不知道是不是Windows7 的Bug

Question

在WinXP中调用SHFileOperation，复制文件时，如果目标文件存在，点取消按钮后，该函数会返回非0，而在Win7中返回值总是0，真是不可思议。

Answer 2

It is good practice to examine the value of the fAnyOperationsAborted member of the SHFILEOPSTRUCT. SHFileOperation can return 0 for success if the user cancels the operation. If you do not check fAnyOperationsAborted as well as the return value, you cannot know that the function accomplished the full task you asked of it and you might proceed under incorrect assumptions.

MSDN说的很清楚，最好检查fAnyOperationsAborted，如果用户取消操作，SHFileOperation也会返回0。
