SVN (SUBVERSION) A VERSION CONTROL SYSTEM

Posted by amit_vats
at November 24, 2008

HELLO FRIENDS,
This article will provide you a basic idea about SVN (Subversion) .

!!Have a GOOD TIME!!

———————————————————————————————–

—>SVN (SUBVERSION)<—

Subversion is a software for version control which is widely used to maintain current and historical versions of files such as source code, web pages, and documentation t.e this software control the progress of the source code files or any other data which is related to development of the software. Basically we can say that SVN keeps track of each and every change to the source files related to the software for which we are using the SVN software.

The following list is the capabilities of Subversion:

1. Controls the program version
2. Allows programmers from over the world working together in a single project
3. Simplify the distribution of source code
4. Detect the changes of source code
5. Possible to revert the current source code to the certain position of revision if(the revision no. is known).

If a programmer has finished the part of the software, He/she can “commit” or “update” the change of the code to the server. Using client Subversion software like Tortoise SVN, other programmers(as SVN provides multiuser support) are able to observe the latest change of the software, who change the part of source code and which part of source code were changed. All the files are kept in a “Repository”.(sample path: file:///C:/database)

—-> Creating a “Repository” using Tortoise SVN in windows xp/vista<—-

1. Open the windows explorer

2. Create a new folder and name it eg. “database”

3. Right-click on the newly created folder and select TortoiseSVN ? Create Repository here….

A repository is then created inside the new folder name “database”. We can import project files in the repository once it is created by using the import command.

“Import” —> command is used to import the contents of a project or application (file and folders) to the Repository.

—>To import a project folder to the repository right click on the top level repository folder in windows explorer to open the context menu

1>Select the command TortoiseSVN

2> Select “Import” which brings up a dialog box for you to enter the URL of the repository into which you want to import your project.( eg C:\FileZilla FTP Client)

3>press OK to imports the complete directory tree including all files into the repository.(eg. C:\Project)

—- > The most important commands that are widely used when a SVN software is used are “Update and Commit”.

—->Update command<—-

The update command is used to receive changes that the other users have made to a particular file or folder in the repository and have committed to the server repository. “Update” will get the latest changes and automatically merge any changes from the server with your code.

—->Steps to update a file or folder<—–

1> we need to right click on the file or folder to open the SVN context menu which is shown above(figure) containing several options such as commit, update etc.

1> select the “Update” option to commit the changes made to the file.

2>A dialog box appears that let’s you quickly see all the files that are going to be updated.

3> press OK button to Update the selected files and folders.

—->Commit command< —-

The “commit” command is used to update your changes to the Subversion server. Commit is a command to send latest update of all the users source code(the files which were accessed and edited) to the repository server.

—> To commit the changes to a file we need to access the repository file or folder on which changes are made. Steps to commit a file are

1> we need to right click on the file or folder to open the SVN context menu which is shown above containing several options such as commit, update etc.

1> select the “commit” option to commit the changes made to the file.

2>You’ll get a dialog that let’s you quickly see all the files that are going to be updated by the commit.

3> press OK button to commit the selected files and folders

—>You can use Tortoise SVN in explorer any time to see any changes that have been made to files. Any changed files will show with as a “Red” warning icon which means you’ve made changes to the file that haven’t been updated onto the server. The red icons appear next to files as well as folders. Note that the red icon does not tell you whether the file has been changed by anybody else! It only tells you that you have changed the file and need to commit it.

——> SVN is widely used to maintain current and historical versions of files such as source code, web pages, and documentation.

Introduction to AJAX Technology

Posted by amit_vats
at November 16, 2008

Hello Friends ,

This article will provide you basic information about AJAX Technology.

———————————————————————————————

—-> AJAX TECHNOLOGY —<

Ajax (sometimes called Asynchronous JavaScript and XML) is a way of programming for the Web that gets rid of the hourglass. Data, content, and design are merged together into a seamless whole. When your customer clicks on something on an Ajax driven application, there is very little lag time. The page simply displays what they’re asking for. Try out Google Maps for a few seconds. Scroll around and watch as the map updates almost before your eyes. There is very little lag and you don’t have to wait for pages to refresh or reload.

What is Ajax?

Ajax is a way of developing Web applications that combines:

In the traditional Web application, the interaction between the customer and the server goes like this:

1. Customer accesses Web application

2. Server processes request and sends data to the browser while the customer waits

3. Customer clicks on a link or interacts with the application

4. Server processes request and sends data back to the browser while the customer waits

There is a lot of customer waiting.

Ajax Acts as an Intermediary

The Ajax engine works within the Web browser (through JavaScript and the DOM) to render the Web application and handle any requests that the customer might have of the Web server. The beauty of it is that because the Ajax engine is handling the requests, it can hold most information in the engine itself, while allowing the interaction with the application and the customer to happen asynchronously and independently of any interaction with the server.

