C++文件夹操作

学习了一下SHFileOperation函数的使用，用于对文件夹进行复制、重命名。

看到有些人用FindFile()、FindNextFile()这样的API自己来实现一个复制函数，感觉有现成的API就懒得另外写一个稳定性不确定的函数了。

/*
@brief 移动原文件夹及其中文件都指定的路径下
@param[in] lpszFromPath 源文件夹路径
@param[in] lpszToPath 目的文件夹路径
@return 移动是否成功
*/
static BOOL MoveFolder(CString strFromPath, CString strToPath)
{
int nLengthFrm = strFromPath.GetLength();
char *NewPathFrm = new char[nLengthFrm+2];
strncpy_s(NewPathFrm, nLengthFrm+2, strFromPath, nLengthFrm);
NewPathFrm[nLengthFrm] = '/0';
NewPathFrm[nLengthFrm+1] = '/0';

SHFILEOPSTRUCT FileOp;
ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT));
FileOp.fFlags = FOF_NOCONFIRMATION;
FileOp.hNameMappings = NULL;
FileOp.hwnd = NULL;
FileOp.lpszProgressTitle = NULL;
FileOp.pFrom = NewPathFrm;
FileOp.pTo = strToPath;
FileOp.wFunc = FO_MOVE;

return SHFileOperation(&FileOp) == 0;
}

/*
@brief 修改原文件夹的名字
@param[in] lpszFromPath 源文件夹路径
@param[in] lpszToPath 目的文件夹路径
@return 修改是否成功
*/
static BOOL ReNameFolder(CString strFromPath, CString strToPath)
{
int nLengthFrm = strFromPath.GetLength();
char *NewPathFrm = new char[nLengthFrm+2];
strncpy_s(NewPathFrm, nLengthFrm+2, strFromPath, nLengthFrm);
NewPathFrm[nLengthFrm] = '/0';
NewPathFrm[nLengthFrm+1] = '/0';

SHFILEOPSTRUCT FileOp;
ZeroMemory((void*)&FileOp,sizeof(SHFILEOPSTRUCT));
FileOp.fFlags = FOF_NOCONFIRMATION;

FileOp.hwnd = NULL;
FileOp.lpszProgressTitle = NULL;
FileOp.pFrom = NewPathFrm;
FileOp.pTo = strToPath;
FileOp.wFunc = FO_RENAME;

return SHFileOperation(&FileOp) == 0;
}
