Create an application that allows the user to enter the following employee data: First Name, Middle Name, Last Name, Employee Number, Department, Telephone Number, Telephone Extension, and E- mail Address. The valid selections for depart-ment are Accounting, Administration, Marketing, MIS, and Sales. Once the data is entered, the user should be able to save it to a file. Figure 9- 29 shows an example of the application's form. The form shown in Figure 9-29 has a combo box for selecting the department; a Save Record button, which writes the record to a file; a Clear button, which clears the text boxes; and an Exit button. Write code in the Form_ Load event handler that allows the user to enter the name of the file.

Create an application that reads the records stored in the file created by Program-ming Challenge 1. Write code in the form's Load event handler that allows the user to enter the name of the file, and opens the file. The form shown in Figure 9- 30 has a Next Record button, which reads a record from the file and displays its fields; a Clear button, which clears the labels; and an Exit button. When the user clicks the Next Record button, the application should read the next record from the file and display it. When the end of the file is encountered, a message should be displayed.

Create an application that performs the following operations with the employee file created by the application in Programming Challenge 1: • Uses an Open dialog box to allow the user to select the file • Allows the user to enter a new employee record and then saves the record to the file • Allows the user to enter an employee number and searches for a record contain-ing that employee number. If the record is found, the record is displayed. • Displays all records, one after the other • Prints an employee record Equip your application with either a menu system or a set of buttons to perform these operations.
