Change Data Link Properties programmatically

Is it possible to change the data link properties or the connection string for a .adp when the file is opened?

I would like to user NT integrated security in one location and a SQL server user account in another.

Many thanks

I use the sample code below.

Function ChangeADPConnection(strServerName As String, strDBName As String, Optional strUN As String, Optional strPW As String) As Boolean
Dim strConnect As String
On Error GoTo EH:
'The Provider, Data Source, and Initial Catalog arguments are required.
strConnect = "Provider=SQLOLEDB.1;Data Source=" & strServerName & ";Initial Catalog=" & strDBName
If strUN <> "" Then
    strConnect = strConnect & ";user id=" & strUN
    If strPW <> "" Then strPW = Chr(34) & Chr(34)
    strConnect = strConnect & ";password=" & strPW
Else  'Try to use integrated security if no username is supplied.
    strConnect = strConnect & ";integrated security=SSPI"
End If
Application.CurrentProject.OpenConnection strConnect
ChangeADPConnection = True
Exit Function
MsgBox Err.Number & ": " & Err.Description, vbCritical, "Connection Error"
ChangeADPConnection = False
End Function
