કોઇ વેબસાઇટ પર રાઇટ ક્લિક ડિસેબલ હોય અને ટેક્સ્ટ કૉપી ન થતા હોય તો કઇ રીતે કરવા ? 

અમુક વેબસાઇટ દ્વારા કોઇ ડેટા કૉપી ન થઇ શકે તેવા ઉદેશ્યથી રાઇટ ક્લિક ડિસેબલ કરવામા આવે છે તેમજ ટેક્સ્ટ પણ સિલેક્ટ ન થઇ શકે તે પ્રકારની વ્યવસ્થા કરવામા આવે છે. મિત્રો, આ પ્રકારની વ્યવસ્થામા કઇ ખાસ હોતુ નથી, ફક્ત JavaScript નો જ ઉપયોગ કરવામા આવ્યો હોય છે. તેથી જો વેબ બ્રાઉઝરમા JavaScript ડિસેબલ કરી દેવામા આવે તો તે વેબસાઇટ પરની જે-તે સ્ક્રિપ્ટ કાર્ય કરી શકતી નથી અને યુઝરને રાઇટ ક્લિક કરવાની તેમજ ટેક્સ્ટ સિલેક્ટ કરવાની મંજુરી મળી જાય છે. 

આશા છે વિદ્યાર્થીઓને આ માહિતી ઉપયોગી થશે. 

Google Chrome:

• વેબસાઇટ લખવાની જગ્યા પર chrome://settings/content લખી Enter કી પ્રેસ કરવી
• ત્યારબાદ જે વિન્ડો ખુલે તેમા Do not allow any site to run JavaScript ઓપ્શન સિલેક્ટ કરવુ
• OK ક્લિક કરી બધી વિન્ડો બંધ કરવી.
• જે વેબસાઇટમા રાઇટ ક્લિક ડિસેબલ હોય તે વેબસાઇટ ખોલવી. જો પહેલેથી ખુલી જ હોય તો F5 કી દબાવી પેજ રીફ્રેશ કરવુ.

Mozilla Firefox:

• મોઝીલા ફાયરફૉક્સ વેબબ્રાઉઝરના Tools મેનુમા જઇ Options મેનુમા જવુ
• ત્યારબાદ જે વિન્ડો ખુલે તેમા Content મેનુ પસંદ કરવુ
• જે પેઇજ ખુલે તેમા Enable JavaScript ઓપ્શન પર સિલેક્ટ થયેલ હોય તેને હટાવવુ
• OK ક્લિક કરી બધી વિન્ડો બંધ કરવી
• જે વેબસાઇટમા રાઇટ ક્લિક ડિસેબલ હોય તે વેબસાઇટ ખોલવી. જો પહેલેથી ખુલી જ હોય તો F5 કી દબાવી પેજ રીફ્રેશ કરવુ.

Internet Explorer:

• Tools મેનુમા જઇ Internet Options મેનુ પસંદ કરવુ
• ત્યારબાદ Security ટેબ પસંદ કરી Custom Level બટન પર ક્લિક કરવુ
• ત્યા આપેલ લિસ્ટમાથી Scripting ઓપ્શન પસંદ કરી તેને Disable કરવુ
• બ્રાઉઝર બંધ કરી ફરીથી ચાલુ કરવુ અને  જે વેબસાઇટમા રાઇટ ક્લિક ડિસેબલ હોય તે વેબસાઇટ ખોલવી.

ઉપરની વિધિ કર્યા બાદ તમે કોઇપણ વેબસાઇટ પર રાઇટ ક્લિક કરી શકશો તેમજ ટેક્સ્ટ સિલેક્ટ કરી અને કૉપી-પેસ્ટ પણ કરી શકશો.

