`

four user controls are as follows: Explorer, SystemInfo, Services, and Processes. Each one of

these controls does its own specific task. Brief description of what each one of these control

does.

Explorer Control - we converted 'My Explorer' to a user control, it still display your

system drives, directories, and files information.

SystemInfo Control* - This control display operating system information and hardware

data and specifications.

Services Control* - This control display services currently running on the system.

Process Control* - This control display processes currently running on the system.

(* Note: This control can be used to monitor local or remote system on the network.)

Every one of these controls uses the System.Management namespace to access their own specific

system information.

Development Tool : VC#.NET

1.0 PROJECT DESCRIPTION

1.1 INTRODUCTION

Remote Desktop Connection (RDC, also called Remote Desktop, formerly known

as Microsoft Terminal Service Client, or mstsc) is the client application for Remote Desktop

Services. It allows a user to remotely log in to a networked computer running the terminal

services server. RDC presents the desktop interface of the remote system, as if it were

accessed locally The server should have the ability to minimize ,maximize or close those

applications on the client's desktop.

It should not follow RDP protocol or remote desktop protocol in windows xp

protocol.But it should be running in windows xp environment.

Both the systems should be working simultaneously and there should be no user

name and password conventions in this application.The application should simply work based

on the IP address and port number.

1.2 EXISTING SYSTEM:

The current system of WMI provided by the Microsoft will display the contents such as

processes, services and system information of the current machine. In the client server

environment the server can monitor the remote machine information such as system info,

processes and service, but the two different clients in the network cannot view the information of

one client from the other. In order to overcome this problem, a proposed system is devised based

on the functionality of the existing system. The proposed system is explained in the next section.

1.3 PROPOSED SYSTEM:

The proposed system is devised in order to overcome the defects of the existing system. In

the proposed system. The clients in the interconnected environment can view the information of

another client in the interconnected system. This functionality is made possible as follows, any

machine in the windows platform will have the default control named WMI, which is responsible

for fetching the computers information, thus the remote machine in the network also have the

WMI, thus we can call the remote machines WMI through the SNMP protocol, by doing so the

information of the remote client in the network can be accessed by another client.

Client A Client C

1.4 WIN-32 API

Win32 requires a good level of understanding and work, Microsoft released a

customized version of the Win32 library to make it easier to comprehend. The library is called

Microsoft Foundation Class Library (MFC). Because Win32 was written in C and MFC was

written for C/C++ developers, programmers of other languages would not understand it. To

accommodate others, in fact to make Windows programming accessible to everybody, Microsoft

13


14/73

`

created Microsoft Visual Basic as a true graphical programming environment. Visual Basic used

a different and simpler language, called Basic as its foundation.

1.5 Modules in Detail

In this project I have created a WMIControlLibrary which contains four user controls. The

four user controls are as follows: Explorer, SystemInfo, Services, and Processes. Each one of

these controls does its own specific task. Here is a brief description of what each one of these

control does.

Explorer Control - I converted 'My Explorer' to a user control, it still display your system

drives, directories, and files information.

SystemInfo Control* - This control display operating system information and hardware

data and specifications.

Services Control* - This control display services currently running on the system.

Process Control* - This control display processes currently running on the system. (*

Note: This control can be used to monitor local or remote system on the network.)

Every one of these controls uses the System.Management namespace to access their own specific

system information.

14


15/73

`

1.5.1 Explorer Control

In the Explorer control, I used the WMI Win32_LogicalDisk class to get all the local and

mapped drives on the local machine. To get access to drives information, I need to use the

ManagementObjectSearcher class to obtain a ManagementOjbectCollection class containing the

drive information.

I requested. We now have all the available drives' information at our disposal (such as drive

name, type, volume, description, etc...).

Unfortunately, it proved almost impossible to find any references to the interfaces

necessary to do the job.

15


16/73

`

1.5.2 SystemInfo Control

The SystemInfo control display many different types of information about your local machine or

a remote machine on the network. It first establishes a ConnectionOptions object with the

UserName and Password properties set. Then it creates a ManagementScope object with the

local or remote host name and the ConnectionOptions object as the parameters.

