Create GUIDs

[Martin Walke]

Hi all,

Can someone tell me how I can create a GUID? I'm still on my previous task of creating composite diagrams and understand now that I need to create an entry in the t_xref table - one of the fields of which, is the GUID of that entry.

I've seen a couple of posts from people with similar problems - the closest is from Paolo saying "from your local GUID dealer ", but he doesn't say where he lives  

Any ideas?

TIA
Martin

Depending on the language you are using there is definitely some GUID library available.
Google is your friend^tm

Hi Geert,

Are you saying that any GUID can be used? What about those that already exist in the model? How do I prevent a clash?

No, he's not.  He's saying that any GUID generated by an appropriate GUID generator can be used.

It should be in the nature of GUIDs that the chances of generating one that clashes with an existing one is vanishingly small.

GUIDs are also known as UUIDs.  As Geert suggests look them up in your favourite search engine.

HTH,
Paolo

Thanks guys [smiley=thumbsup.gif]

It was just the understanding of what EA was doing with the GUIDs that I wasn't sure about. I can now move a little further on with my design!

In Visual Studio 2008 use Tools > Create GUID (other versions of VS will have the same or similar)

Sorry - should have been ultra clear - VB6. But found a couple of routines by googling.

Thanks
