responds with the default page once again This check is not strictly necessary because if you only ever wanted your program to return the page with the sensor data on it, you won t care what arguments are passed through: you want your Arduino to always just respond with the same page However, we ve included it in this example because it demonstrates how you can create a crude navigation system and have your Arduino return different pages depending on what argument has been sent through In the example it does this by checking for a cmd value of 2, in which case it knows the user is specifically requesting the About page rather than the page with sensor data and makes a call to print_webpage_about() instead of print_webpage().

As demonstrated in this example structure, use of the MarshalAs attribute is not an all-or-nothing matter. You are free to mix and match the use of the attribute as needed, applying it only in cases where it is truly required. In the example, the ShortInteger field does not use the MarshalAs attribute; instead, it uses the default marshaling. Furthermore, we could simplify the example structure slightly if we want to totally rely upon default marshaling behavior. The default marshaling for a string is to an ANSI string, and the default for a Boolean is to a 4-byte integer (Win32 BOOL). Therefore, we can omit the MarshalAs attributes from those fields without any adverse affect. The revised structure could look like this: [StructLayout(LayoutKind.Sequential)] struct ManagedAmbiguousStruct { public string AnsiString; [MarshalAs(UnmanagedType.LPWStr)] public string public bool Win32Boolean; [MarshalAs(UnmanagedType.I1)] public bool public ushort ShortInteger; };

You could define a whole bunch of pages and store them in your program, then use identifiers to load different pages on demand Or alternatively you could modify the print_webpage() function so that it only returns the value from one sensor, and have it use a value submitted by the user to determine which sensor to process That way, you could connect to a URL such as http://192168115/ cmd=4, to access the data for sensor 4 Just remember the restriction on page size and don t try to create the next big CMS (content management system) on your Arduino! void loop(){ uint16_t plen, dat_p; int8_t cmd; plen = es.

Figure 3-10. Adding a new client To create a client, you need to give the client a name and, optionally, some notes. Then click the OK button to create the client. You can also assign permissions on a user-by-user basis; I ll discuss permissions in the next section of this chapter. Creating a department works very much like creating a client. There s a department listing page that looks like the client listing page, and a department edit page that looks like the client edit page. In fact, they re pretty much the same pages, with the exception of saying department instead of client everywhere.
