INTRODUCTION

PC EXPERT is a set of small computer utility applications..It is a tweaking utility basically designed for windows xp. PC EXPERT allows you to change a multitude of settings in the registry. It consists of some network tools also which can be useful for students and administrators which will allow them to find different information such as hosting provider of a particular website, who is lookup, trace route etc. Regardless of all views the customization tool has a lot to do with a basic administrator or with normal regular user who has a lot expectation from O.S. where the user is limited from the customization point of view wherein user needs a lot but gets nothing Base of this PC Expert is two types of tools viz. Net tools and PC Tweaking Tools. Net tools are basic tools for administrator in this aspiring student who wants to gain more knowledge regarding it. Next category of tools is PC Tweaking7

Tools which will help basic user and to all who has great imagination from pc customization point of view PC Expert will basically help all user as well as the professionals to get more advanced information about hidden windows utility.

PROJECT SELECTION

13

PROJECT SELECTION

Computer software like customization toolkits have become a driving force in todays modern technology world. It is a software which helps the administrator to handle the entire network or a single computer according to its needs. It serves as a basic reference to the administrator for PC customizing. In such growing IT revolution it is very difficult to choose a complete customization tool kit with various utilities. The various projects that can be implemented are:

SYSTEM SOFTWARE:

14

These are the programs written to service other programs. E.g. compiler editors etc. System software implements control function that enable application software to interface with system elements. It is very challenging to build system software but ,big organizations have already developed them and having a monopoly in t6he market(e.g. Norton, Microsoft and Turbo). It is very difficult to find sponsors for system software.

REAL TIME SOFTWARES:

Programs that monitors/analyses/controls the real world events, as they occur, are called real time software s. Real time software are very difficult to develop because of limited knowledge, time constraints, and high investments.

EMBEDDED SOFTWARE:

15

Developing an embedded system needs perfect in-out embedded working of product at hardware level which companies do not release. It is difficult to go ahead with buildings an embedded system.

PERSONAL COMPUTER SOFTWARES:

Today thousands of softwares like word processors , spread sheets, entertainments etc are available free or at a very low cost thus such projects has almost no market value.

BUSINESS SOFTWARES:

Management Information systems (MIS) accsses one or more databases containing business information for smooth operation of organization and for decision making.

APPLICATION SOFTWARES:

Application software implements the procedure that is required to accommodate information processing functions. My project is a application software .It essentially provides emailing services to organizations.

16

We have selected this project due to the following reasons:

1.

As I have studied visual basic in the 6th semester in our subject System Analysis & Designing especially in practical, so it becomes easy to create a logical model of the overall system on the basis of my knowledge.

2.

In addition it also helps to make the project management easier as I have studied in the subject System Analysis & Designing

3.

This idea was also aroused to us through some reference computer magazines like chip, digit and many more

4.

We also chose this project as this one is different from all others ever yet done

PROBLEM STATEMENT

19

PROBLEM STATEMENTDevelop an application that allows user to do following task:

All tools are divided in two sections 1. NET TOOLS: - In this section some network related applications will be added. Such as port scanner, route tracer, WHO IS lookup and many more PC TWEAKING TOOLS :- Applications in this section will allow the user to customize their pc in the way they want and should allow the administrators to secure their pc from intruders

2.

1) NET TOOLS20

1.

Host Lookup :-

Create an application which will allow the user to find IP address of any domain or host.

2.

Fetch Html Source Code:-

This application should allow the user to see the html source code of any webpage directly. This will decrease the steps for viewing the source code of webpage.

3.

Port Scanner:This application should allow the user to scan any IP address for open ports. It will use TCP connect scan method for port scanning TCP Connect scan: - This type of scan is the most reliable, although it is also the most detectable. It is easily logged and detected because a full connection is established. Open ports reply with a SYN/ACK, whereas closed ports respond with an RST/ACK.

4.

Port Listener:This will allow the user to listen on any particular port in their pc and see what is happening at that port.

