~Annoying Wireless Setting Tool~

I have been writing a little tool for setting the Wlan driver configuration over one week!
Guess what!
I just successful to access the SSID from driver site using DeviceIoControl() Orz..
Even though MSDN is not completed for this topic *DeviceIoControl() using Ndis Universal IO*...
All I have to do, is trial-and-error ..
and tons of pages using searching engine...
May the google could help me a lot....
:(
