GUID creator

[Ton Plomp]

Does anyone have a GUID creator in LabVIEW?

I know this is a bit lazy, but hey?

I do't know if this is available on platforms other than Windows; look for:

LabVIEW 8.2\resource\Framework\Providers\Builds\Installer\CDK_Utility_GenerateGUID.vi

Here's a simple .NET version (Windows only of course) I wrote a while back...

Thanks, the Builds VI calls this VI:

\resource\Framework\Providers\API\mxLvGenerateGuid.vi

which I suspect to be available on other platforms as well.

The http://www.vartortech.com/visecurity/cryptg.html' target="_blank">CryptoG Toolkit contains amongst many encryption and hash algorithmes a Random Number Generator and based on that a VI to create GUIDs.

All these functions are fully native G code and tehrefore completely plattform independant. It's cost is nothing that should prevent you using it and I can really recommend it.

I hereby resurrect thee...

Was looking for this today myself. This is what I came up with:

Added benefit is if you supply a variant, the VI will make sure that the returned GUID has not already been defined as an attribute key. It of course generates an entirely random number which doesn't conform to any specification that places significance on certain bits etc...but it suits my needs just fine (creating positively unique keys).

Yeah I know. you can't build it.....but couldn't resist

.NET?

dotNET GUID.vi

Found this a while back, though I think I like the .NET implementation better.

This is an old thread, but if anyone else comes across this:

• If using LabVIEW 2020 or later, the best way to generate a GUID is to use the native Create NI GUID.vi which is found in the String >> Additional String Functions palette.

• If using LabVIEW 8.0 to LabVIEW 2019, the best way is to download the Create NI GUID.vi that is found at: GUID Generation for LabVIEW Versions Older than 2020 . This is the same VI as the one that exists natively since LabVIEW 2020, but "Saved for previous..." to LabVIEW 8.0.
• If using a LabVIEW version older than 8.0 on Windows, it's probably best to use the .NET Framework System.Guid object, as document in the following article: How to Generate a MessageID/GUID/UUID With LabVIEW?  and as seen in the screenshot below.

Good stuff!

LabVIEW also has a private built-in method "CreateGUID", which is available from at least LV2009. It was probably also available in earlier versions.

Create GUID.vi

The Create NI GUID.vi is using App.CreateGUID. On Windows App.CreateGUID private method calls CoCreateGuid function, which could be easily called directly from BD, as shown in that cross-posted link.
