Remarks
This subclass of the Microsoft Internet Explorer browser control provides hooks for Visual FoxPro code and can be added to a Visual FoxPro form.
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 an Internet Explorer logo on your form. You need to specify an appropriate URL in the Navigate method. 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.
