44.8.1.1 .NET Embedding

If you have an advanced Prolog application that needs a GUI you can write a stand-alone .NET application that handles the GUI and set up the Prolog server to call the right predicates in the Prolog application.

An example of how to do this can be found under the pbnetexamples('evaluate.NET') directory. This example is the C# version of the example shown in PB First Example).

To start the example, first start the Prolog server by going to the pbnetexamples('evaluate.NET') directory and type:

     > sicstus -l evaluate.pl --goal "main."

To start the GUI type (from the same directory as above):

     > run.bat

Another example of this is pbnetexamples('pbtest.NET'), which illustrates several advanced features like:

• registering several queries
• listening to server events (server_started)
• shutting down the Prolog server from .NET
• starting up the Prolog server from .NET
• using dynamic (OS assigned) ports for the .NET/Prolog communication

The example is run by executing the C# program PBTest:

     > PBTest