Now we are ready to access the system information by creating an ObjectQuery member object

and passing it along with the ManagementScope object in to the ManagementObjectSearcher

member object and invoke the Get() method to execute the command.

If you are only concerned about the local host information, you can avoid the creation of

ConnectionOption, ManagementScope, and ObjectQuery objects. All you need to do is just call

the ManagementObjectSearcher member object with the query string and execute the

ManagementObjectSearcher.Get() method to get the ManagementObjectCollection result back,

for the local machine.

16


17/73

`

The SystemInfo control also displays the following information about the computer system being

accessed: System Manufacturer, Processor, Bios, Time Zone, Memory, Network Connection,

and Video Controller. The codes for these different queries are repetitive, it's just the query string

and the result properties are different.

1.5.3 Service Control

The Service control uses the query:

SELECT * FROM Win32_Service

to retrieve all the services information in the system. To start or stop a service, I dynamically

create a popup menu to the ListView.

When you right click on an item, a start or stop menu pops up, depending on the service state.

When the MenuItem is clicked, I need to get the ManagementObject for that service with this

query.

17


18/73

`

SELECT * FROM Win32_Service WHERE Name = 'ServiceName'.

Then I call the ManagementObject.InvokeMethod() to start or stop the service. The first

parameter in the InvokeMethod method is the Observer parameter. I pass in a

ManagementOperationObserver class to manage asynchronous operations and handlemanagement information and events received asynchronously. By checking the returnValue

property in completionHandlerObj.ReturnObject, I can determine if the operation was successful

or not.

1.5.4 Process Control

The Process control display the system running processes, user that started the process, CPU

utilization, and memory usage.

To get the process user, I need to call the GetOwner(User, Domain) method. The User and

Domain parameters are output parameters. How do we get to these output parameters from

InvokeMethod.

18


19/73

`

This depends on how we implement the InvokeMethod. If we do not need to manage

asynchronous operations, then we need to pass in a string[] to the InvokeMethod method to

retrieve the output parameters.

But if we need to manage asynchronous operations, then we do not need to pass in any

parameters to InvokeMethod method. You will get the output parameters from the

completionHandlerObj.ReturnObject properties collection.

2.0 SOFTWARE DESCRIPTION

2.1 Visual Basic .NET

Visual Basic .NET provides the easiest, most productive language and tool

for rapidly building Windows and Web applications. Visual Basic .NET comes with enhanced

visual designers, increased application performance, and a powerful integrated development

environment (IDE). It also supports creation of applications forwireless, Internet-enabled hand-

held devices. The following are the features of Visual Basic .NET with .NET Framework 1.0 and

Visual Basic .NET 2003 with .NET Framework 1.1. This also answers why should I use Visual

Basic .NET, what can I do with it?

2.1.1 Powerful Windows-based Applications

Visual Basic .NET comes with features such as a powerful new forms designer, an

in-place menu editor, and automatic control anchoring and docking. Visual Basic .NET delivers

new productivity features for building more robust applications easily and quickly. With an

improved integrated development environment (IDE) and a significantly reduced startup time,

Visual Basic .NET offers fast, automatic formatting of code as you type, improved IntelliSense,

an enhanced object browser and XML designer, and much more.

2.1.2 Building Web-based Applications

With Visual Basic .NET we can create Web applications using the shared Web Forms

Designer and the familiar "drag and drop" feature. You can double-click and write code torespond to events. Visual Basic .NET 2003 comes with an enhanced HTML Editor for working

with complex Web pages. We can also use IntelliSense technology and tag completion, or

choose the WYSIWYG editor for visual authoring of interactive Web applications.

22/73

`

2.1.3 Simplified Deployment

With Visual Basic .NET we can build applications more rapidly and deploy and

maintain them with efficiency. Visual Basic .NET 2003 and .NET Framework 1.1 makes "DLL

Hell" a thing of the past. Side-by-side versioning enables multiple versions of the same

component to live safely on the same machine so that applications can use a specific version of a

component. XCOPY-deployment and Web auto-download of Windows-based applications

combine the simplicity of Web page deployment and maintenance with the power of rich,

responsive Windows-based applications.

