Hi,
I have an MFC application and that starts execution when windows starts.When the application ends, It keeps a log file in temp folder. Some times,when improper shut down occurs, my application ends without writing the log file. How can I remove this situation? how can we know system status like shut down, system locked etc.. Please give some hints.

Thanks

推荐答案

只要发生任何更改，就立即写入日志?还是像MS Word的自动保存一样定期更新?

Write the log immediately, whenever some change occurs? Or update it periodically, like MS Word''s auto-save?

看看WM_QUERYENDSESSION消息:
