wireles network

Question

Hi

I would like to programmatically detect a wireless network that a computer is contected to and be able to detect the settings of the wireless network that i have joined (e.g. security type, password or Hex code) , what type of components should i be using? and is there any code out there that you are aware of?

i appreciate if someone can show the right direction so i can go the resource.

Thanks
Souhail