2.2 Powerful, Flexible, Simplified Data Access

You can tackle any data access scenario easily with ADO.NET and ADO data

access. The flexibility of ADO.NET enables data binding to any database, as well as classes,

collections, and arrays, and provides true XML representation of data. Seamless access to ADO

enables simple data access for connected data binding scenarios. Using ADO.NET, Visual

Basic .NET can gain high-speed access to MS SQL Server, Oracle, DB2, Microsoft Access, and

more.

2.2.1 Improved Coding

You can code faster and more effectively. A multitude of enhancements to the

code editor, including enhanced IntelliSense, smart listing of code for greater readability and a

background compiler for real-time notification of syntax errors transforms into a rapid

application development (RAD) coding machine.

2.2.2 Direct Access to the Platform

Visual Basic developers can have full access to the capabilities available in

.NET Framework 1.1. Developers can easily program system services including the event log,

performance counters and file system. The new Windows Service project template enables to

build real Microsoft Windows NT Services.

22
http://www.startvbdotnet.com/dotnet/vbnet.aspxhttp://www.startvbdotnet.com/dotnet/vbnet.aspx


23/73

`

Programming against Windows Services and creating new Windows Services is not available in

Visual Basic .NET Standard, it requires Visual Studio 2003 Professional, or higher.

2.2.3 Full Object-Oriented Constructs

You can create reusable, enterprise-class code using full object-oriented

constructs. Language features include full implementation inheritance, encapsulation, and

polymorphism. Structured exception handling provides a global error handler and eliminates

spaghetti code.

2.3 XML Web Services

XML Web services enable you to call components running on any platform

using open Internet protocols. Working with XML Web services is easier where enhancements

simplify the discovery and consumption of XML Web services that are located within any

firewall. XML Web services can be built as easily as you would build any class in Visual Basic

6.0. The XML Web service project template builds all underlying Web serviceinfrastructure.

2.3.1 Mobile Applications

Visual Basic .NET 2003 and the .NET Framework 1.1 offer integrated support

for developing mobile Web applications for more than 200 Internet-enabled mobile devices.

These new features give developers a single, mobile Web interface and programming model to

support a broad range of Web devices, including WML 1.1 for WAPenabled cellular phones,

compact HTML (cHTML) for i-Mode phones, and HTML for Pocket PC, handheld devices, and

pagers. Please note, Pocket PC programming is not available in Visual Basic .NET Standard, it

requires Visual Studio 2003 Professional, or higher.

2.3.2 COM Interoperability

You can maintain your existing code without the need to recode. COM

interoperability enables you to leverage your existing code assets and offers seamless bi-

directional communication between Visual Basic 6.0 and Visual Basic .NET applications.

24/73

`

2.3.3 Reuse Existing Investments

You can reuse all your existing ActiveX Controls. Windows Forms in Visual

Basic .NET 2003 provide a robust container for existing ActiveX controls.

In addition, full support for existing ADO code and data binding enable a smooth transition to

Visual Basic .NET 2003.

2.3.4 Upgrade Wizard

You upgrade your code to receive all of the benefits of Visual Basic .NET 2003. The Visual

Basic .NET Upgrade Wizard, available in Visual Basic .NET 2003 Standard Edition, and higher,

upgrades up to 95 percent of existing Visual Basic code and forms to Visual Basic .NET with

new support for Web classes and User Controls.

3.0 TESTING OBJECTIVES

Testing is a process of executing a program with an intense of finding an error. A

test is on that has a high probability or finding an undiscovered errors. A successful test is

that uncovers an undiscovered errors.

3.1 TYPE OF TESTING DONE:

As per seven laws of computing Any non-trivial program contains at least one

bug. These are no trivial programs. The proper choice of test data is an important as the

test itself so; live data has been collected for testing.

3.1.1 UNIT TESTING:

The modules of the system are tested as an individual in unit testing; each unit has

definite input and output parameters.

3.1.2 INTEGRATION TESTING:

In the system testing, the system is tested as a whole intercommunication, among

the individual units and functions of the complete system are tested.

