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.
