Why to shift from ASP to ASP.NET?

The era of ASP.NET programming in the IT world has made many many programmers and customers to migrate from traditional ASP programming platform to ASP.NET programming platform. These up-gradations and provoked thought processes support them to make their business operations more effective and easy. They both too work on the same web server, hence future compatibility too is not a problem.

Here are some of the standard reasons for shifting from classical ASP to ASP.NET programming:
> Integration of any 3rd party APIs and code structures becomes relatively easy using ASP.NET
> Both ASP and ASP.NET share the same web server, so compatibility is also not an issue
> ASP.NET can manage thrice the number of requests and hits as compared to classic ASP
> Lot of features are getting automatic in case of ASP.NET, and hence requires very fewer amount of efforts comparatively
> Stability and scalability of the system gets increased in case of ASP.NET technology platform

Thus, there are a plenty of advantages associated for all the ASP.NET programmers to shift them to from classic ASP to the upgraded versions.

Authentication of an ASP.NET Web application

Form authentication is the most commonly used authentication methods of all in ASP.NET programming. Depending on the Client requirement, as a programmer one might want to consider using the SSL throughout the site or at least on the login page. But overall, this approach is not so secure as it sends the User’s credentials to the server in clear context.

Lack of password policy, passing incorrect internal messages to the browser, using cookies and other insecure means to store the Users’ credentials, etc. are the possible deficiencies with decision of authentication policy in ASP.NET programming.

A web application’s authentication in ASP.NET can be further enhanced with the following:
> Password policy… enforcement of a password policy including strong passwords, password expiration, and possibly locking User accounts after some unsuccessful login attempts.
> Hashing of password… if you manage your authentication store, make sure to hash your all the passwords for the system
> Brute Force Attacks… introduction of a random delay of a few seconds on every login attempt will make the brute force attacks impractical to execute

Key Components of Web Services in ASP.NET Programming

We have already published one blog post article with an introduction of web services, somewhere around the last month for ASP.NET programming. Basically, they are the software system designed to support interoperable machine-to-machine interactions over an established network.

A web service in ASP.NET development is built with the following components – XML, SOAP, WSDL and UDDI. Their roles can be defined as:
> UDDI… Universal Description, Design, and Integration – provides a directory of services on the internet
> WSDL… Web Services Descriptional Language – here, the web services for a program are defined in terms of formats and message ordering
> SOAP… through this, the web services consumers can send/receive messages using XML
> XML & HTTP… they are built using the available open internet protocols

Data Validation guidelines for ASP.NET applications

Data validation in ASP.NET programming is all about avoiding data cleanup tasks on the backend by avoiding bad data coming in. The ASP.NET validation controls and third party validation controls help you receive the right data in the right format. ASP.NET provides some nice controls to perform validation.

A controlled and centralized web framework can offer many advantages related to security to the web applications. In ASP.NET application development, it needs to be backed up with the page-specific security measures to ensure proper data validation. Here are some guidelines on employing proper data validation:
> Avoid the database write actions against the URL parameters
> Ensure that every POST action is actually done from an internal application page
> All the possible exceptions should send only user-friendly messages to the browser
> Any webpage displaying data on the browser that cannot be guaranteed to be safe should be encoded using the server.htmlencode. This will certainly prevent any malicious cross-site scripting attacks
> All the web pages should enforce strict data validation on any piece of data
> Consider the regular expressions as a great way to constrain input in ASP.NET

Thus, these were the basic guidelines to for effective implementation of data validation for ASP.NET programmers.

Introduction to Web Services in ASP.NET

From the books of programming, a web service is a service provided and invoked with the support of internet by using different web protocols, and with a standard interface description. It can also be explained as programmable application logic. They are very simple and easy to understand concepts in the context of ASP.NET programming. As such the usage of the web services are irrespective of the programming technology platforms… they can be used as a programmed logic in any platform, object model, or programming language used to implement that service.

An ASP.NET web service is a software system designed to support all the machine-to-machine interaction over a network. They have an interface described in a machine-process able format. The other systems interact with the web services in a fashion prescribed by its description using the SOAP messages, typically conveyed using the HTTP with an XML serialization in coordination with the other web-related standards.

What is ADO.NET?

This article holds some important information and introduction to ADO.NET (ActiveX Data Objects for .NET). ADO was for the first time released in 1996 and it represented a new way of dynamically retrieving data from any database in ASP.NET programming.

ADO.NET is an object-oriented set of libraries that allows you to interact with data sources. Commonly, the data source is a database, but it could also be a text file, an Excel spreadsheet, or an XML file. But overall, it is used as a way to interact with a data base. ADO.NET is sometimes considered an evolution of ActiveX Data Objects (ADO) technology, but was changed so extensively that it can be considered an entirely new product.

