  •  Save (on menu-bar): Save the input information and the selected item(s) to file(s). You may design the file format but the information should be readable (e.g. contains the item names). Before saving, check: 

o The ID has four digit starting from 1000, otherwise, display a message box:

o Once the OK button clicked, the text of ID should be cleared

o If the quantity of a item is not entered or not greater than zero, this item will be ignored  (you may put "none" as the item and quantity to be zero in the file)

o You must use native C++ unmanaged code to manipulate the file

o After successfully save the file, display a message box with the input Name:

o Once the OK button clicked, all entered information should be cleared

  • Exit (on menu-bar): Close the form/window
  • "Get ID record" button:  Retrieve the purchasing information of the ID entered, like:(hint:  radioButton1->Checked = true; //this changes the radio-button 1 being selected)
  • Space in the input text for Name field should be allowed
  • Only ONE radio-button can be selected for each row of item. Once a radio-button is selected, the corresponding price shouldbe shown  after  "Each Price (HK$)"  label  and the  price after  "Total Price  ->"  button  should be  hidden  (e.g.  in the above diagram, HK$ 1400 will be disappeared when radio-button "Clock" is clicked). The each price is as follows:

o  Clock: 180.00,  Watch: 200.00,  Timer: 220.00,  Alarm: 250.00

o  Baseball: 200.00,  Volleyball: 250.00,  Football: 300.00,  Basketball: 350.00

o  Mizuno: 150.00,  Puma: 180.00, Addidas: 200.00, Nike: 250.00

  • "Total Price ->" button: Calculate the sum of all item(s) price and display the sum. If the number for the Quantity field is not greater than zero or not entered, just neglect the item.
  • "Clear All" button: Clear all entered information (display the form as Figure 1)
