Hello Chaos
I have the same issue with a roster that relies on validation which can easily be wrecked by copy/cut/paste drag and fill. I got this code from somewhere a few years back which you copy into the VBA Module ThisWorkbook to work. It's pretty tight I find and only allows manual entry - no drag or drop or anything. If you need to do some copying and pasting again you have to simply delete it from the module and copy back when you are finished. Apologies to who ever out there wrote this brilliant code.
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
Good luck
John
