software for decisions with microsoft visual c++

[amuizzc]

Hi I'm Antonio,
i've just created a software in microsoft visual c++ 2005 for decisions with a series of if-then-else.
Now i wanna substitute this kind of decisions system with a bayesian network using hugin.
How i can do it? How i can use Hugin with microsoft visual c++ (2005 or 2008 doesen't matter)?
Have you some code examples to do this? Some guides or tutorials?
Thank you very much
Regards
Antonio

How i can use Hugin with microsoft visual c++ (2005 or 2008 doesen't matter)?

The Hugin C++ API provides files for both VS2005 and VS2008 (located in <hugin-install-dir>\VC8 for VS2005 and \VC9 for VS2008). For instructions on how to set up a C++ project with Hugin in Visual Studio please refer to the API Manual (pdf-file) section 1.3 "Using the HUGIN API on Windows Platforms".

Have you some code examples to do this? Some guides or tutorials?

The C++ API Documentation contains a number of examples.

Hi Martin,
first, thanks for the response!
Then, i've implemented my bn with hugin, i've posted for you my file here: http://digilander.libero.it/thuglupin/BN.rar

Now i wanna manage my net with visual c++ 2008 e.d. in the sense that i wanna create a windows form with 4 combobox where can choose the states of Categoria_Utente, Conoscenza_Utente, Posizione_Utente, Azione_Utente.
Successively to the choice, i wanna display in a box (doesen't matter what kind), the states chosen by the BN for Attitudine_Affettiva, Goal, Attitudine_Sociale.
But i don't know how to manage the BN with visual c++ 2008 e.d.
Help me please!
Thank you very very much!
Antonio

For Visual Studio 2008 you should use the library files in <hugin-install-dir>\HDE7.1CPP\Lib\VC9.

The API reference manual contains information on the steps needed to to set up Visual Studio for using the Hugin APIs. (See section 1.3 Using the HUGIN API on Windows Platforms).

You can also take a look at the C++ test code in <hugin-install-dir>\Test.
The Hugin C++ Doxygen documentation contains a number of C++ examples with code.

Here is a list of Hugin C++ functions I think you will need for this solution - you should check them out in the documentation as well:

Getting nodes and states:
HAPI::NetworkModel::getNodes
HAPI::DiscreteNode::getNumberOfStates
HAPI::DiscreteNode::getStateLabel

Entering evidence:
HAPI::DiscreteNode::selectState

Reading beliefs:
HAPI::DiscreteNode::getBelief

thanks a lot Martin,
but i've some problems: the API reference manual contains information on the steps needed to to set up Visual Studio for using the Hugin APIs, but the one i've is only for c# and not for visual c++, have you the link where i can find it? then where i can find The Hugin C++ Doxygen documentation? and what's Hugin C++ Doxygen?
Thanks
Antonio A.

The C++ documentation can be found here:
<hugin-install-dir>\HDE7.1CPP\Doc\index.html
and by clicking through the Windows Start menu:
Start -> Programs -> Hugin 7.1 - > Hugin C++ API 7.1 Help

The Hugin API reference manual:
<hugin-install-dir>\HDE7.1C\Doc\api-manual.pdf
Or from start menu:
Start -> Programs -> Hugin 7.1 - > Hugin C API 7.1 Help

If you read a little further in the Hugin API reference manual (the PDF file) from section 1.3 "Using the HUGIN API on Windows platforms" you will find information on setting up C++ environment in visual studio.

Doxygen is a tool that generates documentation based on C++ code. We have used it to genete documentation for the classes in the Hugin C++ API.
