The code in this book can be copied into a Notepad document and saved as the  following file: Alternatively, download the sample file that is associated with this book as a  downloadable material.  Place the sample file in the following folder:  When the complaint form was developed, we specifically placed our bar codes in  a location next to the signature zone. This was done to enable their location to be  captured and used as anchors to determine our signature zone. When bar code detection runs, it creates several page-level variables holding the  bar code locations. By using these values, we can dynamically locate our  signature even if the size of the form changes. Figure 9-43 depicts how this works:  Chapter 9.
