Preston Enterprises stores employee IDs and salaries in a sequential access file named Employees.txt. Open the VB2015\Chap10\Preston Solution\Preston Solution (Preston Solution.sln) file. Open the Employees.txt file, which is contained in the project’s bin\ Debug folder. Each line contains an employee’s ID followed by a comma and a salary amount. Close the Employees.txt window.

a. Define a structure named Employee. The structure should contain two member variables: a String variable to store the ID and a Double variable to store the salary.

b. Declare a class-level array that contains five Employee structure variables.

c. The frmMain_Load procedure should read the IDs and salaries from the Employees. txt file and store them in the class-level array. It should also add the IDs to the list box.

d. When the user selects an employee ID in the list box, the employee’s salary should appear in the lblSalary control.

e. Test the application appropriately.
