Diffrence between Website and WebApplication

Web application		Web site
1	In software engineering, a web application is an application that is accessed via a web browser over a network such as the Internet or an intranet.	A website  is a collection of related web pages, images, videos or other digital assets that are addressed relative to a common Uniform Resource Locator (URL).
2	A website is informational	A web application is interactive
3	In web application we have chance of select only one programming language during creation of project either C# or VB.NET.	In website we can create pages in multi programming languages that means we can create one page code in C# and another page code in vb.net.
4	We need to pre-compile the site before deployment.	No need to recompile the site before deployment.
5	If we make small change in one page we need to re-compile the entire sites.	If we make any code changes those files only will upload there is no need to re-compile entire site
6	Whenever we create Web Application those will automatically create project files (.csproj or .vbproj).	Web Sites won’t create any .csproj/.vbproj files in project
7	If we create any class files / functions those will be placed anywhere in the applications folder structure and it is precomplied into one single DLL.	If we create any class files/functions those will be placed in ASP.NET folder (App_Code folder) and it's compiled into several DLLs (assemblies) at runtime.
8	Right choice for enterprise environments where multiple developers work unitedly for creating,testing and deployment.	Right choice when one developer will responsible for creating and managing entire website.
9	Eg  They require you to  download. But still use your internet access	Eg

Jquery basics

What is jQuery?

• jQuery is a lightweight, "write less, do more", JavaScript library.
• The purpose of jQuery is to make it much easier to use JavaScript on your website.
• jQuery takes a lot of common tasks that require many lines of JavaScript code to accomplish, and wraps them into methods that you can call with a single line of code.
• jQuery also simplifies a lot of the complicated things from JavaScript, like AJAX calls and DOM manipulation.

The jQuery library contains the following features:

• HTML/DOM manipulation
• CSS manipulation
• HTML event methods
• Effects and animations
• AJAX
• Utilities

Why jQuery?

• There are lots of other JavaScript frameworks out there, but jQuery seems to be the most popular, and also the most extendable.
  Many of the biggest companies on the Web use jQuery, such as:
  
• Google
• Microsoft
• IBM
• Netflix

Adding jQuery to Your Web Pages

There are several ways to start using jQuery on your web site. You can:

• Download the jQuery library from jQuery.com

• Include jQuery from a CDN, like Google

What Are Packages?

What Are Packages?

A package allows a developer to group classes (and interfaces) together. These classes will all be related in some way – they might all be to do with a specific application or perform a specific set of tasks. For example, the Java API is full of packages. One of them is the javax.xml package. It and its subpackages contain all the classes in the Java API to do with handling XML.
Defining a Package

To group classes into a package each class must have a package statement defined at the top of its .java file. It lets the compiler know which package the class belongs to and must be the first line of code. For example, imagine you're making a simple Battleships game. It makes sense to put all the classes needed in a package called battleships:

package battleships

class GameBoard
{

}

Every class with the above package statement at the top will now be part of the Battleships package.

Typically packages are stored in a corresponding directory on the filesystem but it is possible to store them in a database. The directory on the filesystem must have the same name as the package. It's where all the classes belonging to that package are stored. For example, if the battleships package contains the classes GameBoard, Ship, ClientGUI then there will be files called GameBoard.java, Ship.java and ClientGUI.java stored in a directory call battleships.

String Function in Vb.net

Some String manipulation functions with example

1. Getting the length of a string or variable

            Dim StrText As String

            Dim r As Integer    

            StrText = "How long is this text?"

            r = StrText.Length

            MsgBox(r)

2. Getting the substring from a string or variable

            Dim r As String = "Welcome to the world"

            r = r.Substring(8)             

            MsgBox(r)

            Dim r As String = "Welcome to the world"

            r = r.SubString(8, 6)

            MsgBox(r)

3. If you wish to search the text for a particular word, then you will use the IndexOf(Find word, StartPosition) function.

Dim r As String = "The weather is warm and sunny"

r = r.IndexOf("warm")

MsgBox(r)

This code starts at the beginning of 'The weather today is reasonably warm and sunny', because we didn't give a start position, and searches for the word 'warm' in it. If it does not find the word warm in the string, then it will return the value as 0, and you get a message saying '0'. However, if it finds the word, then it returns a number saying where it found the start of the word. In this case, you would see a message box saying '16' because the 'w' of warm is 16 characters into the string.

4. Find and replace in a string

.Replace(search for text, replace with text) is used to search through a string, and replace certain words or characters with other ones. The Replace function returns the text that it has replaced.

            Dim i As String = "Only a fool goes outside in the rain"

            i = i.Replace("fool", "brave bloke")    

            MsgBox(i)
