Some inquiries

I'm wakafa, I'm quite interested in your project. However, some parts of your source is beyond me, so I would like to ask some questions, I beg your return.

1. What's your GIT developmental environment and OS?
2. How can you employ so many sophisticaed Win32_API ? As far as i'm concerned, such functions are pretty easy to forget, did you refer to some related books or documents on the Internet ?
3. With respect to source file, what's the procedure of packaging some other files into .res (and of course .rc) and link them into your executeable file ? Did you do it with shell or with tools provided by IDE ?

Thank you for reading.
