如何获取局域网的所有计算机和对应的IP地址,非常感谢最好能给个实例.

[此贴子已经被作者于2007-3-4 22:12:28编辑过]

其实 这个还不如不写程序呢?
局域网一般都有网上邻居,你只要知道自己的ip和机号一般都能推算.

我在用程序来枚举局域网的所有计算机呀!!!

谁能帮我呀!!!!

我想反正会用到API函数

那位好心人帮帮我呀!!!!
我现在急要用程序来枚举局域网内的所有计算机和对应的IP地址.

Net view
显示域列表、计算机列表或者由指定计算机共享的资源。

net view [\\computername | /domain[:domainname]]

net view /network:nw [\\computername]

参数

无

如果在没有参数的情况下使用，则 net view 显示当前域中的计算机列表。

\\computername

指定要查看其共享资源的计算机。

/domain[:domainname]

指定要查看其可用计算机的域。如果省略了 domainname，将显示网络中所有的域。

/network:nw

显示 NetWare 网络上所有可用的服务器。如果指定了计算机名，将显示 NetWare 网络中该计算机上的可用资源。添加到该系统的其他网络也可以使用该开关指定。

这个命令我知道,有没有不用这个命令的方法,或用API等直接在VB程序在枚举

版主非常感谢你热心的帮助,可是运行会出错!

lreturn = wnetopenenum(resource_globalnet, resourcetype_any, resourceusage_all, byval 0&, henum)



(我用的是XP SP2系统)

这问题解决了,运行的结果是:
network... Microso
network... Microso
network... Web Cli
这个是网上邻居的整个目录下面的三个,这个不是我想要的结果呀!我是要整个局域网的计算机名称和IP,不是这三网络呀!
