Hi Lorenz,
thanks for your reply, i tried it to change the dataProvider from OLEDB to SQLCLIENT in the plex runtime console. and now the console doesn't work and in the log file i got this message:
07/08/15 16:27:25 Type=2 [PLEX0016] Starting CA Plex .NET Runtime Console on port 1998.
07/08/15 16:27:26 Type=2 [PLEX0042] CA Plex .NET Runtime Console started.

07/08/15 16:27:35 Type=0 [PLEX9999] Nom d'objet 'ORDER_HEADER_FETCH' non valide. Client=127.0.0.1
But i stop my test about this sample. i will test now WFC services sample and web services.
