请教怎么(VC/MFC)禁用指定的网卡(要有禁用无线的或禁用有线的两种选择)? 急救!

请问如何(VC/MFC)禁用指定的网卡(要有禁用无线的或禁用有线的两种选择)???? 急救!!
就是说要求能在(启用)禁用时可以选择是(启用)禁用无线网卡还是有线网卡
急救!!

lfchen  
你的方法好像禁用了所有网卡
如果禁用所有网卡的话可以根据GUID，不用枚举所有的设备，

档主的意思是想禁用无线网卡或普能的网卡其中一种是吧，

如果楼主想到了思路或找到答案请告诉我一下，我也想知道怎么做

[解决办法]
通过WMI class Win32_NetworkAdapter.Disable method.

subtype为硬件的hardwareId
这样你就可以开启禁用任何硬件了~`

[解决办法]
我已经找到了方法.
首先和普通的方法一样,根据GUID禁用网卡类设备,只是在禁用时枚举第i块网卡,读取其设备信息,读到有"wireless"这个串的就认为它是无线网卡,就对它使用禁用操作,否则就接着枚举第i+1块网卡,直到都枚举完.
