    I want to change the int variable:MIdNum, which i defined in my model from .det application
    The followings are my .dat code and .net code:
    -----------.dat code:----------------------
    DBConnection db("access","oilDB.mdb");
    Gasolines,Gas from DBRead(db,"SELECT name,name,demand,price,octane,lead FROM GasData where Id = ?")(MIdNum);
    -----------.det code:----------------------
    OplModel opl = oplF.CreateOplModel(def,cplex);
    OplDataElements dataElements = oplF.CreateOplDataElements();
    dataElements.AddElement(dataElements.MakeElement("MIdNum", 2));
    opl.AddDataSource(dataElements);
    OplDataSource dataSource = oplF.CreateOplDataSource(System.Environment.CurrentDirectory + @"\oilDB2.dat");
    opl.AddDataSource(dataSource);
    opl.Generate();
    but i always failed.
