Chapter 16. Writing an Extension > Creating a Unique GUID

Creating a Unique GUID

Each extension is ultimately identified by a complex number called a globally unique identifier (GUID). Any extension you write will need its own GUID, and it is best to not make one up. The reasons to have GUIDs are found in the history of software development and how components such as software interact with each other and the operating system.

As computers have become more complex, the use of names to describe unique content, features, and functionalities has become problematic. Names created by independent parties who were developing these features often were identical to names from other developers. Usually, this similarity was unintended, but the results were that Windows (and applications) often got confused as to which object was being referred to because two items had the same name.
