ACAD Mechl And Visual Lisp - Change balloon arrow size

[NirantarVidyarthee]

I want to change the arrow size in AutoCAD mechanical using Visual Lisp. (No other language is allowed by the company).

I have the code in VBA but I have not been able to generate equivalent Vlisp code.

The code fails at the following line saying "; error: Automation Error. Problem in loading application".

Importing the library does not make any difference (but I think it is not necessary).

(vl-load-com)

(setq symBB (vlax-invoke-method (vlax-get-acad-object) 'getInterfaceObject "SymBBAuto.McadSymbolBBMgr")))

From there, I have to get the BomMgr and so on. But I am unable to take the first step itself.

Can somebody help me?

Doesn't anybody use Visaul Lisp with ACM?

Nodosy has even reaf this post.

Is anything wrong with this? Is it a wrong forum for the post?
