1. INTRODUCTION:

This project, GAS AGENCY, include supplying of gas to various customers, to maintain the reorderlevel of the gas cylinders, and to standardize theprice of the gas cylinders.

To get a cylinder the customer must beregistered with the gas agency. The details of thevarious customers are maintained. The cylindertype could be commercial or domestic. Thetransactions carried out by the agency are also

recorded. The stock that is available with the gasagency is also recorded, if any defects found incommercial or domestic are also recorded andreturned.

A master price list also maintained. This showsthe different price for the commercial and domesticcylinders.

There are various reports have been generatedsuch as customer report, daily report, weeklyreport, date wise report and stock report.

This project has automated the operations of agas agency completely.

LANGUAGE DESCRIPTION

a). About Visual Basic Language

Visual Basic was developed from the BASICprogramminglanguage. In 1970s Microsoft got its start bydeveloping ROM based interpreted Basic for theearly microprocessor based computer. In1982,Microsoft QuickBasic revolutionized Basicand legitimized as a serious developmentlanguage for MS-DOS environment. Later on,Microsoft Corporation created the enhanced

version of BASIC called Visual Basic for Windows.Visual Basic 6.0 :

Visual Basic 6.0 allows creating ObjectOriented Application. When Visual Basic originallydeveloped, it allowed to the programmer to createprograms using pre-defined objects, forms andcontrols. It uses some of the Windows 95 Controls.Visual Basic 6.0 can be used to develop bothstandalone systems and Client Server Basedsystems.

Visual Basic 6.0 comes in three categories

Standard Edition

Professional Edition Enterprise Edition

Features of Visual Basic 6.0:-

Visual Basic 6.0 profoundly concentrates onthe Internet development features, ActiveXtechnology, enhanced controls, and enhancedfeatures of existing control, client/server, and newlanguage features development.

Native Code:-

A Visual Basic project is compiled to nativecode for faster execution. Profiles native codeusing new native code compiler option, and debugnative code using the Visual C++ environment.

Wizards:-

The application Wizard is new and the Setup

Wizard has been enhanced to enable creating adependency file for a standard project. In theprofessional Edition, the Active X control InterfaceWizard, Active X Document Migration Wizard, DataForm Wizard, and property page Wizard are new.The Setup Wizard has been enhanced to supportdistribution via the Internet. The installation of

6

remote server components using Distributed COM(DCOM) and Remote Automation is an addedfeature. The ability to create dependency files forprojects and components created with Visual Basic.

Extensibility Model:-

The new model allows to programmaticallyextending the development environment andcontrol projects, events, code, and Visual elements.

Declare, Raise, and Handle Events:-

Objects provided by the components can raiseevents that can be handled in other applications, orby our objects, using with Events variables, Eventsprovide a simple alternative to asynchronouscallbacks.

Create Active X document:

ActiveX document s can be created that booststhe Visual Basic application to the Internet BrowserWindows. The data control, DAO or MicrosoftAccess, you can create that is virtually databaseindependent, because jet automatically performsall syntax and data manipulation translations.

b). MS-Access:

When we create a Microsoft Access database,we create one file that contains the data and tablestructures as well as the queries, forms, reportsand other objects that make up the database.

Protecting information can be an importantpart of developing a Microsoft Access database. Bysecuring your database, you can control what auser, is a group of users, can do with databaseobjects. Microsoft Access security made up of several pieces that must be in place before securityis account information with the work group and

9/66

permissions assignment in the database (.mdb) fileMicrosoft Access Version 7 system databaseincludes several internal security enhancements.

Encrypting a database makes it indecipherableby a utility program or word processor. Encryptinga database compacts the database file and makes itindecipherable by a utility program or wordprocessor. Decrypting a database reverses itindecipherable in order to protect it fromunauthorized viewing or use.

3. SYSTEM ANALYSIS:

a). System Definition

This operations of a gas agency has to beautomated completely.

9


10/66

This project, GAS AGENCY, include supplying of gas to various customers, to maintain the reorderlevel of the gas cylinders, and to standardize theprice of the gas cylinders.

