This exercise assumes you have completed the Richardson County application from Exercise 1 in each of Chapter 2’s lessons. Use Windows to copy the Richardson Solution folder from the VB2015\Chap02 folder to the VB2015\Chap03 folder, and then open the Richardson Solution (Richardson Solution.sln) file. Open the Code Editor window and enter the three Option statements in the General Declarations section. Modify the application’s code to use variables and the TryParse and ToString methods rather than the Val and Format functions. Save the solution, and then start and test the application.
