Course Overview

This three-day course builds on the skills developed in the GBVFP 6101 course. The student will expand their knowledge of the Visual FoxPro tools and language to design and develop event-driven applications. The student will learn how to work with the properties, methods and events of all the form controls including the new Hyperlink control. Object-Oriented Programming (OOP) concepts and techniques are introduced in this course including the new Access and Assign methods. The student will learn how to apply OOP principles in Visual FoxPro by building classes, subclasses and working with the Class Browser and Component Gallery. Specific classes covered will include a number of Visual FoxPro's new Internet, data navigation, and utility classes. The student will receive a basic application framework and will learn how to distribute runtime versions of an application. Upon completion of the course, the student will keep the course materials and will receive a diskette containing all the course examples and exercises.
