  6 // III. Programming Exercises: Write source code for the following:
  7 //      Create an order form that allows bags to be purchased. There
  8 //      are six different types: full decorative, beaded, needlepoint
  9 //      design, fringed, fringed beaded, and plain. Create a ListBox
 10 //      object for the different styles. After the user makes a
 11 //      selection, display a message indicating which selection was
 12 //      made. Add to the application by including a control that
 13 //      allows the user to enter the quantity desired. Include a set
 14 //      of radio buttons that contain shipping options of overnight,
 15 //      three day, and standard. The price for each bag is as follows:
 16 //      full decorative $50, beaded $45, needlepoint $40, fringed $25,
 17 //      fringed beaded $50, and plain $20. The shipping charges are
 18 //      based on the total purchase. The following percentages are
 19 //      used: overnight 10%, three day 7%, and standard 5%. Display
 20 //      in a message box the shipping charge along with the selection,
 21 //      quantity, and total cost.
 22 //      Turn in your source code for this program.
