things. When I first got CM, it was a pain to convert to the new classes by browsing the SCX in VFP. Then I went to Whilfest and got (bought) a copy of HackCX. This let me change all the class definitions of my old apps and I never looked back. It was kind of like converting from FPDOS to VFP, but MUCH easier. I can't say enough about how easy CM is to use.

If you need anything further, please let me know.
