Depends on if you are doing it in blitz+ or blitz3D. There are a couple more steps involved with blitz3D.
All you really need is the HWND of the blitz window then you can do whatever you want, override it message function even, which isn't that good idea since then all the Keyboard functions wont work.
If you want some code just ask.
