Remoting is the process of programs or components interacting across certain boundaries. These contexts will normally resemble either different processes or machines.1 In the .NET Framework, this technology provides the foundation for distributed applications it simply replaces DCOM. Remoting implementations generally distinguish between remote objects and mobile objects. The former provide the ability to execute methods on remote servers, passing parameters and receiving return values. The remote object will always stay at the server, and only a reference to it will be passed around among other machines. When mobile objects pass a context boundary, they are serialized (marshaled) into a general representation either a binary or a human readable format like XML and then deserialized in the other context involved in the process. Server and client both hold copies of the same object. Methods executed on those copies of the object will always be carried out in the local context, and no message will travel back to the machine from which the object originated. In fact, after serialization and deserialization, the copied objects are indistinguishable from regular local objects, and there is also no distinction between a server object and a client object.

Included within the new release of ASP.NET 2.0 are several web controls that are available out of the box to easily create site navigation. Because all websites should provide a professional layout of navigation, each of the three controls the SiteMapPath, Treeview, and Menu will be able to accomplish that goal. However, with that said, in different scenarios one control will have a better fit than another. For instance, if the information or data within your web application has many nested values, you might consider using the Treeview control because of how it can collapse and uncollapse those nested values. If your application needs to leave a trail to indicate where the user has been, the Menu control would probably be the best fit. To break down the similarities and differences further and help you decide which control offers the best fit for your scenario according to the examples just described, examine Table 7-1. Table 7-1.

1. Ensure that SQL Server a Query Editor pane is running and that there is an empty Query Editor pane. First of all, let s get the T-SQL correct. We need to link in three tables, the CustomerDetails.Customers table to get the name and address, the TransactionDetails.Transactions table so we can get a list of transactions for the customer, and finally the TransactionDetails.TransactionTypes table so that each transaction type has its full description. The code is as follows: SELECT c.AccountNumber,c.CustomerFirstName,c.CustomerOtherInitials, tt.TransactionDescription,t.DateEntered,t.Amount,t.ReferenceDetails FROM CustomerDetails.Customers c JOIN TransactionDetails.Transactions t ON t.CustomerId = c.CustomerId JOIN TransactionDetails.TransactionTypes tt ON tt.TransactionTypeId = t.TransactionType ORDER BY c.AccountNumber ASC, t.DateEntered DESC 2. Once done, execute the code by pressing F5 or Ctrl+E, or clicking the execute button.

imgWeather.Source = new BitmapImage(new Uri(evt.EventArgs.Result.Details[0].WeatherImage, UriKind.Absolute)); } }, ex => { Deployment.Current.Dispatcher.BeginInvoke(() => lblStatus.Text = ex.Message); } ); Note the somewhat cryptic (it s a lamda expression and it uses a lambda expression within its own body) use of the Deployment.Current.Dispatcher.BeginInvoke statement to get around cross-thread access issues discussed previously. In the preceding code, the OnError handler simply displays the exception text, but there is nothing stopping you from dissecting an error thoroughly and providing a possible corrective action. For instance, if the web service is not available at the address specified, you may retry your call to a different location of the web service. Rx.NET also has exception handling operators Catch, Finally, OnErrorResumeNext, and Retry, which aid in recovering from errors. You will explore some of those in the next section as we discuss some potential ways of handling intermittently available data connections on the phones.

<shell:ApplicationBarIconButton Text="Save Photo" IconUri="images/appbar.save.rest.png" Click="btnSave_Click"/> You are now ready to run the application on the Windows Phone 7 emulator. Press F5 to start the application, and then press the Camera button on the Application Bar (first button) to take a picture and have it loaded inside your application. Then, press the Save button on the Application Bar you should get a status message that the image was successfully saved. Now, if you use the middle button of the Application Bar to see photos available, you should see a screen like the one shown in Figure 16 2, with three separate photo folders, each displayed in a separate tile available to choose photos from.

To run the FlexUnit tests, Flash builder 4 and SDK added FlexUnit to the menu under the launch and debug icon, as shown in Figure 1-18. Select launch icon Execute FlexUnit Tests.

Apple offers many programs to hardware and software developers who want to leverage their ideas using products such as iPhones, iPods, Macintosh computers, Mac OS X, and Safari. The Mac Developer, iPhone Developer, and Safari Developer programs focus on the software aspects of their respective underlying platforms. Each program provides several levels of membership that offer varying degrees of benefits. Obviously, the higher the benefit, the more the cost of membership. All three programs can be viewed as subclasses of the Apple Developer Connection membership. The ADC provides a resource umbrella from which you can manage your assets of any and all program memberships. The Made For iPod/Works With iPhone program, like all other Apple developer programs, comes with strict non-disclosure agreements which participants must agree to and sign. Violation of the NDA from any program can have serious consequences including termination of your membership in any and all programs. Because of NDA agreements, I am unable to provide details in order to help you choose whether or not you should participate in the MFi/WWi program. However, Apple is a business, like any other technology corporation, and is in this for profit. As such, by adopting and following sound business practices that any successful technology firm adheres to, a prospective participant should be able to understand what is in store for them should they choose to participate.

AIR 2.0 adds the ability to support IPv6 to all network APIs. Currently, the Internet mostly uses IP version four (IPv4), an address format that is 20 years old. IPv4 uses a 32-bit architecture and is limited in the 32 available address space to 4,294,967,296 or 2 unique IP addresses. Since many devices are consuming IP addresses, IPv6 was created to ensure that you do not run out of IP addresses. IPv6 is not as common as IPv4, and it is currently being used in some tests and early adopter networks. However, it is important to be able to access the IPv6 for networks that are using these IP addresses, and it will only become more common in future.
