This is one of the FAQs about Office Commandbars. For some reason, you may want to suppress the shortcut menus brought up by right-clicking the content of an Office document. This is an example of how to disable them in Word:
CustomizationContext = ActiveDocument Dim bar As CommandBar For Each bar In CommandBars If bar.Type = msoBarTypePopup Then bar.Enabled = False End If Next
With little modification, you should be able to do the same thing in Excel, PowerPoint and other Office applications that have the Office Commandbars collection.
