I would not recommend this book to anyone. I have been fighting with the fragment project for months now, and nobody can figure it out, it wont run, a debugger opens with almost 100 lines of issues, I have followed the book exactly. where is the writer of this book, you would think he would be on this site trying to help out, but no he is not, this book is going in the garbage, and I will buy one that will actually teach me how to code, instead of copy 100 lines out of a book, and then watch it do nothing.
