Help urgent !!

[Chouchou]

Hi everyone,

I need urgent help on a project I'm doing for my school concerning wifi (802.11) positioning using .NET and C#.

Do you know where I could find some help on coding ?

Thanks a lot !!

Chouchou,

It's kind of unclear from your post on what you are trying to accomplish. It seems like you are looking for Wi-Fi proximity libraries or components that you can plug into a .Net application and use to build your project.

AFAIK, there really aren't that many readily available - although their are some out there as well as commercial software products that will do this - if your project requires you to code - then the commerical products won't help you.

You might want to try to google 'wi-fi location' and do some further research

Ok, here are the details :)

I know how to retrieve the BSSIDs (wifi stations) and their attributes, but I don't know how to refresh the list whenever I want. Actually the BBSIDs list refreshes only when the card decides to. At the moment, I tried using this :

SELECT * FROM MSNdis_80211_BSSID_LIST_SCAN where active=true

but it doesn't seem to do anything at all.

I think I also may have some problems with understanding wql syntax. I know how to SELECT but I don't know how to SET an OID.

So the question is: how to refresh the list and how to use the SET keyword in wql. Thank you guys!!

Please help me or I'm a dead man :)

Thanks...
