推荐答案

不，我不认为你理解不同的例程在VB中的交互方式。 />

想法是你的 For 循环正在对数据进行校正，不断检查变量 UserWantsOut 的值，看看是否需要停止。按钮的Click事件只是将其设置为True。您在Click事件过程中放置​​的 DoEvents ，如果测试和退出不属于那里。它们应该放在For循环中。

No, I don''t think you''re understanding the way different routines interact in VB.

The idea is that your For loop which is doing the correction to the data keeps checking the value of the variable UserWantsOut, to see whether it needs to stop. The Click event for the button simply sets it to True. The DoEvents, If test and Exit For that you have placed in the Click event procedure don''t belong there. They should have been put inside the For loop.

Private Sub Command1_Click（）

UserWantsOut = True

DoEvents

如果UserWantsOut那么

退出

结束如果
