You could do something like

Private Sub Workbook_Open()
If Date > DateValue("12-Mar-2006") Then
MsgBox "Cannot open - expired"
ThisWorkbook.Close savechanges:=False
End If
End Sub

'This is workbook event code.
'To input this code, right click on the Excel icon on the worksheet
'(or next to the File menu if you maximise your workbooks),
'select View Code from the menu, and paste the code

but a user can circumvent it by just disabling macros.

Hi Vikky

Workbook_open, and other workbook related events, goes in the ThisWorkbook
module, no in sheets' modules.

Hi;

One more Question;

I've made a file with n No. of formulas.
Can we disable the formula function after a particuler date.

Thanks.

You can make your formulas check the date
=IF(TODAY()<DATE(2006,8,8),SUM(A1:A100),"too late")
or you can create a macro that destroys stuff if the date is later than some
day.

But what you really ask is "can Excel protect my work" and the answer is no
way. You can keep unskilled users away from your secrets, but that's about
it. Excel protection is to protect against accidents, not to protect
content.

HTH. Best wishes Harald
