Issues with ajax controls when upgrading from VS 2005 to VS 2008

Issues with ajax controls when upgrading from VS 2005 to VS 2008:


I have developed a website in Visual Studion 2005 (I mean to say DotNet Framework 2.0). I have used ajaxcontroltoolkit and developed ajax enabled website with all the ajax controls (e.g., accordian, asynchronous fileupload, calender extender etc). But I then realized the advantages of DotNet Framework 3.5 , So I just installed VS 2008 and opened my previous project in VS 2008. It asked me to convert to .NET framework 3.5, I just clicked next ->next and completed the conversion.

But then the problem raised with the ajax. Following may be the list of errors you may face when build the project in VS 2008.

A ScriptManager is required on the page to use ASP.NET AJAX Script Components. - error


Unable to cast object of type 'System.Web.Configuration.ScriptingAuthenticationServiceSection' to type 'System.Web.Configuration.ScriptingAuthenticationServiceSection'.

How to Deploy ASP.NET Web Application in Hosting Web Server

How to deploy ASP.NET website 


All the efforts have been made to create a beautiful website at the end of the day. This is good enough to see your output in your local machine (local host). But this is not why the web applications (or websites) are actually meant for. Then, how do you make your website (your personal pages) to the general public. Then you say deploy the website (web application) to a hosting server.

Here comes the difficulty for layman (even, few of us who are familiar with technology) how to approach.

So I decided to post a details explanation with examples and screen shots to explain the same.

There are 2 ways you can publish or deploy your website

1. Deploy the source files to the web server
2. Deploy the pre-compiled website (Recommended)

The following are the easy steps to deploy your website (or web application) with the pre-compiled way (Will discuss the first method later)

Orkut - What is Bom Sabado!

Orkut - What is Bom Sabado!

Orkut has flooded with the Bom Sabado scrap messages from this morning. This is a type of spam (virus) that is been fed into the accounts. It is being looked into by the Orkut team (Google). Please be patient, because almost all the accounts have been affected with this.
Till now there is no evidence that the private information loss / any other mischief by the virus. The patch work is being done so we can wait for 1 or more days to get this problem solved.

Precautions:

• Don't open the orkut account till this problem (Bom Sabado) has been resolved.
• Change the Google account password
• Also, make the status invisible (don't login to chat if possible) till it is solved.
• Don't reply to the message that you recieved ("Bom Sabado")

The Five levels of CMM

Level One
Company has no standard process for software development. Nor does it have a project-tracking system that enables developers to predict costs or finish dates with any accuracy.

Level Two
Company has installed basic software management processes and controls. But there is no consistency or coordination among different groups.

Level Three
Company has pulled together a standard set of processes and controls for the entire organization so that developers can move between projects more easily and customers can begin to get consistency from different groups.

Level Four
In addition to implementing standard processes, company has installed systems to measure the quality of those processes across all projects.

Level Five
Company has accomplished all of the above and can now begin to see patterns in performance over time, so it can tweak its processes in order to improve productivity and reduce defects in software development across the entire organization.

how to remove FREE MOBILE RECHARGE virus in orkut

REMOVE FREE MOBILE RECHARGE VIRUS in orkut:

This article has the reference to the previous post ORKUT SECURITY TIPS. In the previous article I warned everyone not to run script (Javascripts) in the browsers (In which you opened orkut account) address bar. But still most of our best buddies have done it successfully ;-)

So I need to write this post for them. Try to follow these steps and never execute or run any scripts in the browser window (whatever may be the situation). This even some times deletes your account. In most worst cases the hacker may mis use your account details for illegal purposes (black mailing, sending adult content to your friends in your account)

▪ What we the users can do to stop this ?


→ Report the URLs at http://www.google.com/safebrowsing/report_phish/

→ Stop script (running javascripts in Orkut).

→ Tell freinds about these scams and to be safe.

→ Delete the auto-generated scam thread in the communities.



▪ What happens when the script runs ?


→ Edit your about me, status and even picture.

→ Send scraps to your friends to run the script.

→ Post threads on the communities you joined.

→ Comment on photos of your friends

→ Send testimonials etc.



▪ I have already run the script. Now what can i do ?


→ Clear cookies and Cache

→ Change your account settings ie, password & security question.

→ Edit your about me, status etc which was changed by the script.

