Hi,
I have never heard of a sort string array function that's native to Access.
In any case, here's what I do in these situations.
Fire up Google, enter:
"visual basic" sort string array
as your search criteria and here's one of the hits you come up with: http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=821&lngWId=-1
it looks complicated but all you have to do is copy and paste.
It even shows a sample usage (how to call it)
