Print out the value of 'n' in the else statement to find out and thus find out what went wrong.

Thanks so much for your reply.
Yes, as your advice, i add the output of "n",
the result is "1026".(it should be 0x402)

By the MSDN:
0x402 An unknown error occurred. This is typically due to an invalid path in the source or destination. This error does not occur on Windows Vista and later.

So i guess the fail may from the "invalid path". is it right?
(But in my PC, the path is true, with out any problem.)
Could you help me and give me some suggestions?

Both the pFrom and pTo members need to be double-null terminated, see the
SHFILEOPSTRUCT Structure documentation.

Thank you so much for your advice.

The problem is solved.
I have add a "\0" to the end of the string, which should be a double null terminated(i think).
anyway, here is the solution:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
std::string testto = "d:\\testto"
    SHFILEOPSTRUCT sf;
    memset(&sf,0,sizeof(sf));
	sf.hwnd = 0;
    sf.wFunc = FO_COPY;
	sf.pFrom = "d:\\testfrom";
	char d_te[] = "\0";
	std::string to = testto;
	to.append(d_te);
	sf.pTo = (LPCSTR) to.c_str();
    sf.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_NOERRORUI | FOF_SILENT;
std::string testto = "d:\\testto"
    SHFILEOPSTRUCT sf;
    memset(&sf,0,sizeof(sf));
	sf.hwnd = 0;
    sf.wFunc = FO_COPY;
	sf.pFrom = "d:\\testfrom";
	char d_te[] = "\0";
	std::string to = testto;
	to.append(d_te);
	sf.pTo = (LPCSTR) to.c_str();
    sf.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_NOERRORUI | FOF_SILENT;
