Ho provato a inserire questo semplicissimo script il codice dovrebbe essere corretto e mi dà lo stesso errore.

Ecco il codice

<%@ Language="VB" debug="true" %>
<%@ Import NameSpace="System.Data" %>
<%@ Import NameSpace="System.Data.OleDb" %>
<script language="VB" runat="server">
Sub InserisciNome(obj as object, e as eventargs)
'Ora devo effettuare l'inserimento
'per prima cosa creo la connessione
dim Conn as new OleDbConnection ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Inetpub\wwwroot\aspnet\michele\mdb-database\prova.mdb")
dim sqlstring as string = "insert into utenti (nome) values ('" & nome.text & "') "
'ora devo eseguire il comando
dim objCmd as new OleDbCommand
objCmd.Connection = Conn
objCmd.CommandText = sqlstring
objCmd.Connection.Open()
objCmd.ExecuteNonquery()
objCmd.Connection.Close()
End Sub
</script>

</form>
</body>
</html>

Ed ecco il solito errore

Datemi una mano per piacere non so più cosa fare , questo errore si verifica anche quando effettuo un update oppure un delete
