                                        cboHKQX.DataSource = dtProvince1;

                                        cboHKQX.DisplayMember = dtProvince1.Columns["Province"].ToString();

                                        cboHKQX.ValueMember = dtProvince1.Columns["GBcode"].ToString();

                                        cboHKQX.SelectedValue = ChronicDisease.body.data.B020100.VC_HKSHEN;

                                        cboHKQX.ValueMember = dtProvince1.Columns["GBcode"].ToString();
                                        cboHKQX.SelectedValue = ChronicDisease.body.data.B020100.VC_HKSHEN;