→ Never run any type of scripts again.

Ten most commonly used internet passwords

 A data security firm has unveiled the ten most commonly used passwords on the web.

To reach the conclusion, Imperva analysed around 32 million passwords that had been exposed in a recent hack of the RockYou website.

Last year a hacker had breached the site’s company database, gaining access to the unencrypted usernames and passwords of all its 32 million users.

Now, after studying the breach the firm has come up with a list of the most commonly used passwords which website users should avoid, reports The Telegraph.

“Everyone needs to understand what the combination of poor passwords means in today’s world of automated cyber attacks: with only minimal effort, a hacker can gain access to one new account every second-or 1000 accounts every 17 minutes,” said Amichai Shulman, Imperva’s chief technical officer.

“Employees using the same passwords on Facebook that they use in the workplace bring the possibility of compromising enterprise systems with insecure passwords, especially if they are using easy to crack passwords like ‘123456’,” he added.

“The problem has changed very little over the past 20 years. It’s time for everyone to take password security seriously; it’s an important first step in data security,” he said.

The ten most commonly used passwords analysed in the study were:

1. 123456

2. 12345

3. 123456789

4. Password

5. iloveyou

6. princess

7. rockyou

8. 1234567

9. 12345678

10. abc123.

Clipboard Hack Problem Internet Explorer Security Tip

Clipboard Hack Problem - Shocking news about CTRL+C:  View Demo

CTRL + C is the most useful action that we use everyday. But, I have found this to be very dangerous with internet explorer and netscape navigator. Because, your clipboard text (which you have copied by pressing CTRL+C on your system) can be easily retrieved by the websites, if they really wish to do so.

Imagine a scenario, when you tried to copy your account number or password or any other personal information on your system, it will be saved (or copied) into the clipboard (temperory buffer in your operating system). Then if you open the website (one who intentionally try to access your personal information, i.e. the hackers) knowingly or unknowingly. Thats is it, they are done with their work. You need not do anything on your own. Your information is copied and they can access the information from the clipboard and use it for illegal activities.

So be very careful my dear friends. This will work in internet explorer and netscape navigator only. This is not possible with google chrome,mozilla firefox or any other browser. Remeber, today the most used browser around the world is internet explorer. So just avoid these kind of attacks and be on safe side.

Follow the steps below to safeguard yourself from clipboard hack:

1. GoTo internet option --> Security
2. Press custom level
3. Under allow paste operations via script, Select "Disable" radio button

 Your are done with the security setup. Now, your browsing is safe than before. Enjoy the browing

Orkut security tips: Secure your orkut account

Due to orkut's open nature, users can unwillingly infect their computers with viruses, spyware, adware, and other unwanted junk. This can result in strange behavior, such as sending unintended scraps to friends that may even infect more viruses. To help prevent this from happening, I recommend the following safe practices:

    * Don't click on any link (e.g., free recharge coupon kind of) you suspect to be malicious, even if sent by someone you really trust.
    * Never select the "remember me" option when you're using a public or shared computer.
    * Scan your computer regularly for viruses, spyware and adware.
    * Never run any script while logged into orkut, no matter what it claims to do. Usually you will be asked to copy and paste a code in your web browser, remember to never do so!
    * Always check your browser's address bar to make sure you enter your sign-in information only on www.orkut.com and other Google properties.
    * Change your password regularly and keep it secret.

Additionally, orkut or google will never send you spam emails asking you to download anything or to send them personal information, such as your password or bank account information. Orkut is a free service, and it will remain safe with your help.

Enjoy Social Networking :) :)

Working with Delegates in C#

Abstract In this article I'll discuss what delegates are with lucid code examples. Introduction

Delegates in C# are like functions pointers in C/C++. A multi cast delegate can refer to several methods. A delegate can be used to invoke a method, the call to which can only be resolved or determined at runtime. This article discusses what delegates are and how they can be used in C# with lucid code examples.

Understanding Connection Pooling in .NET

Abstract
Connection Pooling can increase the database performance to a huge extent. This article discusses what Connection Pooling actually is, how it can boost the performance of database access and how we can create a Connection Pool in .NET and add and remove connections to it.

Introduction

Connecting to the database is resource intensive and a relatively slow operation in an application but the most crucial of them all. A Connection Pool is a container of open and reusable connections. A Connection Pool is released from the memory when the last connection to the database is closed. The basic advantage of using Connection Pooling is an improvement of performance and scalability while the main disadvantage is that one or more database connections, even if they are currently not being used, are kept open. The Data Providers in ADO.NET have Connection Pooling turned on by default; if you need to turn it off, specify Pooling = false in the connection string being used. Connection Pooling gives you an idle, open, reusable connection instead of opening a new one every time a connection request to the database is made. When the connection is closed or disposed, it is returned to the pool and remains idle until a request for a new connection comes in. If we use Connection Pooling efficiently, opening and closing of connections to the database becomes less resource expensive. This article discusses what Connection Pooling is all about and how Connection Pooling can be used efficiently to boost the performance and scalability of applications.

Working with Images Using .NET

Some applications, be it desktop or web, require working with images.  Aptly speaking, the good paradigm is banking applications.  Withdrawal of an amount of money from a bank account requires signature verification of the account holder.  Normally, specimen signatures of customers are archived as images in such applications.

Working with Images Using .NET

Abstract

In this code snippet I will examine how to work with images using Visual Studio .NET 2003 and SQL Server 2000 database.


Introduction

Some applications, be it desktop or web, require working with images.  Aptly speaking, the good paradigm is banking applications.  Withdrawal of an amount of money from a bank account requires signature verification of the account holder.  Normally, specimen signatures of customers are archived as images in such applications.

There can be a couple of ways to work around to store images.  One is typically to tag each image with a unique identifier and save the image at a physical location accessible by the application. Store that unique identifier and the physical absolute/relative path in a database table.  Now, when the application looks in for a given identifier from database table then the path against the identifier can be pulled from the table and uses that path in any image control to display the image.

Multithreading with an Example of .NET Application

Abstract
In this article I will discuss the basics of multithreading and how it could be effective over a single thread application. It also includes the advantages and disadvantages of multithreading. The article includes the complete .NET project for creating a simple multithreaded application.

Introduction

Threads are also known as lightweight processes.  However, if we go into depth then we would know that a thread is not actually a process; rather it provides ways for executing different parts of a program.  Now let us discuss what it actually means by multithreading.  Multithreading (as the name suggests multi+threading) is nothing but an efficient execution of multiple threads at a time to enhance the performance of the application.  For example, we are doing a file copy operation with a status bar on UI indicating the completion percentage.  Here we need to keep track of how much file size is copied and at the same time we also need to advance the progress bar accordingly.  This can not be done efficiently in a single thread and you have to use multiple threads.

The above example shows just one instance where we are forced to use multithreading.  However, when we are not forced we can also use this for the betterment of the application performance. And of course, all this depends on how effectively the thread is implemented in an application.  Most of the developers do not use multithreaded applications and continue with a single thread.  However, the efficient use of threads can give birth to a highly powerful application.

Localization in ASP.NET 2.0 (advanced)

Abstract
This article will cover some more of the Visual Studio 2005 enhancements for making Resources easier to include in your project, as well as showing the various ways that Resources can be included through code within your applications.

In the previous article, the Visual Studio .NET 2005 features for easily Localizing a web site were explored without using any code.

This article will cover some more of the Visual Studio 2005 enhancements for making Resources easier to include in your project, as well as showing the various ways that Resources can be included through code within your applications.

In Visual Studio 2005 Web Site's there is the concept of a "Resources" folder living on the root of your web site. In this folder you can place, surprisingly enough, resources. Unlike the Resources discussed in the Previous Article, any Resources placed in the Resources folder have scope across the whole Application, in that they can be accessed from any Web Form or Code, whereas the Resources stored in "LocalResources" folders are only associated with a specific .aspx.

Visual Studio 2005 not only supports the use of the Resources folder, it's embraced and encouraged, this is done by offering Developers Strongly Typed access right in to their Resource files through the Resources Namespace, for example if there is a .resx in the Resources folder called "Bob" and within Bob.resx there is a Resource String called "Alice" with a value of Cake, in your .aspx all you need to do to access the Resource String "Alice" (with full intellisense of course) is type: -

string AlicesFavFood = Resources.Bob.Alice.ToString();

Oh, ResGen is Dead, RIP ResGen.

