HISTORY OF VISUAL BASIC

HISTORY OF VISUAL BASIC

VB 1.0 was introduced in 1991. The drag and drop design for

creating the user interface is derived from a prototype form

generator developed by Alan Cooper and his company called

Tripod. Microsoft contracted with Cooper and his associates to

develop Tripod into a programmable form system for Windows

3.0, under the code name Ruby.

Tripod did not include a programming language at all. Microsoft

decided to combine Ruby with the Basic language to create Visual

Basic.

The Ruby interface generator provided the "visual" part of Visual

Basic and this was combined with the "EB" Embedded BASIC

engine designed for Microsoft's abandoned "Omega" database

system. Ruby also provided the ability to load dynamic link

9

libraries containing additional controls (then called "gizmos"),

which later became the VBX interface

Visual Basic (VB) is the third-generation event-driven

programming language and integrated development environment

(IDE) from Microsoft for its COM programming model. Visual

Basic is relatively easy to learn and use.

Visual Basic was derived from BASIC and enables the

rapid application development (RAD) of graphical user interface

(GUI) applications, access to databases using Data Access Objects,

Remote Data Objects, or ActiveX Data Objects, and creation of

ActiveX controls and objects.

Scripting languages such as VBA and VBScript are syntactically

similar to Visual Basic, but perform differently.

A programmer can put together an application using the

components provided with Visual Basic itself. Programs written in

Visual Basic can also use the Windows API, but doing so requires

external function declarations.

Visual Basic is a "visual programming" environment for developing

Windows (also Web now) applications. Visual Basic makes it

possible to develop complicated applications very quickly. The

10

programmer designs windows graphically, drags program elements

from the Visual Basic Toolbox and writes basic code for each

element. Visual Basic is "event-driven" which means that procedures

are called automatically when the end user chooses menu items,

clicks the mouse, moves objects on the screen, etc.

CHARACTERSTICS OF VISUAL BASIC

11

CHARACTERSTICS OF VISUAL BASIC

VISUAL BASIC is a high level programming language which

evolved from the earlier DOS version called BASIC. BASIC means

Beginners' All-purpose Symbolic Instruction Code. It is a very easy

programming language to learn. The code look a lot like English

Language. Different software companies produced different versions

of BASIC, such as Microsoft QBASIC, QUICKBASIC,

GWBASIC ,IBM BASICA and so on. However, people prefer to use

12

Microsoft Visual Basic today, as it is a well developed programming

language and supporting resources are available everywhere. Now,

there are many versions of VB exist in the market, the most popular

one and still widely used by many VB programmers is none other

than Visual Basic 6. We also have VB.net, VB2005, VB2008 and the

latest VB2010. Both Vb2008 and VB2010 are fully object oriented

programming (OOP) language.

VISUAL BASIC is a VISUAL and events driven Programming

Language. These are the main divergence from the old BASIC. In

BASIC, programming is done in a text-only environment and the

program is executed sequentially. In VB, programming is done in a

graphical environment. In the old BASIC, you have to write

program code for each graphical object you wish to display it on

screen, including its position and its color. However, In VB , you

just need to drag and drop any graphical object anywhere on the

form, and you can change its color any time using the properties

windows.

On the other hand, because the user may click on a certain object

randomly, so each object has to be programmed independently to

be able to response to those actions (events). Therefore, a VB

Program is made up of many subprograms, each has its own

13

program code, and each can be executed independently and at the

same time each can be linked together in one way or another.

Like the BASIC programming language, Visual Basic was designed

to be easily learned and used by beginner programmers. The

language not only allows programmers to create simple GUI

applications, but can also develop complex applications.

Programming in VB is a combination of visually arranging

components or controls on a form, specifying attributes and actions

of those components, and writing additional lines of code for more

functionality. Since default attributes and actions are defined for the

components, a simple program can be created without the

programmer having to write many lines of code. Performance

problems were experienced by earlier versions, but with faster

computers and native code compilation this has become less of an

issue.

