can you make a password active after a certain date?

[RCollinge]

I dont know if this is at all possible??

I wanted to enable a spreadsheet to be password protected after a certain timeframe has passed - or on a specified date.

No idea where to start so any help or suggestions would be appreciated

Good morning RCollinge

This isn't possible using any native Excel commands but we could write our own using the Before_Save event procedure. The code below will happily let a workbook save without a password, however, after 1st Jan next year a password (of "password") will be added - with no warning - to the file when it is saved. However, there is a big but here. The user must say "OK" to run macros when the file is opened - if the user says no to the macro question the code will do nothing. And don't forget that this code (as it uses event procedures) needs to go into the ThisWorkbook pane of the VBE.

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
Application.DisplayAlerts = False
mydate = Now()
mydate2 = DateValue("January 1, 2006")
ActiveWorkbook.Save
If mydate > mydate2 Then
ActiveWorkbook.SaveAs Filename:="C:\Book4.xls", Password:="password"
End If
Application.DisplayAlerts = False
End Sub
