Conventions Used in This Book
The following typographical conventions are used in this book:
Constant width
Indicates text you??™re supposed to type, output from a command-line
program, code examples, Registry keys, and paths to Registry keys.
Constant width italic
Indicates user-defined elements within constant-width text (such as filenames
or command-line parameters). For example, Chapter 8 discusses
a file encryption utility, cipher.exe, which has a variety of command-line
options. A particular solution might instruct you to type:
cipher /r:filename
The italicized portion of this code, filename, signifies the element you??™ll
need to replace with whatever is applicable to your system or needs. The
rest??”the non-italicized portion??”should be typed exactly as shown.
Bold
Identifies captions, menus, buttons, checkboxes, tabs, keyboard keys,
drop-down lists and list options, and other interface elements. Bolding
interface elements makes it easy to distinguish them from the rest of the
text.
