Sending email through System.Net.Mail.Smtpmail in asp.net 3.5/2.0

For any web application or website the sending email is a necessity for newsletter, invitation or reset password for everything we have to sent a mail to the people. So we need to see how we can send mail. In 1.1 we are sending emails with System.Web.Mail.SmtpMail which is now obsolete. Now in asp.net 2.0 or higher version there is a namespace called System.Net.Mail.Smtpmail in asp.net 3.5. With this namespace we can easily write a code to send mail within couple of minutes.

If you want to sent a mail first thing you need is smtpserver. Smtpserver is a server which will route and send mail to particular system. To use smtpserver we need to configure some settings in web.config following is the setting for the web.config.

<system.net>

    <mailsettings>

       <smtp deliveryMethod="Network">

         <network host="stmp server address or ip"

           port="Smtp port" defaultCredentials="true"/>

        </smtp>     

    </mailsettings>

</system.net>

Here you need to set the all the smtp configuration. This will be used by the smptclient by default. Here is the code for sending email in asp.net 3.5

SmtpClient smtpClient = new SmtpClient();

MailMessage message = new MailMessage();

try

{

   MailAddress fromAddress = new MailAddress("from@site.com","Nameofsendingperson");

   message.From = fromAddress;//here you can set address

   message.To.Add("to@site.com");//here you can add multiple to

   message.Subject = "Feedback";//subject of email

   message.CC.Add("cc@site.com");//ccing the same email to other email address

   message.Bcc.Add(new MailAddress("bcc@site.com"));//here you can add bcc address

   message.IsBodyHtml = false;//To determine email body is html or not

   message.Body =@"Plain or HTML Text";

   smtpClient.Send(message);

}

catch (Exception ex)

{

   //throw exception here you can write code to handle exception here

}

So from above simple code you can add send email to anybody
Adding Attachment to the email:If you want to attach some thing in the code then you need to write following code.

message.Attachments.Add(New System.Net.Mail.Attachment(Filename));

Here file name will the physical path along with the file name. You can attach multiple files with the mail.

Sending email with Authentication: If you want to sent a email with authentication then you have to write following code.

System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient();

     //This object stores the authentication values

     System.Net.NetworkCredential basicCrenntial = 
          new System.Net.NetworkCredential("username", "password");

     mailClient.Host = "Host";

     mailClient.UseDefaultCredentials = false;

     mailClient.Credentials = basicCrenntial;

     mailClient.Send(message);

Happy Coding…

What’s new in asp.net 4.0 and .net Framework 4.0?

Microsoft.NET Framework 4.0 beta version is out now. Let’s see the what’s new in asp.net 4.0 for the developer purpose. There are lots of features are there. Some of them are following.

1) Extensible Output Caching:

ASP.NET 4.0 adds an extensibility to output caching now you can create your cache provider and will can use this provider for the caching. So now you can use your own data source for you caching.

2) AutoStart Webapplication

Before asp.net 4.0 you have to use application_load or application_start event for the extensive data processing before application pages loads. But now you can use auto start features of asp.net 4.0. A new scalability feature named auto-start that directly addresses this scenario is available when ASP.NET 4.0 runs on IIS 7.5 on Windows Server 2008 R2. The auto-start feature provides a controlled approach for starting up an application pool, initializing an ASP.NET application, and then accepting HTTP requests.

3) Permanently Redirecting a page

Before asp.net 4.0 you need to use response.redirect method to go to another page from new page. ASP.NET, developers have traditionally handled requests to old URLs by using by using the Response.Redirect method to forward a request to the new URL. However, the Redirect method issues an HTTP 302 Found (temporary redirect) response, which results in an extra HTTP round trip when users attempt to access the old URLs. Now permanent redirect will solve this. Its will also benefit for the Search Engine Optimization.

4) Compressed Session State:

ASP.NET 4.0 will have new option for session stored in sql server or in state service. You can compress your serialized session using GZip Compression

5) Page.Keywords and Page.Description Properties

In asp.net 4.0 now you can create dynamic keywords and description for a page using Page.Keywords and Page.Description Properties

6) Enabling View state for Individual Controls

In earlier version of the asp.net if you disable your parent control view state it will disable your child control view state but now with asp.net view state is not dependent on parent child control view state.

