Difference between Abstract Class and Interface ?
Dev Palmistry 
Abstract Class:
# IS-A relationship.
# e.g. Student IS A Person, Employee IS A Person.
# cannot be instantiated.
# normally used for framework-type library classes: providing default behavior for some of its class members, but forcing the developer to implement
others.
# It has to be inherited for use .
# You need to INHERIT to use an abstract class.
# Attempting to instantiate an object of an abstract class retults in a compilation error
# Any Class with abstract method or property in it must be declared abstract
# Abstract will allow you to set the access specifier. Ex:- (private,public, protected, internal).
# Abstract will allow you to implement the body in abstract methods.
# Situation where functionality may add/remove "Abstract Class" is best solution.
# Eg. Creating Base Classes,Creating Base for your project where functionality may be added or remove or can be override if needed.Mostly common task are
move to base class and if required than can be overrided.
# in Abstract class you can Declare the Constructors,fields,methods,indexes,destructors etc
# practical example for abstract class:
we can use account class in bank as abstract class.inreality
there will be no account we can use .but only sbaccount and current account will be exist.so we can use account class as abstract
class and we can inherits this class in sbaccount class,current account class
# Example:
pulic Abstract Class A
{
public void Hi();
public void Hello()
{
Console.WriteLine("hello method");
}
}
public Class B
{
public overid void Hi()
{
Console.WriteLine("hi method");
}
2. Abstract Class: Allows common functionality to be shared across similar objects
Of course, don't use an abstract class in cases where functionality doesn't need to be shared.
Interface:
# CAN-DO relationship.
# e.g. Student CAN enrol, Student CAN submit assignment.
# cannot be instantiated.
# group of related methods with empty bodies .
# You need to IMPLEMENT to use an interface.
# The implementation of an interface is left completely to the developer.
# Interfaces can contain only the signature of a method but no body.
# Interfaces are used to declaring functionality.
# By default all interface methods are public.
# Situation where we have fix requirement "Interface" is best solution.
# Eg. Plugin .Where Pluging can be loaded dynamically and executes its functionality.
Thus that Plugin must follow or implement certain functionality.
# In class you can implement the interface method, but can’t implement the body in Interface method.
# in interface you can not Declare the Constructors,fields,methods,indexes,destructors
# Examples:'
//mutltiple inhiritance
Interface IA
{
void cat();
void Dog();
}
Interface IB
{
void door();
void tyres();
}
public class C:IA,IB
{
public void cat()
{
Console.WriteLine("hello cat method");
}
public void dog()
{
Console.WriteLine("hello dog method");
}
public void door()
{
Console.WriteLine("hello door method");
}
public void tyres()
{
Console.WriteLine("hello tyres method");
}
}
Exp : 1. Interfaces are useful when you do not want classes to inherit from unrelated classes just to get the required functionality. For example, let bird
be a class with a method fly(). It will be ridiculous for an aeroplane to inherit from bird class just because it has the fly() method. Rather the fly()
method should be defined as an interface and both bird and aeroplane should implement that interface.
Exp 2. Hi what suits my case !! Say a real estate builder is constructing an apartment with many flats.All the rooms in the flats have the same design,except
the bedroom. The bedroom design is left for the ppl who would own the flats i.e; the bedRooms can be of different designs for different flats.
I can achieve this through an abstract class like below:
public abstract class Flat
{
//some properties
public void livingRoom(){
//some code
}
public void kitchen(){
//some code
}
public abstract void bedRoom();
}
An implementation class would be as follows:
public class Flat101 extends Flat
{
public void bedRoom() {
System.out.println("This flat has a customized bedroom");
}
}
# Interface is without implementation, just interface or virtual methods.
# As per my understanding, it is can-do or is-do relationship. Like, from .NET framework, there are many interface like IComparer, ISortable etc. So, it is
something like, classes derived from the interface CAN-DO these things.
