Guess what. Microsoft Spy++ lies!!

When it displays the parameters of the WM_CREATE and WM_NCCREATE messages
it gives the actual pointer value and also the contents pointed to by that
pointer.  In general it is correct but for the style and extended style it
doesn't give the hex value; it goes ahead and politely translates it for
you into WS_VISIBLE, WS_BORDER etc.  However it gets it wrong.  You can see
that it is wrong by 
1. creating your own class and a window of that class and see what it sends
you
or
 2. get the source code for the original spy program, modifying it a little
and using it.

Of course you can't get hold of the source for spy++ and correct it, as far
as I am aware.  (I'm getting to like this Open Source idea!!)

I wonder how many other lies spy++ tells us.