7) Routing in asp.net 4.0

Now you can have build in routing for your pages. You don’t have to write your url rewriting modules. It introduces a WebFormRouteHandler routing class which will take care of routing.

8) ClientID

In earlier asp.net version clientId is system generated and if you want to change you have to override it . ASP.NET by default generated a big string for the clientid which will increase your html kb. With asp.net you have small client id using different options Legacy,Static,Predictable,Inherit

There are several other features are also there like following

Live Data Binding

Observer pattern using JavaScript and JavaScript objects

ADONetServiceProxy Class

Formview Control Ehancements

Ajax Improvements in asp.net 4.0

I have just list some of the features you can have all the features available in asp.net 4.0 white paper from the following link.

DataSet Vs Datareader

Before some time a reader  vamsi asked me in my increase asp.net application performance post that why should i prefer data reader over dataset. Both data reader and dataset are usually use to fetch data from the database but both are having different mechanism for fetching data from database. First we looked into that and then we decide in which condition we need to use dataset and in which condition we need to use data reader.

DataReader:

Datareader fetch data one by one from the database. You can have one row(record)  at a time in datareader. Once you read next row with read method of the datareader the older record is destroyed from memory and new record will take place instead of it. You can do that only forward only and you can not modify the data. It also require a database connection to stayed open while fetching data. You can use CommandBehavior.CloseConnection property to close connection after data reader finish reading data from database.

Dataset:

You can call dataset a mini database in your memory. Dataset support disconnected architecture as once you fill dataset with data then no connection is required. A database can contain multiple tables also its supports relationship between them. You can insert,update and delete records from dataset and you can update them also in database.

Where i should use dataset over database?

When you are required to display only data then use datareader.Dataset will fetch data once a time. So if you are having millions of records then it will consume your server memory while datareader will have just one record at a time in database. And you need not to display millions of records at time.

Following are the link from which you can find which is best suited for your need.

What is the difference between User Control and Custom Control

Custom controls are compiled code(Dlls) easier to use,difficult to create and can be place in toolbox. You can drag and drop controls, Attributes of this control are visually set at design time. A custom control can be used in multiple application as shared DLLS. Any one can copy DLL of custom control in bin directory and add reference and use them. Normally custom controls are designed to provide custom functionality independent of consuming application.

User controls are similar to those of asp include files easy to create, can not be placed into the toolbox and dragged dropped from it. A User controls can share single application files. Normally designed to provided functionality that is reusable for the particular application.

JavaScript Events

Following are some of the events that are provided by JavaScript

OnChange:

Occurs when user changes values in an input control. In text controls this event fire after user changes focus to other controls

OnClick:

This event occurs when a user clicks on the button control.This event is also occurs when a form is submitted to server.

OnMouseOver:

This events occur when user moves the mouse pointer over a control.

OnMouseOut:

Occurs when the user move mouse pointer over a control.

OnKeyUp:

Occurs when user release a pressed key.

OnSelect:

Occurs when the User selects a portion of a text in a user control.

OnFocus:

Occurs when a control receive focus.

OnBlur:

Occurs when a focus leaves controls.

OnAbort:

Occurs when user cancels image download.

OnError:

Occurs when an image can’t be downloaded

Onload:

Occurs when a new page finishes downloading.

OnUnLoad:

Occurs when a page is unloaded(This typically occurs when a new url has been entered_

Authentication and authorization in asp.net

Authentication is the process that determines the identity of a user after a user has been authenticated, a developer can determine if the identified use has authorization to proceed.

Authorization is the process of determining whether an authenticated user is permitted access to other any part of application or access to specific data view that application provides.

There are three types of authentication method is provided by the asp.net users.

1. Windows Authentication –Basic, Digest .
2. Forms Authentication.
3. Passport and integrated authentication.

Windows Authentication:

Windows authentication is used together with IIS authentication. When IIs Authentication is complete,ASP.NET uses the authenticated identity to authorize access. This is default settings.

