Info

Where to Go from Here So you’ve mastered the basics of programming with Small Basic. Congratulations! If you’re itching for more, there are extra resources online that you can explore. Online Resources Visit http://www.nostarch.com/smallbasic/ to download the extra resources for this book. Once you’ve downloaded and unzipped the file, you’ll see the following materials: Book Programs and Solutions Download the finished programs, all the images you’ll need, some skeleton code for the Programming Challenges, and the solutions to the Programming Challenges and Try It Out exercises. This will save wear and tear on your typing fingers! Additional Resources These are online articles that relate to the topics covered in this book. Many of these were written just to supplement the book!
Review Questions Test your knowledge (or your student’s knowledge). Practice Exercises In addition to the Try It Out exercises and the Programming Challenges in the book, you can find even more exercises to practice. This is also great for teachers who want more options for assignments. The Small Basic Website Visit http://www.smallbasic.com/ to explore the world of Small Basic and programming. You’ll find featured games and programs, documentation, a curriculum for teachers, and much more. Play Games Visit the program gallery to check out what other programmers have made. Join the Community Post on the forums at http://aka.ms/ SmallBasicForum/ to ask questions and share your games and programs with the entire Small Basic community. Learn the Latest News Find out about new releases, extensions, and featured content, games, and apps at http://blogs.msdn.com/b/smallbasic/. Get Teaching Support Teachers can join a private network to get personal support from Microsoft on all Microsoft products at http://aka .ms/MCSTN/. Connect with the Team Email Ed Price and the rest of the Small Basic team at smallbasic@microsoft.com. Tell them the book sent you! Graduating to Visual Basic You can convert any Small Basic program into an equivalent Visual Basic program, which lets you transition to the full power of a professional programming language. First, you’ll need to download Visual Studio for free. Go to http://www.visualstudio.com/ and click Free Visual Studio in the upper right. Next, go to the Small Basic toolbar, click Graduate, select your Output Location, and click Continue. Visual Studio will open with the code translated into Visual Basic! Head back to the Visual Studio website for getting started documentation on Visual Basic and the Visual Studio interface. And if you have any questions about the graduating experience, ask us in the Small Basic forum. 308 Where to Go from Here
