NSFullUserName() always returns the user name at app launch?

I'm using NSFullUserName() to get the user name of the currently logged user and from my application, the user can open the Accounts preference pane to edit it. Problem is, after the user changes his user name, another call to NSFullUserName() still returns the original user name. Is this a bug

Scope of NSOperations

My (Leopard) app needs to create a sequence of NSOperations, often thousands of them, a few at a time. The relevant code is in a setup function that ends with for (k = 0;k < numOps;k++) { solverOp *thisOp = [solverOp new]; [thisOp initWithData:Data]; [opQueue addOperation:thisOp]; } at

Determining the name of a method's caller

It seems like he's saying that the name change doesn't take full effect until the user logs out and logs back in. For example, my FullUserName() is "Dave DeLong". If I change it to "Zaphod Beeblebrox", that won't take effect until I log out and log back in, because my current user session is f

windowWillResize: where does the 64 pixel limit come from?

When I am resizing my window, I have a delegate method windowWillResize:toSize: which is being called. What I am finding odd is that the width of the size being passed in will never go below 64 pixels even if the width for contentMinSize and minSize is less then 64 pixels. I can easily force the

I can't say that I have dealt with the exact situation you write of, however, my best idea/hint is to point you to the NSTextContainer class. The NSTextView is composed of a lot of complicated machinery and I believe you might have to dive below the topmost layer (i.e. NSTextView itself) in ord

Implementing NSOutlineView datasource methods when using an asynchronous source?

If I understand your question, maybe you just need to do some initialization when the object is created. Look at NSManagedObject:awakeFromInsert. It's where you can do initialization (conditional if you wish, as long as you don't do something to disrupt the "insertion" process). It's perfectl
