Hey, Patrick.

Look at tests/listview.c for example to see how I load version 6 with
activation context API. It doesn't work for some reason for XP SP3 (a
glitch I don't understand), but works fine for everything else. All
you need is v6util.h.

Without version 6 activation this test is useless to run in auto mode,
it will never find TaskDialog entry points.

Thanks for your interest.