Defference :
# A class can inherit one or more interfaces, but only one abstract class.
# An abstract class can have abstract members as well non abstract members. But in an interface all the members are implicitly abstract and all the members
of the interface must override to its derived class.
# The members of the interface are public with no implementation. Abstract classes can have protected parts, static methods, etc.
# Interface are similar to abstraction classes.However , interfaces represent the higest level of abstraction in Object- oriented programming.This is because
all the methods in an interface are abstract and do not have implementation.In contrast ,the abstract classes might contain a method that has a body.
# 1).Interface have only signature. whereas Abstract class have signature and definition both r allow. 2). Interface have not allow modifier access. whereas
Abstract class are allowed modifier access. 3).Thurogh the Interface we can create the Multiple Inheritance whereas Abstract class are not allow the Multiple
Inheritance. 4).Interface is slower compare Abstract class.
# An abstract class may contain complete or incomplete methods. Interfaces can contain only the signature of a method but no body. Thus an abstract class can
implement methods but an interface can not implement methods. · An abstract class can contain fields, constructors, or destructors and implement properties.
An interface can not contain fields, constructors, or destructors and it has only the property's signature but no implementation. · An abstract class cannot
support multiple inheritance, but an interface can support multiple inheritance. Thus a class may inherit several interfaces but only one abstract class. · A
class implementing an interface has to implement all the methods of the interface, but the same is not required in the case of an abstract Class. · Various
access modifiers such as abstract, protected, internal, public, virtual, etc. are useful in abstract Classes but not in interfaces.
# Interface:- 1. Interfaces are used to declaring functionality. 2. By default all interface methods are public. 3. In class you can implement the interface
method, but can’t implement the body in Interface method. Abstract:- 1. Abstract will allow you to set the access specifier. Ex:- (private,public, protected,
internal). 2. Abstract will allow you to implement the body in abstract methods. 3. You can inherit the abstract methods in classes
# • Abstract Class
Cannot be instantiated.
Must be inherited and its methods should be overridden.
It have some concreate methods.
Access modifiers allowed.
• Interface
Have definition of a method not implementation. (implement through class)
Multiple inheritance possible through Interface only
Only Public Access modifier only allowed. Defaultly Public
No need of virtual overridden.
It’s used for to define a set of properties, methods and events.
# Following are the difference between abstract and interface,
1>Abstract class having method declaration as well as method method definition whereas interface having method declaration only.
2>Abstract class are known as partial abstract class whereas interface is known as fully abstract class.
3>Abstract class features we have to inherit to the child class whereas interface features we have to implement in the child classes.
4>Abstract class support access specifiers whereas interface doesn't support access specifiers.
5>Abstract class have normal variable as well as constant variable whereas interface have only constant variables.(Discuss it)
6>We can write constructor in abstract class whereas we can't write constructor in interface.
# Interfaces are similar to abstract classes.However,interface represent the highest level of abstraction in object-oriented programming.This is because all
the methods in an interface are abstract and do not have implementation.In contrast,the abstract classes that are created using Abstract keyword might
contain a method that has a body.
# Abstract Class vs. Interface
· An abstract class may contain complete or incomplete methods. Interfaces can contain only the signature of a method but no body. Thus an abstract
class can implement methods but an interface can not implement methods.