Now you've picked yourself up off the floor after that moment of enthusiastic bouncing let's continue.

The above happens without the need to recompile, all that you the developer needs to do, is Save the .resx file and you instantly get all the Intellisense within your application.

Intellisense on your Resources is really usful, especially if you're no the person that put together the Resource files, this allows you to quickly get hold of the right Resources within your applications. However. And it's a Big However. To me, it's very rare that I will know the name a of Resource for my controls before I come to actually write the controls them selves, this leaves us in somewhat of a Chicken and Egg situation.

I see this functionality being useful mainly where you have General resources, such as you might have on an e-commerce site, strings such as "Price", "Shopping Basket" and "Checkout" might be strings you regularly use in many different e-commerce applications, I see having a Resource file that you drop in to each of your projects with General Resources being used with the Intellisense, otherwise I think it may be an otherwise unused piece of Visual Studio 2005 functionality.

Accessing resources in code can be achieved in a variety of ways, mainly depending on the source of the Resource. Along with the meta Resources discussed in the previous article it's also possible to explicitly include Text from Resource Files stored in the LocalResources folder as so: -

Or in Code Beside/Behind you can access the LocalResources of a page by using the GetPageResourceObject() method of the Page.

string LocalResource = (string)GetPageResourceObject("LabelResource1.Text");


It's also possible to Localize static content, i.e. just basic strings that don't need to have Server Side access.

Some Default Content

Using Application level resources is possible through the Resources member as shown above, but it can also be accessed programatically in pages via the GetAppResourceObject() method, as so: -

string ApplicationResource = (string)GetAppResourceObject("Bob", "Alice");

As well as the Programatic access, it's possible to retreive the Application level Resources declaritavly like this: -

So there you have some more of the new features in ASP.NET 2.0, everything about Localization in ASP.NET 2.0 is so much easier. The next articles in this series will discuss .Resource files in ASP.NET 2.0 and Database stored Resources.

How to do a language switch in a master page.

As the rap song goes: “There’s no champagne in the champagne room...”, there is no page in MasterPage. It derives from UserControl. As such it does not support the InitializeCulture() method for us to override as described in this post. Newbies love master pages, even though half the time they do not understand them, so here is a solution, compounding the misuse, but here it goes.

Don't try to access controls in InitializeCulture()

InitializeCulture() is an empty protected virtual method in the Page class. So it is empty in the inherited class too that the IDE generates. When overriding it there is no need to call the base method.

What is noteworthy is the fact that is IS VERY EARLY ON, in the page lifecycle. Way before any controls exist. So most postback handlers that depend on controls are worthless for setting the culure in the thread, BECAUSE THEY ARE ALL LATE.

So how do we do a dropdown or a listbox to switch languages? Isn’t the dropdown a server control? Here is the magic that keeps so many people, that are enamored with localization, stumped.

There is a Http collection called the “form data set”  which is passed in every request. It is a name value collection. The keys are the name attributes of the html elements in the form tag. The values depend on the element. For a dropdown that value is the selected value (if no value, then the selected text, if none then the first item) These are what is known as “successful control” rules. At the time of submission the browser gathers up these values and submits the collection along with the request.

Notice no aspnet so far. The aspnet representation of that collection is the HttpRequest.Form property. Its type isSystem.Collections.Specialized.NameValueCollection and thenicest thing is, IT HAS NOTHING TO DO WITH SERVER CONTROLS. How do we know? Just try retrieving the values from a regular html form element without runat=server and you will know; all without the aspnet runtime doing anything more than reading the browser request.

So we get it for free, and we get it right away and we get it every time.This is the key concept. Plus the collection items map to form elements. So we can grab values out of it inside the InitializeCulture() method and never wait for the full controls to be built. The HttpRequest is exposed as the Request property of the page class.

the server control
<asp:DropDownList runat="server" ID="ddl" AutoPostBack="true" />

renders as the html element, with both the name and value attributes the same(provided not declared in a template like a user control or a master page)
<select name="ddl" id="ddl">

Here is a sample of that code.   Here is a video demo

EVERY PAGE NEEDS THE THREAD SET DE NOVO, because the thread dies at the end of the page lifecycle. So it becomes a pain to do this code over and over again. We can inherit from our own page class that overrides this method and never have to see it from code behind. The problem is that OO intimidateas the hell out of newbies. Also the class would be too closely coupled with the form element under question and I myself have a paranoia of coupling business logic. User controls and master pages do not support the InitializeCulture() method.
So System.Globalization is really in the way of code globalization! ;)
Here is a solution how to do a language switch dropdown in a master page with globalized code.

