Query: an ERROR on chapter1

i have to say, that for someone who wants to use C# and directX this book is a one stop shop, i think that the general idea of this book totally hit the right point,yet, there are a lot a lot, of code errors, in the printed text,and when you get an error on the introduction chapter,(the "device" word),you may question, how seriously did these people take them selves,and, when you do not include an Appendix on how to install the SDK's...then with all respect, you cant say this is a book for beginners,if i was a beginner, i would probably leave the book, around chapter1 with the "device" error, and the assmupsetions of a working sdk.the book is very good, but everything around it is very very bad.
