Question

Create an application that calculates and displays the amount of a homeowner’s property tax. The tax is 1.35% of the property’s assessed value, which will be entered by the user. a. Prepare a Planning Chart for the application. b. Draw a sketch of an appropriate interface. Be sure to follow the GUI design guidelines covered in the chapter. The guidelines are summarized in Figure 2-20. (If you want to include an image in the interface, you can either use your own image file or download an image file from openclipart.org. When downloading from openclipart.org, be sure to use the SMALL IMAGE (.PNG) button.) c. Create a Windows Forms application. Use the following names for the project and solution, respectively: Tax Project and Tax Solution. Save the application in the VB2017\Chap02 folder. Change the appropriate properties of the form. Also, be sure to verify the name of the startup form. d. Use your Planning Chart as a guide when building the interface. e. Code the Exit button. (You do not need to code the button that calculates and displays the tax.) Save the solution and then start the application. Test the access keys, tab order, and Exit button and then close the solution.

Answer 1

Here is the solution. Please do upvote thank you.

a) Planning chart:

Create the form, and add two buttons, calculate and exit, and add two labels and two textboxes, as shown in the second image. Now code the buttons as shown in the image file, and debug. The required program is ready.

b) The design is as shown in the second image,please do find the images at last.

c) And the code for the windows form is also ready. Steps in brief. Open visual studio, Go to file menu and hit on New. Now choose Windows form from project type, and give the project name VB2017/chap02. Now code as explained in A, and as explained in images.

D) We just need to follow the plan to build the interface.

E) The code of exit button. Double click exit button to enter code-behind, and add this.Close(); And that's it, we have the project ready.

Explanation:

And If you want Rounded off value, then you need to all below code in calc_click method. Double click on calc, and code behind will appear. Add the below code over there:

double tax = Convert.ToDouble((textBox1.Text)) * 5/100;

double Roundedtax = Math.Round(tax, 2);

textBox2.Text = Convert.ToString(Roundedtax);

textBox2.Show();

textBox3.Text = Convert.ToString(Convert.ToDouble(textBox1.Text) + Convert.ToDouble(textBox2.Text));

textBox3.Show();

For dollar sign, add a label after each textbox, and change its text to $s.

i hope it helps..