Localization in ASP.NET 2.0

Abstract

In this article, I am going to present the new localization feature provided by .NET framework 2.0. Throughout the article, the new tools provided by Visual Studio 2005 to support localization will be highlighted and used to show you how easy it is to localize your web applications with ASP.NET 2.0.


Introduction

A few years ago we started hearing new terms in economics about globalization and integration of international markets.  This made many large business companies begin thinking of how to attract markets from all over the world and not only from domestic markets.  The first idea that might come to the company is to have a Multilanguage website; clients from a set of targeted countries can localize their website to their own native language.

ASP.NET 2.0 comes with a rich environment that makes localization of web applications a very easy task to perform.  There are two main kinds of localization in ASP.NET 2.0: implicit localization and explicit localization, each of which will be discussed in more detail throughout this article.

Preliminary Steps

When you think of localizing a web application, some preliminary steps should be taken into account.  Those steps can be summarized in two main points:

Globalization: The main strategy of the web application is set in this step.  The web application architect shall ask the following questions: How many countries or languages are targeted in the application?  What sections are to be localized?  Etc.  In addition, gathering of resources for all the predetermined languages should be collected before any implementation starts.

Localization: The actual localization and implementation through code is done in this step.  The resources needed are supplied to the web application and then it is the developer's role to allow the application being worked on to support all the predetermined languages required by their application.

Localization and Visual Studio 2005

Visual Studio 2005 now ships with a new resource editor that allows you to easily add/remove/update any resource key in any ASP.NET resource file (.resx).

In addition, Visual Studio 2005 makes generating resource files an easy step to do by just going to Toolsà Generate Local Resource while your WebForm is in the Design view.

Moreover, Visual Studio 2005 provides two ways of localizing a web application.  The first is using Local Resources; a local resource is a resource file attached to a WebForm.  Or you could use   Global Resources in which you can combine all common resource keys used by several ASP.NET web forms into a single resource file.

The above tools and concepts will be revisited throughout this article while creating and manipulating resource files.

Working with Local Resources

In this section we are going to show how easy it is to generate a local resource file for any ASP.NET web form.  By local resource we mean that a single resource file is in a many to 1 relationship with the ASP.NET web form.  In other words, if you have a Label server control and you want to show some text in this label for each culture available in the web application, then you place a resource key in an accompanying resource file for a specific culture.  At run time, the resource key will be looked up in the culture-specific resource file, evaluated and replaced with the proper text translation.  You can have several resource files for the same ASP.NET web form, each representing a specific culture.

To generate a local resource file in Visual Studio 2005, start by creating a new website.  Open the default.aspx page and add few controls, including the following:

Label Server Control, with an ID of lblName

TextBox Server Control, with an ID of txtName

Button Server Control with an Id of btnSubmit

The figure below shows what the default.aspx page looks like.



Make sure your default.aspx page is in the design view.  Then go to Tools à click on the Generate Local Resource command.

You will notice two changes to your web application and ASP.NET page.  First of all, a new "system" folder has been added in the web application’s root folder called App_LocalResources.  The App_LocalResources folder has been newly added to the ASP.NET 2.0 web application. This folder holds all the resource files for all the ASP.NET web forms.  The ASP.NET runtime uses the .NET framework, ResourceManager, to perform resource key lookups.  The ResourceManager will look at the App_LocalResources folder at all times.  This means that any resource file located outside this folder will be ignored.

You can easily add a new resource file to that folder to represent any additional language for your web application by simply copying the default resource file of an ASP.NET form and pasting it with a new name.  For instance, if you have the default.aspx.resx resource file, which represents the English language, then you have English set as the default language of your machine.  Now you want to add the Arabic-Lebanese language for your web application.  You simply copy the default.aspx.resx and rename it to defaut.aspx.ar-LB.resx.  This way you have added support for a new language.  The only thing left to do is to change the values of every resource key inside the resource file added.

Next, open the source view of the default.aspx page and you will notice new tags have been added to the controls that require localization.

