Question : How to determine if a user is logged in through Citrix

I deploy Access 2003 applications that have been packaged using Microsoft Access 2003 developer extensions.  One of these applications needs to run different startup code if the user is logged in through Citrix.  Currently I am determining whether the user is logged in through Citrix using the code shown below.  Basically it reads through the environ variables and loads them into a table.  It then queries the table to see if there is a variable containing "CLIENTNAME".  If there is, then the user is logged in through Citrix.
This code does the job but I was just wondering if anyone knows of a more "elegant" way of determing if the user is logged in through Citrix using VBA.

    Dim EnvString As String
    Dim rs As DAO.Recordset
    Dim Indx As Long
   
    DoCmd.OpenQuery "Clear Environ Variables"
   
    Indx = 1
   
    Set rs = CurrentDb.OpenRecordset("Environ Variables")
    Do
        EnvString = Environ(Indx)
        If Len(Trim(EnvString)) > 250 Then
            rs.AddNew
            rs!variablename = Left(EnvString, 250)
            rs.update
        Else
            rs.AddNew
            rs!variablename = EnvString
            rs.update
        End If
        Indx = Indx + 1
    Loop Until EnvString = ""
   
    rs.Close
   
    If DCount("*", "Check for CLIENTNAME") > 0 Then
        CitrixYN = "Y"
    Else
        CitrixYN = "N"
    End If

Answer : How to determine if a user is logged in through Citrix

I was looking for something other than using the Environ variables to determine if user was logged on through Citrix.  I guess I'll assume it's the only way.
