add subtract numbers selectable


Recommended Posts

How can I make this allow me to select the text to be edited?

 

(defun c:AFF ( / ss)
 (vl-load-com)
 (if (and (setq ss (ssget "X" (list (cons 0 "*text"))))
      (setq amt (getreal "\nPlease type the amount you would like to add: ")))
   (progn
     (mapcar '(lambda (z) (vla-put-textstring z (rtos (+ (atof (vla-get-textstring z)) amt) 2 2)))
         (mapcar 'vlax-ename->vla-object (vl-remove-if 'listp (mapcar 'cadr (ssnamex ss)))))
     )
   )
 (princ)
 )

If you're going to work with the Vla-Object for each entity in the Selection Set, then simply iterate the ActiveSelectionSet Collection Object instead of applying Vlax-Ename->Vla-Object to an iterated Selection Set (using SSNAME)... Much faster :thumbsup:

 

(vl-load-com)

(defun c:FOO ( / ss amt)
 (if (and (setq ss (ssget "_:L" '((0 . "*TEXT"))))
          (setq amt
                 (getreal "\nPlease type the amount you would like to add: ")
          )
     )
   (progn
     (vlax-for x (setq ss (vla-get-activeselectionset
                            (vla-get-activedocument
                              (vlax-get-acad-object)
                            )
                          )
                 )
       (vla-put-textstring
         x
         (rtos (+ (atof (vla-get-textstring x)) amt) 2 2)
       )
     )
     (vla-delete ss)
   )
 )
 (princ)
)