Listing 1


<form id="form1"runat="server">
<div>
<asp:Label ID="lblName"runat="server"meta:resourcekey="lblNameResource1">asp:Label>
<asp:TextBox ID="txtName"runat="server"meta:resourcekey="txtNameResource1">asp:TextBox><br/>
<br />
<asp:Button ID="btnSubmit"runat="server" Text="Submit"meta:resourcekey="btnSubmitResource1" />div>
form>

As you can see, a “meta:” tag has been added to every server control together with a resource key that corresponds to the resource key entry in the default.aspx.resx resource file.

The snapshot of the default.aspx.resx is shown below.

Figure 2




For each server control a single resource key has been added with multiple properties of .Text and .ToolTip.

As mentioned above, at runtime the resource key will be evaluated and the corresponding text in the resource file will be displayed.

Now we can add the Text and ToolTip values for every control in the resource file.  However, before we can run this page and see how it is being localized automatically, we have to specify the Culture and UICulture properties in the Page directive.  This way, the ASP.NET runtime will know the culture used and apply the specific resource file for that chosen culture.

To do so, add the following to the Page directive:

Listing 2


Culture="auto:en-US" UICulture="auto"

We have set the Culture to be auto and have a default value of en-US and the UICulture set to auto.  Having an auto property means that the request will automatically detect the culture specified on the client browser.

Run the application and you will see that the server mainly controls the Label and that the Button Text property will be evaluated based on the culture and the resource file of that culture.

To support an additional culture, copy the original resource file as mentioned above and add your translation for the entire resource key and test it in your browser.  To test your application with other cultures, refer to the following: Setting a Preferred Language in Internet Explorer.

Working with Global Resources

As mentioned above, the Local Resources are in a many to 1 relationship with ASP.NET web forms.  In some cases, your ASP.NET web forms in an application might share a set of resource keys.  Instead of having redundant data in your resource files, ASP.NET 2.0 introduces the App_GlobalResources folder which lets you place all the global resources, i.e. resources shared by some ASP.NET web forms, in one location.

To create a new global resource, right click your web application root, add an ASP.NET Folder and choose App_GlobalResources.  Then right click this folder and add a new Resource file.  The structure of this resource file is the same as the structure of the resource files placed inside the App_LocalResources.  However, the name of this file can be any meaningful name and is not limited to the name of the ASP.NET web form.  This file, as mentioned above, will hold shared resource keys for several ASP.NET web forms.

To have the same resource file available for several languages, you need to follow the same steps mentioned while discussing the local resources.  The default global resource file is named resource.resx and the French version is written as resource.fr.resx.

Add a new Label Server control to the default.aspx page as:

Listing 3

<asp:Label ID="lblwelcome" runat="server"/>

Inside the resource.resx and resource.fr.resx files add one resource key called “welcome.”

English:

Key: welcome

Value: Welcome to our website

French:

Key: welcome

Value: Bienvenue à notre site Web

To link the global resource to the above label, we need to do the following:

Right click on the label in Design view, click on properties and then choose Expressions.  A pop-up window is then opened for you so choose from the Bindable properties, Text property and form the Expression Type, Resources.  In the Expression Properties you set the ClassKey to be resource.resx and the ResourceKey to be welcome.

You can see now how the label server control looks.

Listing 4

<asp:Label ID="lblwelcome"runat="server" Text="<%$ Resources:resource, welcome%>">asp:Label>

Instead of having implicit localization as the case of local resources, the explicit localization in global localization is done by evaluating an expression and giving this expression the original resource name and the resource key in that resource file.

Now, run your application in a browser and try to change the default culture of your browser from English to French and see how the text inside the label changes as specified in the two resource files mentioned above.

CurrentCulture and CurrentUICulture

Before going on with this article, let us stop and discuss the two main properties of concern, mainly the CurrentCulture and CurrentUICulture.

CurrentCulture and CurrentUICulture are both of the type CultureInfo which belongs to the System.Globalization.

