Use this method to output HTML tags in the form <INPUT TYPE="HIDDEN"> in an HTML form. These hidden fields contain specified values from the OrderForm object to be used to verify that an order has not been altered between presentation of the OrderForm and final purchase. When the order form is submitted, the ProcessVerifyWith method on the target page stores these fields in a Dictionary object in the OrderForm, which is then passed to the Order Processing pipeline (OPP). One of the objects in the pipeline compares the original values with the values from the hidden fields.

Important

This method is included for backwards compatibility with Site Server 3.0 Commerce Edition. See the AppFrameWork object, which provides similar functionality to that found in this method. Using the AppFrameWork methods is the preferred way of adding this type of functionality to your site, and will ensure better compatibility with future versions of Microsoft Commerce Server.
