I am using Windows Xp sp1 ddk and I need set some OIDs of my wireless
card. How I can set OIDs 802.11 from user mode? What functios I need?
How do I use that functions?
Can I use DeviceIoControl with IOCTL_NDIS_QUERY_GLOBAL_STATS? How?

No. IOCTL_NDIS_QUERY_GLOBAL_STATS by design can not set OIDs, only get.
You can try WMI to set some 802.11 OIDs.

Hello,
I can query/set OID 802.11 with NDISUIO.
I'm usinig NDISUIO for query/set from user mode.
I want to set some OID but first I want query some OID like SSID.The
code is below but it's wrong because when I call GetLastError()after
DeviceIoControl, GetLastError() return 1.What happen?
Can you tell me what happen? and Can you tell where is the Ssid?
Please, help me!!!!

hAndle = CreateFile(devicename,
                    GENERIC_READ|GENERIC_WRITE,
                    0,
                    NULL,
                    OPEN_EXISTING,
                    FILE_ATTRIBUTE_NORMAL,
                    (HANDLE)INVALID_HANDLE_VALUE);


        dwErr = GetLastError();
        printf ("\nError al  ejecutar CreateFile: %d \n", dwErr);

//OID_802_11_SSID//
//Query using NDISUIO//
UCHAR QueryBuffer[sizeof(NDISUIO_QUERY_OID)+
sizeof(NDIS_802_11_SSID)];
PNDISUIO_QUERY_OID pQueryOid;



         pQueryOid = (PNDISUIO_QUERY_OID)&QueryBuffer[0];
         pQueryOid->Oid = OID_802_11_SSID;

        bl= DeviceIoControl (hAndle,
                              IOCTL_NDISUIO_QUERY_OID_VALUE, 
                              &QueryBuffer[0],sizeof(QueryBuffer),
                              &QueryBuffer[0],sizeof(QueryBuffer),
                              &dwReturned,
                              NULL);


        dwErr = GetLastError();
        printf ("\nError al  ejecutar DeviceIoControl: %d \n", dwErr);
