ACKNOWLEDGEMENT

It is not until you undertake the project like this one that you realize how

massive the effort it really is, or how much you must rely upon the Selfless

efforts and goodwill of others. There are many who helped us with this

project, and we want to thank them all from the core of our Hearts.

We owe special words of thanks to our Teachers Mr. pankaj for their

vision, thoughtful counseling and encouragement at every step of the

project. We are also thankful to the teachers of the Department for givingus the best of knowledge and guidance throughout the project.

And last but not the least, we find no words to acknowledge the financial

assistance & moral support rendered by our parents in making the effort a

success. All this has become reality because of their blessings and above

all by the grace of god.

INTRODUCTION:

We have discussed so far various features of V.B.NET and are ready to

write and execute program of modest complexity. However, before

attempting to develop complex programs, it is worthwhile to consider some

programming techniques that would help design efficient and error free.

The program development process includes three important stages, namely,

program design, program coding and program testing. All the three stages

contribute to the production of high quality program.

In “TELEPHONE DIRECTORY” we have done system design, source

coding, and program testing and added many more features to facilitate the

user with the best. We have given the user the facility to enter the person’s

record and providing the option to save and delete that record and many

more options.

We can improve the efficiency of the system, thus overcome the

drawbacks of the existing system.

· Less human error

· Strength and strain of manual labour can be reduced

· High security

· Data consistency

· Easy to handle

· Easy data updating

· Easy record keeping

· Backup data can be easily genera

OVERVIEW TO V.B.NET

HISTORY OF V.B.NET:

Visual Basic is a "visual programming" environment for developing Windows (alsoWeb now) applications. Visual Basic makes it possible to develop complicated

applications very quickly. The 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.

Why is Visual Basic popular?

Programmers have undergone a major change in many years of programming variousmachines. For example, what could take days to create an application in other

programming languages like C, C++ could be done in hours with Visual Basic. Visual

Basic provides many interesting sets of tools to aid us in building exciting

applications. Visual Basic provides these tools to make our life far more easier

because all the real hard code is already written for us.

Visual Basic is not only a programming language but also a true graphical

development environment. This environment allows programmers with little

programming experience to quickly develop powerful Windows applications. VisualBasic also has the ability to develop programs that can be used as a front-end

application to a database system, serving as the user interface which collects user

input and displays formatted output in a more appealing and useful form.

Visual Basic is very popular for the ease with which it allows the programmer to

create nice looking graphical programs with less coding unlike many other languages

that take thousands of lines of programmer keyed code. As the programmer works in

the graphical environment much of the program code is automatically generated by

the Visual Basic program.

IMPORTANCE OF V.B.NET:

the name makes me feel that it is something special. In the History of Computing

world no other product sold more copies than Visual Basic did. Such is the

importance of that language which clearly states how widely it is used for developing

applications. Visual Basic is very popular for it's friendly working (graphical)

environment. Visual Basic. NET is an extension of Visual Basic programming

language with many new features in it. The changes from VB to VB .NET are huge,

ranging from the change in syntax of the language to the types of projects we can

create now and the way we design applications. Visual Basic .NET was designed totake advantage of the .NET Framework base classes and runtime environment. It

comes with power packed features that simplify application development.

Briefly on some changes:

The biggest change from VB to VB .NET is, VB .NET is Object-Oriented

now. VB .NET now supports all the key OOP features like Inheritance,

Polymorphism, Abstraction and Encapsulation. We can now create classes and

objects, derive classes from other classes and so on. The major advantage of OOP is

code reusabilityThe Command Button now is Button and the TextBox is TextBox instead of Text

as in VB6

Many new controls have been added to the toolbar to make application development

more efficient

VB .NET now adds Console Applications to it apart from Windows and Web

Applications. Console applications are console oriented applications that run in the

DOS version

All the built-in VB functionality now is encapsulated in a Namespace (collection of

different classes) called System New keywords are added and old one's are either removed or renamed

VB .NET is strongly typed which means that we need to declare all the variables by

default before using them

VB .NET now supports structured exception handling using Try...Catch...Finally

syntax

The syntax for procedures is changed. Get and Let are replaced by Get and Set

Event handling procedures are now passed only two parameters

• Pointer - Used to select and edit objects.

• Picture box - Display device which can contain bit-mapped pictures, text

and line drawings.

• Label - Used to display text that cannot be changed

• Text box - A text input device which accepts keyboard input and supports

editing.

• .Frame - An object which allows other controls to be arranged in logical

groups.

• Command button - Operates like a push button, which is pressed by

clicking the mouse on it.

• Option button - Used in a group of similar controls to select between a

numbers of mutually exclusive options.

• List box - Just like the list part of a combo box.

• Directory list box -Used to display files in a specified directory.

• File list box - Used to select a list of files by their attributes.

• Shape - Used to add objects such as circles, rectangles and rounded boxes

to a form.

• Image - Similar to picture box with less events. Used to display bitmaps.

• Data control - used to access DBs.

• ADO.NET - used to access with external Database

• Connection: Data Source name Which Create Connectivity

TESTING

THE SOURCECODE DECLARED ABOVE FOR THE PROGRAM OF

TELEPHONE DIRECTORY HAS BEEN TESTED AND IT HAS BEEN

FOUND THAT THE ABOVE SOURCE CODE IS OKAY ANDCORRECT.THE PROGRAM INVOLVES MANY TYPE OF

CONVERSIONS. THESE CONVERSIONS HAS TO DONE

CAREFULLY.

MAINLY THERE ARE TWO TYPES OF TESTING:

1-SYSTEM TESTING AND

2-INTEGRATION TESTING

SYSTEM TESTING INVOLVES WHOLE TESTING OF PROGRAM AT

ONCE AND INTEGRATION TESTING INVOLVES THE BREAKING

OF PROGRAM INTO MODULES & THEN TEST.

FUTURE SCOPE

In future one change can be done by adding the fingerprints of the persons

of which the address is entered.And one more major change which can be

done in this project is that to add the snaps of the person of which the

address is entered.We can also add or subtract details of the individual.
