MFC Scribble - SDK sample

The MFC Scribble sample extends the standard MFC Scribble sample with the generation of PDF files and by using the novaPDF SDK application. It demonstrates how to integrate novaPDF SDK in your documents and also view the MFC architecture.

Note: To be able to use the samples you must install novaPDF SDK as samples work only with it. Download it here: nova PDF SDK.
