Hello...
Title:  Convert ads_name to VLA-Object from C++ARX?

I  want a function convert "vlax_ename2vla_objectC"
The "vlax_ename2vla_objectC",will convert "ads_name" to "vla-object"
You replace the "????" with your source C++ARX.
I need only VisualC++ARX
I need one function ads_retVLA_object(rr);

The function "vlax_ename2vla_objectC" return value idem with llisp:

(type (vlax-ename->vla-object (car (entsel)))
Please help me...!

[source=vlisp]
(Defun vlax_ename2vla_objectL(arg1_as_RTENAME / rr)
  (setq g (type arg1_as_RTENAME))
  (setq rr (vlax-ename->vla_objectarg1_as_RTENAME )
rr)
[/source=vlisp]



[source=cpp]

int
/*FCN*/vlax_ename2vla_objectC()
{
    struct resbuf *pArgs =acedGetArgs ();
    if(!pArgs)
      return acedRetNil();
     if(pArgs->restype != RTENAME)
      return acedRetNil();

    AcDbObjectId id;
    if(acdbGetObjectId(id,pArgs->resval.rlname) != Acad::eOk)
      return acedRetNil();
   "????"
   "????"
   "????"
   ads_retVLA_object(VLA-OBJECT)
}

Hello,

Have you tried using the "ObjectIdToObject" method in the IAcadDocument interface ?

This will provide you with a pointer to the COM Interface (Ex : IAcadCircle) for the ObjectId that you pass to it as parameter.

You can find it under <ObjectARX folder>\samples\com\AsdkMfcComSamp_dg\CAcadDocument.h.

Hope this helps.

Hi, Balaji!
But how can return this pointer from arx to lisp? IMHO it is impossible.

Hi Alexander,

I am not sure if the developer wants to pass it over to Lisp, because in that case the "vlax-ename->vla-object" would get the vla-object.

I thought the developer wanted to get the COM object using an ObjectId using C++ alone and had provided the Lisp code as a demonstration of what he wanted to do.

Sorry, but I might be wrong in understanding the question.

Hi, Balaji!

diagodose2009 try to develop lisp to arx compiler/converter. It is understandable on the questions which he regularly gives on this forum. That is why hi try to emulate (vlax-ename->vla-object) lisp-function with ObjectARX code.