Forms Authentication:

In forms authentication request that are no authenticated are redirect to an html form using HTTP client side redirection. The user provides his login information and submits the form. If application the request, the system issues a form that contains credentials or a key or a identity

Passport Authentication:

It is a centralized authentication service provided by Microsoft that offers single login and core profile services for member sites. This mode of authentication was de-emphasized by Microsoft at the end of 2004 year.

How to set authentication in web.config:

You can set the authentication mode in web.config as follows.

<Authentication Mode=”WindowsFormsPassportNone”></Authentication>

Increase Performance in asp.net application

For every enterprise level application the key to make that application success is the responsiveness of application. ASP.NET also offers great deal of the features for developing web based enterprise application but some times due to avoiding best practice to write application the performance of application performance of application is not so fast as it should be. Here are the some use full suggestion to make your application super fast.

1. Always set debug=”false” in web.config production environment.
2. Always set trace=”false” in web.config production environment
3. If you are using asp.net 2.0 or higher version then always use precompiled version of your code and also prefer web application project over website. If you are using website then always publish it and then upload that precompiled version of your site in production environment.
4. Always compile your project in Release Mode before uploading application to production environment.
5. Decrease your html kb as much as you can for that use tables less html using div’s and if possible then do not give big name to your control it will increase your html kb as asp.net uses client Id to differentiate all the controls. If you are creating custom controls then you can overwrite your clientid and uniqueId.
6. Use cache api as much as possible it will decrease your server roundtrip and boost application performance. ASP.NET 2.0 or higher version provides functionality called sqlcachedependancy for your database caching. It will validate cache with your database operation like insert,update and delete and if not possible with it then use the file base caching.
7. Remove blank spaces from your html it will increase your kb. You can use regular expression to remove white spaces. I will post the code for removing white spaces next posts.
8. For asp.net 2.0 and higher version use master pages. It will increase your performance.
9. Prefer database reader over dataset unless and until you have specific reason to use database.
10. Use ADO.NET asynchronous calls for ado.net methods. asp.net 2.0 or higher version is supporting your performance. If you are using same procedure or command multiple time then use ADO.NET Prepare command it will increase your performance.
11. Do IIS performance tuning as per your requirement.
12. Disable view state for your controls if possible. If you are using asp.net 2.0 or higher version then use asp.net control state instead of view state. Store view state in session or database by overriding the default methods for storing view state.
13. User Server.Transfer instead of response.redirect.
14. Always use inproc session state if possible.
15. Use Ajax for your application wisely. Lots of Ajax calls for a page will also decrease your performance.
16. Measure your application performance with tools like redgate profiler,firebug and whyslovw from yahoo.
17. User System.Text.StringBuilder for string concatenation its 4 times more faster then the normal strings.
18. Right JavaScript in .Js files and place it as bottom of the application.
19. Use Separate CSS files for styling of application.
20. User database paging over normal paging while displaying huge amount of data.
21. Call web service from java script instead of server side. Use asynchronous calls to call a web method from web service.

That’s it!!…..Happy Programming..

Implementing repository pattern with the ado.net entity model

There are lots of ways to implement repository pattern but with ado.net entity model you can create repository pattern within 10 to 15 minutes.

If you are creating asp.net mvc application then just right click->Model folder->Add->Net Item->select ado.net entity data model.



From database explorer right click and drag your tables to your database explorer. It will create a entity class. For example i have created a notes table for my sample and it will create a notes entity class in my ado.net entity data model.



After creating the entity class not its time to create a interface for repository pattern which will contain my all the operations related to notes entity.

