The Visual Basic programming language was developed by Alan Cooper, an American scientist in the late 1980’

This programming language was created with the main purpose of teaching programmers and developers how to design graphical-user interface (GUI) programs easily.

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

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.

04/08/23 Mr. Roger C. Argarin 9

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

04/08/23 Mr. Roger C. Argarin 10

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

Button_Click, ListBox_TextChanged

04/08/23 Mr. Roger C. Argarin 11

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

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 languageMicrosoft Developers Network Homepage for VB.NET:

Label

GroupBox

RadioButtons

TextBox

PictureBox

Buttons

Form

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 object-oriented programming (OOP).

04/08/23 Mr. Roger C. Argarin 15

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

04/08/23 Mr. Roger C. Argarin 16

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.

04/08/23 Mr. Roger C. Argarin 17

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

04/08/23 Mr. Roger C. Argarin 18

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

The Microsoft VS Development Environment is also called integrated development environment (IDE): A form designer A code editor A compiler A debugger An object browser

Menu bar – includes file, edit, view, project, build, debug, data, format, tools, window, and help menu

Toolbar - includes many buttons as shortcuts for frequently used operations. Each button represents a command that can be selected from a menu. Most toolbars’ buttons are displayed in the main window of the IDE

•The properties window allows you to see and set all of the properties of the particular object that you have placed on the form. There are many properties for each object, and all can be seen by scrolling down the properties window.
