Document.CustomToolbarsFile Property (Visio)
Published: July 16, 2012
Returns or sets the name of the file that defines custom toolbars and status bars for a Document object. Read/write.
Starting with Microsoft Visio 2010, the Microsoft Office Fluent user interface (UI) replaces the previous system of layered menus, toolbars, and task panes. VBA objects and members that you used to customize the user interface in previous versions of Visio are still available in Visio 2013, but they function differently.
If the object is not using custom toolbars, the CustomToolbarsFile property returns Nothing.
