SqlConnection con = new SqlConnection(cn.getcon());
            if (con.State == ConnectionState.Open)
                con.Close();
            con.Open();
            SqlCommand cmd;
            SqlCommand cmd1;
            SqlDataAdapter dr1;
            SqlDataAdapter dr;  
            cmd = new SqlCommand("select * from sabha00a where s00a0004<='" + A00D0001.Value.ToString("yyyy-MM-dd") + "'",con);
            dr=cmd.ExecuteReader();
            while (dr.Read())
            {
                cmd1 = new SqlCommand("select * from milka00b where a00b0002=" + dr[0].ToString() + "",con);
                dr1 = cmd1.ExecuteReader(); 
            }
            con.Close();
