• High Level Languages
• Procedural
• Object Oriented
• Event-Driven
• Object Oriented Event Driven

4
Comparison of Programming Paradigms
5
Event Driven Applications

• Events are Fired / Code is written for Events
• Programs are More Interactive
• Multiple Input Points
• Program Waits for an Event
• Application is Driven by the User
• Events Occur in Sequence

6
Developing Event Driven Applications

• SDLC
• Feasibility Study
• Requirements Specifications
• Analysis

7
2 Types of VB Code

• Interface Related
• Event Procedures
• Fired when the Event Occurs
• Non-Interface Related
• User-Defined Procedures
• These Procedures must be called

8
Introduction to Objects

• Basic Element of the VB Program
• Forms
• Controls
• Properties
• Determine Appearance and Some Behavior
• Events
• Action the program can respond to
• Methods
• Pre-programmed code

9
Forms

• Nested Loops

23
Programming Fundamentals Input Validation

• Decision Statements
• Repetition Structures
• Validating Event

24
Testing Notes

• Variety of Test Questions Multiple Choice,
  Short Answer, Discussion, Coding
• Know Common Properties, Events, Methods for
  Common Controls (Used in Class, Labs, Programming
  Assignments)
• Partial Answers are better than no answers
• Pseudo-Code if necessary
• A Line of Code requires only a Line of Code
• An Event Procedure required Procedure
  Declarations (Header, End Sub)
• Practice Coding
• Practice Problem Solving If you dont solve the
  problem then the answer is wrong
• Questions Come from Class Discussions /
  PowerPoints / Textbook Chapters 1 - 5
