INTRODUCTION

ABSTRACT:

Visual Basic is an interesting topic, which has different types. It has all

The methods have their won features with each having merits and demerits which

Help in data processing. The topic includes their architecture representing the

Elements involved in it and their action is also specified.

Visual Basic 6. allows creating o!"ect#oriented applications. Visual Basic

6. profoundly concentrates on the Internet development features, $ctive % technology,

enhanced controls, enhanced features of e&isting control, client'server, new language

features development, data access, a few design enhancement etc.,

About Visual Basic Lanua!" #

Visual Basic was developed forms the B$1I3 programming language. In 8?FGs

/icrosoft got its start !y developing *=/ !ased interpreted Basic for the early

microprocessor !ased computer. In 8?5ater on,

/icrosoft 3orporation created the enhanced version of B$1I3 called Visual Basic for

indows.

Visual Basic $%&" #

Visual Basic 6. allows creating =!"ect =riented $pplication. hen Visual Basic

originally developed, it allowed to the programmer to create programs using pre#defined

o!"ects, forms and controls. It uses some of the indows ?4 3ontrols. Visual Basic 6.

can !e used to develop !oth standalone systems and 3lient 1erver Based systems.

Visual Basic 6. comes in three categories

1tandard Edition

2rofessional Edition

Enterprise Edition

F!atu'!s o( Visual Basic $%&"#

Visual Basic 6. profoundly concentrates on the Internet development features,

$ctive% technology, enhanced controls, enhanced features of e&isting control,

client'server, new language features development, data access, a few design enhancement

etc.,

Nati)! Co*!: #

$ Visual Basic pro"ect is compiled to native code for faster e&ecution. 2rofiles

native code using new native code compiler option, and de!ug native code using the

Visual 3 environment.

C'!at! Acti)! + Cont'ols: #

(eatures of e&isting controls can !e com!ined, or new control can !e created

form the scratch. $ctive% controls created with Visual Basic have events, data !inding

1upport, licensing support, property pages, Internet features, and more.

Wi,a'*s: #

The application iDard is new and the 1etup iDard has !een enhanced to ena!le

creating a dependency file for a standard pro"ect. In the professional Edition, the $ctive

% control Interface iDard, $ctive % +ocument /igration iDard, +ata (orm iDard,

and property page iDard is new. The 1etup iDard has !een enhanced to supportdistri!ution via the Internet. The installation of remote server components using

+istri!uted 3=/ @+3=/ and *emote $utomation is an added feature. The a!ility to

create dependency files for pro"ects and components created with Visual Basic.

E-t!nsibilit. Mo*!l"#

The new model allows to programmatically e&tending the development

environment and control pro"ects, events, code, and Visual elements.

Multi1l! 2'o3!ct: #

/ultiple pro"ects can !e opened in the same instance of Visual Basic, with is

useful for de!ugging $ctive % controls.

C'!at! Acti)! + Docu4!nt: #

$ctive% document s can !e created that !oosts the Visual Basic application to the

Internet Browser indows. The data control, +$= or /icrosoft $ccess, you can create

that is virtually data!ase independent, !ecause "et automatically performs all synta& and

data manipulation translations.

This feature allows us to access =+B3 data sources throughout the *+= with

+$= o!"ects, !y passing the /icrosoft et +ata!ase Engine. e can also use =+B3

2ro"ect, properties, +e!ugging, and =!"ect Browser windows can !e doced in

the development environment and'or lined to each other. Tool!ars can !e doced,

undoced, or lined to each other.

Auto4ation: #

$ technology that ena!les application to provide o!"ects in a consistent way to

other application, development tools and macro languages. (ormerly nown as =>E

$utomation.

Class: #

3lass is the formal definition of an o!"ect. The class acts as template which an

instance of an o!"ect is created at run time. The class defines the properties of the o!"ectand the methods used to control the o!"ectGs !ehavior. 3lassGs uses can typically !e

categoriDed as one of three general types. They are

3reation of Business =!"ects

E&: Employee o!"ect

Encapsulation of programming functions

E&: Encapsulate the code that opens a record set in a class module

Visual Basic $dd#Ins E&: 2rogram iDard

2ol.4o'10is4"#


8/65

2olymorphism relates to the use of the same method name in various o!"ectsJ for

e&ample, a print method for the printer, a form, or a picture !o&. hile the name of the

method is the same, the actual code for the method in each o!"ect can !e different.

