在 Windows 服务中使用 SHFileOperation
这是可能的，但是在 Windows 服务中使用 SHFileOperation 是否合适？ shell32.dll 中的所有这些 SHxxx API 函数似乎都是根据用户级程序编写的。 我可以确定 SHFileOperation 永远不会显示 GUI 吗？
It's possible, but is it appropriate to use SHFileOperation within a Windows service? All those SHxxx API functions in shell32.dll seem to have been written with user level programs in mind. Can I be certain SHFileOperation won't display GUI ever?

根据 SHFILEOPTSTRUCT 文档，您可以使用以下标志可防止出现任何 UI：
或（如果您的目标是 Windows Vista）
FOF_NO_UI，与上面的相同。查看Windows SDK中的
ShellAPI.h头文件，针对FOF_NO_UI的注释说“根本不显示任何UI”，因此我认为这是可以的使用SHFileOperation。According to the SHFILEOPTSTRUCT documentation, you can use the following flags to prevent any UI from appearing:
or (if you're targeting Windows Vista),
FOF_NO_UI, which is the same as the above.Looking in the
ShellAPI.hheader file in the Windows SDK, the comment againstFOF_NO_UIsays "don't display any UI at all", so from this I assume it's OK to useSHFileOperation.我想说，这并不是不合适或不建议的。 大多数 shell32 API 都是在编写时就基本了解它们将在交互式进程中使用。 我认为没有任何方法可以保证 SHFileOperation 永远不会显示 UI 组件。 事实上，如果您查看 IFileOperation（这是取代SHFileOperation的新Vista接口），它明确指出：
I would say, not it's not appropriate or advisable. Most of the shell32 APIs were written with a basic understanding that they would be used in interactive processes. I don't think there is any way you can guarantee that SHFileOperation will never display a UI component. In fact, if you look at IFileOperation (which is the new Vista interface that replaces SHFileOperation), it clearly states:
我必须同意：不合适或不建议。
使用 SHFileOperation 的主要原因是通过 UI 执行操作，和/或可逆的操作。 即，使用 SHFileOperation 删除文件会将文件放入回收站，而不是删除它们，从而允许当前交互用户取消删除或撤消所执行的操作。
由于服务在非交互式桌面上运行，因此没有人能够清除回收站。
I have to agree: not appropriate or advisable.
The prinicpal reason to use SHFileOperation is to perform operations with a UI, and/or which are reversable. I.e. using SHFileOperation to delete files is going to place the files in a recycle bin rather than deleting them allowing the current interactive user to undelete, or undo the operation performed.
As the services run on a non interactive desktop, no one will ever be able to clear that recycle bin out.
我也遇到了这个问题，并致力于在服务器和网络共享之间实现安全可靠的网络文件复制（大多数共享基于 CIFS / NetApp 文件管理器），并且
SHFileOperation有时会失败。现在开始使用 ROBOCOPY（默认情况下在 Vista/Server 2008 以上的所有 Microsoft 操作系统中可用），看起来确实很有趣且可靠。

I had this issue as well and working at implementing a secure and reliable network file copy between servers and network shares ( most of these shares are CIFS / NetApp filer based ) and
SHFileOperationfails from time to time.now started using
ROBOCOPY(available by default in all Microsoft OS from Vista/Server 2008 upwards) and really looks interesting and reliable.this has opened my eyes: https://stackoverflow.com/a/1030752/559144
