4. LESSON 1.1
OVERVIEW OF
VISUAL BASIC

5. What is Visual Basic?
Visual Basic is a third-generation event-driven
programming language and Integrated Development
Programming (IDE) first released by Microsoft in
1991 for its COM Programming Model . It evolved
from the earlier DOS version called
BASIC. BASIC means :-
Beginners’All Purpose Symbolic Instruction Code.

6. Since then, Microsoft has released many
versions of Visual Basic, from Visual Basic 1.0
to the final version Visual Basic 6.0. Visual
Basic is a user-friendly programming language
designed for beginners, and it enables anyone to
develop GUI window applications easily.

7. VB AS PROGRAMMING LANGUAGE
Visual Basic is a Programming tool that
allows user to develop Windows or GUI (
Graphical User Interface ) applications.
It means that rather than writing
numerous line for code to describe the
appearance and location for interface
elements like C , C + + or Basic.

8. VB AS PROGRAMMING LANGUAGE
User can simply drag and drop pre-built
objects into the form window on computer
screen. VB is a much enhance version of
BASIC programming language (BASIC is
Predecessor of VB). The main difference is
that the VB can create windows programs by
just Drag & Drop where as BASIC could only
create DOS programs or work only in CUI
(Command User Interface).

9. BRIEF HISTORY OF VISUAL BASIC
Alan Cooper (born June 3,
1952) is an American software
designer and programmer.
Widely recognized as the
"Father of Visual Basic“. He
developed Visual Basic in 1988
and sold to Microsoft.

Binary access file support.
10. Useful debugger and error handling
facilities.

17. Advantages of Visual Basic
A. The structure of the Basic programming
language is very simple, particularly as to
the executable code.
B. VB is not only a language but primarily
an integrated, interactive development
environment ("IDE").

18. Advantages of Visual Basic
C. The VB-IDE has been highly optimized to
support rapid application development ("RAD").
It is particularly easy to develop graphical user
interfaces and to connect them to handler
functions provided by the application.
D. VB is attuned to Microsoft’s Computer
Object Model(“COM”).

19. Advantages of Visual Basic
E. The graphical user interface of the VB-
IDE provides intuitively appealing views for
the management of the program structure in
the large and the various types of entities
(classes, modules, procedures, forms).

VISUAL BASIC
INTEGRATED DEVELOPMENT
ENVIRONMENT (IDE)

21. INTRODUCTION
IDE is a term commonly used in the programming
world to describe the interface and environment that
we use to create our applications. It is called integrated
because we can access virtually all of the development
tools that we need from one screen called an interface.
The IDE is also commonly referred to as the design
environment, or the program

22. INTERFACE OF VISUAL BASIC
When user start the window, it display a screen
having certain option. With the help of this
screen user can select the type of project user
want to make.
Visual Basic environment is platform provided by
VB to develop and execute a project . This
environment consist of different platforms or
control tools and various other options.

23. The Visual Basic Startup Dialog Box

24. The Visual Basic IDE
When user choose any application platform,
like any other window application, VB consists
of multiple window, which appear at start up.
The windows that are display when user start VB
are collectively Known as Visual basic
Integrated Development Environment ( IDE ).

25. The Visual Basic IDE
Project
Window
Properties
Window
Form Layout
Window
Form Window
Toolbox
Toolbar
Title bar
Menu bar
Visual Basic Integrated Development Environment

26. Title Bar - The top of the window with the name of the
project.
The Menu Bar - Displays the commands required to build
an application.
The Tool Bars - Provides shortcut icons for quick access to
the commonly used commands.

27. 4. PROPERTIES WINDOW
The Properties window let user to
change the characteristics, or property
settings, of the form itself and of visual
interface elements on the form. The
Properties window consists of two
columns: the first is the name of the
property, which user cannot change; the
second column, which is the property
setting that user can change. Any Change
in the property of the object will affect the
object on the form.

28. 5. TOOLBOX
The toolbox consists of the
various objects that user will use
to design the application. These
objects, called controls, are
objects that user see in all
standard Win applications, such
as textboxes, command buttons,
option (radio) buttons,
checkboxes, etc.

29. 6. FORM WINDOW
The Form window is the central
area where user can draw
application. The forms are
windows which holds control
like Button , Checkbox etc
which make user application.
The large area of form is called
client area for working with
different controls.

30. 7. SOURCE CODE WINDOW
The Source Code window is
where user type the code which
VB execute. It has two parts
Control Box , Event Box .The
Heading of window indicate
which event the code is
associated . It is a window
where user write most of the
code .

31. SOURCE CODE WINDOW
It shows the control Box which
contains two controls
( Command 1 & Form ).

32. SOURCE CODE WINDOW
It shows the Event Box that
Selected Control can perform
these event.

33. OPENING A PROJECT

39. LESSON 1.3
Introduction to Object-Oriented
Programming (OOP)

40. Visual Basic (VB) is an object-oriented programming
(OOP) language, which means it uses objects to model real-
world entities.
Key Concepts of OOP:
1. Class: A blueprint for creating objects.
2. Object: An instance of a class.
3. Modules: Containers for organizing code.
4. Events: Actions or occurrences that trigger code
execution.

41. CLASSES in Visual Basic
A class is a
user-defined
data type that
defines
properties,
methods, and
events..

42. CLASSES in Visual Basic

43. MODULES in Visual Basic
A module is a container for procedures,
variables, and functions that can be shared
across an application.
Purpose
1. Provide global scope to shared code.
2. Group related procedures and functions

44. MODULES in Visual Basic

45. EVENTS in Visual Basic
Events are actions or occurrences that an object can recognize
and respond to.
Common Events in VB.
Click: Triggered when a control (e.g., button) is clicked.
Load: Triggered when a form is loaded.
TextChanged: Triggered when the text of a control (e.g.,
textbox) changes.

46. EVENTS in Visual Basic

47. EXAMPLE: BUTTON CLICK EVENT
Private Sub Button1_Click(sender As Object, e As EventArgs)
Handles Button1.
Click MessageBox.Show("Button Clicked!")
End Sub

48. DATA TYPES SUPPORTED IN VB
Data types in Visual Basic specify the type of data a
variable can hold, ensuring proper memory allocation and
operation.
Importance:
Helps in efficient memory usage.
Ensures data integrity.
Prevents runtime errors.

49. DATE
STRING
BYTE
VARIANT
OBJECT
