推荐答案

嗯，您在执行此任务时遇到了主要问题.

1-如果您的其他任务在写入文件时尝试读取该文件怎么办?多久写一次?
2-如何确保在读取和删除文件之间没有任何文件写入文件?

忽略这些问题，以及将击键发送到不在您的应用程序中的另一个窗口(但是您可以通过发送窗口WM消息来完成)的令人难以置信的hack，您只需在服务中设置文件监视程序即可监视地点.它不一定是一项服务，但听起来像您想要的那样.

Well, you have major issues with this task.

1 - what if your other task tries to read the file when it''s being written ? How often will it be written ?
2 - how do you make sure nothing is written to the file between you reading it and you deleting it ?

Ignoring these issues, and the incredible hack that is sending keystrokes to another window that''s not in your app ( but you can do it by sending the window WM messages ), you just set up a file watcher in a service that watches that location. It doesn''t have to be a service, but it sounds like you''d want it to be.
