如何使用MFC监视文件 [英] How to Monitor the files using MFC

问题描述

你好

我正在MFC中开发应用程序，我的应用程序需要监视系统中已重命名或删除或创建了该文件的所有目录.我还必须记录所有这些内容以及路径，时间和名称的文件.

我一直在网上寻找，但是我发现大多数使用C#的文件监视程序，但是我需要在MFC中进行开发，因此，任何人都可以指导我在MFC中完成此操作.

在Advance中致谢

推荐答案

可以通过WMI完成，所以请使用MFC遍历WMI.

所需查询可以表述为:

It can be done with WMI, so please go thru WMI with MFC.

The required query can be formulated as :

SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name='C:\\Test\\MyFolderToMonitor'"

现在，您可以使用它来构建基于WMI的文件更改通知事件.

可能对您有帮助吗?

Now you can use this to build WMI based File Change notification event.

May this too help you:

看看

Have a look at Change Journals[^]. It''s better than using FindFirstChangeNotification or ReadDirectoryChangesW.
