C++ Hotkey to run function

Question

Hey looking to assign F1 as a hotkey to run a function. I have a windows 32 project with a Form, however the form will be in the background and not the active window when I press F1.

Is there a way to code a hotkey or shortcut so when I press F1 it will run that function even if the Form1 isn't active?

Think you need a global hook to do that. Related: http://stackoverflow.com/a/9149702/4581301 — user4581301, May 19 '17 at 20:47
I would look into how AutoHotKey does this. It's free. And it uses a bunch of dll calls, if I'm not mistaken. — TinkerTenorSoftwareGuy, May 19 '17 at 20:54

Have a look at the RegisterHotKey function.

It allows you to define a system-wide hot key. When the hot key is pressed, you will receive a WM_HOTKEY message even if your window is not active.
