/*
Send notification. depends on dispinfoW having same
structure as dispinfoA.
With testing on Windows 2000 it looks like the notify format
has nothing to do with this message. It ALWAYS seems to be
in ansi format.
infoPtr : listview struct
notificationCode : *Unicode* notification code
pdi : dispinfo structure (can be unicode or ansi)
