You can stop the users from getting to Tools|options with code like:
Option Explicit
Private Sub Workbook_Activate()
Dim myID As Long
myID = 522 '&Options...
Call EnableDisableByID(myID, False)
End Sub
Private Sub Workbook_Deactivate()
Dim myID As Long
myID = 522 '&Options...
Call EnableDisableByID(myID, True)
End Sub
Sub EnableDisableByID(myID As Long, TurnOn As Boolean)
Dim myCommandBar As CommandBar
Dim myCtrl As CommandBarControl
For Each myCommandBar In Application.CommandBars
Set myCtrl = myCommandBar.FindControl(ID:=myID, recursive:=True)
If myCtrl Is Nothing Then
'do nothing
Else
myCtrl.Enabled = TurnOn
End If
Next myCommandBar
End Sub
You can plop all 3 subs right into the ThisWorkbook module. (The last one could
go into a general module, instead.)
But personally, I think won't stop any user who can find the newsgroups.
