I'm not sure how False fits in (maybe you meant "bad user"??)

But maybe you could debug your code by adding a line and seeing what the VBE
immediate window shows:

Option Explicit
Private Sub Workbook_Open()
Dim res As Variant
Dim Arr As Variant
Arr = Array("Guest", "Jim", "Bob", "Norman")
Debug.Print "***" & Environ("UserName") & "***"
res = Application.Match(Environ("UserName"), Arr, 0)
If IsError(res) Then
MsgBox "GOOD user"
Else
MsgBox "BAD user"
End If
End Sub

If the problem is that you're not getting any message when you open the
workbook, make sure you enable macros for this workbook when/if you're prompted.

And this workbook_open procedure goes behind ThisWorkbook.

Small Update:

I am aware that Environ("UserName") applies to the WWindows Logon and
Application:USerName for the Username in the Excel application ....

Nevertheless Environ("UserName") should return False ...as my Windows Logon
is nor Guest, Jim, Bob or Norman ...

Any thoughts?

Hi There,

I want to test whether the person who wants to open a file is entitled to
it or not ...
I am testing it with the Username in Excel versus an array with Usernames.
The problem is that my code says always that it is a "good user"... even
if the username under ToolsOptionsGeneral is "dfhdgkj"!

Any insight on where I am missing the ball?

Somewhere on the NG I found the code from Norman Jones, so 99% of the
credit goes to him ... the 1% I changed made it work not properly though
;)
Private Sub Workbook_Open()
Dim s As Integer
Dim vh As Integer

Arr = VBA.Array("Guest", "Jim", "Bob", "Norman")
Res = Application.Match(Environ("UserName"), Arr, 0)
If IsError(Res) Then
MsgBox "GOOD user"

Else
MsgBox "BAD user"
End If
End Sub

Thanks for your help!
Jen
