I want to work with Wifi with Delphi. How?

Question

In my Delphi (on Windows Xp) program I'd like to check available WiFi networks. Do you have any idea how to do it? Best is probably to use MS WlanScan API function but I did not found an example. Can someone help me?

Answer 1

You can get to this also by performing a WMI query:

SELECT * FROM MSNdis_80211_ServiceSetIdentifier

If you are specifically looking for a delphi implementation, there is a WMI library available from Magenta Systems which includes complete source and may be freely used. The available download includes a compiled executable where you can try this query to see if it contains all of the data that you are looking for. The only disadvantage of this approach is that the WMI service must be running (it normally is so this is not that big of a problem).
