When this page was started, there were almost 800 sample files. These have been broken down into an initial broad set of categories which may alter as I wade through the code and test before publishing.
However, as a placeholder, I will list the current set of categories.
Initially there was a severe amount of banging my head against the wall while fighting with the Google Sites HTML to try and make the code samples readable and easy on the eye. Thanks must go to Red-Gate for their simple (and free) code prettifier. Nothing else came close to producing sensible HTML.
