Peter B,
I take it that your previous post from anonymous didn't get answered
and that you're the same person????
Anyway...to answer your question(s)...
Is there a way to secure a worksheet
Yes and no.......
Depends on who you're trying to "secure" it from???
Somebody that doesn't know Excel at all?? Probably
Somebody with experience in Excel (or access to this ng or Google)??
Not a chance.....
Okay...enough of the disclaimers......
In a regular module (Alt+ F11, right click on "ThisWorkbook,
select "Insert" and then "Module").
Copy and paste the following:
Sub Auto_Open()
Application.OnTime Now + TimeValue("00:01:00"), "StopMe"
End Sub
Sub StopMe()
ThisWorkbook.Save
ThisWorkbook.ChangeFileAccess xlReadOnly
End Sub
The above will start a 1 hour timer when the workbook opens.
After an hour, it will call the StopMe sub.
That sub will save the workbook (optional) and change the
file access to ReadOnly
