Internationalization is the act of preparing your plugin for use in any number of languages. WordPress uses U.S. English as its default language, but it has a large community of users who don’t read and write in English. This community pulls together to create translations of WordPress in languages used all around the world.

It would be quite easy to write an entire book about the sensors that you can use with Windows and still not cover them all. In fact, it would be possible to write a rather larger book just about the various sorts of industrial sensors. Home security would require an entirely separate book because the number and variety of sensors have increased so greatly. For example, many people don’t realize it, but there’s a special sort of sensor that can detect the sound of breaking glass and report it to you. If someone threw a rock through your window, you’d know about it long before you arrived home. Consequently, this chapter gives you just a taste of the sorts of things you can do in Windows 7 with various kinds of sensors.

How to Use ASP.NET 4 User Controls

User controls are great for encapsulating markup, controls, and code that you need repeatedly throughout your site. To some extent, they look a bit like server controls in that they can contain programming logic and presentation that you can reuse in your pages. However, rather than dragging existing ones from the VWD Toolbox, you need to create your own user controls and then add them to your ASPX pages, as you learn how to do later in this chapter.

Though master pages enable you to create content that is displayed in all pages in your site, it’s common to have content that should appear only on some but not all pages. For example, you may want to display a banner on a few popular pages, but not on the home page or other common pages. Without user controls, you would add the code for the banner (an image, a link, and so on) to each page that needs it. When you want to update the banner (if you want to use a new image or link), you need to make changes to all pages that use it. If you move the banner to a user control and use that control in your content pages instead, all you need to change is the user control, and the pages that use it pick up the change automatically. This gives you a flexible way to create reusable content.

How to Create Master Pages with ASP.NET 4

Master pages are added to the site using the Add New Item dialog box. They can be placed anywhere in the site, including the root folder, but from an organizational point of view, it’s often easier to store them in a separate folder. Just like normal ASPX pages, they support the inline code model as well as the Code Behind model. The master pages used in the Planet Wrox project use the Code Behind model exclusively. In the following exercise, you learn how to create a simple master page and add some HTML to it to define the general structure of the pages in your web site.
