AutoLisp - Each Document

How does someone get the variable for each open instance of documents in a cad program?

;; Gets the application
(setq objApp (vlax-get-acad-object))
;; Object collection of open documents
(setq objDocs (vla-get-documents objApp))

;; Each open document
(setq iCount (vla-get-count objDocs))
(setq iItr1 0)
(repeat iCount ; Also tried foreach
    ;; This is where I'm stuck 
    ;; ssname works with selection sets, not objects. 
    (setq objOpenDoc (ssName objDocs iItr1));---; <-Error
    (princ "\nDoc : ")(princ objOpenDoc)(terpri); Printing Results
    (setq iItr1 (1+ iItr1));--------------------; Next Document
);repeat
Solution

  • Instead of repeat, use vlax-for. Vlax-for allows for collections within object variables to be individually passed into the symbol variable.

    ;; Gets the application
(setq objApp (vlax-get-acad-object))
;; Object collection of open documents
(setq objDocs (vla-get-documents objApp))

;; Each open document
(vlax-for objOpenDoc objDocs
    (princ "\nDoc : ")(princ objOpenDoc)(terpri); Printing Results
);repeat

    Result:

    Command: (progn (setq objApp (vlax-get-acad-object))(setq objDocs (vla-get-documents objApp))(vlax-for objOpenDoc objDocs (princ "\nDoc : ")(princ objOpenDoc)(terpri)))
