Remarks

This class uses the TlbInf32 COM component to read type information from type libraries. The main routine ExportTypeLib creates a text file with Type library output.

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 project, you can choose between adding the class or creating a subclass. 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 on the form in the Form Designer.

See Guidelines for Using Visual FoxPro Foundation Classes for more information on using foundation classes.
