Below is an example Managed C++ (i.e., "C++/CLI") program that does the same thing as the "Demo" program that ships with Netica C-API. There is a Visual Studio project for it, called "Netica Demo for CLR C++" within the " Netica\Netica xxx\Programming Examples " folder of the Netica download package. (more info on programming Netica in Managed C++)
