Occurs when any change is made to a command bar.
Syntax
Private Sub CommandBars_OnUpdate()
Remarks
The OnUpdate event is recognized by the CommandBar object and all command bar controls. The event is triggered by any change to a command bar or command bar control or any change to the state of a command bar or command bar control. These changes can occur due to a text or cell selection, for example. Since a large number of OnUpdate events can occur during normal uage, developers should exercise caution when using this event. It is strongly recommended that this event be used primarily for checking that a custom command bar has been added or removed by a COMAddIn. For more information on using events with COM add ins, see the chapter "Add-ins, Templates, Wizards, and Libraries" in the Microsoft Office 2000/Visual Basic Programmer's Guide.
