What I would suggest you do is start with code that *does* work and then modify it gradually so that it does what you want. When it breaks, that's when you broke it. :)
My book's Drawing chapter can be studied here:

And even better, the example projects themselves can now be downloaded here:

The point is that this way you can start with an *entire project* that works. When you copy and paste code into your own project, all kinds of conditions can be incorrect, but when you have an entire project that embodies the example code and that the author is telling you works right out of the box (just build and run and look at the result) you have a firm starting-place from which to experiment. m.
