如何取得网卡的友好名称？

老幺，楼主等好久了:)CSDN论坛浏览器:浏览、发帖、回复、结贴自动平均给分,下载地址:http://CoolSlob.ys168.com

看看注册表的这个目录下面的内容，是不是你要的。HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}\CSDN论坛浏览器:浏览、发帖、回复、结贴自动平均给分,下载地址:http://CoolSlob.ys168.com

以上代码在WinXP SP2 + Delphi7上调试成功。运行后获取到类似以下内容：连接名称: RTL8139, 设备名称: Realtek RTL8139 Family PCI Fast Ethernet NIC
连接名称: vNet1, 设备名称: VMware Virtual Ethernet Adapter for VMnet1
连接名称: vNet8, 设备名称: VMware Virtual Ethernet Adapter for VMnet8
连接名称: ADSL, 设备名称: USB ADSL LAN Adapter

在我的电脑上报AV错误
系统是XP sp2,D7 由于是笔记本，关了不少我认为不需要的服务，不知道你这个是不是要依赖什么服务?CoCreateInstance(CLSID_ConnectionManager, nil, CLSCTX_SERVER,
IID_INetConnectionManager, pManager);
应该是这句没有正确地取得pManager;
在if SUCCEEDED(pManager.EnumConnections(NCME_DEFAULT, pEnum)) then报AV错。
