Re: WM_CTLCOLORBTN message

Hello,

it's really a problem with most common controls: they don't deal well
with transparency. what you really need to do is capture a part of the
background picture that lies underneath the radiobutton, create a
pattern brush from it and let it use that to 'paint' background.

or alternatively you may paint captured picture part in WM_CTLCOLOR
handler and return NULL_BRUSH. this may be a little bit easier to
code.

p.s. after messing with radiobutton transparency for several days I
just asked our UI designer to always make radiobutton background solid
whenever possible. :-)