What is html?

what is HTML ?
HTML stands for the Hypertext Markup Language. It was defined by Tim Berners-Lee in 1990 as the method of marking up pages of information to be looked at by a browser. The Standard Generalized Markup Language (SGML) had been used widely at CERN for documentation and HTML was a cut down version of the CERN documentation language. HTML is not a static language and has gone though a number of iterations over the last 10 years: was the first real standard definition for core HTML features based upon current HTML 2.0 practice in 1994. W3C's first Recommendation for HTML and was defined in 1996.HTML 3.2 added tables, applets, text-flow around images, superscripts and subscripts, and was compatible with HTML 2.0. was first released as a W3C Recommendation on 18 December 1997. HTML 4.0 was released on 24th December 1999 and fixed a number of bugs in the HTML 4.0 and then HTML 4.01 specification is a reformulation of HTML 4 in XML and was released on 26 January 2000. 
There are certain advantages to the Web, such as multimedia, interactivity, timeliness, and a certain air of "tech awareness" that make creating HTML pages something of a necessity for businesses and a good idea for families, too. There are disadvantages as well, including the cost in time and money, the learning curve for Web design, and the constant need to update. 
HTML has been forced to evolve over the last year because of the involvement of millions of people, larger businesses, and commercial artists. Spearheaded by Netscape Navigator, a number of extensions to HTML for page-layout purposes have confused the mission of the Web. As a designer, it's up to you to decide who your audience will be and the most appropriate flavors of HTML to use in order to reach that audience. 


Advantages of HTML

Advantages and Disadvantages of the Web Most small or large businesses have a compelling reason to create a presence on the World Wide Web. It's an important new medium for communication that is relatively inexpensive to implement, it's a boon for dealing with customer service issues, and it's gaining popularity in leaps and bounds. But any good HTML designer should realize that there are also certain disadvantages to the Web. Advantages There are many good reasons to commit to creating a presence on the World Wide Web. Most of these are geared toward businesses, but you'll notice that these advantages are available to any Web site: 
Multimedia presentation-A Web site allows you to do things that are simply not possible in any other medium. With some of the visual impact of television, the informational utility of print, and the personal appeal of radio, the Web is an effective tool for taking marketing information to another level. Products can be explained and offered in depth, along with pictures, video, sound, and even animation. 
Interactivity-There are a number of different areas where the fact that your user can interactively determine what to view or hear can really make the difference for a business. Especially important is the added value the Web gives you for customer service, technical or product support, and immediate feedback. While most of any Web site is automated, it gives you an 
Opportunity to answer frequently asked questions and point customers to resources that may help them solves problems on their own. While this may seem like an advantage reserved for computer companies, consider the implications for service-oriented industries like travel, consulting, catalog sales, and business-to-business sales. 
Flexibility-If your business relies on printing or publishing as a medium, you may immediately see the advantage of the Web. Changes on the Web are relatively instantaneous, and the speed with which an update can be made is measured in minutes, not weeks. Consider the financial planner's or real estate agent's sales newsletter. Instant changes on the World Wide Web give their Net-savvy clients a time-based edge. Incorporating the Web into the services you offer a client gives you an added value in their eyes, especially in time-sensitive industries. 
Easy High-Tech-Whether you're a small or large business, it's important to keep up with technology in order to satisfy customers and be up on the "latest." Web pages are moving toward a point where they'll be expected of large businesses and not unusual from small ones. Like e-mail a couple years ago, and fax machines before that, it's become important to keep up with the Web. Fortunately, it's also rather easy to get started with HTML and quickly develop a Web site. 

The current state of HTML

With these commercial demands, however, have come different solutions. For every extension Netscape adds to HTML, there is generally (eventually) a standard agreed to by the World Wide Web Consortium (W3C) that meets the same need. Unfortunately, the implementation isn’t always the same. So, it's possible for an HTML 4.0 level standard, for instance, to provide for exactly the same layout functions as Netscape-but do it in a way that isn’t compatible with Netscape's browser. So HTML is currently in a bit of a flux. The best you can hope for is that the HTML standard is agreed upon and maintained more quickly in the future as more ideas pop up. At the same time, it's important that the standard remain well thought-out, and that it isn't allowed to become bloated and unworkable. In fact, this is probably the justification for recent changes to the standards bodies. With the W3C taking control of HTML, it suggests a shift in the ultimate power over HTML to the corporate players. From now on, you can probably assume that HTML extensions beyond what is generally considered HTML 3.0 will become standard on a case-by-case basis. Overall, this is probably a good thing, since standards can be agreed on as technology emerges-and competing browsers can all use the same methods to incorporate new technology.

