Preface Computer is fast emerging as a daily need in walks of life. The

knowledge of computers and programming language has become basic

skill need to service in today’s information based society. Every business

institution and the corporate section, make a use of computer for making

their operation efficient & effective.

Book distributors transaction handling is one of the complex process

and it required computerized system to maintain overall transactions in a

easier manner. Due to heavy demand of books in these competitive

worlds, data increase so much. Books shop required up to date

information about the customer who purchased books or about the

suppliers from where books are purchased. The books shop requires large

amount of data to record and to store, which are collected from the Book

House.


About Visual Basic 6.0

Visual Basic 6.0 is Microsoft latest and greatest version of the

Visual Basic programming language. Although writing programs can be a

tedious chore at times Visual Basic educes the efforts required on your

part and marks programming enjoyable About Visual Basic 6.0 Visual

Basic marks many aspects of programming as simple as dragging graphic

object onto the screen with your mouse.

Even driven programming Traditionally programming is essentially linear and is based on the

flow of The execution. Operation runs for fixed span or until they reached

a decision Point. At the decision point the programming branches

depending on the point to the program or the status of various variable of

the program. This operation continues till the program is completed. Once

the program execution starts it is impossible to interrupt the activity. The

programmer is responsible for the structure looks and the flow of program.

If the programmer wants a good user interface, be has to explicitly write

the long and complex code for the user interface of the program.

In the conventional method the programs are usually written

in a top Down manner. This may be done either using the structure

programming Approach i.e. by breaking up the program in to small

sections of independent Procedures or function or using a modular

approach i.e. by creating a program From a set of more or less self

contained function and procedures. Theoretically, This makes a possible

to reuse the modules to be used in other programs. In Practice, there are

generally a very few routines that can be reused without major

Reworking. On this data is declared globally, any function or procedure


can Access the data, which might put it at the mercy pf any function or

procedure. The likelihood of incorrect data manipulation is high. If data is

declared locally only the procedure in which the data is safer, it is very

restricted.

In object oriented programming, a method (the function or

procedure of an object) Know what data if can manipulate them. There is

no confusion about who control whom. Declaring object and enclosing

method and their data in a Class achieve this. General procedures the

kind use in structured programming cannot access data with an object

without using the object methods which are Designed too manipulate

their data.

In procedural program, the order of procedure and control

statement determines the program, flow of control. This implies that the

programmer knows the entire flow of the program while he developed it.

In program designed to capture the essence of the dynamic world, this

assumption is unrealistic and cumbersome.

Object oriented programming captures these logical relationship

in object Determines the flow of control in objects clarify the

communication along the Component of an application. Object

responds to the other objects. Massages move through the system, not

data. Instead of invoking a Function on some data like in conventional

programming method, a message is sent to object. This is the principle of

operation in windows, Visual Basic is Object oriented, i.e. revolves around

ready made objects, and it is event driven, All the activity in program are

triggered by one event or another. Each object also Has it’s own event

handling procedures. The Visual Basic system knows all about this already.

It knows what button is and how it work. It also knows how to

handle Menus dialogue boxes, drive and directory list and much else. The

programmer’s job is to determine where, how and when an object


appears on the screen what it is to do. What is caption reads what colors

it would He end what happens, when an event occurs. The events are

trapped by the Execute, when the event occurs.

Because the program code run through event and as such at

any point a Whole range of event might be possible, the program flow is

not as fixed as in a Conventional program. Operations do not have to

follow a set if sequence, and Can be easily interrupted, suspended or

abandoned. The processes of program Design reflex the nature of the

system. One begins by creating the screen layout, And work out words

from here , adding first the code that will run in response to Specific

events and then any necessary code to co-ordinate the whole program.

This approach of programming is called event driven programming.

Programming terminology The terminology that is used in Visual Basic programming are:

Forms

Controls

Module

Project

Procedures

Properties

Methods

Events

Forms

The form is the basic object used in Visual Basic application

development. It is a window, initially black on which controls are placed

to create the screen display. The forms size, colors type are

programmable. Code can be attached to the form, which would be

executed when the form is loaded, closed or when the mouse is clicked


or moved on the form. A simple application may use only one form but a

complex application may use many form activated by various controls

pasted on the form. Each of the form on the application is saved in the

disk as separate file with an extension “Form”

.

Controls

These are objects which can be pasted on to a form and these

Controls range from simple labels, which are used to display text on the

screen on Form, or picture boxes for buttons, check boxes, list and other

menus, To file management utilities and spreadsheet style grids. Their

properties, And event they can handle, very to suit their nature. Each

control can have coed Attached to it, though not all will have. A text

label or graphic image, for ex. May be There simply to improve the

display, and not as the start point for any activities.

Module Code that is attached to form is accessible form anywhere on that

Form, but a program more than one form. In such a case a code

attached to a form. In such case a code attached to a form is not

available to the other forms. In this case, the code that is required to be

made available to the other forms is written in a separate module.

