Taking away the menu items and the paths to them might do it for you.
Place this in your workbook module and see if it accomplishes what you are after. To easily access your workbook module, find the little Excel workbook icon near the upper left corner of your workbook window, usually just to the left of the File menu option. Right click on that icon, left click on View Code, and paste the following procedure into the large white area that is the workbook module. Press Alt+Q to return to the worksheet.
Private Sub Workbook_Activate()
With Application
.CommandBars("Worksheet Menu Bar").Controls("Edit").Controls("Delete Sheet").Enabled = False
.CommandBars("Worksheet Menu Bar").Controls("Insert").Controls("Worksheet").Enabled = False
.CommandBars("Toolbar List").Enabled = False
.CommandBars("Ply").Enabled = False
End With
End Sub
Private Sub Workbook_Deactivate()
With Application
.CommandBars("Worksheet Menu Bar").Controls("Edit").Controls("Delete Sheet").Enabled = True
.CommandBars("Worksheet Menu Bar").Controls("Insert").Controls("Worksheet").Enabled = True
.CommandBars("Toolbar List").Enabled = True
.CommandBars("Ply").Enabled = True
End With
End Sub
Save the workbook, then either
- close it and re-open it
or
- activate another Excel workbook (open in that instance of Excel) and re-activate the subject workbook
