In this chapter, you learned how to build a Web browser; in the process, you did the following: You added more than one control to the designer surface. You set properties in the Properties window. You wired an event to a control and learned how to add code that will execute when the event is triggered. In this example, you saw many OOP concepts in action by using only one line of code. You added the code to respond to the button click event by calling the Navigate method of your Web browser object. Your Web browser navigated to a URL passed in as an argument to the Navigate method. The argument for the Navigate method was passed in using the text box control s Text property. Everything was completed and fully working just by tweaking some properties and adding only one line of code! That s what I call productivity. In the next chapter, you ll continue this process by learning more about the major features of Visual C# 2008 Express Edition. You ll become more productive at developing applications by learning about features such as IntelliSense, snap lines, code snippets, Smart Tags, refactoring, and much more.

In addition to manually synchronizing when logging on and when logging off, you can specify other synchronization options using the Synchronization Manager, which you can open by choosing Start, All Programs, Accessories, Synchronize. In the Items To Synchronize dialog box, you can configure synchronization when the computer is idle, according to a schedule, or immediately. The following steps show you how to select these options.

A cluster (or allocation unit) is the smallest amount of disk space that can be allocated to hold a file. All file systems used by Windows XP Professional organize hard disks based on cluster size, which is determined by the number of sectors that the cluster contains. For example, on a disk that uses 512-byte sectors, a 512-byte cluster contains one sector, whereas a 4-KB cluster contains eight sectors. FAT16, FAT32, and NTFS each use different cluster sizes depending on the size of the volume, and each file system has a maximum number of clusters it can support. The smaller the cluster size, the more efficiently a disk stores information because unused space within a cluster cannot be used by other files. And the more clusters that are supported, the larger the volumes you can create and format by using a particular file system. Table 13-4 provides a comparison of FAT16, FAT32, and NTFS volume and default cluster sizes.

* Windows XP Professional formats FAT32 volumes up to 32 GB regardless of cluster size. To format volumes larger than 32 GB, you must use NTFS. However, Windows XP Professional can mount FAT32 volumes larger than 32 GB that were created by other operating systems.

manually synchronize immediately, click the Synchronize button. If you want to configure how synchronization occurs, click the Setup button.

In the Disk Management snap-in, you can specify a cluster size of up to 64 KB when you format a volume. If you use the format command to format a volume but do not specify a cluster
