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 drop the class on a project, you can choose between adding the class or creating a subclass. When you choose an option from the shortcut menu or drop the class on a form, Visual FoxPro opens a builder so you can specify appropriate cFileName, lAutoOpen, lAutoPlay, lAutoRepeat, and cControlSource values.
