A introductory level visual basic program

File is attached with images and more details 1. A furniture manufacturer makes two types of furniture—chairs and sofas. The cost per chair is $350, the cost per sofa is $925, and the sales tax rate is 5%. Write a program to create an invoice form for an order. See Figure below. After the data on the left side of the figure below, are entered, the user can display an invoice in a list box by pressing the Process Order button. The user can click on the Clear Order Form button to clear all text boxes and the list box, and can click on the Quit button to exit the program. The invoice number consists of the capitalized first two letters of the customer’s last name, followed by the last four digits of the zip code. The customer name is input with the last name first, followed by a comma, a space, and the first name. However, the name is displayed in the invoice in the proper order. The generation of the invoice number and the reordering of the first and last names should be carried out by Function procedures. 2. A palindrome is a word or phrase that reads the same forwards and backwards, character for character, disregarding punctuation, case, and spaces. Some examples are “racecar”, “Madam, I’m Adam.”, and “Was it a cat I saw?”. Write a program that allows the user to input a word or phrase and then determines if it is a palindrome. The program should use a Boolean-valued Function procedure named IsPalindrome that returns the value True when the word or phrase is a palindrome and the value False otherwise. (Extracredit will be given if you handle special charaters appearing in the sentences) 3. Depreciation to a Salvage Value of 0. For tax purposes an item may be depreciated over a period of several years, n. With the straight-line method of depreciation, each year the item depreciates by 1/nth of its original value. With the double-declining-balance method of depreciation, each year the item depreciates by 2/nths of its value at the beginning of that year. (In the final year it is depreciated by its value at the beginning of the year.) Write a program that performs the following tasks: (a) Request a description of the item, the year of purchase, the cost of the item, the number of years to be depreciated (estimated life), and the method of depreciation. The method of depreciation should be chosen by clicking on one of two buttons. (b) Display a year-by-year description of the depreciation. See Figure below.
