Need a program with 3 defined classes (Item.vb, Inventory.vb, InventoryFile.vb) which allows the user to manipulate a store inventory of rental equipment. At startup, the program loads an inventory from inventory.txt and stores it in a dictionary.
Classes
Item Class should encapsulate a single inventory item with properties for ID#, Quantity, Description, Prices for Daily, Weekly and Monthly rentals.
Inventory Class represents a collection containing all items and providing methods for adding, finding and removing items. Internally it should be held in a dictionary object.
InventoryFile Class is responsible for reading the inventory data from inventory.txt at startup and writing all inventory data back to the file when the program ends.
Requirement Specifications:
• The user can input a new rental item and add it to the store inventory
• The user can select an item’s ID number from the Combo Box and remove the item from the inventory.
• The user can select an item’s ID number from the Combo Box and display the item’s properties.
• When the application starts it reads the inventory list from inventory.txt and populates the combo box with ID numbers
• When the application ends it writes the inventory list back to the same file.
Buttons
Add Current Item button adds the info typed in into the inventory.
Remove Current Item button removes the selected item from the inventory.
Display Item populates the Rates, Quantity and Description Information for the selected ID number.