Following is the interface which we will implement use for repository.

namespace DotNetJapsMVC.Models.Respository.Interface
{
interface INotesRepository
{
void CreateNotes(Notes notesToCreate);
void EditNotes(Notes notesToEdit);
void DeleteNotes(Notes notesToDelete);
Notes GetNotes(Guid noteId);
IEnumerable ListNotes();
}
}

Now we will create a class that will implement this repository interface. Here is the coding for that.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotNetJapsMVC.Models.Respository.Class
{
public class NotesRepository:Interface.INotesRepository
{
private DotNetJapsEntities _myEntities = new DotNetJapsEntities();

public void CreateNotes(Notes notesToCreate)
{
_myEntities.AddToNotes(notesToCreate);
_myEntities.SaveChanges();
}

public void EditNotes(Notes notesToEdit)
{
var originalNotes = (from n in _myEntities.Notes
where n.NoteId == notesToEdit.NoteId
select n).FirstOrDefault();

_myEntities.ApplyPropertyChanges(originalNotes.EntityKey.EntitySetName, notesToEdit);
_myEntities.SaveChanges();

}

public void DeleteNotes(Notes notesToDelete)
{
var originalNotes = GetNotes(notesToDelete.NoteId);
_myEntities.DeleteObject(originalNotes );
_myEntities.SaveChanges();
}

public Notes GetNotes(Guid noteId)
{
return (from n in _myEntities.Notes
where n.NoteId == noteId
select n ).FirstOrDefault();
}

public IEnumerable ListNotes()
{
return _myEntities.Notes.ToList();
}

}
}

That's it we have created the repository classes and repository interface. You can use as following in your class or pages.

private  INotesRepository _repository;

public List LoadNotes()
{
 return _repository.ListNotes();
}

Advantage Of Repository Pattern:

1. Make application loosely coupled so if you want to change the something then you don't need to change everything from scratch.
2. With the repository pattern we can have nice abstraction which will separate our business logic as well as database logic.
3. You can prevent dependency injection through the repository pattern.

Which .NET Object Relational Mapper is fastest? In .NET Nhibernate,Linq 2 SQL,Entity Framework Or SubSonic, NHibernate

There are lots of ORM(Object Relational Mapper) tools are available for the Microsoft.NET like linq 2 sql, ado.net entity framework, nhibernate, subsonic and so many others. Developer often confuses which technlogy he should choose but i think a developer should deternmine his requiremnt first then he has check the pros and cons of every tool there .

I have used ado.net entity framework for my application as i like it most and its easy to use.

Member of class - Object Oriented Programming

Definitions Of Object: An object is combination and collection of data and code designed to emulate a physical abstract enmity.You can create number object of class. The properties, Variable and Methods define in class are called Members of class.

1. Private Member Of Class: Private member of a class have strict access control Only the member function of same class can access this members.
2. Protected Member of Class: A Protected member is accessible to member of its own calls and to any of the class member in a derived class.
3. Public Member Of Class: A public member of class can be accessible from any where.
4. Public and Private Static Member Of a Class: The static member of a class can be access without creating a object of class. While to access other member of class you have to create a object of class. The public static member can be accessed using access specifier while private static member can be accessed only the member functions.

Inheritance and Member Accessibility:

1. A private member is accessible only to members of the class in which private member is declared. They cannot be inherited
2. A private member of the base class can be accessed in the derived class through the member of the base class.
3. A protected member is accessible by member of its own class and to any of the class member in a derived class.

Diffrent Type Of Inheritance- Object Oriented Programing

Following are different type of inheritance..
1) Single Inheritance:
Derivation of class from only one base class is called single inheritance.
2) Multiple Inheritance:
Derivation of class from several base class is called multiple inheritance.
3) Hierarchical Inheritance:
Derivation of several classes from a single class is called hierarchical inheritance.
4) Multilevel Inheritance:
Derivation of a class from another derived class is called multiple inheritance.
5) Hybrid Inheritance:
Derivation of a class involving more then one form of inheritance is called hybrid class.
6) Multi path Inheritance:
Derivation of a class from another derived classes which are derived from the same base class is called multi path inheritance.

Basic Concept Of Object Oriented Programming

Following are the basic concepts of object oriented programming.
1) Objects:

Object are the basic run time entities in the object oriented system. They may represent a person, a palace, a bank account, a table data or anything that a program can handle.

2) Classes:

A class encloses both the data and function that operate on the data into a single unit.

3) Data abstraction and Encapsulation:

The wrapping of data and function in a single unit is know as encapsulation. It is a mechanism that associate into the single unit and keeps them safe from external interference and misuse.

Abstraction refers to the act of representing essential features without including the background details or explanations.

