Drag & Drop: PREVENT file move

Hi! My application shows a list of files in a table view. I have implemented drag and drop so that users may drag files from the list. I could envision them dragging the files onto other applications for viewing or dragging them on a removable media to create archive copies. The problem

Announce the time every 30 minutes

Hell I'm trying to find out how to announce the time every 30 minutes, I'm guessing I have to do it with NSTimer and and than have the time interval set to NSDate interval from now to the time which is like 7:30 or 8:00. but I'm not sure. Thanks for the help, Mr. Gecko _

Re: Announce the time every 30 minutes

If you don't "need" this function "in" your app, or don't want to have your app running all the time just to do the chime, you could setup system preferences to let OSX do it for you. There may even be a command line that can be executed under control of your app. Gary On Dec 11, 2008, at

Re: Core Data warning: to-many relation does not have an inverse

Sorry if this ends up showing twice, but the original message has been moderator-queued for length since early this morning. Being several steps behind in even *asking* Core Data questions has been frustrating me all day, as I try to press on in no less ignorance than yesterday. On Dec 11,

Help reading cocoa docs - finding info about return objects and autorelease / memory management.

Hey All, Quick question, what is the best way to determine what kind of cleanup I need to do with objects that were returned from other objects' methods, or class methods. For example, the NSTextField has a method called (NSString *)stringValue - which returns a string of the value in the text bo
