Can't update a Access 2002 form's ado recordset through odbc

[RAPPAZ Francois]

According to Miscrosoft docs at http://support.microsoft.com/kb/281998/EN-US/, it seems
that a form's ado recordset with access 2002 should be updatable using ODBC. 

However, with a form in a mdb file with the access 2002 format, I still have the
"recordset is not updatable"  message ... Is there anyone who have managed this ?

I use mysql and Connector/ODBC 3.51.

I tried the following code on AfterUpdate of a text control: sSearch is a string with the
words being searched for.

Dim Cn As New ADODB.Connection
Dim rec As New ADODB.Recordset
Dim  strConnection As String, sql as String

strConnection =
"ODBC;DSN=mysql_dokpe_i01_adm;UID= ... ;PWD= ... ;DATABASE=dokpe_i01"
     With Cn
      .Provider = "MSDASQL"
      .Properties("Data Source").Value = strConnection
      .Open
   End With

    sql = "select concat(nofm, '') as nofm, ti, tri, issn, ex, ad,
concat(noed,'') as noed, dom from jrn where match(ti) against(" &
Chr(39) & sSearch & Chr(39) & " in boolean mode)"
    rec.CursorLocation = adUseClient
    rec.Open sql, Cn, adOpenKeyset, adLockOptimistic

    If Not rec.EOF Then

        Set Me.Recordset = rec

    Else
        MsgBox "No data"
    End If
End If
Set rec = Nothing
Set Cn = Nothing
