怎样获得局域网中所有的计算机名和ip地址？

Question

一定要用api函数才能实现么？请作过的朋友指点一下，越详细越好！
谢谢！

Answer 1

我的想法：网内每一台机器装上你的软件，交换各自的LOCALADDRESS，形成并维护一个“路由表”

Answer 2

怎样获得局域网中所有的计算机名和ip地址,不用API是完全可以的，你去一个个抄下来就可以了。

如果是这样的话 那也不可能有h这类人了

Answer 4

fuzq(强强) ,你自以为是高手么？假设你是高手你就可以这么牛B么？你觉得骂一个初学者很过瘾么？CSDN里怎么会有你这种垃圾！污染环境！

Answer 5

这是我几年前做的一个枚举局域网内所有机器名及得到其IP地址的一段主程序。当时是用于局域网内的动态IP的管理。在WIN98下运行正常。当然你的机器要是加入了域。如需要我这里有编译好的程序.

哥哥，VC++的啊！
不过还是很感谢你！
等我的c++学好了以后再研究这段代码，现在先收藏！
