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
Book Shop Management System.
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
Book Shop Management System.
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
Book Shop Management System.
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
Book Shop Management System.
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
Book Shop Management System.
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
Book Shop Management System.
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.
Book Shop Management System.
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:
Book Shop Management System.
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.
Book Shop Management System.
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:
Book Shop Management System.
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.
