Quick Start (Base64): 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. (See Retrieving PDF Document Properties.)

    * 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 using Base64 Encoding"  
    * in Programming with LiveCycle
