When I created the custom property set, I set the numberformat to "######". Thus, element 1 is actually named "000001". The unsorted list of the keys is not quite in alphanumeric order, because almost. When I put the unsorted list of the keys in the message box, key "500000" is indeed the last key.
I also tested this with putting the unusual item in element "300000", and it took like .75 seconds to return the result. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alex Tweedly Sent: Wednesday, March 02, 2005 5:58 PM To: How to use Revolution Subject: Re: custom property searching speed question Lynch, Jonathan wrote: >Anyway, I experimented with a customproperty set created to contain >500,000 elements - each element contains like 7 words.

So when you say "only the very last element contains ...", you need to be aware that they are not being looked at in the order you might think - i.e. the one containing that word may be looked at much earlier because of the hashing of the key values. So in your original problem statement, you said (something like) "and find the first one that contains" - "first" has a fairly loose meaning in the context of an array .... if order is crucial to you, you may need to take the keys of the array, sort that, and then access the elements by lookup - this will be much, much slower. -- Alex Tweedly http://www.tweedly.net -- No virus found in this outgoing message.
