Using ASP.NET To Send Email

October 18, 2017

Email is a standout amongst the most well-known and dependable strategies for correspondence for both individual and business purposes. It likewise assumes an essential part in every last Web website. This part will be in the sort of computerized messages from the server in the wake of posting data from a shape. You may have seen these sorts of messages while enrolling on a site. When you post the shape, the server will send an email requesting that you affirm either your enlistment or with the data you entered. On the off chance that you need to affirm the enrollment, the server will send you a long URL that you need to snap to continue encourage with the enlistment procedure. A great case of this usefulness is ASP.NET discussions. When you enlist, you will be messaged an irregular secret key. You will likewise get messages after your post has been acknowledged by an arbitrator or on the off chance that some individual answers to your post. On the off chance that you are pondering this is a server enchantment—it isn’t. The entire procedure is influenced conceivable with the assistance of server-to side programming structure, for example, ASP and ASP.NET.

To send messages, you ought to expect access to a server with .NET Framework and SMTP empowered on it. SMTP remains for Simple Mail Transfer Protocol and messages are sent utilizing this convention.

The .NET Framework supplies a SMTP class that empowers you to send a straightforward email message. In the event that you need to send an email with included functionalities, you need to make utilization of the MailMessage class. With the assistance of this class, you can include connections, set needs, and substantially more, effortlessly. You can likewise send HTML email utilizing this class.

Luckily, ASP.NET makes sending email a breeze. The .NET Framework adaptation 1.x incorporated various classes in the System.Web.Mail namespace that permitted automatically sending an email with a couple of sparse lines of code. While this namespace and these classes still exist in the .NET Framework rendition 2.0, they have been deplored for new mail-related classes found in the System.Net.Mail namespace.

In order to send an email from an ASP.NET Web page, we need to use the SmtpMail class found in the System.Web.Mail namespace, which contains a static method Send(). OR In order to send an email from an ASP.NET Web page, we need to use the SmtpClient class found in the System.Net.Mail namespace, which contains a method Send(). SmtpMail Class Provides properties and methods for sending messages using the Collaboration Data Objects for Windows 2000 (CDOSYS) message component. Recommended alternative: System.Net.Mail.
SmtpClient Class allows applications to send e-mail by using the Simple Mail Transfer Protocol (SMTP).

Advantages of Using ASP.NET To Send Email

There are several advantages to using ASP.NET to send email:

Easy to use: ASP.NET provides a simple and straightforward way to send email, using the System.Net.Mail namespace. Developers can easily create and send email messages, including HTML emails with attachments.
Reliable: ASP.NET uses the Simple Mail Transfer Protocol (SMTP) to send email, which is the standard protocol used by email servers around the world. This makes ASP.NET emails more likely to be delivered successfully.
Secure: ASP.NET provides a number of security features to help protect email messages from being intercepted or tampered with. For example, ASP.NET can encrypt email messages and use SSL/TLS to secure communication with the SMTP server.
Scalable: ASP.NET can be used to send email to large numbers of recipients without performance problems. This makes it a good choice for sending email newsletters and other marketing campaigns.

application state in asp.net

what is application state in asp.net

Application state in asp.net is a server side state management technique.

The date stored in application state is common for all users of that particular ASP.NET application and can be accessed anywhere in the application.

It is also called application level state management. ASP.NET provides application state via the HttpApplicationState class as a method of storing global application-specific information that is visible to the entire application.

Application-state variables are, in effect, global variables for an ASP.NET application.

We can store our application-specific values in application state, which is then managed by the server.

Data that is shared by multiple sessions and does not change often is the ideal type of data to insert into application-state variables.

Application state is a data repository available to all classes in an ASP.NET application. Application state is stored in memory on the server and is faster than storing and retrieving information in a database. Unlike session state, which is specific to a single user session, application state applies to all users and sessions. Therefore, application state is a useful place to store small amounts of often-used data that does not change from one user to another.

Application State is used to store information which is shared among users of the ASP.Net web application. Application state is stored in the memory of the windows process which is processing user requests on the web server. Application state is useful in storing a small amount of often-used data. If application state is used for such data instead of frequent trips to the database, then it increases the response time/performance of the web application.

If the information that you want to be accessed or stored globally throughout the application, even if multiple users access the site or application at the same time, then you can use an Application Object for such purposes.

“A global storage mechanism that is accessible from all pages in the Web application. Application state is stored in the Application key/value dictionary. This information will also be available to all the users of the website.”

Table of Contents

Advantages of using application state in asp.net :-

Simple implementation: Application state is easy to use, familiar to ASP developers, and consistent with other .NET Framework classes.

Application scope: Because application state is accessible to all pages in an application, storing information in application state can mean keeping only a single copy of the information (for instance, as opposed to keeping copies of information in session state or in individual pages).

Disadvantages of using application state in asp.net :-

Application scope: The scope of application state can also be a disadvantage. Variables stored in application state are global only to the particular process the application is running in, and each application process can have different values. Therefore, you cannot rely on application state to store unique values or update global counters in Web-garden and Web-farm server configurations.

Limited durability of data: Because global data that is stored in application state is volatile, it will be lost if the Web server process containing it is destroyed, such as from a server crash, upgrade, or shutdown.

Resource requirements: Application state requires server memory, which can affect the performance of the server as well as the scalability of the application.

Variables in PHP

May 30, 2017

Variable is name of memory location used to store some data.

In PHP no need to provide data types at the time of variable declaration because PHP is loosely types language .

Variable names start with ‘$’ symbol.

types of variable in PHP

Table of Contents

Local variable :-

Variable declaration within the function comes under local variable .

Local variable of a function cannot be accessed from another function.

Global variable :-

Variable declaration outside of all function come under global variable.

Global variable can be accessed from any function within the script.

Note:- We can not access global variables directry from function by using ‘$’ GLOBALS keyword. We can access global variable by using ‘$ GLOBALS’ key from functions.

Variable variables :-

If we assign a variable name as the value of another variable comes under variable variables ,

Static variables :-

Static variable can remember previous value . we can assign value only one time into static variable.

Reference variable :-

It is an alias name of a variable . both refers the value of same address locations.

Super Global variable :

PHP support no of super global variable . these variable we can access from any web page in application. All super global variables are array data types available

Scalar data types in php

May 10, 2017

In php four data types

Boolean
Integer
Float
String

Boolean data type in php

This data type can represent either true or false . In PHP value is 1 and value of false doesn’t any value.
is_bool : Using this function , we can check input variable is boolean or not.
(bool) var OR (boolean) var using this function , we convert variable into boolean variable.

Integer data type in php

This data type can store numeric value
is_int OR is_integer it is used to cheak input variable is integer or not .
(int)var ))OR (integer) var OR intval(var) Using this function , we convert variable into integer variable.

Float data type in photo

this data type can store decimal values .

is_float () this function cheacks input variuable is float or not.
(float)var Converts a variable into floating point number.

String data type in php

It is a collection of character.
In PHP , we can declar string in three ways.

By using single quotations
By using double quotations
By using heredoc syntax

NOTE Variable in double quotations returns value of variables.

Heredoc PHP suports heredoc syntax to avoid the conflicts what we getting with single and double quotations.

Compound data types
