In the NewtonSDK are some very good tutorials and belonging to them some samples in C++ - Code. Because I´m naturally a Delphi/Pascal - Coder, and at the moment learning to use Newton, you are able to download the Code to every tutorial one after another. My demos are, in opposite to the ones in the SDK more minimalistic, `cause they should only referr to the theme dealt with in the several tutorials.
You need the recent Version of the Newton.DLL - Library for each Download!
1. Tutorial - Getting Started
2. Tutorial - Using Callbacks
