INTRODUCTION TO VISUAL BASIC

VISUAL BASIC is the Graphical User Interface (GUI) language. It is the

language that many developers including Microsoft themselves are using to write new

applications software, Microsoft Corporation created it in 1991. It is a high level

language. With the help of Visual Basic we can communicate with other applications

running under windows. It is an internet based and an object oriented programming.

( 4 )

Technology Detail’sTechnology Detail’s

Visual Basic is substantially different from traditional Basic, though there are

similarities. Visual Basic requires a different approach to developing programs and to

learning the language. But in Basics, we can develop a program line by line, testing

each command as we write it. With Visual Basic we must develop our programs and we

can understand across a broader front.

In Visual Basic we can write a program by assembling the object that we will

use for screen displays and interaction with the users, adjusting the properties of those

objects, determining which events we will respond to, thinking through the variables

we need for holding data and for passing information from one part of the program to

another, and writing the command lines that will run when events are activated. At

each stage of development we may add to or change any aspect of the program, but it

must be done with an awareness of how it will affect the other aspects. Objects,

properties events and code are all intimation. Visual Basic lets us add menus, text

boxes, command buttons, option buttons, check boxes, list boxes, scroll bars, file and

directory boxes to blank windows, we can use grids to handle toolbar data,

communicate with other window applications and access database. We can have

multiple windows on a screen. These windows have full access to the clipboard and to

the information in most other window application running at the same line.

So Visual Basic is a collection of files. It is a very easy language and flexible to

use. This language also contains all the features of basic language. It is an event

driven programming. It is also called a friend of a user. One of the advantages of

visual basic is that it is a grammar free language. It provides both compiler and

interpreter.

Programming in Visual Basic

Programming in Visual Basic was written around Visual Basic 3.0, standard

edition but virtually all of the techniques and concepts apply equally well to Visual

Basic 2.0.It doesn’t have advanced feature or development of free standing commercial

applications, for which the professional edition is necessary. There was another

version of Visual Basic that is Visual Basic for DOS. This version was out of use.

( 5 )

Windows is the natural medium for Visual Basic. Then come more advanced version

like Visual Basic 4.0, Visual Basic 5.0, and Visual Basic 6.0 at present the latest the

Visual Basic 6.0.

EVENT DRIVEN PROGRAMMINGVisual Basic is Object Oriented, i.e. it revolves around ready made objects and

it is called as EVENT DRIVEN, i.e. all the activities in a program are triggered by one

event or another. Each object has its own properties, determining its position, size,

color, the appearance and nature of its text, and much more. Each object also has its

own event handling procedures.

In an event driven application the code doesn’t follows a predefined path, it

executes different code section in response to events. Events can be triggered by the

user action, by message from the system of other application or even from application

itself. The sequence of this event determines the sequence in which codes executes.

Thus the path through the application code written each time the program runs.

Visual basic system knows all about event handling procedures. It knows what a

button is and how it works. It also knows how to handle images, menus, dialog boxes,

driven and directory lists, and much else. The programmer’s job is to determine where,

how and when an object appears on screen, what its caption reads and what happens

when an event occurs. The event might be the opening of a form, the user clicking on a

box. The programmer does not have to write code to trap these events the system does

that automatically. Because the program code runs in response to event, as at any point

whole range of event might be possible. The flow of execution is not as fixed as in a

traditional program.

About Visual Basic -

Visual Basic is the most Popular Object Oriented event Driven Programming language. It revolves around readymade objects, and it is event driven i.e. all the activities in a program are triggered by one event or another .The main advantage of visual Programming languages is that we can concentrate on what we want our program to do, not how to get the programming language to do it. Some Visual Basic features are: -

1/ Compatibility: Visual Basic is capable of producing software as sophisticated as any other data access techniques available.

( 6 )

2/ Flexibility: It not only provides database access but can also be used to link it with other word processor, spreadsheets software etc.

3/ Familiarity: Because it can be said as an extended version of Basic, which is very easy to learn and work with, its syntax seems to be more familiar.

4/ Features: Various Additional Features like ADO reports and other various types of Active X controls are supported by this application, which helps widely in development of the Project.

MICROSOFT ACCESS

The goal of the access is to help you get your work done in the least of time, with a minimum of effort.

What type of application can you develop in Access?

Microsoft Access offers a variety of features for different databases needs. It can be used to develop five general type of application:

1. Personal application.2. Application used to run a small business.3. Department application. 4. Corporation- wide application.5. Front- end for enterprise-wide client/server application.

What is Database actually?

The term database means different things to different people. For many years in the world of Dbase was used to describe a collection of fields and records in a client/server environment. Dbase refers to all the data schema, indexes, rules, triggers and stored procedures associated with a system in access terms, a dbase is a collection of all the tables, queries, forms, reports, macros and modules that compose a complete system. Actually database is a collection of related information. Here information is stored in tabular form one record a show all possible attributes of an entity. In a simple word entity can be identified by its attributes like his name, color, height and hairstyle etc identify a person. So in databases a record makes topple while attributes make fields.

About Ms Access -

This is a Backend Tool widely used for Personal Computer as a Data Base. The

relational database is a well-defined theoretical model of working with and managing

a set of data that attends to three specific things:

( 7 )

Data Structure, Data integrity and Data manipulation .The MS Access has a

distinct component, which adheres to these requirements. The basic Data Structure in

Access is Table having fixed number of columns but variable rows.

The Data integrity rules of the relational models can be defined within Access

relationship using integrity constraints. When a table is created in Access the integrity

rule is defied at that very time.

MS Access has many important features that make it not only an exceptional

database Management System but also an excellent database for personal system in

windows environment,

- It provides highly secure environment to do better handling of database.

- It can handle reasonable amount of data.

- Easily support all window based systems

SYSTEM ANALYSIS

System Analysis

A system is a set or arrangement of functionally dependent component or

working together to attain a predefined goal by processing information. It is the

process of examine of a business situation with the intent of improving it through better

procedure and method. It is the process of gathering and method. It is process

gathering and interpreting facts.

Timing problems and using the information to recommend improvement to the

system. Analysis is used gained and understanding of the conclusion of the system there

is a system description and as set of requirement for a new system. It there is on

existing system, then the analysis only defines the requirement. The step, which follows,

will propose a new system that meets these requirements.

The new system may be built a fresh or by changing the existing system.

Development being by defining a model of new system an continuous by converting

these model to a system in a short analysis specifies what the system should do.

Analysis objective

An efficient system analysis always plays the role of strong foundation for

development of any proposed system. Information play key role, as the horizon of

knowledge keep on expending, since this project is anaphor to convert the manual in to

computer based system, a through knowledge of the day-to-day functions of present

system of mandatory the objective of this study comprise.
