To remedy these issues, Twitter introduced support for OAuth, which is a simple, secure protocol for granting API access.
OAuth allows a user to connect an application to their Twitter account without having to share their password.
In late 2009, Twitter announced that it was ending its support for basic authentication in June 2010. Website, which uses basic authentication, will no longer work once the cut off date is reached.
When a user visits the demo website for the first time, the Default.aspx page shows a "Sign in with Twitter" button at the bottom of the page. The screen show below shows the demo application after having signed in with the Twitter user aspIntegration.
The Default.aspx page (shown above) includes a text box where the user can enter text that will be tweeted to his Twitter account. The demo's Site.master master page defines the markup and code used to display the visiting user's most recent tweets. The ListView of tweets is contained inside of an UpdatePanel control, which also contains a Timer.
Twitterizer makes it easy to post a tweet on behalf of a Twitter user, which means you can offer users a text box on your website from which they can post tweets. Before you can send tweets on behalf of a user, the user must grant your application access to their account.
The registration form asks for various bits of information - the application name, a description, the organization name, and so forth - fill these in as you see fit. Callback URL - When a user authorizes your application to access their Twitter account they do so from Twitter's website. Default Access Type - choose whether your application requires read-only or read and write access to users' Twitter accounts. After you register your application, Twitter will assign you two important bits of information: a consumer key and a consumer secret. To start the authorization workflow we need to send the user to Twitter's website where they will confirm whether they want to grant our application access to their account. When a user visits the demo application for the first time, a "Sign in with Twitter" image is displayed (see the screen shot below).
When the user clicks the "Sign in with Twitter" image there is a postback and they are redirected to the Twitter website.
The following code is executed from the Page_Load event handler of the Callback.aspx page in the demo. Update method, sending along the access token (which we have cached in the session variable AccessToken) and the text to tweet. Open Website option to open the folder where the files were unzipped, and hit F5 to launch the application. To accomplish this, start by downloading the demo site and unzipping it to some folder on your desktop. Twitter will stop supporting basic authentication and require all integrating applications to use OAuth. Now I know, that it is unlikely that the search engine will discover the duplicate URL’s, but it is better to make sure only one can be accessed, and this can be done by using attribute routing. Also, in my experience I have found that using attribute routing instead of the default route makes it easier to debug routing issues. It’s best practice to have either the www redirect to the none www or the www redirect to the www. The following example shows a rewrite rule that redirect the none www to the www subdomain. The other good thing about the rule above, is it will redirect all domains to the primary domain. Visual Studio Web Deployment with SQL Server Compact- Deploying SQL Server Compact Databases3.

Because we're not using the WebForms model, let's quickly remove the tags for the element. You should be getting used to page declarations (the bit in .aspx pages) by now, so the declaration will come as no surprise. The Literal control is very useful when you want to render something to the page without any extra markup. But if you don't want the span tags at all, for example for the page , you need the Literal control.
This is really just scratching the surface, as it's possible to have multiple master pages (even nested master pages!). As you're familiar with OOP you can see how this can be used to build large-scale web applications. To access your connection string you can use the ConfigurationManager class which we used in part 1 of the tutorial to access global configuration settings.
The object you set up in the brackets is automatically destroyed when your code leaves the end curly brace "}". But there's a much better way to display simple loops, and that's using the Repeater control.
As a Repeater will throw an Exception if an empty DataSet is bound to it, you need to check there is data to be bound first. I think you'll agree that having a control which sets templating for repeating data as easily as that is a massive help to the developer.
Let's pull the last couple of sections together and create a data access class that will simplify connecting to and running commands on your database.
