Delphi Component Creation

The Delphi Component Creation course is designed for programmers with a good working knowledge of Delphi. The course provides a comprehensive coverage of component creation essentials including Object Oriented Programming, understanding and using Packages and Windows Messages and builds on this groundwork to explore every aspect of component creation. The component examples and component exercises are based on useful components which you will want to use in your own development.

This course is hands-on with practical exercises throughout. We provide you with individual PC's so that you are able to work on your own. Class sizes are kept small so that you will receive personal attention. You will take away extensive printed and disk-based course material, which will be of ongoing use to you in your work.
