The web interface provided by the example program is functional, but not very pretty. With a little bit of work it s possible to create a web interface that is more visually appealing by replacing the contents of the sendWebPage() function. Even without the use of images it s possible to fake a graphical display using colored table cells. For example, the alternative version of the sendWebPage() function shown next will display a visual representation of how much water is in the tank. boolean sendWebPage(char* URL) { sensorValue = constrain( analogRead( TANK_SENSOR ), TANK_EMPTY, TANK_FULL ); tankLevel = map(sensorValue, TANK_EMPTY, TANK_FULL, 0, 100); if (strcmp(URL, "/") == 0) { WiServer.print("<html><center>"); WiServer.print("<h1>Tank Level</h1>"); WiServer.print("<h2>"); WiServer.print(tankLevel); WiServer.print("%"); WiServer.print("</h2>"); WiServer.print("<table width=200 cellspacing=0 cellpadding=0 border=1>"); WiServer.print("<tr><td bgcolor=#cccccc height="); WiServer.print(2 * (100 - tankLevel)); WiServer.print("></td></tr>"); WiServer.print("<tr><td bgcolor=#3333aa height="); WiServer.print(2 * tankLevel); WiServer.print("></td></tr>"); WiServer.print("</table><br><br>"); WiServer.print(sensorValue); WiServer.print("</center></html>");

Before you begin these steps, you have one very important decision to make. Will you expose an entire managed class to COM, or do you want to define your own interface Since COM is all about interface-based component development, the preferred approach is to define your own interface, which is covered in a subsequent recipe. But .NET also supports exposing an entire class to COM. This recipe demonstrates the simplest way to expose managed classes to COM, using a class interface that is automatically generated for you.

return true; } return false; } The result is a display that shows blue in the bottom section for the water depth and grey above it for the empty part of the tank, along with the percentage value at the top and the literal reading underneath for calibration purposes (see Figure 12-17).

Note Please be aware that using a class interface to expose classes to COM has a number of major limitations that are discussed shortly. This is not the preferred way to expose a managed class to COM, but it is covered here since it is a workable solution. If you decide to use class interfaces to interoperate with COM, make sure you understand and manage the potential problems with this approach.

Figure 12-17. Visual display of tank level using colored table cells Because you can t store separate files inside the Arduino on a traditional filesystem like you can with a typical web server it s a bit more difficult to create a page that is really graphical, but with a few little tricks it can still be done. One approach is to embed the HTML inside the program on the Arduino and have it reference images stored on a totally separate server located somewhere else. Once you ve designed a graphical page that you want your Arduino to serve, you just upload all the images, CSS files, and other objects to a web host that you control and use absolute references in your HTML rather than relative references. All that means is that instead of referencing an image in your HTML like this: <img src="myBigImage.jpg"> you do it like this: <img src="http://www.example.com/myBigImage.jpg"> Using this technique you can even include Flash content, audio, video, and anything else you might want to put on a web page. Because the Arduino itself doesn t need to serve the files, you re only limited in terms of the size of the HTML you want to create and everything else comes from the external server.

As the name implies, a class interface is designed to expose an entire class to COM. This generated interface exposes all public fields, properties, methods, and events of the class. Any public fields are actually exposed as COM properties. For example, consider this class implemented in C#: using System; namespace DniNetSimpleNumbers { /// <summary> /// Managed class exposed to COM clients using /// the default class interface /// </summary> public class DniNetSimpleNumbersDisp { public int AddSomeNumbers(int numA, int numB) { return numA + numB; } } } This class is in a class library project named DniNetSimpleNumbers. On the surface, this is an unremarkable C# class. Without modifying the class at all, we can expose it to COM clients. To do this, we need to generate a typelib and register the assembly containing this class for COM interop. Visual Studio can perform these generation and registration duties, as long as you enable the correct options within the project properties. For a C# or Visual Basic .NET project, you can right-click the project in Solution Explorer and select Properties. Once there, you need to set both of the following options: On the Application tab, click the Assembly Information button. This opens a modal dialog. On the dialog, check the Make assembly COM-visible option. On the Build tab, check the Register for COM interop option. Enabling these options adds the ComVisible and Guid attributes to the AssemblyInfo.cs file for a C# project. For a VB.NET project the AssemblyInfo.vb file is updated.
