If you are using PHP, use the function below. If you have the Microsoft SDK installed on your system, you can use the utility uuidgen.exe, which is located in the "C:\Program Files\Microsoft SDK\Bin" directory.
#RANDOM UUID GENERATOR WINDOWS#
Set TypeLib = Nothing Create a UUID/GUID via the Windows Command Line WScript.Echo(left(NewGUID, len(NewGUID)-2)) Set TypeLib = CreateObject("Scriptlet.TypeLib")
#RANDOM UUID GENERATOR CODE#
Just save the code to a file called createguid.vbs, and then run cscript createguid.vbs at a command prompt. If you are on Windows, you can use the simple VBScript below to generate a UUID. Normal Hex Encoded Base64 Encoded VBScript Function to Generate a UUID/GUID It will return a different one each time. It is running on Linux.Ĭlick the button to run the GUID/UUID generator. The DATA::UUID Perl module by Alexander Golomshtok. UUID/GUID stand for Globally/Universally Unique Identifier. Use this utility to generate a UUID/GUID on the web. § Home > Index > General Interest Generate GUID Online
