Hola, te muestro una forma con la que yo accedia a baces de datos Acces.

Dim Cn as New ADODB.Connection
Dim Rs as New ADODB.Recordset
Dim SQL as String

Private Sub Fom_Load ()

SQL= "SELECT nombre, direccion, tel, Empresa, num_tran " _
& "FROM Clientes; "
cn.Open "DSN=Nomb_Archivo.mdb"
rs.CursorType = adOpenStatic
rs.LockType = adLockBatchOptimistic
rs.Open SQL, cn, , adLockBatchOptimistic

If Rs.EOF = False Then
Rs.MoveFirst
ActualizarDatos
end if
End Sub

Private Sub Command1_click 'Mover adelante
If rs.BOF = True And rs.EOF = False Then
rs.MoveNext
ActualizarDatos
End If
End Sub

Private Sub Command2_click 'Mover atras
If rs.BOF = True And rs.EOF = False Then
Rs.MovePrevius
ActualizarDatos
end if
End Sub

Private Sub Command3_click 'Mover Ultimo
If rs.BOF = True And rs.EOF = False Then
Rs.MoveLast
ActualizarDatos
end if
End Sub

Private Sub Command4_click 'Mover Primero
If rs.BOF = True And rs.EOF = False Then
Rs.MoveFirst
ActualizarDatos
end if
End Sub

Private Sub Fom_UnLoad ()
Rs.close
cn.close
Set Rs = Nothing
End Sub

Public Sub ActualizarDatos
txt(0).DataField = Rs.Fields("nombre") .value
txt(1).DataField = Rs.Fields("direccion").value
txt(2).DataField = Rs.Fields(2).value 'Tel
txt(3).DataField = Rs.Fields(3).value 'Empresa
txt(4).DataField = Rs.Fields(4).value 'num_tran
End Sub

No lo probe puedo tener algunos errores de sintaxis, de reconosimiento inmediatos, desde VB. En este momento no tengo VB para provarlo.
Espero haberte ayudado.
