Overview of Programming
The Structure and Operation of a Computer
 Computer system: hardware and software
 Processor (registers, primitive operations)
 Main memory (RAM, ROM)
 Data types (integers, real, floating-point
numbers, strings, etc.)
 Sequence and Data Control
 Storage management
 Operating environment

Object Technology



January 10, 2005
Objects are essentially reusable
software components that model items
in the real world, such as windows
cars, vehicles, and so on
Object technology is a packaging
scheme that enables programmers to
create meaningful software units.
Object-Oriented Programming tends
to produce software that is more
understandable, better organized, and
easier to maintain, modify and debug.

Object Model

Object ==> Noun
• Form and Controls

Property ==> Adjective
• Color of a Form

Method ==> Verb
• Move a Form

Event ==> Occurs when the user takes an action
• User clicks a button, User moves a form

Class ==> Template to create new object
• Each control added is an Instance of a Class

Dot Notation

Used to reference object's properties and
events in code
• Object dot Property

Form.Text, TextBox.Text
• Object dot Event


Form.Hide( ), TextBox.Focus( )
To reference an object's events use an
underscore instead of a dot

January 10, 2005
Button_Click, ListBox_TextChanged

Object Model Analogy





Class = automobile
Properties = make, model, color, year
Object = each individual car
• Object is also an Instance of the automobile
class
Methods = start, stop, speedup, slowdown
Events = car arrives, car crashes

Visual Basic .NET Programming

Learning Visual Basic.NET Programming
Language includes to learn:
• The graphical user interface or GUI
(“gooey”) which is an essential
component of visual programming

The GUI defines how various elements
look and function
• Visual Basic programming language

VB.NET Program Development

To create a VB.NET program you will utilize
the Visual Basic .NET 2005 development
environment, and you will
• create a window, called form
• select elements, which are classes, from a
toolbox and place them within the window,
called controls
• write code for each object that you place
on the window that defines how the object
responds to various events, called objectoriented programming (OOP).

16
Event-Driven Programming

The style of Execution as shown below is
called event-driven:
• A GUI determines how a user interacts with
the program
• Each user interaction with the computer:
pressing a key, clicking a button, or selecting
a menu item causes an event to occur
• Whenever an event occurs, the code you
have written to handle that event is executed

VB.NET Object Oriented
Programming


Using the VB.NET OOP Technology to work
with objects and develop an event-driven
program.
Each object consists of:
• Classes: Forms, Labels, Buttons, etc
• Objects: A particular Form, Label, Button, etc.
• Properties (attributes of an object): The Name
of a form, the Text in a Label, etc.
• Methods (the actions that an object performs
in response to GUI events): Close, Show,
Clear, etc.
• Event: when a user takes an action

About Visual Studio .NET
Framework

Visual Studio .NET 2005 includes:
• Visual Basic, Visual C++, C#, J#, and the .NET
framework.
• The .NET framework allowing objects from
different languages to operate together
• The .NET languages-based programs all compile
to a common machine language, called
Microsoft Intermediate Language (MSIL)
• The MSIL code runs in the Common Language
Runtime (CLR), which is part of the file .NET
framework.

About Visual Basic .NET
Framework


Visual Basic .NET 2005 provide:
• Object-Oriented Programming (OOP) solutions
and with increased object-oriented capabilities
• allowing for easier development of Web-based
applications
• interoperability with other languages
Major changes (to VB . NET) have been made, both
to the language syntax and the way that data are
stored and referenced

VB.NET Program
Development Process


Planning (design)
• design the GUI (user interface)
• list the objects and properties needed
• plan the event procedures (what the code does)
Programming (implementation)
• define the GUI using objects (Forms, Text Boxes,
Labels, etc.
• set the properties
• write BASIC code to implement procedures

VB.NET Application Files

Each Visual Basic application create the following
files with extensions:
• .sln - a solution file that holds information about
the project. This is the only file that is opened
• .suo - a solution user options file that stores
information about the selected options
• .vb - a .vb file that holds the definition of a form
• .resx - a resource file for the form
• .vbproj - a project file that describes the project
and lists the files are included
• .vbproj.user - a project user option file that
holds project option settings
