Inquiry dialog boxes

Use inquiry dialog boxes when users must confirm an action before continuing. A question mark (?) indicator appears in an inquiry

dialog box.

Best practice: Implementing inquiry dialog boxes

• Use a concise, descriptive question for the message.

• Always prompt users with an inquiry dialog box to save their changes when they attempt to close a screen with unsaved

changes.

• Include a Cancel button so that users can close the dialog box without making changes.

• Use verbs for labels that describe the associated action (for example, "Cancel," "Delete," "Discard," or "Save"). If necessary,

include more descriptive text elsewhere on the screen (for example, in an application message).

• Avoid using the labels "Yes" and "No."

Reminder dialog boxes

Use reminder dialog boxes to remind users of time-sensitive activities such as appointments or tasks.

Include a Snooze button that users can click to receive another reminder at a later time and a Dismiss button to dismiss the

reminder. To dismiss the reminder, users press the Escape key. To close a reminder dialog box, users click a button or press the

Escape key. Reminder dialog boxes include an indicator that represents the application that generated the reminder.
