Product overview

This component provides only one method to generate Universally Unique Identifiers (UUID, also known as Globally Unique Identifiers, GUID) that can be used to identify various objects such as sessions, users, database records, transactions, products and etc. UUID is a 128-bit value. Basically, the operating system is responsible for a creation of a new unique UUID each time when it is requested. Each UUID is absolutely unique and can be used as a persistent identifier in a distributed environment. To a very high degree of certainty, this component generates a unique values - no other invocation, on the same or any other system (networked or not), should return the same value.

This component is designed to be used in such script languages as VBScript, JavaScript, ASP, WSH, Transact SQL and etc. There is no special requirement neither for operating system nor for hardware.

Functions

mode (optional) specifies a format of the return value:
If mode is 0 or is missing then the return value does look like "{0FB00916-0430-43AB-824B-35AB2ED1B4FC}".