4) Inheritance:

Inheritance is the process by which objects of one class acquire the properties of objects of another class.

5) Polymorphism:

Polymorphism means ability to take more then one form. For example as operation may execute different behaviour in different conditions. The behaviour depends on type of data used in operations.

6) Dynamic Binding:

Binding refers to the linking of a procedure call to be executed in response to the call. Dynamic binding means that the code associated with a given procedure call is not know until the time of call at run time. Virtual functions are the best examples of dynamic binding.

7) Message Communications:

An object oriented program consists of a set of objects that communicate with each other. Object

communicate with one another by sending data receiving information much same way as people passes messages to one another. A message for an object is a request for the execution of a procedure and therefore will invoke function in the receiving object that generates desire results.

8) Extensibility:

It is a feature which allows the extension of the functionality of the existing software components.

9) Delegation:

It is a alternative to the class inheritance. Delegation is a way of making object composition as powerful as inheritance. In delegation two objects are invoked in handling a request, receiving object delegates operation to its delegate. This is analogues to the child class sending a request to the parent class.

10) Generaticity:

It is a technique for defining software components that have more then one interpretation depending on the typoe of parameters.

Object Oriented Interview Question Part 1- Benefits Of Inheritance

Following are the benefits of the inheritance...

1. Through inheritance we can eliminate the redundant code and extend the user of the existing classes.
2. We can build program from the standard working modules that can communicate with the one another rather then having start writing code from beginning.
3. It is possible to have multiple instances of objects of class without any interface.
4. It is easy to partion the work.
5. Object oriented system can be easily upgraded from the small to the large systems.
6. Easily modifying and extending implementations of components without having to recode everything from scratch.

How to convert a class library project into web application? What is web application? Difference between website and web application?

Web applications are there Visual Studio.Net 2003. After launch of Visual studio.Net Microsoft has introduced a new concept like website. But after huge demands community Microsoft has reintroduced Microsoft web applications project which is very similar to webapplication in vs.net 2003. With visual studio.net 2008 you will have both the options webapplication and website to create asp.net application. First we discuss the difference between it.

 

Difference between webapplication and website.

The main difference is that website project can be complied on the fly. You need to compile every time when you changed the code. While in webapplication you have compile solutions and create binary files(.DLL) in the code then you can have new code effect in application.It will have all the code in bin folder as DLL.

Website project can be opened without a project solution file while webapplication projects can not opened without a solutions.

 

A website usually refers to the front-end interface through which the public interact with your business online.Website's are typically informational in nature with a limited amount of advanced functionality. Simple websites consist primarily of static content where the data displayed is the same for every visitor and content changes are infrequent. More advanced websites may sport features such as Commerce, content management and interactive content.

Where AS A web application or Rich Internet Application (RIA) usually includes a website component but features additional advanced functionality to replace or enhance existing business processes. The interface design objective behind a web application is to simulate the intuitive, immediate interaction a user experiences with a desktop application.

Web applications frequently integrate with existing business IT infrastructure such as accounting packages, stock management systems, ERP, etc.

 

You can download web application projects for visual studio 2005 from the following location.

Automated Testing for ASP.NET- NUnit ASP

We all developing asp.net application using Microsoft.net and as a human being we all can't kept track of each and everything. We meant to have some error in our code. We call them bugs. Bugs can be removed via testing. Some time testing take more time then expected, so we have to use the automated testing tool to test your asp.net applications.

I have found a great automated testing framework for asp.net. It is a great thing which can do the test and find bugs.

Overview

NUnitASP is a tool for automatically testing ASP.NET web pages. It's an extension to NUnit, a tool for test-driven development in .NET.

Once you have an automated suite of tests, you'll never go back. It gives you incredible confidence in your code. That confidence allows you to code much faster, because you can make risky changes secure in the knowledge that your tests will catch any mistakes.

NUnitAsp is for unit testing ASP.NET code-behind only. It's meant for programmers, not QA teams, and it's not very good for QA-style acceptance tests. It only tests server-side logic. JavaScript and other client-side code is ignored. But if you're using ASP.NET, it's an essential part of your programmers' toolset.

Here is the URL from which you can download the framework.