Asynchronous

This is the key. In standard Web applications, the interaction between the customer and the server is synchronous. This means that one has to happen after the other. If a customer clicks a link, the request is sent to the server, which then sends the results back.

With Ajax, the JavaScript that is loaded when the page loads handles most of the basic tasks such as data validation and manipulation, as well as display rendering the Ajax engine handles without a trip to the server. At the same time that it is making display changes for the customer, it is sending data back and forth to the server. But the data transfer is not dependent upon actions of the customer.

MVC (MODEL VIEW CONTROLLER) MODEL FOR SOFTWARE DEVELEPMENT

Posted by amit_vats
at November 16, 2008

 Hello friends

                             This article will give you a basic idea about the MVC (MODEL VIEW CONTROLLER)  model.

                                                                               !@!HAVE A NICE TIME!@!..

 

                                  MVC (MODEL VIEW CONTROLLER)

Model View Controller (MVC) is an architecture for building a software or web applications that separate the data (model) from the user interface (view) and the processing (controller). Providing a programming interface between the data and the processing has been a primary concept in information technology for decades. MVC is widely used in Web-based application frameworks.  Very simply we can define MVC as

                                   The Basic MVC Model

 

Model

 

   — state data for each component.

 

·         Different for each component

 

·         E.g.    Scrollbar — Max and minimum Values, Current Position, width   of         thumb position relative to values

 

·         E.g.       Menu — Simple List of items.

 

·         Model data is always independent of visual representation.

 

View

 

– How component is painted on the screen

 

·         Can vary between platforms/look and feel (like linux, windows, mac etc)

 

Controller

 

 

– dictates how component interacts with events

 

·         Many forms of events — mouse clicks, keyboard, focus, repaint etc..

 

·         Controller decides how component reacts to an event .

 

 

main.JPG

 

                                        BASIC  MVC  OPERATION

 

–In the MVC paradigm the user input, the modeling of the external world, and the visual feedback to the user are explicitly separated and handled by three types of object, each specialized for its task. The view manages the graphical and/or textual output to the portion of the bitmapped display that is allocated to its application. The controller interprets the mouse and keyboard inputs from the user, commanding the model and/or the view to change as appropriate. Finally, the model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

 

It is important to note that both the view and the controller depend on the model. However, the model depends on neither the view nor the controller. This is one the key benefits of the separation. This separation allows the model to be built and tested independent of the visual presentation. The separation between view and controller is secondary in many rich-client applications, and, in fact, many user interface frameworks implement the roles as one object. In Web applications, on the other hand, the separation between view (the browser) and controller (the server-side components handling the HTTP request) is very well defined.

AREAS OF WEB DEVELOPMENT

Posted by amit_vats
at November 14, 2008

!!Hello Friends!!     This article will provide you basic information about various areas of development with technology point of view. I hope this article will provide help you to have a basic idea about the various key areas and latest technologies used for corresponding web development.

 Web development is a broad term for any activity related to developing a web site for the World Wide Web or an intranet. This can include e-commerce business development, web design, web content development, client-side/server-side scripting, and web server configuration.  Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services.

 —->  Web Developmet can be is widely used in both commercial and Technical areas such as

—> Web Development can be split into many areas but the most important part is the type of technologies used for web development for various areas.  Typical and basic web development hierarchy might consist of technical areas given below

                              —>Client Side Coding—<

This is code/routines that are not processed at all by the server. Code is written in scripts (Html,Javascript usually) - plain text commands that instruct the client to do something. Generally used for performing dynamic effects, such as image rollovers, or displaying message boxes, or even validation of data entered into a form (i.e. email address is in the format of an email address … contains the @ symbol). Some of the Client side development technologies are give below

————————————————————————————————————

                              —>Server Side Coding<—

This is code/routines that are  processed  by the server t.e the code is executed by the server and the changes are sent to the web browser. Code is written in scripts (PHP,Perl usually). Some of the server side development technologies are give below

                        —> Database Technology<—

Database is one of the most critical areas for web development. Some of the most popular database servers and Technologies  are given below   which are widely used for web development.

————————————————————————————————————

                                —-> LAMP   (Linix, Apache, MySql, PHP)<—

LAMP servers are the most popular setup used by the web development community for web development.

LAMP is an open source web application and development platform, mostly free for developing and deploying simple or complex database driven website on the server.  LAMP is the platform of choice for the rapid development in the global competitive market for deploying low-cost, reliable, scalable, secure web applications for small to large scale websites and web applications

LAMP is widely used by used by some of the fastest growing development firms like Eddytools (www.eddytools.org) .

All the above key technical areas and technologies which are widely used for website development hierarchy and can be extended to include all client side and server side aspects. It is still important to remember that web development is generally split up into client side coding covering aspects such as the layout and design, then server side coding, which covers the website’s functionality and back end systems .

Introduction to HTML/XHTML, CSS, Javascript and RDBMS

Posted by amit_vats
at November 12, 2008

Hello friend,  This tutorial will help you to have a brief idea about web development languages  like XHTML/HTML, CSS, JavaScript and RDBMS.   we will start with HTML      !!Have a Nice Time!!

