There is no such method on 10.5 so in your case you would have to do everything at the NSView level by implementing the NSDraggingDestination protocol. So basically you'd have to - subclass the IKImageBrowserView - implement the needed methods from NSDraggingDestination (draggingEntered, dragging

Detect HFS path type and coerce to POSIX

My app receives both HFS and POSIX NSString file paths back from AppleScript. On the AS Implementors list I was advised to coerce all the AS data to say HFS before it is converted to an NSString. This will be my goal but in the short term I will need to detect HFS paths and convert them to POSI

Well, I have no experience of this API, but perhaps it's designed to do this so that when you restart a stream, you get an event that gives you a snapshot or starting point for the new session. Seems to me it would be trivial to compare the event ID and if it's the one you just passed in, ignor

I use NAN for things like this. (Not A Number ) if( !sound ) return NAN; and your test would then be if( isnan( sound ) ) return nil; provided you aren't doing any divisions by zero similar things in your code which could cause the value to be NaN, it's a useful marker for "I d
