INTRODUCTION

Desktop Spy is used to lock remote desktop so that it prevents unauthorized users

accessing the information. Once system acts as a client and other system acts as server.

This is similar to data transfer. From server the commands are sent to lock client system.

Once the command is received locking operation is performed on client desktop. Client

window is deactivated. No action can be performed this side. Server need to send

command to unlock the remote system. Once the data is received client desktop is

released and task is performed. And application is used to remote desktop shutdown and

opens the internet explorer. This project is deals managing in controlling network client

system.

1.1ABSTRACT

Multicast Server, included with Windows XP Professional, enables you to connect to

your computer across the Internet from virtually any computer. Once connected,

Multicast Server gives you mouse and keyboard control over your computer while

showing you everything that's happening on the screen. With Multicast Server, you can

leave your computer at the office without losing access to your files, applications, and e-

mail.

With Multicast Server, you can connect to your work computer from home and access all

of your programs, files, and network resources as though you were actually sitting in

front of your computer at work.

Multicast Server Connection, available for most 32-bit versions of Windows including

Windows Mobile and Apple's Mac OS X, that allows a user to connect to a server

running Terminal Services. On Windows, both Terminal Services client and Multicast

Server Protocol use TCP port 3389 by default. It also includes a control to embed the

functionality in other applications or even a web page. Server versions of Windows OSs

also include the Multicast Server for Administration client (a special mode of the

Multicast Server Connection client), which allows remote connection to the console of

the server, where all command line applications can be run. The server functionality is

provided by the Terminal component, which is able to handle Remote Assistance,

Multicast Server as well as the Remote Administration clients.

LANGUAGE INTRODUCTION

SOFTWARE FEATURES

VISUAL BASIC.NET

Visual Baic.Net has revolutionized windows programming windows programming and

with an object based, event driven approach to software designs. Visual basic.Net

applications act as a front end to the database. Visual basic.Net application provides the

interface between the user and the database. Sophisticated features that make the

language truly object oriented and interfaces it with the latest in the database technology.

.NET provides a new, object-oriented API as a set of classes that will be accessible

from any programming language. This book describes this framework of classes and

provides a reference to what is available and how you can use this framework to write

Windows applications in the brave new world of .NET.

Microsoft .NET Framework is a computing platform for developing distributed

applications for the Internet. Following are the design goals of Microsoft .NET

Framework:

1. To provide a very high degree of language interoperability

2. To provide a runtime environment that completely manages code execution

3. To provide a very simple software deployment and versioning model

4. To provide high-level code security through code access security and strong type

checking

5. To provide a consistent object-oriented programming model

6. To facilitate application communication by using industry standards such as

SOAP and XML.

7. To simplify Web application development


4/61

Visual basic.net lets the user to add menus, text boxes, command buttons, option

buttons, check boxes, list boxes, scroll bars, and file directory boxes to blank windows.

Visual basic.net has many different tools.

The Common Language Runtime

The CLR is the mechanism through which .NET code is executed. It is built upon a

single, common languageILinto which source languages are compiled and includes

mechanisms for executing the compiled code. This includes code verification and just-in-

time (JIT) compilation, garbage collection and enforcement of security policies, and the

provision of profiling and debugging services.

The CLR provides a lot of added value to the programs it supports. Because it controls

how a .NET program executes and sits between the program and the operating system, it

can implement security, versioning support, automatic memory management through

garbage collection, and provide transparent access to system services

IMPORTANT FEATURES:

The application is a graphical user interface.

Client-Server architecture benefits picture and image box can be

easily handled using bit mapped files and icons. Bit mapped files and icons are used as simple debugging tools.

With the advent of .NET, Microsoft has introduced many new

technologies that make writing component-based distributed

systems easier, more flexible, and more powerful than ever before.

It is now easier than it has ever been to write components in any

programming language that can interoperate with components on

other machines, which may not be Windows-based at all.

Modules: Remote desktop

File and data transfer

Applications

Remote desktop:

This module helps in capturing the remote desktop at runtime. This module helps

in monitoring the remote system.

File and Data Transfer

File transfer

This module helps in transferring file to remote desktop by sending current ip address of

the system. File need to be send will have to give ip and files are send from server to

client system

Data transfer:

This is similar to above process except datas are send to the remote system.

Applications

This module helps in performing applications like logging of the remote

system, restarting the remote system, accessing applications like notepad, paint,

calculator, internet facilities.

8. SYSTEM DESIGN

System design is the process of planning a new system to complement or altogether

replace the old system. The purpose of the design phase is the first step in moving from

the problem domain to the solution domain. The design of the system is the critical aspect

that affects the quality of the software. System design is also called top-level design. The

design phase translates the logical aspects of the system into physical aspects of the

system.

INPUT DESIGN

Input design is one of the most important phase of the system design. Input design is

the process where the input received in the system are planned and designed, so as to get

necessary information from the user, eliminating the information that is not required. The

aim of the input design is to ensure the maximum possible levels of accuracy and also

ensures that the input is accessible that understood by the user.

The input design is the part of overall system design, which requires very careful

attention. if the data going into the system is incorrect then the processing and output willmagnify the errors.

The objectives considered during input design are:

Nature of input processing.

Flexibility and thoroughness of validation rules.

Handling of properties within the input documents.

Screen design to ensure accuracy and efficiency of the input

relationship with files.

Careful design of the input also involves attention to error

handling, controls, batching and validation procedures.

Input design features can ensure the reliability of the system and produce result from

accurate data or they can result in the production of erroneous information. The input

design of the system includes the following

OUTPUT DESIGN

Output design is very important concept in the computerized system, without reliable

output the user may feel the entire system is unnecessary and avoids using it. The proper

output design is important in any system and facilitates effective decision-making.

The output design of the system includes the following

TESTING AND IMPLEMENTATION

TESTING

Testing is a series of different tests that whose primary purpose is to fully

exercise the computer based system. Although each test has a different purpose, all work

should verify that all system element have been properly integrated and performed

allocated function. Testing is the process of checking whether the developed system

works according to the actual requirement and objectives of the system.

The philosophy behind testing is to find the errors. A good test is one that has a

high probability of finding an undiscovered error. A successful test is one that uncovers

the undiscovered error. Test cases are devised with this purpose in mind. A test case is a

Advantage:

Network security

Data loss is prevented

CONCLUSION:

This project helps in preventing all unauthorized users accessing the information . Data

loss is minimized. All operation is controlled in server side. Locking operation is

performed in server side which locks the client system . Once locked no operation is

performed on client side. Loss is prevented. Network locking is carried out in application

to prevent network intruders.
