VISUAL FOXPRO STAGE 2: Five Days

A hands-on course for developers who have already had some exposure to VFP or experience of other XBase languages.

This course will teach you how to create well-structured Visual Foxpro applications using the full repertoire of Windows controls. The emphasis is on re-usability and productivity through object-oriented programming (OOP). We take an intensely practical approach to OOP, with real-world techniques favored over abstract theory.

WHAT YOU WILL ACHIEVE

At the end of the course, delegates who meet the pre-requisites will be able to create, debug and deploy sophisticated data-based event-driven business applications using sound object-oriented techniques.

PRE-REQUISITES

To benefit from the course, you should either:

  • Have experience of Foxpro for Windows, Foxpro for DOS, Foxbase, Clipper or another XBase dialect, or

  • Have some previous exposure to Visual Foxpro and be familiar with the basics of the VFP language.

You do not need previous knowledge of object-oriented programming.

COURSE CONTENTS

Using OOP to create re-usable components
  • Introduction to OOP terminology and concepts.
  • Practical examples of OOP.
  • Designing generic controls for portability and re-usability.
  • Sub-classing and inheritance; converting existing controls into classes.
  • Managing class libraries; the Class Browser.

Database container, queries and buffering
  • Understanding persistent relationships, database properties, triggers and stored procedures.
  • Using buffers to protect your data.
  • Maintaining data integrity; the RI Builder.
  • Multi-user issues: optimistic and pessimistic locking; dealing with conflicts.

  • Further debugging techniques: assertions, event tracking, coverage analysis.

Deploying the application
  • Creating executable programs.
  • Using InstallShield Express or the VFP Setup Wizard to simplify distribution; installing the application at the user's site.

More tools and techniques
  • Using collections to make code more generic.
  • SQL in depth.
  • Time-saving tricks, tips and shortcuts.
