(Unicode C) HTTPS MWS List Orders (Amazon Marketplace Web Service)

Send an HTTPS MWS ListOrders request to return a list of orders created or updated during a time frame.

Note: This example requires Chilkat v9.5.0.66 or greater.

Important: The Chilkat v9.5.0.75 release accidentally breaks Amazon MWS (not AWS) authentication. If you need MWS with 9.5.0.75, send email to support@chilkatsoft.com for a hotfix, or revert back to v9.5.0.73, or update to a version after 9.5.0.75.
