G lobally U nique Id entifier, a unique 128-bit number that is produced by the Windows OS or by some Windows applications to identify a particular component, application, file,database entry, and/or user. For instance, a Web site may generate a GUID and assign it to a user's browser to record and track the session. A GUID is also used in a Windows registry to identify COM DLLs. Knowing where to look in the registry and having the correct GUID yields a lot information about a COM object (i.e., information in the type library, its physical location, etc.). Windows also identifies user accounts by a username (computer/domain and username) and assigns it a GUID. Some database administrators even will use GUIDs as primary key values in databases. GUIDs can be created in a number of ways, but usually they are a combination of a few unique settings based on specific point in time (e.g., an IP Address, network MAC Address, clock date/time, etc.). Create GUID (guidgen.exe) Generates a GUID in a specified format. When you start guidgen.exe, or when you click the New GUID button in the Create GUID dialog box, guidgen.exe generates a GUID. To run guidgen.exe from the IDE On the Tools menu, click Create GUID . The Create GUID tool appears with a GUID in the Result box. Select the format you want for the GUID. Click Copy . The GUID is copied to the Clipboard so that you can paste it into your source code. If you want to generate another GUID, click New GUID .