<?php

$doc = new DOMDocument();

$doc->load( 'report.xml' );



$Record = $doc->getElementsByTagName( "Record" );

foreach( $Record as $rec )

{

$ccode = $rec->getElementsByTagName( "CCode" );

$ccode= $ccode->item(0)->nodeValue;



$destination = $rec->getElementsByTagName("DESTINATION");

$destination = $destination->item(0)->nodeValue;



$airwaybill = $rec->getElementsByTagName("AIRWAYBILL");

$airwaybill = $airwaybill->item(0)->nodeValue;



$awb = $rec->getElementsByTagName("AWB");

$awb = $awb->item(0)->nodeValue;



$SUB = $rec->getElementsByTagName( "SUB" );

$SUB = $SUB->item(0)->nodeValue;





$date = $rec->getElementsByTagName( "DATE" );

$date = $date->item(0)->nodeValue;

$time = $rec->getElementsByTagName( "TIME" );

$time = $time->item(0)->nodeValue;



echo "$ccode - $destination - $airwaybill - $awb - $SUB - $date - $time <BR>";

}

?>

connect with ms-access and print the table of data in php

<?php

$db_conn = new COM("ADODB.Connection");

$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=". realpath("thedata.mdb").";";

$db_conn->open($connstr);

if($db_conn)

{

echo "connected";

}

else

{

echo "not conected";

}

$rS = $db_conn->execute("SELECT * FROM main1");

$cnt=0;

echo"<table>";

while (!$rS->EOF)

{



if($cnt%2 == 0 )

{

print "<tr bgcolor='#C0C0C0'><td>".$rS->Fields(0)."</td><td>". $rS->Fields(1)."</td><td>".$rS->Fields(2)."</td><td>".$rS->Fields(3)."</td><td>".$rS->Fields(4)."</td><td> ".$rS->Fields(5)."</td><td>".$rS->Fields(6)."</td></tr>\n";

NETWORK SERVICES

NETWORK SERVICES

FILE SERVICES
1. It allows network users to share files using file server for providing this kind of services.
2. File services are network applications that store retrieve and move the data with the help of network file server.
3. User can read write and manage files with in this server.
PRINT SERVICES
1. Print servers are used to provide that kind of print services
2. This service also allows multiple and simultaneous printing access facility.
3. Network software uses printing queues which has special storage area where print jobs are stored and then sent to the printer in organized manner.
1. Jobs in print queues may be forward in order to receive the print according to the priority.
2. Printer can be placed anywhere in network and nay network users can use the printer.
3. The data sent by the user is transfer to the network printer at network speed.
4. Another print service is fax service it can be used for communication purpose.
5. In this services user can fax from its own work station to any other fax machine.
6. A fax machine can also work as sharing device in computer network.
COMMUNICATION SERVICE
1. Communication server handles data flow between numbers of networks.
2. It also handles the incoming and outgoing remote user and internet traffic.
3. Windows NT domain controller works as communication server.
SECURITY SERVICE
1. Security starts with the login procedures to ensure that a user who is accessing the network is using its password so, that only authorized users can log on to the network.
1. Login restrictions can force the user to login from a specific station and during a specific time.
2. Administrative tools can be used for security service in network operating system.
DATABASE SERVICE
1. Database services are provided by the data server
2. This service can provide networking with powerful database handling capabilities.
3. Most database systems are based on client server architecture so that database application can run on separate components.
1. The client side it provides the interface and handles less intensive functions line data request.

What is Network?

What is network?

