By subclassing BusinessBase, all these objects gain the full set of business object capabilities implemented in s 3 through 5. The model also includes objects that are collections of business objects, and they should inherit from BusinessListBase, as shown in Figure 6-12.

COM+ 1.5 and higher allows you to provide separate configuration files (essentially like app.config or web.config) for each COM+ application. This is an important feature available on Windows XP and Windows Server 2003 (and higher), because without it you could only provide one configuration file for all COM+-hosted .NET code. To use this feature, you need to create two files for your Enterprise Services assembly: application.config application.manifest The application.config file is actually named application.config. It is a standard .NET config file that contains the normal .NET configuration that you would put into any app.config file, including the CSLA .NET configuration settings. For instance, it might look like this: < xml version="1.0" encoding="utf-8" > <configuration> <appSettings> <add key="CslaAuthentication" value="Csla"/> </appSettings> </configuration>

When creating a test cloud storage table, any active SQL query analysis running against the existing cloud storage table needs to be closed from SQL Management Studio to avoid the failure of data storage creation.

The AtlasUIGlitz library is a nice add-on library that provides a number of UI behaviors that you can use to make your user interfaces more attractive and, well, glitzy. The library offers two behaviors that you can manipulate: opacity and layout. The former, opacity, allows you to set the alpha level of transparency/opacity of your page elements. You can create whizzy user interfaces that make the most of modern graphics cards and browsers to render complex UIs that have controls overlaid on each other, with the hidden controls visible through slight transparency on the overlaying controls, allowing the user to look through them. The latter, layout, allows you to easily and explicitly place controls on the page. It allows you to set the top, left, height, and width properties of an element through properties of the behavior. This gives you fine-grained control over how your interface is laid out. In addition, the AtlasUIGlitz library offers a number of animation effects that can be applied to controls on your page: The fade animation allows you to fade the opacity of a control in or out. You can use this to smoothly make controls appear or disappear or to provide a nice visual indicator of inactive controls by smoothly making them more transparent. Length animations allow you to map a range of numbers to a control s property where the framework automatically drives the value of the property from the start value to the end value and appends a text unit to the end, such as px allowing you to specify image, table, or other element s width and height properties through an animated range.

The SortedDictionary<TKey, TVal> collection is just like the regular Dictionary<TKey, TVal>, except that the key/value pairs are sorted based on the key. Listing 19-24 compares the two kinds of collection. Listing 19-24. Comparing Dictionary<TKey, TVal> and SortedDictionary<TKey, TVal> using System; using System.Collections.Generic; namespace Listing 24 { class Listing 24 { static void Main(string[] args) { // create the Dictionary instance Dictionary<string, string> dict = new Dictionary<string, string>() { { "apple", "green" }, { "cherry", "red" }, { "mango", "green"}, { "banana", "yellow" }, { "strawberry", "red" } }; // enumerate the contents of the Dictionary Console.WriteLine("Enumerating Dictionary"); foreach (KeyValuePair<string, string> kvp in dict) { Console.WriteLine("Dictionary Key: {0}, Value: {1}", kvp.Key, kvp.Value); } // create the SortedDictionary SortedDictionary<string, string> sdict = new SortedDictionary<string, string>(dict);
