28 Appendix H Using ADO.NET 2.0 with Microsoft Access Databases You have completed the concepts section of Appendix H. The next section is the Programming Tutorial section, which gives you step-by-step instructions on how to apply the appendix’s concepts to an application. A Programming Example follows the Programming Tutorial. The Programming Example is a completed program that demonstrates the concepts taught in the appendix. Following the Programming Example are the Quick Review, Key Terms, Self- Check Questions and Answers, Review Questions, Review Exercises – Short Answer, Computer Exercises, and Case Projects sections. PROGRAMMING TUTORIAL Trivia Game Application In this tutorial, you create an application that displays trivia questions and answers. The questions and answers are stored in a table named Game1, which is contained in a Microsoft Access database named Trivia.mdb. The Game1 table contains nine records. Each record contains six fields named Question, AnswerA, AnswerB, AnswerC, AnswerD, and CorrectAnswer. The application also keeps track of the number of incorrect responses made by the user, and it displays that information after all nine questions have been answered. The Trivia Game application’s user interface is shown in Figure H.37, and its TOE chart is shown in Figure H.38. Appendix H C5779 39147 Page 28 07/10/06--JHR FIGURE H.37 MainForm

To open the Trivia Game solution file: 1. Start Visual Studio. If necessary, close the Start Page window. 2. Open the Trivia Game Solution (Trivia Game Solution.sln) file, which is contained in the VbReloaded\ Appendix H\Trivia Game Solution folder. The user interface shown earlier in Figure H.37 appears on the screen. First, you will connect the Trivia database to the application, and then you will preview the data. To connect the Trivia database to the application, then preview the data: 1. Click Data on the menu bar, and then click Show Data Sources to open the Data Sources window. 2. Click Add New Data Source in the Data Sources window to start the Data Source Configuration Wizard. See Figure H.39.
