How to receive input?

I have a command prompt application that opens certain programs and waits for certain input.

Lets say it opens Firefox, how can I make my application still receive input without having to switch over to my application

using
GetAsyncKeyState Function (Windows)

Does that still work even though my program isnt the main window I am working on? Lets say I am using Firefox, would it still receive everything I type?

Your best bet would be SetWindowsHookEx with a WH_KEYBOARD hook.

dont complicate.

Yes GetAsyncKeyState will work without anykind of focus to the window.

Ok, thankyou

[highlight=c++]for(int i = 0; i < 255; i++)
{
if(GetAsyncKeyState(i))
{
//Do some shit here
}
}[/highlight]

Not really efficient to keep calling GetAsyncKeyState in an endless for/while loop (no to mention the fact that another apps can get the recently pressed bit instead of yours). Even if you were to stick that in a thread it'd be plain ugly -

If you're wanting to log everything My vote goes for the hook (hell, I think I even made a post about a keyboard hook ages ago..)

Edit: yeah here ya go: http://www.mpgh.net/forum/31-c-c/948...rd-hook-c.html
That sample basically checks for a certain key press (page Up in this case) and does 'something'

Or something similar (full blown keyboard logger) in asm http://www.mpgh.net/forum/34-assembl...kb-logger.html
