NSDeviceResolution does not give you an NSString. It gives you an NSValue respresenting an NSSize. Try this: NSValue* v = [dd valueForKey:NSDeviceResolution]; NSSize sz = [v sizeValue]; (The error message gives you a hint: NSConcreteValue is one of the implementations of NSValue.) -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
