how to rebind network adapter?

hi guys,

I want to update network IP address to 169.254.xx.xx (which means the
machine cannot connect to a DHCP server). I used to
IOCTL_NDIS_REBIND_ADAPTER to update it:


//---------------Code--------------------------------
TCHAR szReg1[]=L"VNETUSBA1\0\0"; //VNETUSBA1 is the Wi-fi adapter name

HANDLE g_hNdisUio = CreateFile( NDISUIO_DEVICE_NAME,GENERIC_READ |
GENERIC_WRITE,FILE_SHARE_READ | FILE_SHARE_WRITE,NULL, OPEN_ALWAYS, 0,
NULL);

DeviceIoControl(g_hNdisUio,IOCTL_NDIS_REBIND_ADAPT ER,szReg1,sizeof(szReg1),NULL,NULL,NULL,NULL);


//---------------End of Code-------------------------


Fuction DeviceIoControl always return Error 50: The network request is not
supported.

I tried IOCTL_NDIS_UNBIND_ADAPTER, same error.

Does anybody know the problem?

Thanks

Oscar

Use IP Helper functions (iphlp...)
NDISUIO is not for what you're trying to do.
