谢谢，我会试一试..

Thanks, I''ll give that a try..

我使用的按钮是在子窗体上。因此onClick将打开以显示子表单字段中的数据，这是我想要检查的位置。我应该在主窗体'的OnLoad中尝试这段代码吗？

The button I am using is on a subform. So onClick it will open to display the data in the field of the subform, which is where I want to check. Should I try this code in the main form''s OnLoad?
