Perhaps dig around in the SecurityParams Object?

well...ther is what I come with..

Code: [Select]

(setq AcSecPar (vla-getinterfaceobject
                         (vlax-get-acad-object)
              "AutoCAD.SecurityParams.18"
            )
  )
(vlax-dump-object AcSecPar t)

But I have no result..

Code: [Select]

; IAcadSecurityParams: Security Parameters Interface
; Property values:
;   Action = 0
;   Algorithm = 0
;   Comment = ""
;   Issuer = ""
;   KeyLength = 0
;   Password = ""
;   ProviderName = ""
;   ProviderType = 0
;   SerialNumber = ""
;   Subject = ""
;   TimeServer = ""
; No methods

also,..AutoCAD can detect this kind of drawing and change the icon. (see below)
so if autoCAD can....we can !   :pissed:

the only way I've seen (for the moment)...is with the (open "....  and get information in there..
