Ah ha!, thanks so much Traian, that explains it better. I think you've kicked me onto the right path!
Thanks again.

If it is a string, the decoded byte array is a utf8 string with a null terminator. So you have to look at it as an array of bytes, and not a number. If I take the integer 892744497 and convert to hex using little endian, I get the bytes { 0x31, 0x33, 0x36, 0x35 }. If I look at this as an array of characters, it corresponds to { '1', '3', '6', '5'}. Does that look familiar?

However, when I attempt to decode a UID that is NOT made up a single integer field, I'm running into some problems: Scenario #1: If the UID consists of 2 integer fields, upon decoding, only the first value is returned. Example, objects Key fields are: UID1: value=1684 UID2: value=1365 When I decode this, only the first value, 1684, is returned. Do I need to do something different for decoding a feature where there are multiple key fields? Scenario #2 If the UID consists of a text field, the decoded value is incorrect. Example, object UID = '1365-1684' Decoded, the returned value is: 892744497 And I noticed if multiple objects are selected, it seems all of the decoded values are: 892744497 Any comments, ideas, suggestions would be greatly appreciated.