Thus, ADO.NET is the .NET technology for programmers to interact with data sources. You have several Data Providers, which allow communication with different data sources, depending on the protocols they use or what the database is.

Multithreading in ASP.NET

In ASP.NET programming, there are indeed many operations which demand to run in parallel with the main code, but demand very high CPU usage. The examples include acquiring a database and waiting for the results, any heavy 3rd party software integration, etc. – hence, here the ASP.NET programmers are suffering a heavy and loaded input/output operation. Thus, the application will be dead with no response until this time consuming operation completes.

A common solution for this problem in ASP.NET programming in multithreading.

Multithreading is a technique that can be used to perform time consuming tasks in a separate additional thread other than the main application thread. The .NET framework provides you with a class library that allows you to use multithreading and asynchronous programming techniques. In multithreading technique, you can use the thread pool to conquer the new thread, or you can also create it manually. Actually, it depends on the level of control you want to have over the new thread.

Thus, by using multithreading, you can use 2 threads in parallel – the main one, and the newly created one. Both are running in parallel, and this certainly improves the performance and responsiveness of an application.

Basic FCL Namespaces in ASP.NET Programming

We had already introduced our readers to the Framework Class Library in ASP.NET via one of the article in the first week of January. The .NET framework class library is a library of classes, interfaces, and value types that provide access to functionality of the system. All the types in the Framework Class Library are Common Language Specification (CLS) compliant.

The .NET framework contains a lot of namespaces, and each class is arranged in a namespace that best describes its purpose. All the basic FCL classes are located in the root namespace System. The classes, which are provided by any 3rd party developers are recommended to follow the standard NameSpace format of CompanyName.TechnologyName.

Structure of a Namespace:
A basic fully qualified classname example would be System.Collections.ArrayList. The part to the left of the last dot is generally the namespace, while the part to the right of the last for is the classname.

The FCL is based on the common type system. The common type system allows the framework to operate with the multiple languages within a managed runtime.

Common Language Specification: ASP.NET Programming Concept

The CLS rules basically define a subset of the Common Type System. The Common Language Specification is the basic set of rules to which any language which is targeting the Common Language Infrastructure (CLI) should confirm in order to interoperate with other CLS-compliant languages. It has been defined as a set of basic language features needed by many applications, which the ASP.NET developers need to develop the applications and services.

When it comes to communication between different objects in .NET languages, those objects must expose all the features that are common to all the languages. The CLS ensures complete interoperability among applications, regardless of the language used to create the application.

It defines a set of Common Type System (CTS) – which in turn describes a set of types that can use different languages for interaction. The Common Language Specification is standardized by ECMA too.

Garbage Collection in .NET

The garbage collection is an inline program running in background to Windows applications. It is basically a mechanism to release the unreferenced objects from the memory. The ASP.NET developers no longer need to worry about the need to manage the life-cycle of the objects they create – the garbage collector will take care of them once the application has finished with them.

When a program creates an Object, the Object takes up the some chunk of the available memory. Later, when the program has no more references to that Object, the Objects’ memory becomes unreachable, but not freed as such. The Garbage collection inspects to see if there are any Objects that are no longer being used by the application. If such objects exist, then the memory used by these Objects can be reclaimed. So, these unreferenced Objects should be removed from memory, and then the other new Objects the developers create can find a place in the program.

In ASP.NET language, there is a provision that we can call Garbage Collector explicitly in the program by calling System.GC.Collect.

Database Web Application Development in ASP.NET

Oracle or MS-SQL serve as some effective backend to build database applications in ASP.NET. In this article, we will talk about Oracle in general. Oracle integrates directly with Microsoft ASP.NET in a number of ways:

>  Enabling ASP.NET data access by using ODP.NET

>  Using Oracle developer tools for Visual Studio tools

>  Direct integration with Microsoft ASP.NET controls and services

The databases have always been the core part of the dynamic websites for ASP.NET developers.  From the above 3, I guess the 2^nd one is the easy way comparatively to make the database and the frontend of the website interact with each other.

Initially, the ASP.NET developers should use the available tools to build a web application that retrieves the data from the Oracle database into a data grid. After that, a general login control can be added in order to secure the application by permitting only the authorized web users to access the application and the information. Finally, the developers can create any number of authorized web users using Oracle providers for ASP.NET. And all the information for these created web users will be stored within the Oracle database for checking their authenticity.

At SPEC INDIA, our trained team of ASP.NET professionals are able to make any application or the most complex dynamic websites as per the customized requirements of our Clients. You can always send an email of your requirements at our email contact lead@spec-india.com and we will definitely get back to you on the same with quality results.
