Computer Exercises
1. In this exercise, you create an application that accesses the data stored in a
database. The application displays the data in a DataGridView control.
a. Open the Morgan Industries Solution (Morgan Industries Solution.sln)
file, which is contained in the VbReloaded\Appendix H\Morgan
Industries Solution-Ex1 folder.
b. Complete the interface, using Figure H.13 as a guide. In the Properties
window, set the Employees.mdb file’s Copy to Output Directory property
to Copy if newer. Doing this allows you to save the changes made to the
dataset.
c. Save the solution, then start the application. The interface should appear
as shown in Figure H.16. Verify that the BindingNavigator control works
appropriately. (Do not try to save an empty record.)
d. Click the Exit button to end the application, then close the solution.
2. In this exercise, you create an application that accesses the data stored in a
database. The application displays the data in label controls.
a. Open the Morgan Industries Solution (Morgan Industries Solution.sln)
file, which is contained in the VbReloaded\Appendix H\Morgan
Industries Solution-Ex2 folder.
b. Complete the interface, using Figure H.18 as a guide. Also be sure to code
the Next and Previous buttons. (The code is shown in Figure H.23.)
c. Save the solution, then start the application. The interface should appear
as shown in Figure H.20. Test the Next and Previous buttons to verify
that they are working correctly.
d. Click the Exit button to end the application, then close the solution.
3. In this exercise, you modify the application from Computer Exercise 1. The
modified application will allow the user to display the full-time records,
part-time records, and all of the records.
a. Use Windows to make a copy of the Morgan Industries Solution-Ex1
folder, which is contained in the VbReloaded\Appendix H folder.
Rename the copy Morgan Industries Solution-Ex3.
