Overview And Benefits Of Mobile Web Development With ASP.NET

ASP.NET mobile web development does not differ substantially from web development for desktop. ASP.NET provides a System.Web.Mobile namespace which is dedicated to mobile web development that contains core capabilities like authentication and error handling. Whether it is for desktop or mobile, development follows the basic .NET event driven model that helps the application to respond to requests and button clicks etc.

Although, the protocol for designing the web pages is same for desktop and mobile, the basic ASP.NET architecture does not support developing common pages for both the platforms. Reason being, the design and the layout might not be conducive for a mobile platform due to the limitations of the web browser, limitations of space in a mobile screen, the resolutions and lot of such features.

In addition to that, some basic functions like filling up a form might be a problem. Showing all the possible controls and validation errors might get untidy due to the lack of space. Further, the process of typing and filling up the form in itself could be an issue as it is not very convenient to type on a mobile platform.

Due to these reasons it is essential that you create different pages for your mobile. If a page is designed specially for a mobile device then it allows having better presentational formats making it more appropriate with the display area and input hardware of a mobile.

ASP.NET web application development is also supported by System.Web.Mobile namespace through which you can add mobile Web server controls once mobile web page from MobilePage base class has been made. These server controls have many specialized adaptors that are designed for developing mobile web pages and thus provide strong support and add the element of ease in the developmental process.

These adaptors can be customized for each device or the existing ones can be modified depending on the requirement. The best part is that Microsoft keeps providing updates for the adaptors whenever a new markup language evolves. This allows you to use the new languages with same controls that you have been using.

With such kind of adaptability and provisions, Mobile Web Development Services become all the more easy and beneficial. With ASP.NET evolving all the time, the development options it provides are endless.

4 Reasons Why ASP.NET is Better Than ASP Classic

Asp.net is superior to ASP Classic. There are four main areas that make ASP.NET a much better choice for programmers. These four areas include: stability, performance, scalability and language support.

#1 Stability

ASP is running under the inetinfo.exe (IIS) process space, making it susceptible to application crashes. This happens because the IIS needs to be stopped or restarted on a regular basis. The ASP.Net process is separate from inetinfo.exe, meaning that it is not susceptible to these types of application crashes. This means that the final product will be much more stable.

#2 Compilation

ASP Classic is comprised of VBScript or Jscript interpreted at run-time which means each page has a specific performance hit due to line by line interpretation. The interpretation of the pages simply results in some inefficiency.

ASP.NET however compiles the code the first time it is accessed. The compiled code results in .NET classes housed within assemblies and allow subsequent page requests to be serviced with previously compiled code. ASP.NET therefore inherently provides a more secure and largely efficient rendering model by incorporating compilation and specifically the reuse of the compiled code. This ultimately means a better experience for the end user.

#3 Scalability

With Classic ASP applications, components used by pages are fairly difficult to update, maintain or replace. In general updating a component in a running application will require the shutting down of IIS, replacement of the component and finally a restart of IIS.

ASP.NET was built to provide specific enhancements that allow scalable and efficient application updating. The 'xcopy' deployment model of .NET allows replacement of pages and components in real time and does not require a restart of the web server. If an update needs to be made to a current production application, developers can simply make the change and the infrastructure can account for that change the next time a request is made to the altered page or component. This means that content updates, fixes and enhancements to ASP.NET applications can be made in real time with little to no impact to the user base.

#4 Language Support

ASP.NET supports full server side programming languages and not just scripting languages. Only VBScript and Javascript are available for scripting in ASP Classic where as, in ASP.NET there are no such restrictions. With ASP.NET several programming languages like C# and VB.NET are available to program in accordance to the developers preference where both of them can even be used in the same application. The benefits of using server side programming languages can be seen in the previously mentioned compilation of code and the fact that rich control sets and complex frameworks are available to applications. In summary, the language support of ASP.NET allows for the development of robust, feature rich applications with deep programmatic support.

ASP.NET gives programmers much more flexibility by allowing them to provide a much better product to the end user. There are many custom programming firms that specialize in ASP.NET programming for web applications, desktop applications and even mobile type applications.

N-tier Architecture in ASP.NET

Architecture is an important feature and the very first step in the development of an application. n-Tier the term is used for multiple tier or multiple layers. n-Tier Architecture splits the solution process into different projects based on the business requirements. The main advantage of using n-Tier is that the complexity associated with the business and the process is reduced and it is easy to work with. The elements of performance, scalability and future development issues need to be considered when deciding on the architecture of the application depending on the priorities required.

The n-Tier application has three tiers or layers, they are called the presentation tier, the business tier and the data tier. Each layer interacts with the layer directly below, and has specific function to perform. Presentation Layer is responsible for displaying user interface to either programmer or end user. Programmer uses this layer for designing purpose and to get the data back and forth. In ASP.NET it includes ASPX pages, user controls, server controls and sometimes security related classes and objects.

