Disable copy paste

The following code was previously posted to disable copy/paste.

It includes a message box to notify the user that right click has been disabled.

I would like to know how to add code to include a message box to notify the user that cut/copy has been disabled when the shortcut keys (control x/control c) are used.

Thank you in advance for any assistance!

Private Sub Workbook_Activate()
Application.CutCopyMode = False
Application.OnKey "^c", ""
Application.CellDragAndDrop = False
End Sub

Private Sub Workbook_Deactivate()
Application.CellDragAndDrop = True
Application.OnKey "^c"
Application.CutCopyMode = False
End Sub

Private Sub Workbook_WindowActivate(ByVal Wn As Window)
Application.CutCopyMode = False
Application.OnKey "^c", ""
Application.CellDragAndDrop = False
End Sub

Private Sub Workbook_WindowDeactivate(ByVal Wn As Window)
Application.CellDragAndDrop = True
Application.OnKey "^c"
Application.CutCopyMode = False
End Sub

Private Sub Workbook_SheetBeforeRightClick(ByVal Sh As Object, ByVal Target As Range, Cancel As Boolean)
Cancel = True
MsgBox "Right click menu deactivated." & vbCrLf & _
"Cannot copy or ''drag & drop''.", 16, "For this workbook:"
End Sub

Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)
Application.CutCopyMode = False
End Sub

Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Application.OnKey "^c", ""
Application.CellDragAndDrop = False
Application.CutCopyMode = False
End Sub

Private Sub Workbook_SheetDeactivate(ByVal Sh As Object)
Application.CutCopyMode = False
End Sub