CurrentCulture and CurrentUICulture are both properties of the current thread represented by System.Threading.Thread.CurrentThread.CurrentCulture and System.Threading.Thread.CurrentThread.CurrentUICulture

CurrentCulture is used mainly to format the Dates, Currencies, etc.  For that reason, it should be set as specific and not left as neutral.  For instance, you need to set the CurrentCulture as:

Listing 5

System.Threading.Thread.CurrentThread.CurrentCulture= newCultureInfo("ar-LB");

We have set the current culture to be a specific culture, Arabic - Lebanese.  So make sure to always be specific in specifying the CurrentCulture.

CurrentUICulture is mainly used for language/text translations.  The ResourceManager is based upon the CurrentUICulture.  It does not matter whether the culture set here is specific or neutral.  For instance, either ar or ar-lb works fine with the CurrentUICulture.

Listing 6

System.Threading.Thread.CurrentThread.CurrentCulture= newCultureInfo("ar");

Programmatically Setting Culture and UICulture

In the above discussion, we have seen that the Culture and UICulture properties inside the Page directive were set to "auto."  In this section we will learn how to set both properties programmatically inside our VB.NET or C# code.

Create a new ASP.NET web form and add the following code:

Listing 7

<asp:DropDownList ID="ddlLanguage"runat="server" AutoPostBack="True">
<asp:ListItem Selected="True"Value="auto">Autoasp:ListItem>
<asp:ListItemValue="en-US">English (US)asp:ListItem>
<asp:ListItemValue="en-GB">English (UK)asp:ListItem>
<asp:ListItemValue="ar">Arabicasp:ListItem>
<asp:ListItemValue="fr">Frenchasp:ListItem>
asp:DropDownList>

This DropDownList lists a few options to change the default culture.  One of the methods of the Page class is called InitializeCulture().  This method is being executed in the early stages of the page creation.  It is the responsibility of this method to set the Culture and UICulture of the current request.  We will override this method to build our own logic in setting the above two mentioned properties based on the selection from the DropDownList.

Copy this code and paste it inside your code behind class.

Listing 8

protected override void InitializeCulture()
{
  string lang =Request["DropDownList1"];


  if ((lang != null))
  {
    if (lang != "")
    {
      Thread.CurrentThread.CurrentUICulture =new CultureInfo(lang);
      Thread.CurrentThread.CurrentCulture =CultureInfo.CreateSpecificCulture
        (lang);
    }
  }
}

In this piece of code, we are first getting the selection from the language DropDownList.  Notice that we did not use the DropDownList properties to access the selected option; this is done on purpose, since the first time the page is visited the DropDownList will not be created.  We use the Request object to access the form's controls.

The CurrentUICulture property is set to the language selected.

The CurrentCulture, as mentioned above, should always be set to a specific culture.  Keeping that in mind, we have to use the static method of CultureInfo object, CreateSpecificCulture().   This takes as an input a parameter specifying the culture and returns a CultureInfo instance having a specific culture set.

Once a culture is chosen from the DropDownList, the current Culture and UICulture will be set accordingly.


Conclusion

We have presented the new localization features in ASP.NET 2.0.  Visual Studio 2005 has been improved to give a better experience in many aspects, mainly the Localization of web applications.  Two new features in ASP.NET 2.0 Localization, Implicit and Explicit localization, have been discussed.  A distinction between CurrentCulture and CurrentUICulture was given showing the similarities/differences and the effect of each of them.  Finally, a programmatic way of setting the CurrentCulture and CurrentUICulture was shown.

Hope you enjoyed this article.

Understanding ASP.NET View State continued...

The Role of View State

View state's purpose in life is simple: it's there to persist state across postbacks. (For an ASP.NET Web page, its state is the property values of the controls that make up its control hierarchy.) This begs the question, "What sort of state needs to be persisted?" To answer that question, let's start by looking at what state doesn't need to be persisted across postbacks. Recall that in the instantiation stage of the page life cycle, the control hierarchy is created and those properties that are specified in the declarative syntax are assigned. Since these declarative properties are automatically reassigned on each postback when the control hierarchy is constructed, there's no need to store these property values in the view state.

For example, imagine we have a Label Web control in the HTML portion with the following declarative syntax:

  Text="Hello, World!">

When the control hierarchy is built in the instantiation stage, the Label's Text property will be set to "Hello, World!" and its Font property will have its Name property set to Verdana. Since these properties will be set each and every page visit during the instantiation stage, there's no need to persist this information in the view state.

Understanding ASP.NET View State continued...

