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 complete single-user VFP applications which uses forms, reports and menus.

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.
  • High-performance queries via SQL.

Building the application

  • The structure of a VFP application.
  • Creating an event-driven user interface.
  • Working with the Form Designer.
  • Linking forms to data.
  • Getting the most from VFP's built-in controls.
  • Working with modeless forms and multiple instances.
  • Invoking Windows common dialogues.

Debugging tools and techniques

  • The VFP Debugger in depth: tracing code, monitoring variables, working with breakpoints.
  • 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.

Microsoft Certification

Between them, our Stage 2 and Stage 3 courses cover 80 percent of the requirements for Exam 70-156 (Visual Foxpro Desktop) and 70 percent of those for Exam 70-155 (Visual Foxpro Distributed). As a matter of policy, we no not use official Microsoft course material. All courses are taught by a Microsoft Certified Professional, qualified in Visual Foxpro.