However, !ecause the code for the method is encapsulated in the o!"ect, each o!"ect

nows how to perform the correct tas when the method is called, this feature allows

classes to support multiple interfaces. sers of components can early !ind to these

interfaces, regardless of the o!"ect that implements them.

Enca1sulation: #

The data a!out an o!"ect and the code used to manipulate the data are contained

within the o!"ect itself. The data is stored as the properties of the o!"ect and the code as

the methods of the o!"ect. This feature allows the o!"ect data and code to stand alone,

independent of outside routines.

T0! Co41on!nt Ob3!ct Mo*!l 7COM8"#

The 3omponent =!"ect /odel @3=/ is a specification. It specifies how to !uild

components that can !e dynamically interchanged. 3om provides the standard thatcomponent and clients follow to ensure that can operate together.

3=/ is /icrosoftGs top#level, all encompassing !inary and wire specification for

the interoperation of one app with another, across multiple applications, machines, and

hardware types. It provides the following features.

1ingle programming model

Binary compati!ility

Bina'. Co41atibilit. an* C'oss#1lat(o'4 D!)!lo14!nt: #

The first ma"or advantage of component technology !inary compati!ility and

cross#platforms. 1ince !ecoming an Industry#wide standard, 3=/#compliant client

applications and servers are independent of the development language and operating

system.

Co*! R!usabilit.: #

The second ma"or advantage of component technology is an enhancement of +>>

technology. 3=/ components e&pose groups of methods, nown as interfaces, through

which clients interact with o!"ects. Because these interfaces are documented, many

clients for a variety of different purposes can reuse the code that creates those o!"ects.


10/65

V!'sion Cont'ol: #

The last ma"or advantage resolves issues related to version control. 3=/

components are said to !e self#versioning. This means that new functionality can !e

added to a component without affecting clients that already use the components.

(unctionality is not lost when components are upgraded it is always enhanced or added.


11/65

MS#ACCESS:

hen we create a /icrosoft $ccess data!ase, we create one file that contains

the data and ta!le structures as well as the )ueries, forms, reports and other o!"ects that

mae up the data!ase.

2rotecting information can !e an important part of developing a /icrosoft

$ccess data!ase. By securing your data!ase, you can control what a user, is a group of

users, can do with data!ase o!"ects. /icrosoft $ccess security made up of several pieces

that must !e in place !efore security is complete. 1ecurity relies on a relationship

!etween /icrosoft $ccess stores account information with the wor group and

permissions assignment in the data!ase @.md! file /icrosoft $ccess Version F system

data!ase includes several internal security enhancements.

Encrypting a data!ase maes it indeciphera!le !y a utility program or word

processor. Encrypting a data!ase compacts the data!ase file and maes it indeciphera!le

!y a utility program or word processor. +ecrypting a data!ase reverses it indeciphera!le

in order to protect it from unauthoriDed viewing or use.

The proposed system is for maing easier to manage su!scri!er details, post

details, money order details, !ills. 1o this will !e developed for helping the post office

administrative the a!ove things. The overall system is control through the main menu.

The main money contains 6 parts.

E+ISTING SYSTEM:

The present system of 2ostal service does not contain the courier transactions and

maintain the details of all other transactions such as maintaining money order details

speed post transactions register post transaction saving and recurring !an transactions all

these are carried out manually. This postal system is made into atomiDation in order to

render services more )uicly and efficiently to the people.

CONCLUSION

$ computeriDed postal department system has !een developed and the systemwas tested with sample data.

The system results in regular timely preparations of re)uired outputs. In

comparison with manual system the !enefits under a computer system are considera!le in

the saving of man power woring hours and Eiffel.

2rovision for addition and deletion of customers is there in the system it is

possi!le to view that proper filling system has !een adopted to slate date for future. The

entire pro"ect runs on windows environments.

The system can !e used to mae !etter management descri!ed at appropriate

time. The user gets amount and timely information system.


64/65

13=2E =( E0H$03E/E0T

The system may !e further updated or modified at will owing to its simple

structure. If the organiDation willing the add a new module that would allow the vendor tothe post office system. /ore over the developed system does not provide any ind of

facility for maing of the information.
