Topic: vla-addobject - Automation Error. Description was not provided

[BazzaCAD]

I posted this issue a few months ago.
https://www.theswamp.org/index.php?topic=51292.0
I added the reg keys and everything worked fine, until now...

I'm now having a new issue, but it's happening with the very same sets of code.

Code - Auto/Visual Lisp: [Select]

1.  
2. (setq LFILTOBJ (vla-addobject
3.   (vla-GetExtensionDictionary
4.     (vla-Get-Layers
5.       (vla-Get-ActiveDocument
6.         (vlax-Get-Acad-Object)
7.       )
8.     )
9.   )
10.   "ACAD_LAYERFILTERS"
11.   "AcDbDictionary"
12. ))
13.  

I get: error: Automation Error. Description was not provided.

Code - Auto/Visual Lisp: [Select]

1. (setq *doc* (vla-get-activedocument (vlax-get-acad-object)))
2. (setq mldrdict (vla-item (vla-get-dictionaries *doc*)"ACAD_MLEADERSTYLE"))
3. (setq newmldrstyle (vlax-invoke mldrdict 'addobject (cadr x1) "AcDbMLeaderStyle"))
4.  

And here I get: error: Exception occurred

I've rechecked the registry & all the ActiveXCLSID keys are there.
I've re-installed Acad & still no change.
This issue is effecting my computer & 2 others in the office, but the 30 other computers seem fine with this same code.
I haven't installed any beta software on my computer. And I especially didn't install anything on the other 2 production computers.
Any ideas, suggestions?

Thanks for the help.

Hi Barry,

Have you been leaving daily gratuities to the programming fairies ??

I've found that helps, and the Taxation Department  recognise the necessity for a regular small payment, so the cash/goods ** are reimbursable.

** note : black jelly beans are usually a particularly good form of payment.

Sorry, I can't be of further help with your issue.

Stay well.

I was hoping I'd be able to get a better answer than these...?
Anyone else have any ideas?

Perhaps run a report on environment variables that differ between the non-functioning systems and not.

One technique I have used to debug those automation errors is putting a crude print-line between every call in my code, that way I know at least which vlax call has caused the automation error - but make sure to remove all nesting - set a temp variable for every (vla-) return value and then it will should cause an automation error on the specific operation that is at fault.

Thanks for the reply.
Sorry I didn't see it sooner.
Are you refining to the AutoCAD system variable? I've done that & there's nothing jumping out that's breaking the code.
Or are you referring to Windows Environment variables?

I have added debug print out to my code. I know the exact line & function that's failing.

It's (vla-addobject) here:

Code - Auto/Visual Lisp: [Select]

1. (setq newmldrstyle (vl-catch-all-apply 'vla-addobject (list mldrdict (cadr x1) "AcDbMLeaderStyle")))

I trap the error & I get "Automation Error. Description was not provided." on the newmldrstyle object.
