Write a program that contains a list box (with Sorted = False), a label, and two buttons captioned Add an Item and Delete an Item. When the Add an Item button is clicked, the program should request an item with an input dialog box and then insert the item above the currently highlighted item. When the Delete an Item button is clicked, the program should remove the highlighted item from the list. At all times, the label should display the number of items in the list.  See the figure below.
