ADO Error

[mik706]

When I run this script I get the error: Rowset does not support fetching backward.

This error occurs when I try to use the Rst.MoveLast command but I was under the impression that I could do this if I had opened the record set as "Rst.CursorType = adOpenDynamic" obviously I am doing something wrong here can someone point me in the right direction please.

Dim CN As New ADODB.Connection
Dim Cmd As New ADODB.Command
Dim Rst As New ADODB.Recordset
Dim DeviceCount As Integer
Dim Count As Integer
 
'Open DB Connection
CN.Open DBPath
 
Set Rst = New ADODB.Recordset
Rst.CursorType = adOpenDynamic
Rst.Supports (adMovePrevious)
 
 
'Prepare the user-defined function statement and execute the command.
Cmd.ActiveConnection = CN
Cmd.CommandText = "SELECT DeviceName, DeviceType, CMACNum, Address, PLCID, NumEvents, StartRead, StopRead FROM SOEWFC_Definitions;"
Set Rst = Cmd.Execute
 
    
'Check to see if there are any records in the table
If Rst.EOF = False Then
    'get number of rows in Backups table
    Rst.MoveLast
    DeviceCount = Rst.RecordCount
    Rst.MoveFirst
End If
