Managed C++ Example Code

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++)

 

using namespace System;

using namespace Netica;

 

int main (array<String ^> ^args)

{

Console::WriteLine ("Welcome to Netica API for Managed C++ !");

 

Netica::Application^ app = gcnew Netica::Application;

app->Visible = true;

String^ net_file_name = AppDomain::CurrentDomain->BaseDirectory + "..\\ChestClinic.dne";

 

Streamer^ file = app->NewStream (net_file_name, nullptr);

BNet^ net = app->ReadBNet (file, "");

net->Compile();

 

BNode^ TB = net->Nodes->Item ["Tuberculosis"];

double bel = TB->GetBelief ("present");

Console::WriteLine ("The probability of tuberculosis is " + bel);

 

BNode^ XRay = net->Nodes->Item ["XRay"];

XRay->EnterFinding ("abnormal");

bel = TB->GetBelief ("present");

Console::WriteLine ("Given an abnormal X-Ray, the probability of tuberculosis is " + bel);

 

net->Nodes->Item["Cancer"]->EnterFinding("present");

bel = TB->GetBelief ("present");

Console::WriteLine ("Given abnormal X-Ray, Asia visit, and lung cancer, the probability of TB is " + bel);

 

net->Delete();

if (!app->UserControl) app->Quit();

 

Console::WriteLine ("Press <enter> to quit.");

Console::ReadLine();

 

return 0;
