Introduction to Delphi

Overview

Introduction to Delphi Programming is designed for the student who wants to learn to develop Windows applications using the Delphi product from Inprise Corporation (formerly Borland).

This course introduces Delphi's integrated development environment. Applications are built using forms, components, and event-based programming in Delphi's Object Pascal programming language.

Object Pascal is presented in detail, so students will become familiar with the language's statements, declarations, data types, procedures, functions, and object-oriented features.

The average amount of time to complete the on-line materials is 14 to 16 hours.

Objectives

Upon successful conclusion of the course, the student should be able to:

• Introduce students to Delphi's integrated development environment
• Describe the basics of Delphi application development, using forms, components and event-based programming
• Present Delphi's Object Pascal programming language

Note: Students should come in with exposure to at least one programming language.
