[英]How do I get CopyFileEx to report back so I can cancel a file copy operation?
I'm trying to use the FileUtilities.CopyFile
wrapper for CopyFileEx
from here . 我正在尝试从此处使用
CopyFileEx
的FileUtilities.CopyFile
包装器。 But the CopyFileCallbackAction
doesn't get called until after the file is copied (I've tried copying a large file). 但是在复制文件之后才会调用
CopyFileCallbackAction
(我试过复制一个大文件)。 How do I get it to report back so I can cancel the copy if the user so wishes? 我如何让它报告回来,如果用户愿意,我可以取消该副本?
