    {
        OleDbConnection sqlcon;
        string strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data source=" + Server.MapPath("vs.mdb");
        sqlcon = new OleDbConnection(strCon);
        string sqlstr = "select * from newl";
       OleDbDataAdapter myda = new OleDbDataAdapter(sqlstr, sqlcon);
       // OleDbDataAdapter
        DataSet myds = new DataSet();
        sqlcon.Open();
        myda.Fill(myds);
        Repeater1.DataSource = myds;
        Repeater1.DataBind();
        sqlcon.Close();
