How can you check if a string is a valid GUID in vbscript? Has anyone written an IsGuid method?
This is similar to the same question in c#. Here is the regex you will need…
^[A-Fa-f0-9]{32}$|^({|()?[A-Fa-f0-9]{8}-([A-Fa-f0-9]{4}-){3}[A-Fa-f0-9]{12}(}|))?$|^({)?[0xA-Fa-f0-9]{3,10}(, {0,1}[0xA-Fa-f0-9]{3,6}){2}, {0,1}({)([0xA-Fa-f0-9]{3,4}, {0,1}){7}[0xA-Fa-f0-9]{3,4}(}})$
But that is just for starters. You will also have to verify that the various parts such as the date/time are within acceptable ranges. To get an idea of just how complex it is to test for a valid GUID, look at the source code for one of the Guid constructors.
