I am trying to write a vb script or in .NET to grab all the available SSID's
and their signal strengths that the wireless card detects and dump it
into a file.


This is what i found on the net

' VBScript source code
on error resume next
set objSWbemServices = GetObject("winmgmts:\\.\root\wmi")
set colInstances = objSwbemServices.ExecQuery("SELECT * FROM
MSNdis_80211_BSSIList")
for each obj in colInstances
if left(obj.InstanceName, 4) <> "WAN " and right(obj.InstanceName, 8)
<> "Miniport" then
for each rawssid in obj.Ndis80211BSSIList
ssid = ""
for i=0 to ubound(rawssid.Ndis80211SSid)
decval = rawssid.Ndis80211Ssid(i)
if (decval > 31 AND decval < 127) then
ssid = ssid & Chr(decval)
end if
next
wscript.echo ssid
next
end if
next

I wrote a similar program in C#. NET using the System.Management
namespace to no avail.

Except the first entry everything else returns garbage. I did some
research on the internet and found out that it was because of a bug in
SP2. I got the same result when i tried to write an application in C#
using the System.Management namespace. I need a fix for this quickly.

Kindly help and all thanks in advance.


I would ideally like to keep it to using WMI and lightweight.

ideally it should work with 2000/XP SP1 and SP2 and with all wireless cards. 

Thanks
