MFC下判断文件夹是否存在，如不存在则创建文件夹

void CWireLessDlg::CreatePakcetFile()
{
 CString   strFolderPath;
 strFolderPath = _T("D:\\无线通信板报文存储文件夹");
 if(!PathIsDirectory(strFolderPath))//判断路径是否存在     
 　　 CreateDirectory(strFolderPath,NULL);//新建文件夹
 strFolderPath = _T("D:\\无线通信板报文存储文件夹\\UDP");
 if(!PathIsDirectory(strFolderPath))//判断路径是否存在     
 　　 CreateDirectory(strFolderPath,NULL);//新建文件夹
}
