Remarks

The Offline switch works in a database containing remote views. This class provides a set of buttons that toggle between use of online and offline data.

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 Classes for more information on using foundation classes.
