ASP.NET PDF Viewer using C#, VB/NET

You can access site information by navigating to Configuration Site information. Many of the settings on this page are configured during the initial site installation, such as the site name and e-mail address. The site name is used in a number of places in your web site, including the page title, header (if the theme is configured to display the site name), and registration and cancellation e-mails. The e-mail address is used as the From address in all automated e-mails. I usually set up an e-mail account such as admin@example.com or webmaster@example.com for this field. It is also recommended that you use the web site s domain URL to reduce e-mails being tagged as spam. The slogan is displayed in the page title on the homepage or, if the theme is configured, in the header (see Figure 3-2). I have found that writing a slogan using search-relevant keywords helps increase search engine ranking.

A switch statement lets you specify a list of expected values, and what to do for each value. The values can be either strings or integral types. (Integral types include int, short, etc. you cannot switch on floating-point numbers. Enumeration types, which are discussed in 3, are considered to be integral types for the purposes of a switch statement.) We can use this to rewrite Example 2-10 as shown in Example 2-11.

In the source code for this book, we ve included a sample Visual Studio solution that you can run to perform a simulated, local XSS attack. It contains two simple ASP.NET MVC 2 applications. One is vulnerable to XSS attacks in several widely used browsers. It features a simple comment submission page. We ll submit JavaScript as part of the comment, and our vulnerable website will render the JavaScript as if it were legitimate. The other website is the attacker. It simply collects submissions so we can see if our attack worked.

string raceStatus = args[3]; switch (raceStatus) { case "YellowFlag": Driver.TellNotToOvertake(); break; case "SafetyCar": Driver.WarnAboutSafetyCar(); break; case "RedFlag": if (ourDriverCausedIncident) { Factory.OrderNewCar(); Driver.ReducePay(); if (feelingGenerous) { Driver.Resuscitate(); } } else { Driver.CallBackToPit(); } break; default: Driver.TellToDriveFaster(); break; }

The break keyword you can see at the end of each case is present mainly for consistency with other C-like languages. In C and C++, if you leave off the break, the code will fall out of one case through to the next. So if we left off the break in the YellowFlag case, we d end up telling drivers not to overtake and then warning them about the safety car. This would be a bug and in general, you almost always don t want fallthrough. It s unfortunate that in C and C++ fall-through was the default. C# changes this: if you want fall-through you must ask for it explicitly by writing goto case "SafetyCar". But despite fall-through no longer being the implicit default, you still need to write the same break statement as you would in other C-family languages when you don t want fall-through if you leave it out you ll get an error.

You might be wondering what is the point this does exactly the same as Example 2-10, so why do we need a different syntax As it happens, we don t there s nothing you can do with switch and case that you can t do with if and else. But switch and

When the example Visual Studio solution is run (typically with Ctrl-F5), two sites appear in the web browser. The vulnerable site sets a cookie, ostensibly containing sensitive data. The second site is the attacker, and it will collect the data from our evil request. The attacking site has a page that should read No victims yet. After we initiate our attack, it will display the secret cookie. On the vulnerable site, the cookie has been set with the code in listing 11.5, which is traditional cookie-setting code.

Figure 3-2. The site name and slogan are displayed as the page title and header. Default front page, as shown in Figure 3-3, determines the content displayed on the front page. The default node setting displays nodes in a list on the front page depending on the Number of posts on front page setting. With this set, all you need to do is select the check box promoted to front pag e when creating or editing a node for the node to appear on the front page. If you want a specific node to display as the homepage, simply enter node/nid, where nid equals the ID of the node. The number of posts on front page setting is the maximum number of nodes displayed on the homepage, including sticky content. This is covered in depth later in the section Setting up your front page.

case offer one useful advantage: they make it clear what we re doing we re looking at a single expression (raceStatus) and we re choosing one of a number of options based
