Yes, the case is significant and that means that Handle and HANDLE
aren't the same, apparently HANDLE is specific to the win32 api (which
I don't know well), a rapid inspection of System.Win32.File seems to
reveal that the only function to get an HANDLE is createFile which has
a ton of parameters you'll need to set carefully to avoid overwriting
your existing file (you should probably define another function with
most of these already fixed for convenience) but should do the trick.

Good luck.
