Is it possible to "grab" the mouse (meaning making the cursor disappear, and preventing it from actually moving) using the raw input API? I've tried using the RIDEV_CAPTUREMOUSE flag when defining my raw input device, but it doesn't seem to work (in fact, it makes it so that I don't receive ANY WM_INPUT messages). I'm looking to essentially recreate what happens with DirectInput when creating a mouse device with the exclusive and foreground flags. Is this possible?

That did the trick! Thanks :)
