Now that the user has a breakdown of the cost, they can use the Back button on the mobile device to make changes, or they can select the Buy link, which will take them to the next page, which handles the processing of the order (purchase3.aspx). Creating the Purchase Page: purchase3.aspx You can find the files for the purchase page at www.syngress.com/solutions (see purchase3.aspx, and purchase3.aspx.vb). Earlier in the chapter, we discussed how to simulate the login process; similarly, you can also make this generalization with regards to purchase.You can handle collecting of funds in a multitude of ways: third-party merchant services, in-house processing with appropriate infrastructure, online Wallets, even billing the cell phone account directly. (Nokia offers this on some models, mobile purchases are reflected on the cell phone monthly bill.) Your application assumes that this part is taken care of and generate a “Transaction key” to simulate the completion of the transaction.The Transaction key is what is used to grant theater access to the user.The Logic for this is encapsu- lated in the dataAccess component’s buyTickets method and the buyTickets stored procedure. Figure 8.23 consists of several text controls and a link to the home page.

This is your stub for a third-party vendor electronic funds transfer component tie-in. It will simulate billing the customer and will return a mock authorization key: Dim transkey As String = dso.buyTickets(eventid, customerid, count) TextView1.Text = "Thank you for your purchase!" & " your transaction key is:" TextView2.Font.Bold = BooleanOption.True TextView2.Font.Name = "arial" TextView2.Text = transkey TextView3.Text = "bookmark this page." End Sub This page will display a message including the newly generated transaction key. It will also display the message,“bookmark this page.” For a mobile phone, bookmarking the page will store it and enable it to easily be retrieved later.The following section examines how each of the emulators displays your mobile application. www.syngress.com Figure 8.23 Continued 175_NETmobile_08.qxd 12/28/01 1:45 PM Page 368 Creating a Mobile Movie Ticket Purchasing Application • Chapter 8 369 The Story Board This section contains a walkthrough of the application UI for each of the emula- tors we tested with. For the most part, the UI is the same. However, some of the smaller interfaces create more need to scroll. Interestingly, the Nokia emulator intersperses more platform-specific screens than the other emulators.

Simply copy Web from the solutions explorer window and input the information to the remote server you are to upload to.You can transfer files with FrontPage server extensions, or you can FTP directly.The Web directory must have a bin folder and the DLL must be inside. www.syngress.com Figure 8.120 The Web.config File 175_NETmobile_08.qxd 12/28/01 1:45 PM Page 388 Creating a Mobile Movie Ticket Purchasing Application • Chapter 8 389 Summary In this chapter, we stated the target devices your application would support and gave you links to obtain their emulators.We explained code design tradeoffs that were necessary to realize this goal: single form pages, avoidance of the ObjectList control, and configuring the site to run without cookies.You developed a scalable process that employs a relatively simple schema and a data access component for all database interactions, with built-in transaction handling through SQL stored procedures.You also stubbed out and simulated interfaces to third-party services, such as online wallets and passport style authentication, while providing insight into the effective use of mobile Web forms to render the UI on various device emulators.We focused on the following Mobile Web Form controls:  Mobile:Label  Mobile:TextView  Mobile:List  Mobile:Call We also demonstrated the following:  Setting control properties directly in their element attributes as well as through using the object model in code-behind pages.  Accessing data from static XML files to accessing data from SQL stored procedures.  Binding the List control to a DataSet and setting and updating the prop- erties of the generated code.  How different devices handle the same display information. Although this case study is rather simple, you should note that developing this type of system as a real-life application would require substantial investment on the customer’s part, in financial and process reorganization, as well as legwork in set- ting up online wallet, authentication, and bank/merchant transaction processing. Hosting the site from a central location that has access to all local theaters’ data might also make sense. www.syngress.com 175_NETmobile_08.qxd 12/28/01 1:45 PM Page 389 390 Chapter 8 • Creating a Mobile Movie Ticket Purchasing Application Solutions Fast Track System Design/Flow ; Identify and diagram the scenario you need to support, using flow charts to assist in the conceptual design of the database schema as well as candidate stored procedures. ; Storyboard the process so that all steps and screens can be laid out and evaluated before building the solution. The Data ; Creating stored procedures is the best solution for performance as opposed to ad hoc queries. ; Using the roll back trans command in SQL ensures that the transaction will not be committed unless steps within the transaction have completed successfully. ; In SQL, you can declare local variables and create program logic to get to a solution within a stored procedure. Designing the Interface ; Know what target platforms or devices you must support, be sure to test each screen developed in emulators for each. Understand the impact of tradeoffs made for device compatibility. In the application developed for this chapter, multiple WML cards per page were traded for Pocket IE compatibility.Also the ObjectList control was avoided for this same reason. ; Limit the size of the UI; that is, keep it small and concise. ; For more control over individual device rendering of content, look into device filters and using the Mobile Capabilities component (a component similar to the ASP.NET HttpBrowserCapabilities component and the earlier MSWC.Browser component used in standard ASP). www.syngress.com 175_NETmobile_08.qxd 12/28/01 1:45 PM Page 390 Creating a Mobile Movie Ticket Purchasing Application • Chapter 8 391 ; For scalability and code reuse, create stored procedures and data access components to handle the interaction between the page and the database. ; Use the TextView control instead of the Label control when you need to pass markup with text. ; Remember, not all mobile devices can handle cookies; if you think you may have to use any session variables or are not sure if some of your code is relying on cookies, switch the Web.config file’s sessionState attribute cookieless to true. Q: Does the mobile framework have form validation controls similar to ASP.NET Web forms? A: Yes. However, this is beta software and these controls still need some work. Q: Do I need to learn WML to develop with Mobile .NET? A: No, almost all of the code is hidden behind an object model.The advantage of this is that as new devices hit the market, you can add new style templates with minimal recoding of applications. Q: Can I see the WML that is generated by the mobile Web forms? A: Yes, if you are testing with the Nokia 3.0 Toolkit. It will show you the WML that the phone emulator is rendering. However, this is not currently a feature in VS.NET Beta 2. www.syngress.com Frequently Asked Questions The following Frequently Asked Questions, answered by the authors of this book, are designed to both measure your understanding of the concepts presented in this chapter and to assist you with real-life implementation of these concepts.
