Return this book if you've bought it. I bought a copy of this book without reading deeply into(my mistake) cause it looked like it would be useful. I am a C# developer and need to generate some Crystal reports for the project. When I got the book and started reading/looking up info, I found something startling. All of the Code Examples in the Book are VB. Now this doesn't sound bad if your a VB person, but it included C# Examples that were actually VB Code. This was amazing, I'd never seen a mess up by an editor like this. I returned this when i saw it and got a different book that actually had C# in it. Worst Book ever....
