Remarks

To use, drop the class on a project or form 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 icon on the form. You can then specify the appropriate property values and access its functionality from input and output objects. 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 Classes for more information on using foundation classes.
