> Pre-Requisites
Before attending this course, students should have the following pre-requisites:
  • A familiarity with Windows and database concepts.
> Purpose
The course introduces the key features and functionality of Visual FoxPro code with an emphasis on the rapid implementation of a database application. This course uses code rather than the Visual Design Tools to give a thorough preparation for Course F1013. During the course the delegate will use a broad range of VFP commands and functions, with a view to writing efficient reusable code. Course contents may alter slightly from those stated.
