VC（MFC）判断文件/目录是否存在

BOOL CPubFunc::FileExist(CString FileName)
{

return fFind.FindFile(FileName);
}

if ((hFind != INVALID_HANDLE_VALUE) && (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
{
ret = TRUE;
}

return ret;
}

BOOL CPubFunc::CreateDirectory(CString path)
{

attrib.bInheritHandle = FALSE;
attrib.lpSecurityDescriptor = NULL;
attrib.nLength = sizeof(SECURITY_ATTRIBUTES);

return ::CreateDirectory( path, &attrib);
}
