NDISUIO 802.11 BSS List Scan and Disassociate problem

Hi,

I'm writing an .NET app to grab RSSIs from a 4150 and Prism card. But if the
PPC is associated with an AP, the RSSI data from OID_802_11_BSSID_LIST will
stay at the same value as the time the PPC just associated.

I can only use OID_802_11_RSSI to grab RSSI from associated AP. But I want
to grab all RSSI from nearby AP.

I found some ways to do the job but none of them work for me:

1. Set the OID_802_11_BSSID_LIST_SCAN to force a scan, but it always return
error 87.
2. Set the OID_802_11_DISASSOCIATE to force a disassociation, but it always
return error 87.
3. Set the OID_802_11_SSID with a unused AP name to force disassociation
temporarily, it always return 87 also.
4. Set the OID_DOT11_SCAN_REQUEST to force scan, still error 87.

I didn't issue IOCTL_NDISUIO_OPEN_DEVICE so I send device name in each
QUERY/SET command. I tried to issue OPEN_DEVICE command but it always return
31.

My set command is:

result = Window.DeviceIoControl(
this._hHandle,
Window.IOCTL_NDISUIO_SET_OID_VALUE,
lpInBuffer,
(uint) inBuffer.Length,
(byte *) 0,
0,
&bytesReturned,
IntPtr.Zero );

Can anyone help me?

Also, I want to ask how to grab NDIS_STATUS error code? Is that same as the
error code from GetLastError()? If yes, how to convert it to NDIS_STATUS
code (in NDIS.H)?

Thanks a lot,

Fixed, I got a bug in NDISUIO struct code.

btw, how to get the NDIS_STATUS error?
