In contrast to external documentation, internal documentation is found within the program listing itself. It s the most detailed kind of documentation, at the sourcestatement level. Because it s most closely associated with the code, internal documentation is also the kind of documentation most likely to remain correct as the code is modified. The main contributor to code-level documentation isn t comments, but good programming style. Style includes good program structure, use of straightforward and easily understandable approaches, good variable names, good routine names, use of named constants instead of literals, clear layout, and minimization of control-flow and data-structure complexity. Here s a code fragment with poor style:

delegate void SomeDelegate<in T>(ref T t);

Be aware that doing so removes a security feature . Because a component of the Windows security system prevents any other application from capturing this particular key combination, pressing Ctrl+Alt+Delete ensures that the next screen that appears, the logon screen, is displayed by the operating system and not by a rogue application that s trying to capture your password, for example .

The MVC pattern originated with the Smalltalk programming language and provides a concise way to structure an application s user interface around three related components: The model contains an independent representation of the data your application visualizes. The view is responsible for rendering the contents of the model in a specific (such as a list or table) way. The controller takes events from the user and performs the appropriate actions (for example, scrolling or collapsing part of the view), forwarding the application-specific behavior for handling the event to either the model or view. MVC has been around long enough that there s a great deal written about it, and most GUI frameworks today support it. If you re unsure of how the pieces fit together after reading this section, take a look at Wikipedia or the Portland Pattern Repository at www.c2.com/cgi/wiki WelcomeVisitors.

The basic layout of the Windows Media Player interface hasn t changed much in the past five years, although its visual design is greatly streamlined compared to its predecessors. As Figure 15-1 shows, the Player window consists of six main elements (some of which may be hidden) when content is playing and Now Playing is selected:

In this chapter, I talk about callback functions. Callback functions are an extremely useful programming mechanism that has been around for years. The Microsoft .NET Framework exposes a callback function mechanism using delegates. Unlike callback mechanisms used in other platforms, such as unmanaged C++, delegates offer much more functionality. For example, delegates ensure that the callback method is type safe (in keeping with one of the most important goals of the common language runtime). Delegates also integrate the ability to call multiple methods serially and support the calling of static methods as well as instance methods.
