DELPHI (win32)

In the second stage the time for pc application has come. Delphi is the object-

oriented programming language based on Pascal. Version I have used was the 2009

Professional trial that allows to test all means necessary for the project. Before the

beginning I have received permission from the official Embarcadero distributor in Poland

to use trial version in this project.

1. Operating Principle

WCC application has two tasks: one, to control servo and the BlackBox and

two, to manage WCS settings that allows to connect to the wireless network. To

achieve them we can not forget about appropriate level of security.

Operating principle is very simple. At the beginning user needs to log in. After

positive verification of the username and password application tries to connect

via telnet protocol with WCS (IP address is written in external setup.ini file). If

connection was successful, control and settings options are available.

2. Components

IdTelnet  responsible for handling telnet protocol.

MainMenu  simple menu creation.

3. GUI (Graphical User Interface)

Graphical Interface is a standard one built

with components provided by Delphi.

Nothing extraordinary was adopted in this

matter. Simple menu with Login, Servo

and Settings pages is clear for the user as

befits engineering software design not to

please eye but to control determined

process.
