I changed the value of my controls. For example, a Text Box<br>was bound to a RDC, First, Addnew; Second, I changed the text of <br>the Text Box; Third, Update. Then a prompt is displayed. And the<br>count of SQL table's rdocolumns is 1.<br>If I use same method with Access Table and Data Control, Success. <br>But with SQL Table and RDC, then failure.<p>: 要将目前 form 上 data-aware 控制项的资料手动写入资料库的话，必须从 RDC 控制项上着手。因我没试过，你先试看看好了，若试不出来我再帮你查资料。<br>Please help me. Thanks.<br><br><p><a name="followups">Follow Ups:</a><br><ul><!--insert: 1853--></ul><!--end: 1853--><br><HR><p></body></html>⌨️ 快捷键说明
