Answer 2

做64bit exe，然后如下代码void EnableNetDevice(bool aState, int index)
{
  HDEVINFO NetPnPHandle;
  SP_PROPCHANGE_PARAMS PCHP;
  SP_DEVINFO_DATA DeviceData;
  NetPnPHandle = SetupDiGetClassDevs(&GUID_DEVCLASS_NET, 0, 0, DIGCF_PRESENT);  if (NetPnPHandle == INVALID_HANDLE_VALUE)
  {
        return;
  }  DeviceData.cbSize = sizeof(SP_DEVINFO_DATA);
  SetupDiEnumDeviceInfo(NetPnPHandle, index, &DeviceData);
  PCHP.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);  if (SetupDiSetClassInstallParams(NetPnPHandle,&DeviceData,&PCHP.ClassInstallHeader,sizeof(SP_PROPCHANGE_PARAMS)))
  {
        PCHP.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);
        PCHP.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
        PCHP.HwProfile = 0;
        PCHP.Scope = DICS_FLAG_CONFIGSPECIFIC;
        if (aState) PCHP.StateChange = DICS_ENABLE;
        else  PCHP.StateChange = DICS_DISABLE;
        SetupDiSetClassInstallParams(NetPnPHandle,&DeviceData,&PCHP.ClassInstallHeader,sizeof(SP_PROPCHANGE_PARAMS));
        SetupDiCallClassInstaller(DIF_PROPERTYCHANGE,NetPnPHandle,&DeviceData);
  }  DeviceData.cbSize = sizeof(SP_DEVINFO_DATA);
  SetupDiDestroyDeviceInfoList(NetPnPHandle);
}