——————————————————————————————–

                           

                   —>  Introduction to HTML<—

HTML stands for Hyper Text Markup Language. HTML is an application of Standard Generalized Markup Language (SGML)

It provides a means to describe the structure of text-based information in a document — by denoting certain text as links, headings, paragraphs, lists, and so on — and to supplement that text with interactive forms, embedded images, and other objects. HTML is written in the form of tags, surrounded by angle brackets( <,> ). HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded scripting language code (such as JavaScript) which can affect the behavior of Web browsers and other HTML processors. Some of the basic information about HTML is given below.

Type in the following text:

<html>
<head><title>Title of page</title>
 </head>

<body>

This is my first homepage. <b>This text is bold</b></body>

</html>

Save the file as “myfirstpage.htm”.

Start your Internet browser(I.E,Mozilla,Apache etc). Select “Open” (or “Open Page”) in the File menu of your browser. A dialog box will appear. Select “Browse” (or “Choose File”) and locate the HTML file you just created - “mypage.htm” - select it and click “Open”. Now you should see an address in the dialog box, for example “C:\MyDocuments\myfirstpage.htm”. Click OK, and the browser will display the page.

  —————————————————————————————–                         

                      

                        —>  Introduction to XHTML <—

                              

                                                                                                                                                                                                                                                                                                  The Extensible Hypertext Markup Language, or XHTML, is a markup language that has the same depth of expression as HTML, but also conforms to XML syntax.

While HTML is an application of Standard Generalized Markup Language (SGML), a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML. Because they need to be well-formed, true XHTML documents allow for automated processing to be performed using standard XML tools—unlike HTML, which requires a relatively complex, lenient, and generally custom parser. XHTML can be thought of as the intersection of HTML and XML in many respects, since it is a reformulation of HTML in XML. XHTML 1.0 became a World Wide Web Consortium (W3C) Recommendation on January 26, 2000. XHTML 1.1 became a W3C Recommendation on May 31, 2001. Some of the basic information about XHTML is given below.

——————————————————————————————-                     

                       —>  Introduction to CSS <—

Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTM. CSS can be used locally by the readers of web pages to define colors, fonts, layout, and other aspects of document presentation. Style sheets allow style information to be specified in many ways. Styles can be specified inside a single HTML element, inside the <head> element of an HTML page, or in an external CSS file. Even multiple external style sheets can be referenced inside a single HTML document.  Some of the basic information about CSS is given below.

For complete tutorial go to : http://www.w3schools.com/css/css_intro.asp

——————————————————————————————

                          
                           —>  Introduction to JavaScript<—

JavaScript is a scripting language widely used for client-side web development.                 It is a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but be easier for non-programmers to work with. JavaScript is used in millions of Web pages to improve the design, validate forms, detect browsers, create cookies, and much more. JavaScript is the most popular scripting language on the internet, and works in all major browsers, such as Internet Explorer, Firefox, and Opera.  Some of the basic information about XHTML is given below.

For complete tutorial go to :  http://www.w3schools.com/js/js_intro.asp

——————————————————————————————-

                       —>  Introduction to RDBMS (SQL)<—

A Relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E. F. Codd. Most popular commercial and open source databases currently in use are based on the relational model. RDBMS is the basis for SQL, and for all modern database systems like MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access. The data in RDBMS is stored in database objects called tables. A table is a collections of related data entries and it consists of columns and rows.

A short definition of an RDBMS may be a DBMS in which data is stored in the form of tables and the relationship among the data is also stored in the form of tables.

SQL (Strutured Query Language) is a database(RDBMS)  computer language designed for the retrieval and management of data in relational database management systems (RDBMS), database schema creation and modification, and database object access control management. SQL is a standard interactive and programming language for querying and modifying data and managing databases. The core of SQL is formed by a command language that allows the retrieval, insertion, updating, and deletion of data, and performing management and administrative functions.

SQL can be divided into two parts: The Data Manipulation Language (DML) and the Data Definition Language (DDL).

The query and update commands form the DML part of SQL:

The DDL part of SQL permits database tables to be created or deleted. It also define indexes (keys), specify links between tables, and impose constraints between tables. The most important DDL statements in SQL are:

Posted by admin
at August 5, 2008

Hi There,

if you stuck in finding the solution to find and replace your complex string then Dreamwever Regular Expression Find & Replace is the Answer to your solution.

in my case i have to find a function like

1) $sess->getSessVar(’user’);

2)  $sess->setSessVar(’user’,'akn’);

and Replace it with

1) $_SESSION['user'];

2)$_SESSION['user']=’akn’;

so i have to written the Regular exp as
FIND
\$sess->getSessVar\(’(.*)’\);
Replace
$_SESSION['$1'];

AND

Find
\$sess->setSessVar\(’(.*)’,(.*)\);
Replace
$_SESSION['$1']=$2;
