请大家帮忙，如何获得网卡名称，多谢大家了

我早都关注这个帖子了，正在搜索MSDNing...

NdisMQueryAdapterInstanceName retrieves the friendly name of a physical NIC or a virtual adapter.
NDIS_STATUS
  NdisMQueryAdapterInstanceName(
    OUT PNDIS_STRING  AdapterInstanceName,
    IN NDIS_HANDLE  MiniportAdapterHandle
    );http://msdn.microsoft.com/library/default.asp?url=/library/en-us/network/hh/network/NdisXMd_Mz_a20f1c3a-afb9-46e2-9c3c-19432a94716a.xml.asp

从MSDN中查到，NdisMQueryAdapterInstanceName应该可以得到你需要的。

利用注册表，vc.net测试通过#include "stdafx.h"
#include <windows.h>
#include <atlstr.h>
#include <assert.h>int _tmain(int argc, _TCHAR* argv[])
{
HKEY hKey;
CString strSubKeyName = _T("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\NetworkCards");
if ( ERROR_SUCCESS != ::RegOpenKeyEx(HKEY_LOCAL_MACHINE, strSubKeyName, 0, KEY_ALL_ACCESS, &hKey) )
{
printf("没有网卡\n");
}// end of if
LONG RetCode = 0;
for( int i=0; ; i++ )
{
CString strEnumedSubKey;
TCHAR str[200];
DWORD dw = 200;
if( ERROR_SUCCESS != RegEnumKeyEx(hKey,i,str,&dw,NULL,NULL,NULL,NULL))
{
break;
}
strEnumedSubKey = strSubKeyName + CString(_T("\\") + CString(str)); HKEY hNetCardKey;
assert( ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_LOCAL_MACHINE,strEnumedSubKey,0,KEY_ALL_ACCESS,&hNetCardKey));

DWORD cbdw = 1000;
BYTE bDate[1000];
DWORD valType = REG_SZ;
if( ERROR_SUCCESS == ::RegQueryValueEx(hNetCardKey,_T("Description"),NULL,&valType,(LPBYTE)bDate,&cbdw))
{
printf("第%d块网卡：%s\n",i+1,CString(bDate));
}
}// end of for return 0;
}

那我不在windows下运行怎么办啊?

晕，不是windows环境你跑到vc版问？

楼主，为了你这个帖子，许多朋友今天都来找我，结果你居然不是windows环境！ft

不好意思,我实在是找不到地方问了,去了C里面问了,可是没什么人能回答阿,可能是大家都比较忙吧.我在网上搜索的有利用DeviceIoControl CreateFile GUID HANDLE 等的，但是总是没调通。
在windows下也行，但是我怕windows的版太多了，不能稳定运行阿（网卡在注册表里面的路径），希望大家在帮我看看，再次感谢大家！

楼主呀，你…………你……我就不说了，vc++不在windows下运行，你把它安装到哪里？

我们软件需要用户选择网卡，目前可以只考虑在windows这种环境下。我们是想获得网卡的名称和带宽信息。
目前，我们获得的网卡名称像这样：“NDIS 5.0 ”（这是从WinPCap中获得的）。这样可读性太差了。
我们希望获得如这样的显示：“Realtek RTL8139 Family PCI Fast Ethernet NIC”。
还有就是获得网卡的带宽：如是10M的还是100M的等。如果是自适应的我们想获得当前的带宽是多少。通过大家的指教，我想从注册表中获得显卡名称是没问题了，但是怎样获得带宽呢？此外，除了读注册表，我们尝试使用CreateFile()获得网卡的句柄，然后用DeviceIOControl()获得网卡的相关信息，但没有尝试成功，不知道这种方法行不行。

ft，在这的都些什么人啊？！
MSDN，查GetAdaptersInfo函数
或用SetupApi函数

调试易
