Windows messagebox

The message box contains three push buttons: Yes , No , and Cancel. An icon consisting of a lowercase letter i in a circle appears in the message box. A question-mark icon appears in the message box.

The question-mark message icon is no longer recommended because it does not clearly represent a specific type of message and because the phrasing of a message as a question could apply to any message type. In addition, users can confuse the message symbol question mark with Help information. Therefore, do not use this question mark message symbol in your message boxes.

A message box is a prefabricated modal dialog box that displays a text message to a user. You show a message box by calling the static Show method of the MessageBox class. The text message that is displayed is the string argument that you pass to Show. Several overloads of the Show method also enables you to provide a title bar caption. To enable a user to close a message box, Show displays a message box that has an OK button and a Close button in the title bar.

You can also use a message box to ask a user a question. The user answers by clicking one of several buttons that you specify to display by using the MessageBoxButton enumeration. You can pass this enumeration to several overloads of the Show method.

You can determine which button a user clicks by examining the value that Show returns. The return value is a value of the MessageBoxResult enumeration, where each value equates to one of the buttons that a message box can display. The default value for message box is OK because OK is the default message box button. However, some overloads of the Show method enable you to provide a different MessageBoxResult default value.

The MessageBoxImage enumeration encapsulates the set of possible message box icons. By default, a message box does not display an icon. However, you can pass a MessageBoxImage value to one of several Show method overloads in order to specify that the message box includes an icon.

Message boxes sometimes provide special functionality, such as right-to-left reading. You can customize the behavior of a message box by using one or more MessageBoxOptions enumeration values that are accepted by some overloads of the Show method. Message boxes always have an owner window.