Modules are code segments, which are not written inside the

scope of any form. They have global scope. These cannot be made

visible during run time. It is like any other program code. There may be

several modules in one program and each is saved as separate file. These

files have an extension of “BAS”, because these are BASICcode modules.

Procedure


All the code in the visual basic program is written in the forms

of procedure, or subroutines. Most of these procedures will be attached to

the event some controls or forms. Some of the procedures would be

separately written inside the modules as global functions. All the

procedures start with keyword Sub and close with the keyword End Sub.

Project The project is a file in which all the form files(*.frm files) and the

modules(*.bas files) that make up the entire application, is kept . These

have an extension of “* .Mac”. they are called make file thus any

application wil have a “* . vbp”file.

Properties Each control has a set of predefined properties, method and events

that it will respond to. Properties are simply characteristics of an object or

control. They are used to store data describes some particular attribute of

the object such as color, size or the picture present in a control. The one

property that every object must have is the Name property. This is use to

refer to the object must be unique in a project. Visual Basic assign default

name to control when you add them to your form, but you can alter

these at design time(and you should alter them at design time)to make

your code more descriptive. Note that you can’t change a control’s

Name property at run time, and these won’t appear in the properties

window .

Properties can be set at design time using the properties window or they

can be set and reference within your Visual Basic code. Properties are

reference in the form of object name. property and in some respect you

can think of them like a variable. You can assign a value to a property


just as you assign a value to a variable. here we assign the text string

“john smith” to text property of the object called Text1:

Text1.text=” john smith”

Just as with variable, properties can also be used as part of other

statement:

Print your name is: Text1.text

Methods Methods are action that can be performing on an object.

These are like procedures. They are written in code in the form object

name. method parameters for e. forms have a move method that moves

them to the procedure specified by the parameter. In this case, the top

left of the form would be move screen coordinates (370,915) as

Form1.move 30,915

When you referred to the property or method of an object

that resides in a form other than one form which you are refereeing it , you

will need to give it a fully qualified reference. These means preceding

name of the object with the name of the form like this:

FormName.ObjectName.property

This sort of reference to an object can be extended in the case

of OLE application to include the name of the project before the name of

the form. If you don’t supply a fully qualified reference, Visual Basic

assumes that you are referring to the project and form in which you are

making the reference.

Events Events are the key to Visual Basic programming each object in the

Visual Basic can be respond to a predefined set of events. These would

be movement of the mouse, the pressing of the key on the keyboard or


the lapsing the particular period of time. You can see which events a

control can respond to by adding controls to your form and double

clicking it to bring up the code window. The procedure dropdown list box

in the top right corner of the code window contains a list of all the events

that a control can respond to. If you select one of the item in the list box,

the first and last lines of a procedure are added to your code. This

proce4dure will be triggered whenever that particular event occurs, so

any code that you add to the procedure will be executed at the same

time. This is how you create Visual Basic code to respond to user

interaction and other events.


Current system

The book shop contains different types of books of various

subjects with various quality according to the customers needs and

requirement. The main thing of the book shop is to maintain lot of records

for the daily transaction of the business. It is necessary for every business to

maintain all records, which show the profit and loss of the business.

In today’s life people have very little time and many things

to do. They have to manage all this unbalance workload, although every

one wants to achieve all their ambitions and dreams. And the present

system of managing Books is very time consuming so it is very difficult to

maintain good records and fast service. The paper work is becoming very

difficult to handle day by day.

Currently we have to keep track of each and every thing about the

book shop on the paper or in register. We have to maintain lot of registers

to enter these large volumes of data. This leads to the wastage of

stationary.

Some disadvantages are:


Manual system involves a lot of paper work, so it becomes time

consuming and costly.

The chances of errors in calculation of delivery of Books are more in

the current manual system. The calculation of total collection for day

or month or year is very difficult.

Currently no security is provided to the large amount of data of the

every book details.

It becomes very difficult to maintain details of every Book as records

increases day by day.


Proposed system

While creating new software we should analyze what is the

basic need of the software. Analysis is nothing but a planning of creation

of software to get proper output from it. Analysis is details study of projects

that you want to show in your software solving problems.

The basic need of the software is to save the time of the user

with the help of all useful information. And also to maintain the collection

of data in your computer systematically, so that its easy to understand.

The proposed system provides lot of facility to the user to store

information of the Books and it provides information in quick time in a

systematic manner. The processing time on the data is very fast. It

provides required data quickly to the user and also in specified manner to

the user. All the information of Books changes is given to the user and also

the reports are also generated according to the requirement of the user.

Today it is becoming very difficult to maintain record manually. This

software system easily does the job of maintaining daily records as well as

the transaction according to the user requirements.

Some advantages are:


User – friendly software

Easy to record all data about the Books and its details.

It saves time of the user as well as prevent paper work

It provides the security to the database that is large amount of

important data of the hospital.

It provides more reliability for keeping information.
