resource.rc

Good Morning Friends, Alright?
    Please I need some help on the following questions:
    I am creating the type of IDE, and when I create a arquivo.c for example, and when I save
    the editor saves where I chose, cero? but the icon is not how I want.
    In short, I want when I create a file in my editor and save with extensão.c
    for example, it matches the icon you set for it in the resource file, also when
    save with extensão.cpp and so on, each file with its icon set.
    I've looked a lot on the web but without any results.
    I really want some help from you, From now Thank you and God Bless ...

Customising icons for files is not supported by design because it would confuse most users. What you can do is having different icon sets though.
