Thanks Jim et al

>Thoise classes (in FFC) are the foudnation calsses. Base classes are built into to VFP and cannot be modified, only subclassed. Unless you took some specific action to get your fomr to use your subclasses, then you are using the VFP baseclases, not the classes you think.

that settles that then...

>There are other ways to get VFP to use your classes. The tools-options dialog has a page titled Field Mapping. ON this page you can assign specific classes to the various data types. Also, in a databse you can assign a specific class to each field in a table.

I don't want to hear this but I guess that after you've already planted a few hundred textboxes around the place (all based on the vfp baseclass) its too late to go change the parent classes? (or is my fairy godmother watching and you can do this using the field mapping you speak of?
