8). Write a complete VB Sub Procedure called "BtnCost" to do the following task. A copy center charges 6 cents per copy for the first 50 copies, charges 5 cents per copy for copies between 51 and 125, and charges 4 cents per copy for copies between 126 and 200, otherwise, charges 3 cents per copy of order more than 200 copies. Write a VB code that requests the number of copies ordered in an InputBox function and display nside a ListBox LstShow the number of copies the price per copy and total st of printing n a currency format. Use Select Case statement for this program 8 Points 9)F the following table by writing the value of A after each execution The statements are sequential 6Ports 10) Write VB statement or explain briefly for the following short tasks 10.1) Write single VB statement to clear the contents of TxtName control. 10.2) Declare a variable to store value 1234.5678 and then display it 2 decimal places inside ListBox control Point 2 Points 2 Points 2 Points 2 Points LstShow 10.3) How does Visual Basic automatically assign the tab order to controls placed on the form? 10.4) Why are Label controls not capable of receiving focus? 10.5) Declare a variable OneDozen that will always contain 12 items and will never change 11). Convert the following "Select Case" statement into multiple "If. Else End If statements. 5 Points (Variable intA has already been declared and value has been input) Select Case intA Case 1,2 Case 3 to 10 Case 100 Case is 101 Case Else MessageBox Show" 1 or 2) MessageBox.Show 3 to 10) MessageBox Show' Century) MessageBox. Show Too Old) MessageBox. Show Bye Bye") End Select 12). List and explain briefly along with VB examples-three different controls that are used to display output from a 6 Points VB program. 13). Write a complete Visual Basic Program and hand draw GUI to complete the task given below. You must declare appropriate variables, and place appropriate VB controls on a form along with their names to write this VB program. A builder constructs a walkway four feet wide around all four sides of a house as shown in diagram below. The length and width of the house are same. The VB program will input length and width of the house in feet, calculate the area of the house itself, and finally calculate the area of the walkway and cost to pave it. 4 feet Walkway 4 Ft walkway House 4 Ft walk way 4 Fect way 13.1) After reading the rest of the program instructions, design the GUI (hand draw a form with all the controls placed on the form along with their control names) 13.2) When program executes, it Inputs Length (in Feet) and Width (in Feet) of house in two Text Boxes placed on the form 6 Points 4 Points During VB program execution, when button "BtriWalkArea" is clicked, in its VB code window it should do the following (Must declare appropriate variables and use their names in VB codey: ) Calculate the area (LW) of the house using Length and Width 2) Inside a ListBox "LstShow, display Length, Width and Area of house along with appropriate text messages 3) Calculate the area of the walkway knowing the length and width of the house and the width of walkway 4) 3 Points Using decision control, calculate the cost to pave wakway-if the area of the wakway the cost to pave is $12.99 per square feet, otherwise, the cost to pave is $8.99 per square feet 3 Points less than 200 square feet, then 4 Points 5) Inside a ListBox "LstShow, display the calculated walkway area (step 4) and the cost (step 5) to pave in currency format
