In a DataWindow connected table, a new returning logo IFBack field is a checkbox (in the future, it is only written to a file.) Ifback = 0 indicates that the record is selected, ifback = 1 Indicates that it is not selected. But this logo is only written in a file after CLOSE. If this record is changed to 1 in the original record, the record is removed. Open, read this file, and then this field is placed back in this field. Many thanks. . . !!!
