Code Sample for Word to PDF Conversion
The code below was taken from the Word to PDF demo application available for download in the Word to PDF Converter archive. In this example an instance of the WordToPdfConverter class is constructed and used to convert an Word file to a PDF document in a memory buffer. The resulted buffer is saved in a PDF file on disk. The demo also contains code for adding a header and a footer with page numbering to the resulted PDF document.
