Complete list of class IDs and names

[mattb-5906]

Is there a complete list of all the built-in class IDs with their corresponing names?

I have looked at the LV2012 Class ID Property help page located here: https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/properties-and-methods/vi-server/generic/c..., but this is incomplete. For example, the RadioButtonsControl has an ID of 72 and is not listed.

Or better yet, are there any VIs out there that can convert a U32 ID value into the corresponding class name?

To my knowledge, that does not exist.  I have filed a corrective action report (CAR #419831) so this will be corrected in the future.  Note that this list can change at almost every version of LabVIEW as new features are added.

Try this.

Thanks for the info DFGray. I noticed some changes in the last few class IDs between LV version on the online documentation. Seems a bit poor - thought they would have added new ones rather than changing them to maintain backwards compatibility.

Thnaks Paul. Unfortunately I've only got LV2009 atm. Would it be possible to save for 2009?

I've taken Paul's VI and expanded it to loop through a few hundred numbers and ignore any errors. I've also downcasted it to 2009 for you. Hopefully this is the complete list you're looking for.

Thanks for converting this bsvare. Works great.

Paul, I'm curious, how did you find this property? On LV2009 it's not listed in the Application class, but the downcasted version still works.
Also can't find it here: http://zone.ni.com/reference/en-XX/help/371361J-01/lvprop/application_m/ 

Is this another hidden LV thing?

Thanks

If you're using LabVIEW version 2010 or higher, you can enable Scripting... Else for LabVIEW version 2009 or 8.6 you can install LabVIEW Scripting and this will also exposes many additional VI Server classes, properties, and methods.

[mattb-5906]

Thanks for your reply moderator1983.

I've got scripting installed and enabled, but it's still not listed in the drop-down list (see image). This appears to be a non-scripting feature as there's no blue-green container around that method.

Appolgies for going a bit off topic, but trying to understand why I haven't got direct access to this method (and possibly other methods/properties).

[moderator1983]

Ok, so last thing you would like to try:

--> Close LabVIEW (if its opened)

--> Navigate to the LabVIEW.exe folder

--> Open LabVIEW.ini

--> Add 'SuperSecretPrivateSpecialStuff=True' (without quotes) in the INI and start LabVIEW

Try again search for the method.
