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

Book Shop Management System.

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

Book Shop Management System.

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”

Book Shop Management System.

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

Book Shop Management System.

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: 

Manual system involves a lot of paper work, so it becomes time consuming and costly.

Book Shop Management System.



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

Book Shop Management System.



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.
