1. An Introduction to Visual Basic
Terms & Concepts

2. What is VB?
Visual Basic is a programming language (actually an environment) designed to create computer programs that run in Microsoft Windows.
VB has been developed through many versions. This course uses VB 2008.

3. Getting Started VB 2008 addresses problem solving
“from the outside, in.”
In other words, the user interface is designed and created first, then its Events are programmed.

4. The Windows GUI
The Graphical User Interface (GUI) is the means through which users can interact with programs.
Each window is called a form.
Each form is populated with controls.
It is through these controls that the programmer handles I/O in VB.

5. The Windows GUI There are many different kinds of controls: Label
Text box
Radio button
Check box
Command button
Image
List box
Drop-down list
Frame
Line / Shape
Tab

7. Programming Language Paradigms
Recall the programming paradigms:
Procedural
Functional
Declarative
Object-oriented
Event-driven
In this paradigm we develop projects rather than programs.

8. Object Oriented Programming
A VB project consists of:
Objects - the nouns of OOP
forms and controls are examples of objects.
Properties - the adjectives
size, location, name, caption
Methods - the verbs
Move, Print, Resize, Clear
The dot operator
Object.property is the syntax for referring to a particular property of a particular object.
