Keyboard focus without activation?

Hi, just wondering if anyone knows of a way to give a background window keyboard focus without activating it (and bringing it to the foreground)?

Currently, I'm using SetWindowPos to push it to the back, which is working well to keep it behind everything else, however, it only gets the mouse events, and I am unable to give it focus (to get key events) without bringing it to the foreground. Tried making the window a child of the desktop window, which screwed up more things than it was worth (though it did solve the focus/background window issue).

Any ideas?

I don't know of standard Windows messages will work.
An easy other way would be to use DirectInput.
Others might have other suggestions.

Thanks Elysia, but we are trying to stick to the core win32 api as much as possible, so DirectInput isn't an option at the moment.

You could theoretically place a hook for keyboard messages and monitor them. Heck, you could even steal the messages if you want.
You can also subclass the current window.
I don't know how well these options will work.
