请说明:
1、后台数据库是什么?如果用VFP表,多人操作很难提高速度。
2、数据是否分组(每个操作员,只能操作指定部分数据)?如分组的标志字段是什么?
3、如没有分组,同一条数据是否有可能被一个以上操作员写入?

Vfp表 已按录入员分组  每个录入员只能对自己录入的记录修改、删除  多人员可添加记录 按条件读取全部记录

改变一下设计思路,仅读取要修改记录,修改好后再对表进行锁定更新,效果会好很多

试试用select SQL 语句来筛选读取和更新表,可能效率会更高些。

档案号文本框(有两个事件:第一个GotFocus)筛选后恢复所有以供再次筛选
sele b_dagl
set filter to
set order to dahpxmlh
go top               
档案号文本框(第二个lostFocus)主要是筛选后将顶记录其他C1文本控件赋值,这一步如果一人操作时还可以,人越多越慢

         ("enabled",.f.)
          retu
    endif
    set filter to &mll
    count to clfs  &&统计材料份数等同记录个数