3.1.3 SYSTEM TESTING:

In the system testing, the system is tested as a whole intercommunication, among

the individual units and functions of the complete system are tested.

3.1.4 DESTRUCTION TESTING:

In this type of testing, the application is tested until it does something. A is not

suppose to do.

3.1.5 WINDOWS DESIGNING TEST:

This test provides, that each individual window (print, record, menus, message box) that

the system consists of has been designed and built according to project standards.

26


27/73

`

3.1.6 FUNCTION TESTING:

This testing method ensures that the nuts and bolts functions of the system are

actually tested.

3.1.7 INTEGRATION TESTING:

The aim of the integration test is to put together the individually unit tested pages

and build program structure; while at the some time tests are conducted to uncover errors

associated with interfacing of pages.

In this test this program goes smoothly from starting end. If we give any wrong

input it display error message immediately. Display output are tested and verified.

3.1.8 PERFORMANCE TESTING:

This determines the length of time by the system to process transaction of data.

For ex, the response times in case of an inquiry of the system

Implementation is the stage where the theoretical is converted into a working

system. This is the processing converting a new or a revised system into an operational

one of the implementation consists of

Testing the developed system with sampled data.

Detection and correction of errors.

Making necessary charges in the system.

Checking of reports with that of the existing system.

Training of software and hardware utilities.

Installation of software and hardware utilities

4.0 IMPLEMENTATION ON CLIENT MACHINE(Graphically)

4.1 User Password

In order for remote desktop to work, you have to set a password on your user account. Follow

these steps to set a password.

1. Go to Start then to My Computer (or go to your desktop and go to My Computer)

2. Go to Control Panel

3. Go to User Accounts

4. Click on your user account

5. Go to Create a Password

6. Fill everything out and hit Create Password

4.2 Enabling Remote Desktop Connection (on the host)

Now youre ready to enable remote desktop. You have to be logged in as an administrator

1. Go to Start then right click on My Computer (or right click My Computer on your

desktop)

29


30/73

`

2. Select Properties

3. Go to the Remote tab

4. Check Allow users to connect remotely to this computer

5. If you have other users that you want to allow remote access to the computer then go to

Select Remote Users and select add and type in the user account name of the user where

it says Enter the object names to select

4.3 Getting your IP address

You now have to get your ip address.

4.3.1 Connecting to the host machine from another machine

Now, this is how to connect to your computer from using Remote Desktop Connection. If youre

using a computer that doesnt have Windows XP then you can load the client side of Remote

Desktop Connection. Get it at and then you can follow these steps.

1. Go to Start

2. Go to All Programs

3. Go to Accessories

4. Go to Communications

5. Click Remote Desktop Connection

6. Go to Options and modify the options as you seem fit

7. Type in your IP address by 'Computer'

8. Log in with your username and password

You should now have access to your computer. Take note that playing music will not work well

with over the remote connection unless you have it stay at the local computer (change this in the

options). Also, if you view images and webpages over the connection it will be very slow. Oh,

and of course, you cant play games like Quake 3 over the connection, this simply isnt possible.

You can access your documents from anywhere.

30


31/73

`

You can keep your IRC (internet relay chat) and IM clients open on one machine and

then connect to your computer from other places. Thus you dont have to leave your

screen names and whatnot behind on other peoples computers.

Check and save email in YOUR email client instead of using webmail.

Perhaps your workplace/school doesnt allow you to run IRC or IM clients, but you can

use remote desktop. Then you can log on to your computer and IRC and IM from there.

You could use this as some sort of tech support method.

You can use Remote Desktop if you cant always have a monitor plugged in to the box.

Great for servers, you don't need to buy keyboard, mouse, monitor etc. to use.

4.4 Cons

You cant play games with it.

Images lag the connection.

In order to start the server you have to log into your account, meaning if youre on

vacation and your computer locks up, youll have to have someone else reboot the

computer and log in with your password. But this problem can be fixed by modifying a

DLL file and adding a registry value. And up to 2 more computers can be connected

remotely at the same time.
