Using NSWorkspace's -launchApplication: is fine. If the app was already
running when you called it, the method won't do anything, as you can read
from the documentation.

I'm not sure you can actually do that.

Just praying. :-)
Apple should care about that, not you.

There are many approaches but if you don't tell us what are your purposes we
can't tell you wich approach is the best for your use. However, i suggest
googling for ScriptingBridge.

y messages?



What kind of task are you trying to accomplish? Are you sure you have to
know whether a dialog is open in iTunes? AFAIK you can't do anything
similar, in any application.
