Delphi UUID generator

Question

Does Delphi have anything built-in to generate UUIDs?

Answer 1

If you're using one of the latest version of Delphi, and include SysUtils, you can call TGuid.NewGuid to generate a new guid.

NewGuid is actually implemented in a helper class for TGuid (TGuidHelper), which is declared in SysUtils.

This function calls the CreateGUID method (also in SysUtils and already mentioned in the answer by Mitch Wheat), which is actually a cross platform function that calls different libraries depending on the platform it runs on.
