File.SetAttributes problem

Hi All,
I've modified a simple Aspnet program from a text to show file information,
including attributes and I keep getting an error which I cannot seem to
solve; here's the important parts:
Imports System
Imports System.IO
Imports System.IO.DirectoryInfo
Imports System.IO.File
Imports System.IO.FileAttributes
............
Private Sub PageLoad()
Dim f as new FileInfo("file path")............
'change file attributes to hidden or archive just for kix
'File.SetAttributes(path, FileAttributes.Archive)
'File.SetAttributes(path, FileAttributes.Hidden)
'f.Attributes = 2
'f.Attributes = FileAttributes.Hidden
'none of these work,
The program compiles fine, but kicks out on run with this error:
System.ArgumentException: Invalid File or Directory attributes value. When
the error lines above are commented out, the program runs fine. Any help is
much appreciated.
