Simple question about changing a value of an object in a collection

I have this code

class Foo

Structure b
    dim id as integer
    dim name as string
end structure

private coll as new collection

pubic sub SetName (name as string, idKey as integer)
   dim tmpB as b

   tmpB = coll(idKey)
   tmpB.name = name

end sub



Assuming that the collection already as a bunch of "b" structures in it and I want to change the name variable, the SetName function doesn't work. It pulls the correct struct out based on the id key but the name doesn't permenantly change. How do you make the data save back in the collection?

Or is there a better way to do this?

Thanks,
Rut

Structures are value-types, as opposed to reference.  To keep using a structure, you'd have to remove the original and add the modified value back to the collection much like you would an integer value.  Or if you used a class instead of a structure, your example would work.