The Business layer works as a mediator to transfer the data from presentation layer. In the three tier architecture the data access layer is not made to interact with the presentation layer. The architecture in ASP.NET includes using SqlClient or OleDb objects to retrieve, update and delete data from SQL Server or Access databases and passing the data retrieved to the presentation layer in a DataReader or DataSet object, or a custom collection object. The Data layer gets the data from the business layer and sends it to the database or vice versa. This layer is further divided into two sub layers Business Logic Layer (BLL) and Data Access Layer (DAL). DAL is responsible for accessing data and forwarding it to BLL. In ASP.NET it uses SqlClient or OleDb to retrieve the data and send it to BLL in the form of a DataSet or DataReader. BLL (Business Logic Layer) is responsible for preparing or processing the data retrieved and sends it to the presentation layer.

The Data layer gets the data from the business layer and sends it to the database or gets the data from the database and sends it to the business layer. In ASP .NET it is an SQL Server or Access database. It can also be Oracle, mySQL or even XML.

In an ASP.NET n-tiered architecture web pages do not make direct calls to the database. A given layer only communicates with its neighboring layers. ASP.NET Web pages should reference custom objects defined in the business object layer. These objects provide database information in a class structure.

The partitioning of ASP.NET applications into front-end, middle tier and back-end layers, the n-Tier architecture supports a more uniform, building block approach to application designs. Hardware and software for presentation, application and database functions can be scaled separately, and included more easily into complex e-Business environments.

In short ASP.NET web development the next generation version of Microsoft's ASP, is a programming framework used to create enterprise-class web sites that will be totally based on n-tier Architecture to make Microsoft .net Software Development Services and Custom .NET Developmenteasy.

ASP.NET Development Benefits

Rightway solution has been keenly looking out for. Microsoft ASP.NET is a free technology

that allows programmers to create dynamic web applications. The revolutionary technology has been designed to hook up businesses, employees, customers and partners in one loop, through use of web services. It is said to have enough fire power to build, deploy, manage, and use connected, security-enhanced solutions with web services.

What is ASP.NET? ASP.NET stands for Active Server Pages .NET and is developed by Microsoft. ASP.NET is used to create web pages and web technologies and is an integral part of Microsoft's .NET framework vision. As a member of the .NET framework, ASP.NET is a very valuable tool for programmers and developers as it allows them to build dynamic, rich web sites and web applications using compiled languages like VB and C#.

ASP.NET helps to bring out the real world web applications in documentation time. Stretchy Language Options – ASP.NET allows empowering the existing programming language skills. Different classic ASP, which abets barely, interpreted JAVA Script and VB Script at present ASP.NET abets more than twenty five .NET languages which also includes built-in support for C# which is called as C sharp, Visual Basic.NET and JAVA Script and also it does not requires any tool. Thus it gives an extraordinary litheness in the selection of language.

Web development is the process by which you can get more features of innovative technology – web design, back end programming and software solution for more business efficiency, simply get more from your website infrastructure by integrating each element. Skilled ASP.NET web developers are available for ASP.NET software development, ASP.NET website development & ASP.NET programming.

Advantages of ASP.NET:

•Any application can talk to a host of other applications, running on diverse technology and hardware, in turn lowering the operation costs. Consider this one case, wherein the stock management system is connected to the accounting system, resulting in ample savings.

•Bring on one platform all your internal applications, your partners as well as your customers.

•Microsoft Visual Studio® .NET and the .NET Framework supports varied languages, in turn helping developers to focus on work at hand instead of trying to learn a new language that can do the job.

Optimizing Your Asp.Net Pages for Faster Loading and Better Performance

If you read the internet and all of the websites dedicated to Asp.Net you will inevitably read about the wonders of the DataGrid, DataList, and Repeater controls. While each of these has its place, if you are only displaying data there is a much faster and more efficient means to do so.

Let's say you have a page that displays articles based on a query string. Take my article pages for instance. Each article is stored in a database and displayed on the page based on the unique id of the article as stored in the database.

A normal asp page execution procedure goes something like this. The code queries the database based on the Article I.D. and then brings back that information to the page where you display it in the fashion that you would like. This is a fairly straight forward approach with asp and is done all the time.

So how do we speed up our asp.net pages?

Number 1: Use Asp.Net Caching!

This is a no-brainer, and I won't go into the brilliance or details of asp.net caching here because at the time of this writing Google has 2,780,000 articles on the topic. Basically instead of querying the database each time the page is loaded you only query the database once and load that result into the system cache. Subsequent calls to load the page retrieve the data from the cache as opposed to the database which gives you an instant and considerable performance boost. You can then set the cache for how long the cache should store the information as well as many other features. If you are not using the cache, you should be whenever possible!

