  • Each Category form will have no less than three items to choose from. For example, a music category could have the CD’s Bon Jovi, GNR and Owl Poison. A Video Games category could have the NES, SNES and Atari systems, etc.
  • When a user selects an item(s), the selected item(s) are added to the ListBox on the startup form and all labels (SubTotal, Tax, etc.) are robustly updated.
  • You can decide how an item is selected, but you have to use a different selection method for each form (like image click, checkbox, radio button, listbox, etc.)
  • About Form
  • Needs an image of you
  • Short blurb about yourself…one line is fine. Can be your major, hobby, favorite basket weaver…whatever
  • Tax rate is .07

This project is about five concepts coming together: using multiple forms, sharing information between forms, using methods to simplify and modulize a program, using a listbox, and using menus instead of buttons. With that in mind, a good place to begin is with the startup form…

Startup Form

  • Start with creating the menu structure in place of buttons
  • All methods are contained in this form
  • This for is the hub of the project
  • Fields in this form are private and accessed through methods

Category Forms

  • Minimum of 3 required
  • Must add items to the StartUpform in different ways (radio buttons, item click, etc)
  • Little code – they all call the same methods to add items and update labels

Fields you can use for this project double dblTax

const double DBL_TAXRATE = .07 double dblTotal int intItemCount

Methods you can use for this project

  • Void method to add an item to the form o 1 parameter – item name
    • Called by any category form to add a single item to the main form listbox o Will get the item price o Will add the item to the listbox o Will update labels
  • Void method to calculate\update the subtotal, tax, total and item count variables o 1 parameter – the item cost o Update the item count o Update the subtotal o Update tax o Update total
  • Void method to update the form labels o No-arg method o Update all the form labels
  • Value returning method to get price of item o 1 parameter – item name
    • Returns item price
  • Void method to remove an item from the listbox o No-arg method o Get the selected item
    • Remove the item
  • Void method to handle shipping o No-arg method
    • Check the status to the shipping checkbox o Figure out the shipping cost based on item count oUpdate shipping and total label
