Remarks
This class provides access to information in the Windows Registry.
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 on the form. You can then specify the appropriate property values and provide any necessary 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.
