TaskDialog implementation

I don't think it's appropriate to make selections for the user like
this. If you can't present all of the choices to the user, you should
probably return E_NOTIMPL.

Writing tests first would also help.

I think Lats' advice here is sound. You might start with a dialog with
only an OK button (that only displays if the dialog offers no choices
to the user), then add features one at a time.

Well, you shouldn't write it all at once anyway, as you'd likely have
to change all of your later work.
