Windows Presentation Foundation [WPF]

Introduction to WPF

WPF is Windows Presentation Foundation,it also introduced in Dotnet 3.0 and higher versions..It is a next generation of presentation system for building desktop [standalone] and web browser applications.

In this we are using one type of namespace is

using System.Windows;

WPF programming is similar to dotnet programming like classes,properties,methods and event handlings.this programming language is in either c#.net or vb.net.

Features:

XAML [Extensible Application Markup Language]

Layouts - controls

Animations --- 2-D, 3-D Graphics

Documents --- Styles,Templates

How to Build Web Application using Asp.Net

Web Application using asp.net with c#.net

A Web Form is an asp.net technology that we use to create a programmable web page,and we can use code on the server to impliment application logic.

Features

This Web form run on a various browsers automatically render the browser compliant html it is built on the CLR(Common Language Runtime) .

Page Directives

The Page Directives are used to control certain features of page,this directives are called as commands.The compiler executes this directives.These directives can be place at the top.

Example:

<%@ %>

Some Page Directives are:

@page : This is used for to declare many page-related attributes about a particular page.This directive commonly used in asp.net.

Example:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

@import : It is used for to import different types of namespaces in the page.

Example:

<%@Import Namespace="System.Data.SqlClient" %>

@Master : It is similar to the @Page Directive. The only difference is that the @master directive is for Master pages.Any content page can inherit all the properties

Frequently Asked Questions-Sql server Questions & Answers

Here,we are providing a list of frequently asked questions and various programming interviews to developers. I have also shared my answers for these questions for quick revision and easy to understand.

Q) What are the different index configurations a table can have?

A) A table can have different types of index configurations: No indexes , A clustered index , A clustered index and many nonclustered indexes , A nonclustered index , Many nonclustered indexes.

Q) What is constraints?

A) constraints are used to specify rules for the data in a table. It can be specified when the table is created (inside the CREATE TABLE statement) or after the table is created (inside the ALTER TABLE statement). There are following types of constraints.

Unique, Default, Check, Primary Key, Foreign Key, Not Null.

Q) What is Normalization?

A) Database normalization is a data design and organization process applied to data structures based on rules that help building relational databases. In relational database design, the process of organizing data to minimize redundancy is called normalization. Normalization usually involves dividing a database into two or more tables and defining relationships between the tables. The objective is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then propagated through the rest of the database via the defined relationships.

About Language Integrated Query

Why we are using LINQ?

LINQ means Language Integrated Query.It is data access programming in .Net.LINQ is used to retriving the data from data bases like LINQ to XML, LINQ to SqlServer.

Namespace is : using System.Linq;

This LINQ has different types of components

Linq to Objects : It works with in memory data, that impliments IEnumerable interface

Namespace is : using System.Collections.Generic;

Example for Generate odd numbers:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{

IEnumerable<int> oddNums
= ((ParallelQuery<int>)ParallelEnumerable.Range(20, 2000))
.Where(x => x % 2 != 0)
.Select(i => i);

foreach (int n in oddNums) { Console.WriteLine(n); }
Console.ReadLine();
}

}
}

Frequently Asked Questions-JQuery Questions & Answers

Here,we are providing a list of frequently asked questions and various programming interviews to developers. I have also shared my answers for these questions for quick revision and easy to understand.

Q) What is jQuery ?

A) jQuery is fast, lightweight and feature-rich client side JavaScript Library/Framework. It is used for to create different types of animations, Ajax interaction, manipulate the page content, change the style and provide User Interface effects. It is one of the most popular client side library.

Q) What is the difference between JavaScript , Ajax and JQuery?

A) Javascript is a scripting language . It is dynamic.JavaScript is prototype-based.JavaScript code are all in text.JavaScript resides inside HTML documents, and can provide levels of interactivity to web pages that are not achievable with simple HTML.

AJAX is a technique to communicate between the browser and the server within a page. You can manage this interaction with Javascript on the client side, using an XMLHTTP Object provided by the browser. Ajax is a method to dynamically update parts of the UI without having to reload the page.

jQuery is a library which is used for to simplifyclient side web development . It creates a layer of abstracion so you can reuse common languages like CSS and HTML in Javascript. It also includes functions which can be used to communicate with servers very easily (AJAX).

Frequently Asked Questions-WCF Questions & Answers

Here,we are providing a list of frequently asked questions and various programming interviews to developers. I have also shared my answers for these questions for quick revision and easy to understand.

Q) What is WCF?

A) Windows Communication Foundation (WCF) is an SDK for developing and deploying services on Windows. It provides a runtime environment for services.It helps in building applications to communicate with each other.

1 . ASP .NET Web services(.asmx)
2. Remoting
3. MSMQ (Microsoft Message Queue)
4. Enterprise Services 

Q) What is the difference between WCF and Web services?

A) WCF has managing distributed programming infrastructures. It offers more flexibility and portability..

WCF supports both http and tcp protocol while webservice supports only http protocol. WCF is more flexible than web service. WCF is combination of WebService, Remoting, MSMQ

Q) What is service and client in perspective of data communication?

A) A service is a unit of functionality exposed to the world. The client of a service is merely the party consuming the service

Q) What are different binding supported by WCF?

A) Basic Binding , TCP Binding , Peer Network Binding , Web Service Binding .

Introduction to ASP.Net

 ASP.NET is a programming framework built on the common language runtime that can be used on a server to build powerful Web applications. ASP.NET offers several important advantages over previous Web development models:

What is ASP.Net web form?

The ASP.NET Web Forms page framework is a scalable common language runtime programming model that can be used on the server to dynamically generate Web pages. 

Intended as a logical evolution of ASP (ASP.NET provides syntax compatibility with existing pages), the ASP.NET Web Forms framework has been specifically designed to address a number of key deficiencies in the previous model.

How to Create the Tables in Database using SqlServer

What is SqlServer?

Sql means Structured Query Language.It is interface of the Relational Database Management System[RDBMS].It is used for to store the client information in server side for providing security to user data.The data is stored in the form of tables. Table is collection rows and columns.In this servers we are using different type of commands like create,insert,update,delete,select,alter.

In SqlServer,we are providing security to database by using 2 types of authentications.

1)Windows Authentication: it doesnot Provide the security to database.Every user can use this database directily.

2) Server Authentication: By using this authentication, Only perticular user can access this database.it provides the security to data on userid and password.
