Figure 5-1. Silverlight s built-in fonts In the case of Lucida, there are two variants with slightly different names. Lucida Sans Unicode is included with Windows, while Lucida Grande is an almost identical font that s included with Mac OS X. To allow this system to work, the FontFamily property supports font fallback in other words, you can supply a comma-separated list of font names, and Silverlight will used the first supported font. The default TextBlock font is equivalent to setting the FontFamily property to the string Lucida Sans Unicode, Lucida Grande. You might think that you can use more specialized fonts, which may or may not be present on the client s computer. However, Silverlight doesn t allow this. If you specify a font that isn t one of the nine built-in fonts, and it isn t included with your application assembly (more on that in the next section), your font setting will be ignored. This happens regardless of whether the client has an installed font with the appropriate name. This makes sense after all, using a font that s only supported on some systems could lead to an application that s mangled or completely unreadable on others, which is an easy mistake to make.

Sub Session_End(ByVal sender As Object, ByVal e As EventArgs) End Sub </script> Looks can be deceiving, however. At runtime, the code within this <script> block is assembled into a class type deriving from System.Web.HttpApplication. If you have a background in ASP .NET 1.x, you may recall that the Global.asax code-behind file literally did define a class deriving from HttpApplication. As mentioned, the members defined inside Global.asax are in event handlers that allow you to interact with application-level (and session-level) events. Table 27-1 documents the role of each member.

Figure 1-4. Flowchart for example with one entry and one exit The single-entry/single-exit model makes the logic easier to follow, which in turn makes the code easier to manage. This rule also applies to looping structures, which you implement via the WHILE statement in T-SQL. Avoid using the WHILE loop s CONTINUE and BREAK statements and the GOTO statement; these statements lead to old-fashioned, difficult-to-maintain spaghetti code.

If you want to use non-standard fonts in your application, you can embed them in your application assembly. That way, your application never has a problem finding the font you want to use. The embedding process is simple. First, you add the font file (typically, a file with the extension .ttf) to your application and set the Build Action to Resource. You can do this in Visual Studio by selecting the font file in the Solution Explorer and changing its Build Action in the Properties page. Next, when you set the FontFamily property, you need to use this format: FontFileName#FontName For example, if you have a font file named BayernFont.ttf, and it includes a font named Bayern, you would use markup like this: <TextBlock FontFamily="BayernFont.ttf#Bayern">This is an embedded font</TextBlock> Figure 5-2 shows the result.

One of the powerful features available to SQL Server 2008 is its ability to execute .NET Framework based code via the SQL Common Language Runtime (SQL CLR). You can use standard .NET Framework classes to access XML-based functionality that is not supported directly within T-SQL. One useful feature that can be accessed via SQL CLR is the W3C Extensible Stylesheet Language Transformations (XSLT). As defined by the W3C, XSLT is a language designed for the sole purpose of transforming XML documents into other XML documents. SQL Server 2008 provides access to XSL transformations via a combination of the built-in xml data type and the .NET Framework XslCompiledTransform class.
