A set of controls to build LCARS computer systems.

Sample Image - lcars_net_controls.gif

Introduction

To be honest, Star Trek is one of the main reasons why I love technology. Since I was a child, I dreamed about these ships and its talking computers.

Today, in several Star Trek related websites, we can see the look and feel of the ship's computers, named LCARS (Library Computer Access and Retrieval System). But in all of them, the interfaces were developed in Flash or HTML. Searching on the internet, I couldn't find any components for other platforms.

Thinking about that, I developed a simple set of LCARS controls for the Microsoft .NET framework 1.1.

Background

The components included in the "LCARS_Toolbox.DLL" assembly are:

  • LCARS_Elbo: Elbo is the component that splits the screen in different zones.
  • LCARS_Panel: Panel is a single colored rectangle. This component could be finished by round corners.
  • LCARS_Label: Label is a rectangle with a single text on it.
  • LCARS_Button: Button is the component to execute actions and interact with the user.
  • LCARS_Sound: Sound is the component to play sounds. Only plays WAV files. Some cool sounds can be downloaded here.
  • LCARS_Date: Date is the component to display "StarDate" dates. Also offers a regular date display.

Notes

All the design, like colors and components, were based on the information available in http://www.lcarsdeveloper.com/.

All the components that uses text requires the LCARS font that can be downloaded here.

The code to generate StarDate dates was based over the free JavaScript source code available from http://www.javascriptkit.com/script/script2/stardates.shtml.

Using the Code

All the properties required are grouped in the "LCARS" category.

To build a LCARS terminal, you must drag and drop the different controls over the form and adjust them using your own style (all the design is visual). Then, you can add some interaction like sounds and clicks.

Sounds

To add sounds, you must drag a LCARS_Sound component. Then, you must add some code. There are three ways to play a sound:

  • PlayOnce (soundName): In this case, the sound is played only once, with no waits.
  • PlayOnce (soundName, wait): In this case, the sound is played only once, but waits for the sound to terminate.
  • PlayLoop (soundName): In this case, the sound is played continuously in a loop, like background sounds. To stop a looped sound, you can use the "Stop" method.

Important: Because the sounds are played using threads, if you are using a background sound, be sure to stop it before to close the application.

Clicks

To add some click actions, you must drag a LCARS_Button component. Then, you must implement the "OnClick" event in the usual way.

C#
void LCARS_Button5Click(object sender, System.EventArgs e)
{
    if (lCARS_Button5.Blink) {
        lCARS_Sound1.Stop();
        lCARS_Button5.Caption = "SOUND ON";
        lCARS_Button5.Blink = false;
        lCARS_Button5.BaseColor = lCARS_Button2.BaseColor;
    } else {
        lCARS_Sound1.PlayLoop("212.wav");
        lCARS_Button5.Caption = "SOUND OFF";
        lCARS_Button5.Blink = true;
        lCARS_Button5.BaseColor = "330000";
    }
}

The LCARS_Button also includes some cool properties like the internal optional sound (SoundFile), the text property (Caption), and the blink feature (Blink).

Points of Interest

In the included sample, you will see a simple LCARS terminal that shows an image viewer with sounds. To compile, execute the c.bat file. Don't forget to install the LCARS font.

If you are a Star Trek fan, I hope that you enjoy this control and builds really awesome 24th century systems.

Hi! I'm interested in this piece of code too. Can you send me the decompiled source, so that I can get into it and -possibly-! solve the issue?

Thank you!
