CommandBars Property [Excel 2003 VBA Language Reference]
Returns a CommandBars object that represents the Microsoft Excel command bars. Read-only.
Remarks
Used with the Application object, this property returns the set of built-in and custom command bars available to the application.
When a workbook is embedded in another application and activated by the user by double-clicking the workbook, using this property with a Workbook object returns the set of Microsoft Excel command bars available within the other application. At all other times, using this property with a Workbook object returns Nothing.
There is no programmatic way to return the set of command bars attached to a workbook.
Example
This example deletes all custom command bars that aren't visible.
For Each bar In Application.CommandBars
If Not bar.BuiltIn And Not bar.Visible Then bar.Delete
