[[NSUserDefaults standardUserDefaults] setObject:myArray forKey:@"myArray"]; If I make an array of custom objects conform to the NSCoding protocol, then does the above work?

Hi there, I'm looking for any alternatives to the below for creating a JavaScript array containing 1 through to N where N is only known at runtime. var foo = []; for (var i = 1; i <= N; i++) { foo.push(i); } To me it feels like there should be a way of doing this without the loop. Cheers for any ideas. ...

This throws an out of memory exception when using 10^8 items but not with 10^7. How would you serialize an array with 10^9 values in it so that it could be stored in a database? Dim List((10 ^ 9) - 1) As Int64 For i = 1 To (10 ^ 9) List(i - 1) = i Next Dim Format As New Runtime.Serialization.Formatters.Binary.BinaryFormatter Dim Wr...

Update: False alarm! The source of the error was elsewhere. (See at the end of the question.) Is it possible that either Linq or foreach can mess up the order of an array? One of my testers reported to have experienced that the order of a list of items he fed in as input didn't match the order of the final list that was saved in the da...
Hi I have this code, what am I doing wrong? I have a function which I call playing a number of strings into an array. Then at some point I want to reload it after the user has edited the strings.
