Win32ole object collection mapping to array?

Hello all,

I have a win32ole object collection that I want to map, then sort, to an
array?

Each item has #Name property. I'm thinking of making an arry of hashes
a'la :

items =
oleItems.each {|o| items << {o.Name => o} }
items

[{"0172"=>#<WIN32OLE:0x2a88570>}, {"0171"=>#<WIN32OLE:0x2a88540>}]

But then, how do I sort the array of hashes ?

Is there a better approach ?

Not sure why you'd want an array of hashes, but here goes:

items.sort_by {|h| h.keys[0].to_i}

Maybe I misunderstood. Are planning on later adding multiple objects
with the same Name? Then, you might consider a hash of arrays.

Anyways, why not just make it a simple hash?

hash = {}
oleItems.each {|i| hash[i.Name] = i}
# when you want them in a sorted array
hash.values.sort_by {|v| v.Name.to_i}

Perhaps I need to know more about the context of your code.

Try this...

items =
oleItems.each {|o| items << {o.Name => o} }
items.sort {|x, y| x.Name <=> y.Name}

You can try this (apologies if i misunderstood you problem):

oleitems.map{|o| o.Name}.sort

This makes an array of Name values, then sorts it. I couldn't understand if
you want values as an array or hash.

Sorry. What I gave you is wrong. Daniel has a good solution.
