5. Click the Start Debugging button on the Standard toolbar.

The ADO Faculty Form program runs in the IDE. The text box object is loaded with the

first Last Name record in the database (Abercrombie), and a navigation toolbar with

several buttons and controls appears at the top of the form, as shown in the following

screen shot:

The navigation toolbar is a helpful feature in the Visual Studio 2010 database programming

tools. From left to right, it contains Move First and Move Previous buttons; a current

position indicator; and Move Next, Move Last, Add New, Delete, and Save Data buttons.

You can change or delete these toolbar buttons by setting the Items property for the

binding navigator object in the Properties window, which displays a visual tool called the

Items Collection Editor. You can also enable or disable individual toolbar buttons.

6. Click the Move Next button to scroll to the second faculty name in the dataset.

The Pais record appears.

   list of names, notice that the position indicator keeps track of where you are in the list
   of records.


8. Click the Move First and Move Last buttons to move to the first and last records of the
   dataset, respectively.


9. Delete the last record from the dataset (Skinner) by clicking the Delete button when
