Quick Start: Retrieving PDF document properties using the web service API

The following code example determines whether the document is a PDF document and, if so, the earliest Acrobat version able to read it.

/*

 * Ensure that you create a .NET client assembly that uses 

 * base64 encoding. This is required to populate a BLOB 

 * object with data or retrieve data from a BLOB object.

 * 

 * For information, see "Invoking LiveCycle ES using Base64 Encoding" 

 * in Programming with LiveCycle ES
