1. Design a Windows application named Wallpaper App to calculate the number of single rolls of wallpaper required to cover a room.

2. Create an interface as shown in Figure 1. There are four combo boxes having a drop down style. Display the range of values for the room’s length, width and height from 10 to 35 in the combo boxes while the value in the combo box for the roll coverage should range from 40 to 50 with an increment of 0.5.

3. The calculate button’s click event procedure should calculate and display the number of single rolls of wallpaper required to cover a room. Use a Sub procedure to make the calculation. The number of the single roll should be displayed as an integer.

4. The number of roll should be cleared when changes are made on any of the combo boxes.

5.(For example, if the roll coverage is 45.5 sq. Ft and the length, width and height of the room are 15, 18 and 20 respectively, the number of single

roll will be 30).

Suppose a teacher has five students who have taken four tests. The teacher uses the following grading scales to assign a letter grade to a student, based on the average of his or her four test scores.

Test Score

Letter Grade

90-100

A

80-89

B

70-79

C

60-69

D

0-59

F

Create an application that uses an array of strings to hold the five student names, an array of five strings to hold each student’s letter grades, and five arrays of four single precision numbers to hold each student’s set of test scores.

Equip the application with a set of buttons that allows the application to perform the following:

• Display a form that allows the user to enter or change the student names and their test scores.
• Calculate and display each student’s average test score and a letter grade based on the average.

Input validation: Do not accept test scores less than zero or greater than 100.

1.  Main Form has 15 output Labels
2. Student Form has 25 textboxes

Create these attribute in the table

OperarionID, Operated By , OperatedTo , OperationCos

Code in VB.NET program to allow the user to input two integer values and then the

program print the results of adding, subtracting, multiplying, and dividing among the two

values. See the output below:

• Enter value a:30

• Enter value b:10

• The result of adding is 40.

• The result of subtracting is 20;

• The result of multiplying is 300.

• The result of dividing is 3.

Task 1: Design and develop a program that will compute the take home amount for the loanable amount of the customer. For example, if the customer loanable amount is 100,000.00 and has a 3% per annum interest. The company will deduct the interest for 5 years which is (15,000.00) to the loanable amount, so, the take home amount of the customer is 85,000.00. Your program allows the user to input loanable amount and how many years for the customer to pay the loan. Set the interest per annum to 3%.

Task 2: Write a program implementing Select Case statement that evaluates a character either a 

vowel or a consonant. 

Task 3: Write a program implementing While loop statement, any Do loops statement, any For loops statement that display your Name, School, Course and Year level 10 times with the use of message box.
