如何让CopyFileEx回报，以便我可以取消文件复制操作？(How do I get CopyFileEx to report back so I can cancel a file copy operation?)

我想从这里使用CopyFileEx的FileUtilities.CopyFile包装器。 但CopyFileCallbackAction不会被调用，直到文件被复制（我试图复制一个大文件）。 如何让它回报，以便我可以取消复制，如果用户愿意？

请参阅为什么CopyFileEx会干扰winforms的FileUtilities.CopyFile包装？

I’m trying to use the FileUtilities.CopyFile wrapper for CopyFileEx from here . But the CopyFileCallbackAction doesn’t get called until after the file is copied (I’ve tried copying a large file). How do I get it to report back so I can cancel the copy if the user so wishes?

编辑我的问题（发送到为什么是CopyFileEx干扰 WinForms的FileUtilities.CopyFile 包装？ ）发送到答案（由david-heffernan ） - 我全都在一个线程。

编辑：不。看起来我有一个this.Update(); 失踪。 请参阅如何在显示表单后获取代码以运行？ （麻烦与“显示”。） 。

The edit to my question (sending to Why is FileUtilities.CopyFile wrapper for CopyFileEx interfering with winforms?) sends to the answer (by david-heffernan) – I had all on one thread.

EDIT: No. It seems that I had a this.Update(); missing. See How can I get code to run after a form is shown? (Trouble with "Shown".) .
