I created a new XCode project using the Carbon C++ Application
template.  This creates a project with a small number of template
classes to get a Carbon application going: TWindow, TCarbonEvent,
TEventHandler, TApplication, and a few others.

I'm trying to run code which reads a number of different file formats.
So, I have a for loop that loops over my different reader modules and
checks to see if the current module is capable of reading the file
based on the extension. This code is part of a static library.

first off, i posted to the wrong group in the other posting (lang.obj-c)
and forgot to crosspost.
if i declare an autorelease string it will release when the method ends.  
that's a given.

I had two methods that when called would add a number to a field.
Since they both did the same thing I decided to create a function that
both the methods could call.

should already have an object in the store.) I haven't really figured
out where the best place to do that is. awakeFromNib seems like a bad

what is the preferred way to read Booleans with CFPreferences?
I tried two strategies, but cannot make a decision on either the first

I am new Mac user, but an experienced programmer. I know little about
Cocoa (for now) so I would appreciate your input on a small project I
have.
I want to build a small application, to be run on the background,

I am working on software update for my application (which runs at boot
time.). I want to check for software update only after the user has
logged in, not just a single user but for any newly created user on the
machine. My application runs on 10.2, 10.3 and 10.4.

i know what i'd like to see, an automatic incremental compile number
based on the number of times that project was compiled.  can i have
xcode run a command for a project before every build but after it saves
it's files?  if so, i can write one small routine that increments a