To get a cylinder the customer must beregistered with the gas agency. The details of thevarious customers are maintained. The cylindertype could be commercial or domestic. Thetransactions carried out by the agency are alsorecorded. The stock that is available with the gasagency is also recorded, if any defects found in

commercial or domestic are also recorded andreturned.

A master price list also maintained. This showsthe different price for the commercial and domesticcylinders.

There are various reports have been generatedsuch as customer report, daily report, weeklyreport, date wise report and stock report.

b). Existing System:

The operations in the gas agency were done bymanually. There were lots of problems to maintainthe operations manually. When they wantedproduce the reports like billing, daily transactions itwas very difficult to tackle the situations. Thenthey decided to automate their operation.

10


11/66

c). Proposed System.

The system automates the operations of a gasagency. The system was designed in such a waythat it is useful to any gas agency rather than for aparticular agency.

This system would maintain the customer and stock details. Acustomer must be registered with the gas agency in order to get the gascylinder. All the details of the customer are maintained in the database.

The cylinder type could be commercial or domestic. The transactionscarried out by the agency are also recorded. The stock that is availablewith the gas agency is also recorded, if any defects found in commercialor domestic are also recorded and returned.

There are various reports generated such ascustomer report, daily report, weekly report, datewise report and stock report.

a).About the project:

To enter into the project, give the correctpassword else it gives the INVALID PASSWORD.

The main form contains the following menus,MainTransactionReportsExit

Main menu:

The main menu having the following items,

Customer entry.Stock entry.

Customer entry form allows to add, delete,modify the customer details. In this form one canview the customers, who are registered with theagency.

Stock entry form allows to enter the stock details, that is the stock received and automaticallyupdated in the database. The form shows thecurrent stock. If the current stock comes at thereorder level, it cannot deliver the goods. Thedefects items also maintained in the database andalso returned.

6. SYSTEM TESTING:

In a software development project, errors canbe injected at any stage during the development.Testing performs a very critical role for quality andfor ensuring the reliability of software. Duringtesting ,the program to be tested is executed withset of test cases ,and the output of the program forthe test cases is evaluated to determine if theprogram is performing as it is expected to. Due toits approach, dynamic testing can only ascertainthe presence of error in the program; the exact

nature of the error is not usually decided by testing. Testing forms the first step in determining theerrors in the program. Clearly the success of testing in revealing errors in programs dependscritically on the test cases.

Testing is usually relied upon to detect thefaults that occur during any phase of the softwaredevelopment cycle ,in addition to the faults thatintroduced during the coding phase itself. Forthis ,different levels of testing are used whichperform different tasks and aim to test differentaspects of the system. the basic levels of testingare unit testing ,integration testing ,system andacceptance testing. the different levels of testingattempt to detect different types of faults.

Test Plan:

A Test plan is a general document for the entireproject, which defines the scope approach to be

taken, and the schedule of testing ,as well asidentifying the test items for the entire testingprocess and the personnel responsible for thedifferent activities of testing commences and canbe done in parallel with the coding and designphases, the inputs for the test plan are,

Project plan

Requirements Document

System Design Document

The project plan is needed to make sure that thetest is consistent with overall plan for the projectand the testing schedule matches that of theproject plan. The requirements document and thedesign document are the basic document used forselecting the test unit and deciding the approachesto be employed during testing.

White Box Testing:

A white box testing technique id described asfollows:

Control Structure Testing:

Conditional testing is a test case designmethod that exercises the logical condition in aprogram module. The possible types of componentsin a condition include a Boolean operator, Booleanvariable, pair of Boolean parenthesis relational

operator or an arithmetic operator.

Data Flow Testing:

Data flow testing method selects test path of program according to the location of definition anduses of variables in the program .they are usefulfor selecting test. They are useful for selecting testpaths of a program containing nested if and loopstatements.

Loop Testing:

Loops are the cornerstone for the vast majorityof all algorithm implemented in software looptesting is a white box technique that focusesexclusively on validity of loop construct.

Black box Testing:

Black box testing method focuses on thefunctional requirements of the software. black box
