odbx help

hello,
After having read much here, I write my first lisps with odbx, this kind of
little routine :

(defun cdbx_freeze_layers ( / File1 odbx )
(setq File1 (getfiled "Selection du fichier" "C:/traitement/" "dwg" 0 ))
(setq odbx (vla-getinterfaceobject (vlax-get-acad-object)
"ObjectDBX.AxDbDocument.16"))
(vla-open odbx File1 )
(princ "\nCalques gelés :")
(vlax-for layer (vla-get-Layers odbx )
(vla-put-Freeze layer :vlax-true)
(princ (strcat "\n" (vla-get-name layer)))
)
(vla-saveas odbx File1 )
(vlax-release-object odbx)
)

but i can't find any answer about how to modify a variable (I sought with
google, google group ect, here...).

with vl I use someting like :

(vl-load-com)
(setq thisdrawing (vla-get-activedocument (vlax-get-acad-object)))
(vla-GetVariable thisdrawing "fillmode")
(vla-SetVariable thisdrawing "fillmode" 0 )

or

(vla-get-name (vla-get-activelayer thisdrawing ))

but :
(vla-get-name (vla-get-activelayer odbx )) doesn't work and everything that
needs (vla-get-activedocument... too


second point, I tried to use AuditInfo method, but without any success via
odbx because i need (vla-get-activedocument.
(vla-AuditInfo thisdrawing :vlax-true) works

Any help is welcome.
thx,

My english writing is bad, but i will understand you

That is one of the limitations of ODBX, System variables are not accessible.

 

thanks you Jeff,
good explanation why i found nothing about it