Forms are created using drag-and-drop techniques. A tool is used

to place controls (e.g., text boxes, buttons, etc.) on the form

(window). Controls have attributes and event handlers associated

with them. Default values are provided when the control is created,

http://en.wikipedia.org/wiki/GUI_widget

http://en.wikipedia.org/wiki/GUI_widget

http://en.wikipedia.org/wiki/Graphical_user_interface

http://en.wikipedia.org/wiki/BASIC

but may be changed by the programmer. Many attribute values can

be modified during run time based on user actions or changes in

the environment, providing a dynamic application. For example,

code can be inserted into the form resize event handler to

reposition a control so that it remains centered on the form,

expands to fill up the form, etc. By inserting code into the event

handler for a keypress in a text box, the program can automatically

translate the case of the text being entered, or even prevent certain

characters from being inserted.

Visual Basic can create executables (EXE files), ActiveX controls,

or DLL files, but is primarily used to develop Windows

applications and to interface database systems. Dialog boxes with

less functionality can be used to provide pop-up capabilities.

Controls provide the basic functionality of the application, while

programmers can insert additional logic within the appropriate

event handlers. For example, a drop-down combination box will

automatically display its list and allow the user to select any

element. An event handler is called when an item is selected,

which can then execute additional code created by the programmer

to perform some action based on which element was selected, such

as populating a related list.

2.) SYSTEM DEVELOPMENT

26

2.1) Initial investigation


2.) SYSTEM DEVELOPMENT

2.1) Initial investigation:

27

There is a system, which is concerned with the student and

their Information that is service and maintaining the record of the

students.

In this system the data, which is about the student , maintaining

on the paper that is this system is based on paperwork.

We will define a transaction as the occurrence due to which the

current state of the system changes. It means that some updating of

data or the information changes.

The problems in paper –based system were:

1) slow and error prone data entry

2) Difficulties in data retrieval

3) Difficulties to manage a long record

4) Calculations are made by human; therefore there

is less accuracy in data transaction calculations.

28


The existing system can be replaced by computer-

based system, which can perform all the related tasks

of business in a better and efficient way. The

alternative computer based system can provide many

facilities over present paper based system in the

following manner.

1) The data entry in a new computer based system will be fast

2) Easy and fast data retrieval

3) Long records can be managed easily

4) Computer does calculations, which improve accuracy.

3.) SYSTEM ANALYSIS

3.1) What is the problem?

In this way we realize that the new system is required

and will certainly improve the performance of the

exiting system over the exiting paper based system.

1. Design the system to develop the alternative

computer based system

2. To understand the user characteristics

31

3. Design a system for a particular types of

user

3.1.2) Information about student:

There is the following information required to store for

student

3.2) Feasibility Study:

Feasibility study is the most important work of an analyst

in which the opportunities of problem solving are considered and

it is mainly considered that the problem is solved for the

organization or not. Following feasibility analysis of our system

are given below

32

3.2.1) Technical Feasibility:

The key question of the technical feasibility is “can the

work for the project be done with current equipment, exiting

software technology, and available personnel? If new technology

is required, what is the likelihood that it can be developed?

Our system requirement in the direction of technical

feasibility is feasible as per following:

1) Our system in run for a single user and it require no

more knowledge about computer system and it can

be run by the user with having small knowledge of

computer.

2) Our front end of the computer system is visual Basic

which is free of cost and sufficient to provide the

user friendly environment.

33

3) For the back end of computer system as database

Microsoft access is chosen that is not free of cost but

it is fit in the expenditure of the origination and it can

sufficiently manage the database in very efficiently

and fast way.

3.2.2) Economical Feasibility:

The key question of the economical feasibility is ”Are

there sufficient benefits In creating the system to make the costs

acceptable? Are the cost of not creating the system so that the

project must be undertaken?”

