我正在尝试验证表单中的QTY条目，如果用户没有输入任何内容或0，我会提示输入一条消息并且光标返回到QTY输入栏。
我在数量上尝试了迷失焦点 -
如果qty< = 0则
msgbox（请输入数量）
me.qty.SetFocus
结束如果
但光标总是跳到下一个输入框，我甚至替换为取消=真，它仍然无法工作，任何想法？
更改为After Update事件。展开 | 选择 | Wrap | 行号
但是，如果用户按Tab键或将鼠标移离此文本框，那么我不认为更新后可以检测到它，我是对的吗？

一旦输入控件，它应该触发更新后事件。但是，当然，您只需要在表单OnClose事件中调用该事件。展开 | 选择 | Wrap | 行号
I am trying to validate a QTY entry in a form , if user did not enter anything or 0 , I will prompt for a message and the cursor return to the QTY entry column.
I have tried Lost Focus in the Qty -
If qty <=0 then
msgbox("Please Enter Qty")
me.qty.SetFocus
end if
But the cursor alway jump to the next entry box, I even replace with Cancel=true, it still doesnt work, Any Idea ?I am trying to validate a QTY entry in a form , if user did not enter anything or 0 , I will prompt for a message and the cursor return to the QTY entry column.

But what if user press the Tab key or move the mouse away from this text box, then I don''t think After Update could detect it, Am I Right ?