An interconnected computer systems and also peripherals and devices with the purpose of data communication and information exchange are call network.
Or 
Connecting one or more than one computer to each other in such a way that they can share their hardware and software resources called network. 
Objectives of network:-
• Using network facilities we can share hardware like cd-drive, printer and other memory devices
• Network provides security to data files.
• Faster data communication without using external memory.
Components of network:-
1. NIC [ Network Interface Card ]
• A chip based circuit board used to connect computer to network or server
• A card is activities by installing it’s driver software
• A card is connect to I/O bus in a vacant slot
• The card contains physical interface for connectivity between computer’s internal and external resources
2. HUB
• A network device where the information flow is accumulated and then distributed various groups and users.
• It can be used between users on the same to LAN and the users on different LAN also [local area network].
• It serves as the central point where cables from all nodes come together.
• HUBs are available in different shapes and size it also provides limited management facility
• Dumb Hub (passive hub):- this type of hub only use for the data communication and there is no management facility.
• Intelligent Hub (Active hub);- this type of hub used for communication and also decision making it also has management facility.

3. Bridge
• A device that supports LAN to LAN communication is bridge.
• It will remember all the network addresses on both side of LANs and regulate the flow of traffic.


4. Router
• Router interconnects two or more physical and logical network and work at network layer.
• It distinguishes data packets according to protocol like, TCP/IP, FTP, HTTP etc.
• It will remember matrices to determine the optimal path of workstation in computer network.

5. Gateway
• A shared connection between LAN and a larger system such as mainframe computer or a large packet switching network whose communication protocols are different.
• It usually is slower than bridge or a router, it is a communication of hardware or software.
• It has its own processor and memory used to perform protocol conversion.

6. SERVER
• A server is an important component of a dedicated server network.
• The server runs on network operating system and offers network services to users at their individual workstation.
• These services include file storage securing, users management, network commands and many things.
• The most common type of server is file server
• When client computer send request to server , server will give respond to that computer.

7. Workstation
• When computer connect to a network it becomes a node on the network and is called a work station or client.
• It has its own local operating system e.g. DOS, win 98, win XP.
• Its job is to execute program files retrieved from the network and the server’s job is to deliver those files to the work station.

8. Cabling system
• In network cabling system is a media used to connect server and network station together.
• In case of wireless network that uses radio or infrared technology where cables are not required.
• There is several kind of cables used in networking like twisted pair cable, coaxial cable, fiber optics cable.

Advantages of networking:-
1. File sharing
2. Resource sharing
3. Database sharing
4. Creation of workgroup using user management facility
5. Centralized management system.
6. Provide security in corporate structure.
7. Ability to use network software.
8. Ability to use e-mail.

PUBLIC TELEPHONE NETWORK

PUBLIC TELEPHONE NETWORK

PUBLIC TELEPHONE NETWORK
1. Communication must occur between distinct point but few organization can justify the cost required.
2. LAN is characterized by high bandwidth and that company controls and maintain all the connectivity of devices as well as the transmission media (wire).
3. The company could have transmission media like infrared or satellite communication to establish connectivity.
4. Another possibility is different kind of cables can be used for connectivity
5. A variety of commercial options are available that enable organization to pay per only the level of service they require.
It has two main types
.
1. PSTN [PUBLIC SWITCHED TELEPHONE NETWORK]
1. This commercial network has its own existing infra structure supplied by the Telephone Company or Cable Company.
2. The feature of PSTN is its low speed, analog nature of transmission, a restricted bandwidth and also wide spread availability.
3. It is designed for telephone network but if we want it for digital communication than modem is required.
4. When the link setup is unreliable and can terminate without warning.
5. At that time PSTN communication medium is advisable.
6. This connects are easy to get at short notice. This is widely available and covers almost every location where people live and work.
7. PSTN is mostly useful for occasional users or as a backup to the private services
8. Fax machines can also operated in this network.
2. PSDN [PUBLIC SEITCHED DIGITAL(DATA) NETWORK]
1. It covers number of technology available for public telephone network.
2. The main feature is its high level of reliable and high quality of connection.
3. They can support both low and high speed at appropriate cost.
4. It can also use to link computer and system and network of one organization to several other organizations.
