Introduction

If you have programmed with Windows or used a Windows-based operating system for any length of time you will see that it is really an all-encompassing OS. Unlike with other types of software development, we don't need to interact with device drivers or create three dimensional graphics for our users. Most of what we need to do involves integrating with the file system; that is searching for files or folders and running external applications.

Occasionally, we may need to go a little deeper than that. There may be instances where we need to check the user's environment, query the registry, or check for specific administrator permissions. These can all be performed within NAV, although many require a little outside help from a built-in or custom automation control.