5.

Trace Route:This should allow the user to see how the connection is established between two systems. This will show the route of the data transmission between two systems21

6.

Ping Ip address:This application will allow the user to ping any IP address. It will also allow the user to determine the number of packets for ping with good user interface

7.

Who is Lookup Utility:This application should allow the user to find the host provider for any domain name and other related info of the domain name.

2) PC TWEAKING TOOLS8. Change Title of Internet Explorer Window:-

Create an application which will allow the user to change the title of the Microsoft Internet Explorer.

9.

Change The Display Name Of a processor:-

Create an application which allows the user to change the processor name of the pc. This will allow the user to customize his pc 10. Desktop Lock:22

Develop an application which can lock the desktop and disable task manager. It should deny the access to desktop without proper password. When the desktop is locked , no one should be able to access the documents, browse computer or use programs 1. Change Windows Default Icons:-

Create an application which will allow the user to change default windows icons like My Computer, Recycle Bin icons etc. 2. Logon Banner:-

Write a code and develop an application to allow the user to create a logon banner. This application can be used in a company to display the companies private policy before someone logs in. 13. Change Windows Media Player Title Bar:Write a code and create an application to allow the user to change the windows media player title so that user can customize his pc in the way he wants

1.

Speed Up Start Menu Display Speed:-

Microsoft has added some delay in start menu display. Create an application which will allow the user to set the delay time

2.

Screen Shot Capturing Tool:-

Create an application which allows the user to take screenshots easily and which will take screenshots automatically23

3.

Add Item to right click:-

Develop an application for normal pc users which allows them to add items to right click (In Right click Menu for Folder and File)

4.

Add any program to startup:-

Many software adds themselves in the startup automatically but it is not easy for normal users to add items to startup, so develop an application which allows the user to add items to startup easily.

Add some more utilities in this set if possible

24

PROJECT MANAGEMENT

25

PROJECT MANAGEMENT:Project management is a process of scoping, planning, organizing and controlling the development of an acceptable system within a specified time-frame.

For the proper management of a project I required eight different phases to develop our application .They are as follows:

1.

INITIAL INVESTIGATION1. Negotiate preliminary scope. 2. List problems, opportunities and directives

3.

SYSTEM DESIGN

30

SOFTWARE SELECTION31

SOFTWARE USEDOur application is developed using: 1. 2. Microsoft Visual Basic 6.0 API.

API:32

Windows is a graphical user interface. It uses graphics to organize our workspace. In windows environment, we choose items and execute programs by pointing and clicking with mouse. Moreover, the programs (such as MS-Excel, MS-Word) can run only within Windows, because Windows provides build-in functions and data that is not available in other environments This system defined functions that an application can call are provided by an interface known as the application program interface or API. The API is an interface between an application and the windows environment. The API is provided by the operating system (Windows) to all applications.

33

Visual Basic:The predecessor of Visual Basic was BASIC (Beginners All Purpose Symbolic Instruction Code). BASIC was mainly interpreter-based whereas Visual Basic is partly interpreter-based and partly complier-based. The main advantage of Visual Basic is that it is a Rapid Application Development tool. This is the main reason why visual basic is extensively used as a prototyping language. Microsoft Windows manages to handle multiple windows, events, messages. Dealing with all of possible combination of windows, events and messages could be mind-boggling. But Visual Basic insulates you from having to deal with lowlevel message handling. Many of the messages are handled automatically by Visual basic; others are exposed as event procedures for your convenience. VB is extensively used as a prototyping language as it is a Rapid Application Development Tool. It insulates you from having deal with low-level message handling.

DATA FLOW DIAGRAM

DATA FLOW DIAGRAM

36

It is a graphic representation of a system that shows data flows to, from and within the systems, processing a function that changes the data in some manner and storage of the data. A DFD is the starting point of the design phase that functionally decomposes the requirement specifications down to the lowest level of detail.

The symbols used while creating a DFD are:
