Hello, list. I am a hack programmer, so forgive what is probably an
obvious question. I'm working on a core data document based app that
uses bindings I've created in IB to control a master / detail
interface. Briefly, in XCode's xcdatamodel, there is a Person entity
with a name (String) an
Hello. I have an iPhone app (SDK 4.3) that uses symmetric key encryption (AES
256, through the CommonCrypto library). I have the parameters set to use pkcs7
padding, and an iv of all zeros (CBC mode). My question (somewhat off the
lists's topic, I'm afraid) is that I need to help our IT people g
OpenSSL is available for Windows, but I can't see how to feed it an encryption
key, just a passphrase which is (apparently) converted to a key. However, since
CommonCrypto's CCCrypt uses the key directly, that's what I've got.
I'll check Cygwin out. Thanks. (Anyone know how to feed OpenSSL a key
Hello. After further pain, I found the solution: openSSL allows -K (for the key
in hex) and -iv (for the initialization vector in hex). (BOTH must be supplied
if -K is used.) Consider this thread closed. Thanks to those who assisted.

Hello, List. I am a novice with CoreData and bindings and I've stumped
myself with this problem. I have created an xcdatamodel that contains
3 objects: an Account object with a relationship property
authorizedUsers, which is a to-many relationship with a Person object.
The Person object has
I'm posting this simply because I *thought* I had looked through all
of Apple's "bindings for beginners"-style documentation, but hadn't
seen this sort of dependent controller setup described. Sorry if it's
obvious or redundant
In the spirit of (finally) answering my own question (and i

I am still learning bindings and CoreData, but I have recently completed
another relatively basic program using both these technologies. I learn best by
seeing other people's code, so in that vein, I'm posting my source (iCredit is

Hello List,
I am writing a CoreData app with an entity controller bound to an NSTableView,
with the bindings created programmatically. Periodically, the program creates a
new NSManagedObject, sets default values, and adds it to the MOC. This works
fine. However, the NSTableView does not update i
Sorry. It was NOT the NSTableView's problem. I neglected to add:
[[self managedObjectContext] processPendingChanges];
after the NSManagedObject was created. Please disregard the previous post.

I changed the Apple Menu > System Preferences > Date & Time > Use a 24-hour
clock setting. However, as I mentioned, I'd really prefer not to make this a
system-wide change. I just find it odd that there would be no programmatic way
to change the NSDatePicker to a 24-hour clock. If there is

NSArrayControllers to mediate between the three Entities in my Model and three

I have run up against an apparent 10.6.2 bug in the NSTableView object.
Specifically, if NSTableViewSelectionHighlightStyleNone is set, the tableView
causes Assertion failures and other problems. Below is some code demonstrating
the problem. In any event, I need to emulate the None style for hig

Looks like

are lurking in the dark) Thanks for the tip!

Dear List,
I am using manual retain count memory management (started long before ARC was
available) for an iOS app. I have a UIDatePicker in an .xib file with its

inherits from UIViewController, and has an IBOutlet a
Sorry, I should have been more precise: The problem is progressive memory
growth each time the ViewController is displayed. If I add the [release], the
memory footprint reverts to its pre-viewcontroller display level each time the
VC is dismissed.
