(vl-load-com)

If we load code contained vla or vlax etc,sure before that ,we must load
"(vl-load-com)", I want ask how to load code without "(vl-load-com)",but if
the code contained vla/vlax it must be work too.

 

Off the top of my head....

1. Get a list of all the functions implemented in VLCom.arx,
which are not methods of a vla-object. For example,
vlax-get-acad-object; vla-ename->vla-object, etc.

2. If vl-load-com has not been called, then define all of
those same functions described above, like so (using
vlax-get-acad-object as an example):

(if (not vlax-get-acad-object) ; then vl-load-com was not called yet
(progn

(defun vlax-get-acad-object ()
(vl-load-com)
(vlax-get-acad-object)
)

;; Another example, with a function that takes
;; an argument:

(defun vlax-ename->vla-object (x)
(vl-load-com)
(vlax-ename->vla-object x)
)

); progn
); if (not vlax-get-acad-object)

You don't have to do this for vla-* functions since
I don't believe you can call any of them without
first calling one of the functions described above
(that is, functions defined in vlcom.arx, which are
not methods of a vla-object).

This should work even if someone else calls (vl-load-com),
since all of the functions will be redefined.
