I want to generate GUID strings in VBScript. I know that there\'s no built-in function in VBScript for generating one. I don\'t want to use random-generated GUIDs. Maybe the

Answer 1

How Can I Create a GUID Using a Script? (in: Hey, Scripting Guy! Blog) says this:

Set TypeLib = CreateObject("Scriptlet.TypeLib")
Wscript.Echo TypeLib.Guid

However, note that Scriptlet.TypeLib.Guid returns a null-terminated string, which can cause some things to ignore everything after the GUID. To fix that, you might need to use:

Set TypeLib = CreateObject("Scriptlet.TypeLib")
myGuid = TypeLib.Guid
myGuid = Left(myGuid, Len(myGuid)-2)
Wscript.Echo myGuid

Answer 2

Set tlib = Server.CreateObject("Scriptlet.TypeLib")
strGuid = tlib.Guid

Answer 3

' Returns a unique Guid on every call. Removes any cruft.
Function CreateGuid()
    CreateGuid = Left(CreateObject("Scriptlet.TypeLib").Guid,38)
End Function

Answer 4

Function CreateGUID
  Dim TypeLib
  Set TypeLib = CreateObject("Scriptlet.TypeLib")
  CreateGUID = Mid(TypeLib.Guid, 2, 36)
End Function

This function will return a plain GUID, e.g., 47BC69BD-06A5-4617-B730-B644DBCD40A9.

If you want a GUID in a registry format, e.g., {47BC69BD-06A5-4617-B730-B644DBCD40A9}, change the function's last line to

CreateGUID = Left(TypeLib.Guid, 38)
