[Noob] Is it possible to protect the Re-open function?

[igorcdm]

When I try to protect a table with a password, I can't impede the user to re-open hidden columns. How do I block the Re-open function?

or if you like with a VBA solution, after you lock desired cells

Private Sub Worksheet_Activate()
Dim strPassword As String
strPassword = InputBox("Give you Passwort:")

On Error GoTo Falsch
Me.Unprotect strPassword
Me.Protect strPassword
On Error GoTo 0
Exit Sub
Falsch:
MsgBox "Wrong Passwort"
Worksheets("Name it").Activate
End Sub

If you have after that a question, will be happy to answer/help.
