Thanks a lot for clarifying it, i tested it now it works for every date and
column.

comparing dates that way would be inaccurate. to illustarte from the
immediate window:

? "01/12/2005" < "03/01/1995"
True


Private Sub Workbook_Open()
Dim cell As Range
Worksheets("May_05").Activate
ActiveSheet.Unprotect Password:="mypass"
For Each cell In Rows(1).Cells
If cell.Value2 < clng(Date) - 1 Then
cell.EntireColumn.Locked = True
Else
cell.EntireColumn.Locked = False
End If
Next
ActiveSheet.Protect Password:="mypass"
End Sub

I have created a worksheet(May_05), in which i am trying to lock the
columns
based on date values, if the first row of the colums has a date lower
than
the current date the whole column should get locked, It works but only
sometimes. Following is the code i am using.

Private Sub Workbook_Open()
Dim cell As Range
Worksheets("May_05").Activate
ActiveSheet.Unprotect Password:="mypass"
For Each cell In Rows(1).Cells
If cell.Text < Format(Date - 1, "dd/mm/yyyy") Then
cell.EntireColumn.Locked = True
Else
cell.EntireColumn.Locked = False
End If
Next
ActiveSheet.Protect Password:="mypass"
End Sub

Please let me know if i am doing anything wrong or is there a better way
to
achieve the same. I am also attaching my workbook for the same.

Thanks for your help in advance.
