When opening a form in Microsoft Access 2010 that is part of a database that was created in an earlier version of Microsoft Access, the specified toolbar will be displayed differently depending on the current settings of the
AllowFullMenus and
AllowBuiltInToolbars properties. If the
AllowFullMenus and
AllowBuiltInToolbars properties are set to False, the specified toolbar will replace the ribbon as the default set of commands available to the user. If the
AllowFullMenus or
AllowBuiltInToolbars property is set to
True, then the specified toolbar is displayed on the ribbon
Add-Ins tab.
