CODE BUG FIXES and ANNOYANCE CORRECTIONS

Person.Age property. (Various chapters in the book where Person class in used in programs.) The Person.Age property miscalculates the age under certain circumstances. The code has been updated on the C# For Artists Support Site to correct this problem. Thanks to Jon Goosens, a student in my Fall 2010 ITP-136 class for catching this bug. Good catch Jon!

RobotRat.cs (Chapter 3 project walk through.)  There is a bug in the MoveForward() method that will result in an array index out of bounds exception. This is caused by calling the floor.GetLength(n) method with n = 1 when moving SOUTH and the pen is UP when the floor array has a greater number of rows than columns. To replicated the bug, in the Main() method, create the instance of RobotRat by calling its constructor with, let's say, rows = 30 and columns = 20 like this: RobotRat(30, 20). Recompile and run the program. Turn the robot rat to face SOUTH and keep the pen UP. Move 25 spaces then set the pen DOWN. Turn EAST and try to move. An exception will be thrown. The code has been fixed and updated on the C# For Artists support site for all iterations of the RobotRat code containing the faulty MoveForward() method.  Thanks to the coworker of a student in my Fall 2010 ITP-136 class for catching this bug. 

RobotRat.cs (Chapter 3, Complete Listing on page 67) The comments above the PrintMenu() method should read "Prints the menu to the screen"

EmployeeMVC (Chapter 25)  Added missing files IEmployeeFactory and EmployeeFactory to the Common folder. Fixed a bug in the program that manifested itself when saving a file of employee data to any directory other than the working directory. When this occurred, the program's working directory changed and the program could no longer find the Commands.dll file.
