I have a c++ program with a window, then i destroy the window, but keep the program running, as a process. the standard method of key detection

if (keys['W'])
{
  ...
}

this doesn't work, how else can I detect key presses.

Just an idea... never tried it...


What if you move the key message detection routine (WM_KEY...)
next to the WM_QUIT detection in the main loop? because the key message will not be sent to the window anymore...

ill try, and let you know.

It didn't work, sorry but thanks for trying.

I am using the code from lesson one, what i want to do, is have some code that lets me detect key presses after the KillGLWindow command, and before the return in the WinMain function

You only get Key Messages as long as your window is present / your Window Message Loop runs. So after the HWND gets invalid, there is no possibility to get Key Messages the easy way. But you could use Direct Input, it doesn't need a window.

DirectInput - does - need a window (SetCooperativeLevel()), but it doesn't need it to be on the foreground (aka in focus).

Are you sure ? Well, may be.

I need a program that can run in the background, and not be on the taskbar. Sortof Like how windows detects ctrl alt del and alt tab etc...

Can I destroy the Window but keep HWND valid?

There must be a way to do this?

I solved the problem, I was reading some stuff on msdn when i came across the GetKeyState() func, whic works perfectly

Great, just what we need. More trojan-horse programmers.
