本源代码实现对局域网内指定IP范围的检索，并列表给出计算机属性包括名称、工作组、用户名和MAC等。通过UDP协议获取局域网内计算机的属性CUDP类实现了UDP协议，该类从CSocket类派生。在CNbtStatDlg类中的OnBtnSend（）函数将查询所有的计算机，该函数启动NBtstatThread线程，该类的OnReceive（）显示所有的检索信息，而OnBtnSend函数将这些信息保存为文本文件-Source code to retrieve a specified IP range LAN, and lists the computer attributes are name, workgroup, user name and MAC. Through the UDP protocol to obtain the LAN computer property of the CUDP class implements the UDP protocol, the class derived from the CSocket class. In the CNbtStatDlg class in the OnBtnSend () function will query all the computer, the function to start the NBtstatThread thread, the OnReceive () to display all of the information retrieval, and the OnBtnSend function will these information is saved as a text file