Difference between Trace and Debug Class !
Dev Palmistry
Trace and Debug classes :
Fortunately, you do not have to step through an application line by line to figure out what is happening.
The Systems.Diagnostics namespace includes Trace and Debug classes.
These two classes (which are essentially identical) include a number of static methods that can be used to cause your code to gather information about code-execution paths, code coverage, and even performance profiling. Both classes also provide an Assert method that checks for a condition and displays a message if the condition is false.
Tracing : Tracing is actually the process of collecting information about the program's execution.
Debug : Debugging is the process of finding & fixing errors in our program.
What’s the difference between the Debug class and Trace class?
Documentation looks the same. Use Debug class for debug builds, use Trace class for both debug and release builds.

Join-Cross join
A join is a query that combines rows from two or more tables, views, or materialized views.
Most join queries contain WHERE clause conditions that compare two columns, each from a different table. Such a condition is called a join condition.
CROSS JOIN (Cartesian product) is the simplest join.
We can start with the simplest possible join -- the "cross join" (or Cartesian product). If we have two database tables consisting of information about CDs and musical artists:
A join simply multiplies the two tables together into a new virtual table. There are four members of the Artists table and seven members in the CDs table which will result in 28 (!) rows in the result. You can try this using the following syntax,
SELECT * FROM Artists, CDs
and you should see a result that looks like the following table:
This table is typically filtered using the WHERE clause, for example
SELECT * FROM Artists, CDs WHERE Artists.ArtistID=CDs.ArtistID

The out put will come like DENESH KUMAR, VIJAY SHUKLA
Que . How to get the image on the user page by DataReader ?
Ans : TitleImage.Imageurl=folderpath + dirv["au_page_image"].ToString() ;
Note : 1 . For getting the folderpath we use this code on .cs page public string folderpath =
ConfigurationManager.AppSettings["folserpath"].ToString () ;
2. This key is defined in the Web.Config file like that -
<>
< key="folderpath" value="upload/">
3. Upload is the folder where the image is stored .
4. ImageUrl is like txt for text box of Image .Like txtname.text .
Que : How to show the Image on the User Page by GridView ?
Ans : By This Code
'/> Note : 1. In The Upload folder , image is stored there .Image has two things one Image and
second its name (boy.jpg)
2. Image Name like (boy.jpg) is saved in database's field like (dir_image) .
Mistake : One mistake when i was using DataReader .
Ans : 1. In the DataReader while loop are used . i don't know foreach loop can be used or
not , but when i was using it was not working .I was using foreach loop in DataReader and it

Que : What is the ID of ASP.NET server controls ? And why it is used ?
Ans : By ID property of the server control, we can uniquely identify the control.We can not have the two server contros on the same wev forms with same ID. The ID of server control is used as a reference in the c# source code behind file .cs file.
For your control's ID name use some meaning full nameing covention so that your code become more readable and easier to understand.It is very difficult to debug and maintain a program where the control names are TextBox1, Button1, and so forth.
So there are some prefixes appended with meaningful name for server control.
txt = TextBox (e.g. txtLastname)btn = Button (e.g. btnSavedata)ddl = DropDownList (e.g. ddlAccounts)chk = CheckBox (e.g. chkAdmin)rb = RadioButton (e.g. rbSpringsemester)

txt = TextBox (e.g. txtLastname)btn = Button (e.g. btnSavedata)ddl = DropDownList (e.g. ddlAccounts)chk = CheckBox (e.g. chkAdmin)rb = RadioButton (e.g. rbSpringsemester)
Event Handler Method !!
Que : What is Event Handler Method ?
Ans : An event handler method is a special type of Method in an ASP.NET web page that defines the actions that will occur when a particular event occurs.
Example : Take an examle of event handler method, first take an event : click event. We saw that if you are int the Design view for a wev form and you double click on a Buttion control, Visual Web Developer or Visual Studio will automatically generate an event handler Method called Buttion_Click.Basically an empty method is generated and Visual Web Developer or Visual Studio lets you put what ever code you want into that event handler.
Que : What is the meaning the event driven model ?
Ans : ASP.NET uses an event driven programming model.This means that in order for code to run, an event must occur that triggers or tells ASP.NET to run an event handler Method.
Que : What is the naming convention of Event Handler Method ?
Ans : Notice the naming convention that Visual Web Developer when it generates the event handler Method. The first part of the name is the ID for the server control: Button1. The second part of the name an underscore appended with the event type: Click. This convention helps you as the developer know when that Method will be called by ASP.NET. In this case, the click event fires when a user single clicks on the Button control.
