VC（MFC）判断文件/目录是否存在,创建目录

BOOL CPubFunc::FileExist(CString FileName){ CFileFind fFind; return fFind.FindFile(FileName); }BOOL CPubFunc::DirectoryExist(CString Path){ WIN32_FIND_DATA fd; BOOL ret = FALSE;    HANDLE hFind = FindFirstFile(Path, &fd);    if ((hFind != INVALID_HANDLE_VALUE) && (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))    {  //目录存在  ret = TRUE;        }    FindClose(hFind); return ret;}BOOL CPubFunc::CreateDirectory(CString path){ SECURITY_ATTRIBUTES attrib; attrib.bInheritHandle = FALSE; attrib.lpSecurityDescriptor = NULL; attrib.nLength = sizeof(SECURITY_ATTRIBUTES);  return ::CreateDirectory( path, &attrib);}
