推荐答案

您可能会发现无法捕获实际的电源故障(请参见此处 [ ^ ])，因此在这种情况下您无法采取任何措施来保持自己的身份.最好的答案是，只要您的应用程序中的数据发生更改，都应尽快更新文件. You may find that it is not possible to capture an actual power failure (see here[^]) so there is no action that you can take to preserve your status in such a situation. The best answer would be to update your files as soon as possible whenever the data in your application changes.

CWinAppEx的对象会处理 CWinAppEx::LoadState(..)开头和 CWinAppEx::SaveState(..)退出时， 如果没有定义-由您-为您的CWinAppEx-公共应用程序... ...因此您也可以在保存状态"框架上放置工具栏按钮 随时显式调用第二个函数，而无需退出...:) An object of the CWinAppEx does process CWinAppEx::LoadState(..) at its starting and CWinAppEx::SaveState(..) at its exiting, when it was not defined else - by you - for your CWinAppEx-public application... ...so you could also place a toolbar button at your frame "Save state" to call the second function explicitly, at any time, without exiting... :)
