Rules at a Glance

• prompt can contain approximately 1,000 characters, including carriage return characters such as the built-in vbCrLf constant.

• If the title parameter is omitted, the name of the current application or project is displayed in the title bar.

• If you omit the buttons argument, the default value is 0; that is, VB opens an application modal dialog box containing only an OK button.

• The constants of the MsgBoxStyle enumeration can be added together to form a complete buttons argument. The constants can be divided into the following groups:

  Button Display Constants

  Icon Display Constants

  Default Button Constants

  Modality Constants

• Only one constant from each group can be used to make up the overall buttons value.