Number 2: If possible, do NOT use the standard Asp.Net controls.

That's right. The standard asp.net controls are designed for rapid development and not page performance. They allow you to design pages that grab and display data very quickly but their actual performance suffers because of the extra overhead which is there for ease and speed of development time and not page execution speed.

Instead, create either a User Control or even better yet a Web Custom Control which is by far the fastest performance wise and really quite easy to create and use.

Number 3: Use an SqlDataReader or even better yet use a set based command for Sql Server data retrieval and simply execute that one command against the database.

An asp.net SqlDataReader is a fast forward only datareader that closes the connection after it reads the last set of results. Now for my article pages we are only returning 1 particular result. In this case we would opt for the set based command. If you had more than 1 result returned, in your table of contents for instance, you would use the SqlDataReader because you are returning multiple sets of results.

Set based commands are stored procedures that bring back data through parameters as opposed to a result set which then in turn needs to be looped through to obtain your data. So instead of writing your stored procedure like the following which brings back 1 result set:

Select Title, Body, Author
From Articles
Where ArtID = 215

We can write it using a set based command like this.

Create Procedure mvsp GetArticle

@Title varchar(200) Output,
@Body varchar(8000) Output,
@Author varchar(500) Output

As

Select @Title = Title, @Body = Body, @Author = Author
From Articles
Where ArtID = 215

GO

The above query will return only the three parameters called for and not a result or record set so you don't have to then walk through the returned record set that has only 1 result in it anyway. This second little process of work decreases your performance so you should avoid it whenever possible. Combine this technique with the asp.net cache.

Number 4: Use Classes and ArrayLists as opposed to returning an SqlDataReader.

Create a class and then if there are more than one set of results store those results into individual instantiations of that class. Finally store each of those classes into an ArrayList. You can then store only that ArrayList into the asp.net cache. So instead of getting the results back from a SqlDataReader when loading your page you get them from the ArrayList which is stored in the cache. Nice huh?

Finally... you want to incorporate all of these techniques into your final results which would be performed in the following manner and sequence.

On the first time the page loads, query the database and return all of your data storing it into individual classes. Then store each of those classes into an ArrayList. If you only have one single result you may store only the class into the cache. Then take your ArrayList and store it into the cache.

Next create a Web Custom Control and pass the cached ArrayList to the custom control and loop out your data using the HtmlTextWriter which is very fast. Remember each subsequent call to load the page will be called from the cache which stores your ArraList of classes or your single class.

Certainly it takes a significant amount of additional coding to do it in this fashion, especially when you take proper error handling into consideration, but if you follow this approach your pages will be screeching fast, you will immediately notice the difference, and your asp.net pages will execute in the proper sequence - Data handling in the PageLoad function and the html display in the PageRender function.

Further, you will be glad you did and so will your visitors.

Happy Programming!

Creating Sql Database Connection in Asp.net Web Application Through C#

1: Open visual studio 2005 and from FILE select NEW-> WebSite, then from pop-menu select asp.net website (Note: Language must be C#) , then press OK.

2: Now create three textboxes from the toolbox , to remove ambiguity I am using default name for that textboxes and that should be textbox1,textbox2 & textbox3. And also drag & drop the button to the asp.net application.

3: Meanwhile, Open SQL SERVER Management studio 2005 and open adventureworks(or you can create your own database by the Sql command CREATE DATABASE database_name), but here I am using AdventureWorks database.

4: Then create table by clicking right mouse button and form three column, Name them according to your requirement , for your information only I used EID,name,Address. And click save button, then you’ll get a pop up menu where you have to enter the Table Name, for this example I used  students.

5: Now Come Back to Visual studio Application and write the following code in the button_click event

protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection myConn = new SqlConnection();
myConn.ConnectionString = “Connection string(See Below for this — )COPY PASTE  HERE“;

myConn.Open();
string strqry = “Insert into students values (” + TextBox1.Text +
“,’” + TextBox2.Text + “‘,’” + TextBox3.Text + “‘)”;

SqlCommand myCom = new SqlCommand(strqry, myConn);
int numrow = myCom.ExecuteNonQuery();
myConn.Close();

}

Kindly note down the connectionString Syntax, to obtain this string do the following steps:

Step 1 : Go to toolbox and from data section drag & drop SqlDataSource.

Step 2: Then on left clicking the mouse on SqlDataSource , you will get configureDataSource link, Slect this.

Step 3: NewConnection String -> Provide Server Name then select or write database name , i.e. AdventureWorks.

Step 4: TestConnection and then Press OK.

Step 5 : Now you will again redirect to the page that you actually see in the step 2, but this time click + sign before the connection string and from the drop drown hierarchy you will receive the connection string.

Step 6: Just copy and paste this string to the place of connectionstring.

Now debug & run Your application and check it’s effect on the table.
