Hi ,.
thanks for your help ,
i have opened the device handle.
but i m getting invalid parameter error when i m trying to use the following
call after it
pQueryOid = (PNDISUIO_QUERY_OID)&QueryBuffer[o];
pQueryOid->Oid = (NDIS_OID)OidCode
DeviceIoControl(hMac,
//handle obtained after create file and IOCTL_NDISUIO_OPEN_DEVICE
IOCTL_NDISUIO_QUERY_OID_VALUE,
(LPVOID)pQueryOid,
sizeof(NDISUIO_QUERY_OID) + sizeof(DWORD)
MyReturnedCount,
lpOverlapped)
please advice me.
can i use the above call fo all the OIDS eg for fetching BSSID list
or only for long values.
thanks

You would not use CreateFile( adaptername, ... ) to do that. Look up
NDISUIO and use that to send OIDs to the driver. Obviously, Windows CE is
*not* XP, so expecting this back door method of accessing drivers from
applications to work the same is, at best, naive.

Hi,
i m trying to configure n check the driver using oids.
hence i m trying to open the interface to get a valid handle.
is there any other call which you would advice to achieve the same or
there
is some important thing i m missing out.
i would like to mention here that the same call succedds in normal xp
desktops.
thanks

No, that's still not what you're trying to do; it's how you're trying to
do
it. You want to, what, send raw packets over the interface? Query some
status or information about the interface?
