Let's say we have a hash:
flash = {}
flash[:error] = "This is an error."
flash[:info] = "This is an information."
I would like to convert it to a string:
"<div class='error'>This is an error.</div><div class='info'>This is an information".
in nice one liner ;)
I found something like that:
flash.to_a.collect{|item| "<div class='#{...

int[] i = {3, 2, 1};

In other languages I could create a class then use this to create an array of objects in that class eg class price which is used in a performance class to define a price[] prices;

The price class is an inherit of NSObject, can I use NSMutableArray?

For C++ gurus: Can you please elaborate why this code crashes at the places mentioned? I am a bit stumped on this. I guess that it has got something to do with sizeof(int) but I am not so sure. Can anybody explain?

How can I convert a BYTE buffer (from 0 to 255) to a float buffer (from 0.0 to 1.0)? Of course there should be a relation between the two values, eg: 0 in byte buffer will be .0.f in float buffer, 128 in byte buffer will be .5f in float buffer, 255 in byte buffer will be 1.f in float buffer.
Actually this is the code that I have:

In short, I am wondering if there is an auto_ptr like type for arrays. I know I could roll my own, I'm just making sure that there isn't already something out there.
I know about vectors as well. however I don't think I can use them. I am using several of the Windows APIs/SDKs such as the Windows Media SDK, Direct Show API which in or...
What would i need to put in the SortIP function to make the custom sort function sort the array by the last digit of the IP number. This doesn't work.

I have a Array of Characters objects (extends Sprite).
public static var charlist:Array;
When a Character die, I set a flag to indicate that.
char.die = true;
When I spawn a new player, I check against this flag, to reuse the slot. This is where the problem comes.
What is the best way to do that? Actually I have this approach:

I have an arbitrary method in Ruby that yields multiple values so it can be handed to a block:
def arbitrary
yield 1
yield 2
yield 3

end
