Trying to retrieve an array stored in a VFP MEMO field using a VFP SP via VFPOLEDB.

The SP looks like this:

PROCEDURE GetShortNutri
LPARAMETERS theFile, theField, theRecno
USE &theFile. ORDER Id
=SEEK(theRecno)
RESTORE FROM MEMO &theField.
CREATE CURSOR result (Val1 N(5), Val2 N(5))
APPEND FROM ARRAY pgndata 
SETRESULTSET('result')
RETURN RECCOUNT('result')
ENDPROC

The C# code:

using (OleDbConnection conn = new OleDbConnection(this.ConnectionString))
            {
                DataSet ds = new DataSet();

                string commandString = "GetShortNutri('" + this.TableName + "','" + this.FieldName + "'," + this.Record + ")";
                conn.Open();
                OleDbCommand command = new OleDbCommand(commandString, conn);
                command.CommandType = CommandType.StoredProcedure;
                var adapter = new OleDbDataAdapter(command);
                adapter.Fill(ds);  //Exception: 'Feature not available'
            }

SP works in VFP. All parameters are correct in the C# code (TableName and FieldName are strings; Record is int) . But 'adapter.Fills(ds)' throws the commented exception. Any suggestions ?

Oh, and I tried substituting ' (theField) ' instead of ' &theField ' etc. same thing....
