推荐答案

您根本不需要这样做.

更改屏幕分辨率绝对不是一个好主意，因为这会影响计算机上运行的所有其他应用程序，并且在执行此操作时也会完全更改用户桌面图标的布局.

也尝试在多监视器设置中执行此操作，问题将变得更加严重.您将如何知道您的应用程序在哪个监视器上并跟踪您要更改的监视器?

You shouldn''t need to do this AT ALL.

Changing the screen resolution is a HUGELY bad idea because you affect all other applications running on the machine and you also completely change the layout of the users desktop icons when you do that.

Try doing this in a multiple monitor setup too and the problem gets even worse. How are you going to know which monitor your app is on and track which one you''re going change??

我想只要您的表单被停用，您就想重置重排.如果是这样，则可以使用以下形式的Deactivate事件:....

I think whenever your form get deactivated then you want to reset the reoslution. If it is, than you can use Deactivate event of form.....
