UNIT III – Introduction to VISUAL BASIC
LESSON 1 The VB Development Environment
Visual Basic
A high level programming language
It is created by Microsoft
Uses a graphical environment called the Integrated Development Environment (IDE)
It is capable of developing Windows-based applications and games
An Event-driven language
A Visual Basic program is made up of many subprograms, each with its own codes that can run independently, and at the same time, can be linked together
COMMONLY USED TERMS
There are many technical terms that you will encounter as you go along studying Visual Basic. You must be very familiar with these terms to easily understand the instructions that will be given in the next lessons to come.
1. APPLICATION – collection of objects that works together to accomplish certain task/s for its users.
Examples: Microsoft Word, Adobe Photoshop, Corel Draw
2. PROJECT – the term used in Visual Basic pertaining to Application.
Examples: Payroll System, Quiz Bee Scoring Program
3. OBJECT – a piece of software that has properties and functions that can be managed or controlled.
Examples: a window, dialog box
4. PROPERTY – characteristics of an Object.
Examples: color, size, background
5. METHODS – functions of an Object that can be manipulated.
Examples: opening, resizing, moving (of a window)
6. OBJECT-ORIENTED ENVIRONMENT – a place wherein application is created using objects and combining them to produce an output.
Examples: Visual Basic Environment, Visual Studio Environment
7. EVENT – an action that happens when a message is triggered such as
Examples: clicking of a button, clicking of a menu, loading of form
8. EVENT-DRIVEN – an operation is executed as the result of some kind of event.
9. FORM – the first object you will see on the screen when you open Visual Basic. It is where all the controls are placed. It is also where you will enter data and see the results.
10. CONTROLS – the objects you put on a form.
Examples: textbox, label, command button
