You can find a lot of information about the use of an application and programming by using the application's built-in help features. Today the built-in help is the primary source of information about most applications. The answer to most of the questions I receive about Excel could have been found by looking in the built-in help.

When you encounter a problem you can start searching in the built-in help to see if you find a suitable solution. If you don't find a solution to your problem you can try to search at different websites. It is also possible to search for solutions in the different newsgroups. Mailinglist archives can also be searched if you still haven't found a solutions to your problem.