You may notice the new file has an extension of .ascx, this is the extension for user controls. Here you can see instead of a Page declaration we have a Control declaration, but the same Inherits property to bind it to the code-behind file. Here you can see that the public string property I declared in my ShortCode user control class (public string Link;) can be set in a Link property of the control. However it's possible to register your tag prefixes in your web.config file, so you don't have to do it on every page (as explained by Scott Guthrie - that's one blog you'll want to follow). This means that C# is faster (yes, it's true, sorry), and that you can catch a lot of errors in your code *before* you try to run it. There are several other articles which do a much better job at explaining this than I would so I'll just link to them. Follow us on Twitter, or subscribe to the Nettuts+ RSS Feed for the best web development tutorials on the web. Consequently, a user must share her password in order to connect her Twitter account with the application.
The master page and CSS rules define a layout that divides the screen into left and right portions.
We'll explore how OAuth works and how it is handled in the website and through Twitterizer in a moment.
The code below creates such an object, populates its properties, and then caches it in a session variable. The authorization process requires a bit of work, but once you have that token it is good forever, or until the user explicitly revokes it.
If you get an error message of some sort you'll need to figure out what's wrong and fix this before using the demo application. Or even better, replace the default route with a catch all that points to an action that displays 404 not found. For example, assigning [Route("")] to the index action of the home controller will fix the issue above. Perhaps they were Windows desktop application developers making the jump to the web, maybe they had never hand-coded HTML.
For example, the evil javascript:__doPostBack function is a perfect way to make your website impossible to use for a large proportion of the web audience - oh, and search engines as well.


A master page is a template file you can use to encapsulate HTML you use in multiple pages.
Let's have a go at building something that looks more like a real web application, starting with the master page.
Firstly I haven't used the PageJS content placeholder at all - it's quite OK to leave it out entirely (of course nothing will be rendered to the page for that area). You can also set the master page programatically (but this needs to be done in the Page_Init event, as Page_Load is too late in the page lifecycle). Let's create a security class by right-clicking the root of your application and selecting "Add > New file" then choosing "Empty class" from the "General" section and calling it "Security".
I've also added the "static" keyword to the property and method, and I've made the CheckSession() method public. As you're fully aware of the advantages that OOP can give you for abstraction, encapsulation and inheritance you'll see how powerful this is. You can do this in web.config, add this code inside the "configuration" section (the MySQL and SQL Server code should be pretty obvious).
In the code above the results from the database query are fed into a DataSet, which is an object containing one or more tables, each table containing rows and columns.
One thing to note with the Repeater control - if you bind a DataSet to it by default the first table is used. As the code says, the ExecuteNonQuery method executes a query and returns the number of affected rows. It would be easy for you to extend this data access class to have more useful properties and methods for your applications. Firstly add a new file of type "User control with code-behind file" and call it "ShortLink". We also have a standard element with the runat="server" property to make it a server-side control. And the best thing about user controls is, because they are just like pages (without , and tags) you can put anything you like in them. Rather than PHP, which is compiled into language the computer can understand at runtime, C# is pre-compiled (or sometimes compiled on first run) and saved in assemblies for the computer to process. It's also worth stressing that you need a good grasp of object oriented programming (OOP) to continue. For example, your master page could contain the header, menu and footer of your pages, while your normal .aspx pages contain the actual content on that page. In that directory create a new master page by right-clicking on the Master_Pages folder, selecting "Add > New file" then selecting "Master Page with Code Behind" and call it "DefaultMaster".
But if we're going to use objects, we really need some serious data to model in our objects.
The Repeater control allows you to "bind" data, for example from a DataSet, and display it in a looped manner. If you're using stored procedures instead of inline SQL to run commands against your database you can return multiple tables, meaning you can load several sets of data for use in a page at once. In fact it would be possible to write an entire application in user controls, including the relevent controls in your page depending on some parameters passed to it. However I've found many good things in the framework, and have come to appreciate the power of the C# language - without losing my love for PHP.
It also means you can't do live hacking of your code-behind files in a running application. The fix (for me) was to manually add the reference by right-clicking the References folder in my application and going to "Edit references". Using this simple control gives you an easy way to display repeating data, with complete control over the resulting HTML - just like you would do in PHP.