Our system requirements in the direction of economical

feasibility are feasible as per following:

34

2) Our system is developed in the Visual Basic

which is a free source and available for

everyone.

3) The back end used in our system is Microsoft

Access that is not free of cost but it is fit in the

expenditure of the organization.

3.2.3) Operational Feasibility:

The key question of the operational feasibility

is “Will the system be used if it is developed and

implemented? Will there be resistance from users

that will undermine the possible application

benefits?”

Our system requirements in the direction of

operational feasibility are feasible as per following:

35

1) The present system is paper based which have a

lot of problems which can be overcome by

replacing it by our new system and work with it

2) There may be some problems in the system

faced by the user can communicate with the

origination to inform the difficulties which will

be solved immediately.

3.3) System Interfaces:

3.3.1) User Interface:

The Library is the system developed for the students

to Providing the information’s. It is a multi user system these

are the owner and other workers. The user interface to the

36

system is very easy, as it will be implemented by easy software,

which can be used effectively, and efficiently.

3.3.2 Hardware Interface:

Min. (64) MB RAM

Key Board

Mouse

3.3.3 Software Interface:

Visual Basic 6.0

Microsoft Access used as back –end to store the

database.

3.3.4 Communication Interface:

Verbal communication takes place between the

system user (student) and student of the Library. The

communication of user to the computer system will be

very easy and user will get correct information. Student

37

will not directly communicate with the computer system

but he/she will feel the effect of the computer

System over existing paper-based system, as it

will provide fast processing and accurate calculations.

3.3.5 Memory Constraints:

Min. (64) MB RAM

Min. 70 KB free hard disk

3.4 Problem Statement:

This the very first phase of project development in this

phase the user provides his requirements in the form of a

problem statement specifying the features of required system.

Problem statement of our project is as follows:

Design a system that will automate the transaction

processing. This system will be used by single user of the

38

Library information and this should provide for the entries of

new student as well as keeping track of what service has been

given to student and which of them are available. This system

should provide measures for maintaining the security and should

be easy to use. The sole user of the system will also enter records

for the students and their information.

3.5) Object Modeling:

Object modeling is done by to handle the real life

problems in which object and classes are mainly

emphasized. We insist upon what is being affected rather

than what is being done.

There are three phases of object modeling:

1) Object Modeling

2) Dynamic modeling

3) Functional Modeling

39

3.5.1) Object Modeling:

Object modeling is done to find all the objects and

relation among them like (association, generalization

etc.)

A) OBJECTS OF THE SYSTEM

There are several objects of our system, which are

given below after refining them and removing all

other unnecessary objects. Library, Owner, Students,

Service, traction etc are our main objects of the

system.

B) FINDING THE ASSOCIATIONS:

Following associations are found in this system.

Student goes to Library

40

Library floor has an owner ( they may be only one)

Student requests for the service to the owner

Owner asks information from the Student.

Owner issues the service.

Library contains the record of the services provided to the

Student.

Transaction updates the record.

Owner initiates the transaction.

Student returns the issues the books.

Owner clears the record.

3.6) Dynamic Model:

Dynamic model show the time dependent behavior of

the system and the objects in it. We begin dynamic analysis

41

by looking for events external stimuli and responses. The

dynamic model is important for interactive systems.

Steps taken in dynamic modeling are:

Prepare scenarios of typical interaction sequences

Identify events between objects

Prepare an events trace for each scenario

Build a state diagram match events between objects to verify

consistency

A state is an abstraction of the attribute value and links of an

object. A state specifies the response of the object to input events. A

state corresponds to the interval between two events received by an

object. Events represents interval of time. A state has duration; it

occupies an interval of time. A state is often associated with a

continuous activity.

42

A state diagram is graph whose nodes are states and whose

directed arcs are transitions leveled by event names. A state is draw

as a round box containing an optional name. a transaction is draw as

an arrow from the receiving state to the target state.
