Programming with Microsoft VB 2017 Diane Zak Chapter 10 Fence Solution
In this exercise, you create an application that can be used to calculate the cost of installing a fence around a rectangular area. Create a Windows Forms application. Use the following names for the project and solution, respectively: Fence Project and Fence Solution. Save the application in the VB2017\Chap10 folder:
a. Use Windows to copy the Rectangular.vb file from the VB2017\Chap10 folder to the Fence Project folder. Then, use the Project menu to add the file to the project.
b. Modify the Rectangular class to use the Double (rather than Integer) variables.
c. Add a method named GetPerimeter to the Rectangle class. The method should calculate and return the perimeter of a rectangle. To calculate the perimeter, the method will need to add together the length and width measurements and then multiply the sum by 2.
d. Create the interface shown in Figure 10-41 and then code the application. Save the solution and then start and test the application.
