c++ - How to integrate windows/Internet explorer's internet properties options and proxy?

Question

I wonder if what APIs does Chrome uses when working with proxies. I noticed that when you try and set the proxy (thru Settings->Advanced->Open Proxy Settings) It pop's up a window (Internet Properties) in which I noticed running from rundll32.exe. So I wonder, how do I simulate this in my own application? (C++)

I wanna put a button on my GUI application, and when it's clicked, pop's-up the Internet Proerties Window where the user can see the proxies options and set it too if they want, just like chrome's and internet explorer's. Do I simply launch rundll32.exe with the same arguments as chrome passed to it? or is there any other APIs that automatically does this?

And how do I get those proxy settings entered by the user? Thanks.
