Figure 5-8 gives you a glimpse of the Visual C# code snippets. All code snippets are made with customizable fields, which means they contain fields that are replaceable with code elements from your own applications. Going forward, you will be able to download additional code snippets from various sources such as the MSDN Web site, online communities, and other .NET vendors. You will also be able to add your own code snippets to the code snippets library to fulfill your needs in other projects.

File names in Windows XP Professional can be up to 255 characters and can contain spaces, multiple periods, and special characters that are not allowed in MS-DOS file names. Windows XP Professional makes it possible for other operating systems to access files that have long names by generating an MS-DOS-readable (8.3) name for each file. These MS-DOS-readable names also enable MS-DOS-based and Windows 3.x based applications to recognize and load files that have long file names. When a program saves a file on a computer running Windows XP Professional, both the 8.3 file name and long file name are retained. Note

computer s public DNS name or IP address to connect. See Using Remote Desktop over the Internet/Firewall, page 477, for more information.

The 8.3 format means that files can have between 1 and 8 characters in the file name. The name must start with a letter or a number and can contain any characters except the following: . / \ [ ] : ; | = , * (space) An 8.3 file name typically has a file name extension that is from one to three characters long and has the same character restrictions. A period separates the file name from the file name extension. Several special file names are reserved by the system and cannot be used for files or folders: CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL

To see both the long and short file names for each file in the folder, at the command line, type dir /x.

At the command prompt, if you type the long name of a file or folder that contains spaces, you must enclose the name in quotation marks. For example, if you have a program called Dump Disk Files and you enter the name without quotation marks at the command line, you will see the error message Cannot find the program Dump or one of its components. You must also use quotation marks around each referenced set of long file names when a path typed at the command line includes spaces, as in the following example: move c:\This month s reports\*.* c:\Last month s reports
