country code of wireless LAN adapter

[Guest]

here i am using deviceIOControl to get the country code of wireless LAN
adapter

code is as follows:

NDIS_OID ndisOid
//Atheros Specific OID
ndisOid = OID_ATH_REGULATORY_DOMAIN;

DeviceIoControl(theApp.m_hDevHandle,
IOCTL_NDIS_QUERY_GLOBAL_STATS,
(LPVOID)&ndisOid,
sizeof(ndisOid) + sizeof (ULONG) -1,
(LPVOID)&dwCountryCode,
sizeof(dwCountryCode),
&ulLen,
NULL);

this is working for WindowsXp, but not for Windows Vista.
can any body help me in this?????

to resolve this problem i got the information from MSDN site that it
need to use WMI through the class "MSNdis_80211_WEPStatus".
i have seen it through WMI browser. but not getting any relevent
information

Please open the device handle with READ permission.
All the rest should work in Vista as it worked in XP.
