48 Appendix H Using ADO.NET 2.0 with Microsoft Access Databases b. Open the Morgan Industries Solution (Morgan Industries Solution.sln) file contained in the VbReloaded\Appendix H\Morgan Industries Solution-Ex3 folder. c. Add the FillByFulltime query to the TblEmployTableAdapter object. (You can use Figures H.28 through H.31 as a guide.) d. Associate the FillByFulltime query with a ToolStrip control. (You can use Figures H.33 through H.35 as a guide.) e. Save the solution, then start the application. Test the FillByFulltime button on the ToolStrip control. The interface should appear as shown in Figure H.36. f. Click the Exit button to end the application. g. Create another query. The query should select only the records for parttime employees. Arrange the records in order by the Rate field. Use FillByParttime as the name for the query’s Fill method, and use GetDataByParttime as the name for its GetData method. h. Associate the FillByParttime query with a ToolStrip control. Also associate the Fill query with a ToolStrip control. i. Save the solution, then start the application. Test the FillByFulltime, FillByParttime, and Fill buttons on the ToolStrip controls. j. Click the Exit button to end the application, then close the solution. 4. In this exercise, you modify the application from the chapter’s Programming Example. a. Create the Cartwright Industries application shown in the chapter’s Programming Example. Save the application in the VbReloaded\ Appendix H folder. b. Create a query that allows you to display the data in ascending order by the item number. Also create a query that allows you to display the data in descending order by the price. c. Associate the two queries with two ToolStrip controls. d. Save the solution, then start and test the application. e. Click the Exit button to end the application, then close the solution. 5. In this exercise, you modify the application you created in the chapter’s Programming Tutorial. a. Use Windows to make a copy of the Trivia Game Solution folder, which is contained in the VbReloaded\Appendix H folder. Rename the copy Modified Trivia Game Solution. b. Open the Trivia Game Solution (Trivia Game Solution.sln) file contained in the VbReloaded\Appendix H\Modified Trivia Game Solution folder. c. Display the question number (from 1 through 9) along with the word “Question” in the interface. d. Add another button to the interface. The button should allow the user to start a new game. Allow the user to click the New Game button only after he or she has answered all nine questions. e. Save the solution, and then start and test the application. f. End the application, then close the solution. 6. In this exercise, you modify the application you created in the chapter’s Programming Tutorial. a. Use Windows to make a copy of the Trivia Game Solution folder, which is contained in the VbReloaded\Appendix H folder. Rename the copy Disc Trivia Game Solution. b. Open the Trivia Game Solution (Trivia Game Solution.sln) file contained in the VbReloaded\Appendix H\Disc Trivia Game Solution folder. Appendix H C5779 39147 Page 48 07/10/06--JHR
Case Projects 49 c. Allow the user to answer the questions in any order, and also to change his or her answers. (You will probably need to modify the interface by including additional buttons.) Only display the number of incorrect answers when the user requests that information. d. Save the solution, and then start and test the application. e. End the application, and then close the solution. Appendix H C5779 39147 Page 49 07/10/06--JHR 7. In this exercise, you find and correct an error in an application. The process of finding and correcting errors is called debugging. a. Open the Debug Solution (Debug Solution.sln) file, which is contained in the VbReloaded\Appendix H\Debug Solution folder. b. Open the Code Editor window. Review the existing code. c. Notice that a jagged line appears below one of the lines of code in the Code Editor window. Correct the code to remove the jagged line. d. Save the solution, and then start and test the application. Notice that the application is not working correctly. Click the Exit button to end the application. e. Correct the errors in the application’s code, and then save the solution and start the application. Test the application. f. Click the Exit button to end the application, and then close the solution. Case Projects Addison Playhouse In this Case Project, you use a Microsoft Access database named Play. The Play.mdb database file is located in the VbReloaded\Appendix H\Access Databases folder. The Play database contains one table named tblReservations. The table contains 20 records, each having three fields: a numeric field named Seat and two text fields named Patron and Phone. Create an application that allows the user to display the contents of the dataset, and also to add, delete, and save records. In the Properties window, set the Play.mdb file’s Copy to Output Directory property to Copy if newer. College Courses In this Case Project, you use a Microsoft Access database named Courses. The Courses.mdb database file is located in the VbReloaded\Appendix H\Access Databases folder. The Courses database contains one table named tblCourses. The table contains 10 records, each having four fields: course ID, course title, credit hours, and grade. The credit hours field is numeric; the other fields contain text. Create an application that uses six queries. Five of the queries should allow you to display the data for a specific grade (A, B, C, D, F). The sixth query should display all of the records in their original order. Sports Action In this Case Project, you use a Microsoft Access database named Sports. The Sports.mdb database file is located in the VbReloaded\Appendix H\Access Databases folder. The Sports database contains one table named tblScores. The table contains five records, each having four fields that store the following information: name of the opposing team, the date of the game, your favorite team’s score, and the opposing team’s score. Create an application that allows you to view each record, and also to add, delete, and save records. In the Properties window, set the Sports.mdb file’s Copy to Output Directory property to Copy if newer.
