SOFTWARE -> YOUR APPLICATION
It is quite simple to create your own application, that can communicate to HAPCAN system. You can find here examples written in C++ language by using C++ Builder development environment of Borland. These examples are to help to create application, that suits user needs. All source codes are free of charge and given under MIT license, that gives rights to use, copy, modify, merge, publish and distribute.
Development environment
Example software has been written in C++ Builder Personal 6 of Borland. Full version of this development environment was distributed on CDs with IT magazines.
Programs
To test example programs you can use HAPCAN demo system. The IP number of the demo system is dynamic. Actual one can be checked on this page by typing hapcan.no-ip.org address. The port number is 80.

EXAMPLE 3
This program can control and monitor status of two modules dimmer and relay. It is easy to extend number of controlled devices. If status of any module changes, the program will display it immediately. By clicking on module symbol, it is possible to control device.
