open read only script

I am trying to figure out hoe to open a series of drawings read only using a script file, but cannot figure out what forces Autocad to open read only. I'm trying to extract border attributes and would like to do so while others have the drawing open. I then can close the file with no save....figured that one out after some interesting work with script responses to the close command. just follow clos with "yes" instead of the logical "no" response.

 

I am trying to figure out hoe to open a series of drawings read only using

only.

Make sure the file is already open before AutoCAD opens it:
(open "X:\\MyPath\\MyDrawing.dwg" "a")
OPEN X:\MyPath\MyDrawing.dwg _Yes

 

;;; opens and activates a file as Read-Only
(defun openRO (fna)
(vla-activate (vla-open (vla-get-documents (vlax-get-acad-object)) fna
:VLAX-TRUE))
)