Stage 0 - Instantiation

The life cycle of the ASP.NET page begins with instantiation of the class that represents the requested ASP.NET Web page, but how is this class created? Where is it stored?

ASP.NET Web pages, as you know, are made up of both an HTML portion and a code portion, with the HTML portion containing HTML markup and Web control syntax. The ASP.NET engine converts the HTML portion from its free-form text representation into a series of programmatically-created Web controls.

When an ASP.NET Web page is visited for the first time after a change has been made to the HTML markup or Web control syntax in the .aspx page, the ASP.NET engine auto-generates a class. If you created your ASP.NET Web page using the code-behind technique, this autogenerated class is derived from the page's associated code-behind class (note that the code-behind class must be derived itself, either directly or indirectly, from the System.Web.UI.Page class); if you created your page with an in-line, server-side "script" block, the class derives directly from System.Web.UI.Page. In either case, this autogenerated class, along with a compiled instance of the class, is stored in the WINDOWS\Microsoft.NET\Framework\version\Temporary ASP.NET Files folder, in part so that it doesn't need to be recreated for each page request.

Understanding ASP.NET View State

Introduction

Microsoft® ASP.NET view state, in a nutshell, is the technique used by an ASP.NET Web page to persist changes to the state of a Web Form across postbacks. In my experiences as a trainer and consultant, view state has caused the most confusion among ASP.NET developers. When creating custom server controls or doing more advanced page techniques, not having a solid grasp of what view state is and how it works can come back to bite you. Web designers who are focused on creating low-bandwidth, streamlined pages oftentimes find themselves frustrated with view state, as well. The view state of a page is, by default, placed in a hidden form field named __VIEWSTATE. This hidden form field can easily get very large, on the order of tens of kilobytes. Not only does the __VIEWSTATE form field cause slower downloads, but, whenever the user posts back the Web page, the contents of this hidden form field must be posted back in the HTTP request, thereby lengthening the request time, as well.

This article aims to be an in-depth examination of the ASP.NET view state. We'll look at exactly what view state is storing, and how the view state is serialized to the hidden form field and deserialized back on postback. We'll also discuss techniques for reducing the bandwidth required by the view state.

What architectures can be followed to develop an ASP.NET application?

Hi Everyone,
Today we are going to discuss the architecture that we follow generally to develop an ASP.NET application. Most of you have worked with ASP.NET applications and you might have already developed so many websites, but have you ever thought of any standard way that can be followed to develop an application in ASP.NET.
There are many standard ways that we follow today. Each company or an organization will follow their own coding standards, but most of them have common ways of developing an application.
Now I am going to show you the standard that we follow in our applications. I don't say this is the only way that can be followed. But this is definitely a good way to start with an ASP.NET application.

What are the components of dotnet framework?

Hi guys,
In the last article we have discussed about the introduction to the dotnet framework and what exactly the dotnet framework is all about! What the dotnet framework is and what not!

Now we will continue of discussion with the components of the .net framework and we will see a sample program in c#.

Various components of .NET framework are:

• Common Language Runtime (CLR)
• Base Class Libraries (BCL)
• Framework Class Library (FCL, it is the superset of BCL above)

The following picture gives more idea

What is actually the DotNet Framework is ?

Hi guys,
               How are you all? I am doing good. Anyway straight to the point. I want to make clear of some doubts that so many newbies to dotnet world are facing today.


What exactly the dotnet framework is?
The dotnet framework is not a programming language (I want to stress the word NOT here). Because i heard from so many people saying that ' I am learning new language that is dotnet'. I am sorry if you also think the same way. Its a blunder if you say dotnet is a programming language.

Okay, we have concluded that donet is not a programming language, then what is it? Yes dotnet is a framework which includes a runtime (CLR short form for Common Language Runtime) and the base class libraries (libraries are nothing but the predefined classes and functions like header files in c and c++). DotNet framework also includes other components which we will discuss later ( you may be confused with all of them in the beginning).

How to convert string to integer in c# without the predefined functions or methods

Hi guys,

Here is an interesting post for you all. How to convert a string input (e.g. "123", "325", or "1346" ) to an integer without using the predefined or library functions provided by dotnet framework (or c# language library functions).

Its pretty easy one to implement once you get an idea about it.

Here is a sample code for converting string to an integer using the technique "ascii characters".
