Dialog boxes appear when Windows XP needs information from you to execute a command. In a word processing program, for example, a dialog box appears when you choose the Print command. To print a document, you use the dialog box to specify which printer to use, which pages to print, and how many copies to print. In some dialog boxes, default choices are already filled in for you and you simply need to confirm these selections.
Parts of typical dialog boxes are shown in Figure M2-16 and Figure M2-17. Windows XP dialog boxes incorporate easy-to-use features that allow you to select the options you want to use. The parts of a dialog box and their uses are described in Table M2-5.
