I was looking for a way to automate the process of picking what
programs "Hide always", "Show always" or "Hide when unused" etc like
you can do manually by right clicking on your taskbar, going into
properties, then clicking the "Customize" button in the Notification
Area. I wrote a program that uses a tray icon and I didn't want the
icon to disappear but couldn't figure out a way to force XP to make my
icon "always show". A did a search but couldn't come up with anything
except someone else looking to do the same:
http://groups.google.com/groups?hl=...564.02000101092001%40enews.newsguy.com&rnum=1
Well I figured it out and decided I'd save someone some time should
they ever want to do the same thing. This is mainly for the
programmers out there so I will post it in a programming NG as well as
here in windowsxp.customize where the initial question was posed.
