Incorrect Capitalization In Code Sample The beginning of the Caret class towards the bottom of Page 244 contains five instances of the following program instruction: [DLLImport("user32.dll")] When the reader attempts to compile the Caret.cs file, the following error message is thrown: ...Caret.cs(13): The type or namespace name 'DLLImport' could not be found (are you missing a using directive or an assembly reference?) The reason the compiler generated this error is because the two letter "L's" in the word "DLLImport" are capitalized. (Please note an example of the proper way to write this statement can be found on the sixth line of Page 239.) Error Solution: Change the two upper case letter "L's" to lower case letter "l's." Correction: The beginning of the Caret class towards the bottom of Page 244 should contain five instances of the following program instruction: [DllImport("user32.dll")]
