8279 BTec Nationals Unit 20 Event Driven Programming

Next Session Session 1

Learning outcomes
On completion of this unit a learner should:
1 Understand the characteristics and uses of event driven programming
2 Be able to use the tools and techniques of an event driven language
3 Be able to design and create an event driven application
4 Be able to test and review an event driven application.

1 Understand the characteristics and uses of event driven programming
Key characteristics: eg event handlers; trigger functions; event loops; forms
Advantages of event driven programming: flexibility; suitability for graphical interfaces; simplicity of programming; ease of development
Disadvantages: eg can be slow
Examples: operating systems as event driven systems; GUIs
Programming languages: eg VB, VB.NET, Visual C++, VBA

2 Be able to use the tools and techniques of an event driven language
Triggers: eg key press, alarm, system event, touch screen event, mouse click
Tools and techniques: eg use of tool boxes and controls, selection, loops, event handlers, triggers, objects and object properties, menus; debugging tools
Data: variables; data types; declaring variables; scope of variables; constants

3 Be able to design and create an event driven application
Specification: input; output; processes; user need; purpose
Design: screen layouts; data storage; event procedures and descriptions; appropriate ways of representing the processing tasks
Creation of application: use of development environment; debugging

4 Be able to test and review an event driven application
Testing and debugging: test strategy; test plan structure eg test, date, expected result, actual result, corrective action; error messages; specialist software tools
eg debug
Review: against specifications requirements; interim reviews
