read-only access

Hai,

I'm using the functions below to find some directory in which a user has write access. However, in a map with 50 subdirectories where the user only has write access to 5 of them I find the procedure to slow.

Does someone know a quicker way to check for write access to the sub maps?

(BTW, yes, most of the functions came out of VBA help files  ;-)   )

Function Make_List() As String
Dim MyPath As String, MyName As String, maplist As String
  MyPath = "f:\data\"
  MyName = Dir(MyPath, vbDirectory)
  Do While MyName <> ""
    If MyName <> "." And MyName <> ".." Then
      If (GetAttr(MyPath & MyName) And vbDirectory) = vbDirectory Then
            If check_access(MyPath & MyName & "\") Then maplist = maplist & "," & MyName
      End If
    End If
    MyName = Dir
  Loop
  Make_List = Right(maplist, Len(maplist) - 1)
End Function

Private Function check_access(pad As String) As Boolean
  On Error GoTo handler
  Open pad & "TESTFILE" For Output As #1
  Close #1
  Kill pad & "TESTFILE"
  check_access = True
  Exit Function
handler:
  check_access = False
End Function

Kind regards
