When the backup commences, a checkpoint is issued that flushes dirty buffer cache pages to disk. After the checkpoint completes, the backup process begins reading pages from the database for inclusion in the backup file(s), including page X. Transaction A begins. Transaction A modifies page X. The backup has already included page X in the backup file, so this page is now out of date in the backup file. Transaction B begins, but won t complete until after the backup finishes. At the point of backup completion, this transaction is the oldest active (uncommitted/incomplete) transaction.

Here s the result:

Launch Project Builder. Create a new Cocoa project by selecting File New Project and choosing Cocoa Application from the project list. Click the Next button, save the project as InterfaceBuilderExample, and click the Finish button. Expand the Resource folder and double-click on MainMenu.nib. Doing so launches Interface Builder and loads the Nib file.

Based on my experience, however, many organizations shy away from designing homegrown solutions as WinForm applications. Instead, they usually opt for web-based designs. Why is that, considering all the advantages that the rich client model has to offer There are a few good reasons, but the top one I hear is the difficult deployment model. WinForm applications usually have binary dependencies to other system or third-party libraries. For this reason, they need to be explicitly installed on the client machine. In the past, this has led to many problems, including the notorious DLL Hell phenomenon, where a rogue installation program replaces system files, which in turn, causes one or more existing applications to stop working. To further complicate the matter, after the application is rolled out to the end users, some infrastructure has to be set up to handle the application updates, such as bug fixes and new versions. The Microsoft .NET Framework introduces several new features aimed at simplifying the WinForm application deployment, such as web-based deployment, versioning, and side-by-side execution. Expect these features to improve in the next versions of Windows and .NET. For example, the forthcoming release of Visual Studio .NET, code-named Whidbey, will feature the ClickOnce deployment model. It will allow us to create rich clients that can automatically update themselves from a central web location. For this reason, I predict that the pendulum will start swinging back in the near future and the rich client will take the place it deserves. 10.1.1 Report-enabling rich clients Let s now see how what we learned in chapter 9 applies to report-enabling WinForm clients. As you would recall, in chapter 9 we said that RS offers two options for requesting

Figure 14 7 shows an example matchmaking view, waiting for you to invite a friend to your match. You can also wait until Game Center finds an automatically matched player for your game, but since you re currently developing the game, it s rather unlikely that anyone but you will be currently playing it. If you followed the leaderboard and achievement view examples, you ll know that each required the GameKitHelper class to implement a protocol, and with matchmaking it s no different. I also added GKMatchDelegate because we re going to need it soon.

The result is a list of three integer values, representing the red, green, and blue values of an RGB color. Each number is from 65,535, which corresponds with the bright, full presence of the color, to 0, which means the color is dimmed all the way. For example, this result was returned after specifying a reddish color: {60790, 5233, 6667}. Notice that the first value, indicating the red value, is almost at the full brightness of 65,535, and the green and blue are relatively close to 0. The value of pure red will be {65535, 0, 0}. Although the color picker the users are presented with allows them to specify hex colors for web colors and CMYK colors, the result will always be the RGB color equivalent.

In this case, the compiler must determine dynamically whether the class implements IDisposable. The foreach expands to the following: IEnumerator e = container.GetEnumerator(); try { while (e.MoveNext()) { Resource r = e.Current; ...; } } finally { IDisposable d = e as IDisposable; if (d != null) d.Dispose(); }

Function pointers give you a new way to call a function. Function pointers allow you to say, Execute the function pointed to by this variable. Here s an example:

First let s look back at the basics. Everything in PowerShell is an object (even scripts and functions as we ll see later on). As discussed in chapter 1, objects have properties (data) and methods (code). To get at both, you use the dot . operator. To get the length of a string, you use the length property:

Keep in mind that the columns in the grid may not appear in the order you expect. The GridView control relies on reflection to get the properties of the objects it should display. This technique does not ensure that the properties are returned in the same order as they are declared in the bound object.

The /r:helloservicest.exe compiler option references the service assembly where the HelloObj type resides. This means that the remote server assembly must be available to the client at compile time. This won t always be possible. We ll look at alternative solutions to this problem later in the chapter. Note the greetings returned from the remote object each time we invoked the client. Now return to the first command window and view the output from the server shown in figure 5.4.
