c++ - 错误124- SHFileOperation的系统调用级别不正确

我正在尝试使用SHFileOperation将文件/目录从一个位置复制到另一位置。
到目前为止，我的代码是

    for(int index=0; index < clbSource.GetCount();index++ )
    {
        SHFILEOPSTRUCT SHFileOp;
        CString src,dest;
        std::string NULLTermination="\\0\\0";

        //Get source file/directory path from CListBox
        int n = clbSource.GetTextLen(index);
        clbSource.GetText(index, src.GetBuffer(n));
        src.ReleaseBuffer();
        CT2CA pszConvertedAnsiString (src);
        std::string strStdS (pszConvertedAnsiString);

        //replace single slash with double
        size_t found = 0, next = 0;
        while( (found = strStdS.find('\\', next)) != std::string::npos )
        {
        strStdS.insert(found, "\\");
        next = found+4;
        }

        //Add double null termination
        strStdS.append(NULLTermination);
        std::wstring stempS = s2ws(strStdS);

        //Get source file/directory path from CListBox
        int m = clbDest.GetTextLen(index);
        clbDest.GetText(index, dest.GetBuffer(n));
        dest.ReleaseBuffer();
        CT2CA pszConvertedAnsiStringd (dest);
        std::string strStdD (pszConvertedAnsiStringd);

        //replace single slash with double
        size_t foundD = 0, nextD = 0;
        while( (foundD = strStdD.find('\\', nextD)) != std::string::npos )
        {
        strStdD.insert(foundD, "\\");
        nextD = foundD+4;
        }

        //Add double null termination
        strStdD.append(NULLTermination);
        std::wstring stempD = s2ws(strStdD);


        //  set up File Operation structure
        ZeroMemory(&SHFileOp, sizeof(SHFILEOPSTRUCT));

        // application the owner of the progress dialog.
        SHFileOp.hwnd = GetSafeHwnd();
        SHFileOp.wFunc = FO_COPY;

        SHFileOp.pFrom = stempS.c_str();
        //SHFileOp.pFrom = _T("E:\\backup\\java softwares\0\0");

        SHFileOp.pTo = stempD.c_str();
        //SHFileOp.pTo = _T("E:\\Tmp\0\0");

        // Set the flags.
        SHFileOp.fFlags = FOF_SIMPLEPROGRESS;

        // Do it.
        DWORD result = SHFileOperation(&SHFileOp);

        //Check for success
        if(result!=0)
        {
        ::AfxMessageBox(ERR_MSG_FAILED_TO_COPY);
        }
        else
            ::AfxMessageBox(SUCCESS);

    }

现在，结果为非零，即124。
也通过此链接System Error 124 - ERROR_INVALID_LEVEL with SHFileOperation。
无法理解问题所在。

注意：如果将硬编码的值（如图所示）传递给'SHFileOp.pFrom'和'SHFileOp.pTo'，则可以正常使用。

谁能帮忙？

最佳答案

SHFileOperation由于“历史原因”不返回标准Windows错误代码。

MSDN:SHFileOperation，在“返回值”下有一个可能结果的列表。


  124 == 0x7C ==源或目标中的路径或两者均无效。


检查您实际上在结构中传递的值，路径转换中可能存在错误。
