In this exercise, you complete the Richardson County application from Exercise 1 in both Lesson A and Lesson B. Open the VB2015\Chap02\Richardson Solution\Richardson Solution (Richardson Solution.sln) file.

a. The Calculate button should display the annual property tax, which is $1.50 for each $100 of a property’s assessed value. Code the button’s Click event procedure using the Val function. Use the Format function to display the tax with a dollar sign, a thousands separator, and two decimal places.

b. Code the Clear Screen button. Send the focus to the Assessed value text box.

c. Add a print form control to the application. The control should send the printout to the Print preview window. Code the Print button, being sure to hide the buttons before printing, and then display them after printing.

d. Add appropriate comments in the General Declarations section and in the coded procedures.

e. Save the solution and then start the application. Test the application using 120500 as the assessed value. The tax should be $1,807.50. If your computer is connected to a printer, print the interface.

f. Clear the screen. Now test the application using invalid data. More specifically, test it without entering any data. Then test it using a letter as the assessed value.
