Custom sort field - custom message item

Hi,

I posted this in another OL group but get no reply.
I have code to parse a data from the body of an online enquiry
into the custom field, I just need a way to sort by that field
when viewing the items.

For example

myContact.UserProperties("ShoeSize").Value = parse( myItem.Body ,
"shoeSize=")

Now how I sort contacts by shoe size

Or even better, is there a way to sort the mail message by shoe size
and not even create the custom contact items.


Thanks.
