C++ Win32 API 删除带进度条的文件 [英] C++ Win32 API Delete file with progress bar

问题描述

使用windows api，有没有办法删除一个大文件(比如1gb+)，并以某种方式监控进度?我确定这是可能的，但我不知道从哪里开始..

Using the windows api, is there any way to delete a large file (lets say 1gb+), and monitor the progress somehow? I'm sure its possible but I have no idea where to start..

应该更具体，我想将文件移动到回收站，并显示一个类似于探索的进度条，尽管我可能想要控制台或其他东西中的进度条，所以我不想要精确的复制品.

Should have been more specific, I want to move the file to the recycle bin, and show a progress bar similar to explores, though I might want the progress bar in a console or something so I don't want an exact replica.

编辑 2:是的，我猜它是即时的，应该在我问这个问题之前测试过.无论如何要结束这个问题?

EDIT 2: Yeaah guess it is instant, should have tested before I asked the question. Anyway to just close this question?

推荐答案

使用 SHFileOperation 使用 FO_DELETE func 和 FOF_ALLOWUNDO 标志将文件移动到回收站.除非您还指定 FOF_SILENT，否则将自动显示进度.

Use SHFileOperation with the FO_DELETE func and FOF_ALLOWUNDO flag to move a file to the Recycle Bin. Progress will automatically be shown unless you also specify FOF_SILENT.

SHFILEOPSTRUCT fileop = { 0 };
fileop.hwnd = hwndMain; /* your window */
fileop.wFunc = FO_DELETE;
fileop.pFrom = szFilePathToDelete;
fileop.fFlags = FOF_ALLOWUNDO /* | FOF_NOCONFIRMATION to recycle without prompting */;
int error = SHFileOperation(&fileop);

更新:如问题编辑中所述，不会显示单个文件的进度，但如果回收整个目录，则会显示进度.这也不允许您覆盖 UI(例如，在控制台窗口中显示进度).

Update: As noted in the question edit, progress won't be shown for a single file, but it will be shown if recycling an entire directory. This also doesn't let you override the UI (e.g., to display progress in a console window).
