Remarks
To use, drop the class on a project or form in a data environment or, from the Component Gallery Item shortcut menu, select Add to Project or Add to Form. When you add the class to a form, Visual FoxPro places the class buttons on the form, and opens a builder so you can specify lUseCurrentDBC, lAllViews, lUpdateViews, and lRevertOnFail values. When you drop the class on a project, you can choose between adding the class or creating a subclass.
See Guidelines for Using Visual FoxPro Foundation Classesfor more information on using foundation classes.
