With help from this group, I am using the following code to hide empty
columns in my spreadsheet. It works when my sheet is not protected,
however, when I deploy this sheet for use by others it will need to be
password-protected. What can I add to the code to unprotect the sheet
prior to hiding the columns and then re-protect the sheet after the
columns have been hidden? Will my password-protection be preserved?
Please help...

Sub Hide_EmptyColumns()
'To hide columns with no data in rows 10:82


Application.ScreenUpdating = False
With Sheets("Box")
Dim col As Range
For Each col In .Range("C10:AF82").Columns
col.EntireColumn.Hidden = _
Application.Sum(col) = 0

Next
End With
Application.ScreenUpdating = True
End Sub
