I am needing help with the coding for this assignment.
your task is to develop an application to calculate the amount due for each order. The specifications for the application are described below.
For an order, the user should enter the following information into text boxes: customer name, address, city, state, and Zip Code. An order may consist of multiple items. For each item, the user will enter the product description, quantity,
weight, and price into text boxes. You will need command buttons for Next Item,
Update Summary, Clear, and Exit.
For the Next Item button, validate the quantity, weight, and price. Each must be
present and numeric. For any bad data, display a message box. Calculate the charge
for the current item and add the charge and weight into the appropriate totals. Do not
calculate shipping and handling on individual items; rather, calculate shipping and
handling on the entire order.
When the Update Summary button is clicked, calculate shipping and handling, the Sales Tax, and the total amount due for the order. The Sales Tax is 8 percent
of the total charge and is charged only for shipments to a California address.
The shipping and handling charges depend on the weight of the products. Calculate
the shipping charge as 25 cents per pound and add that amount to the handling charge
(taken from Table 1).
Display the entire amount of the bill in labels titled Dollar amount due, Sales Tax, Shipping
and handling, and Total amount due.
