reactor query

Here are the two main reactors I've set up as part of our in-house system:

;;; Reactors
;;;
;;; resets ltscale to dimscale value
(defun varChanged (calling-reactor varChangeinfo / var_name)
(setq var_name (nth 0 varChangeinfo))
(if (and (= var_name "DIMSCALE")(/= (getvar "cvport") 1))
(setvar "ltscale" (* ARCTSCAL (getvar "dimscale")))
)
)
(vlr-sysvar-reactor nil '(vlr-sysVarChanged . varChanged)))
;;; resets ltscale etc if layout space is changed
(defun ChangedLayout (reactor layout / )
(if (= (nth 0 layout) "Model")
(progn
(setvar "ltscale" (* (if (= (getvar "dimscale") 0) 1 (getvar "dimscale"))
ARCTSCAL))
(arctsetvar "cvport" 2)
)
(progn
(setvar "ltscale" ARCTSCAL)
(setvar "psltscale" 1)
(arctsetvar "cvport" (getvar "cvport"))
)
)
)

(if(not *LayoutLTS*) (setq *LayoutLTS* (VLR-Miscellaneous-Reactor nil
'(VLR-layoutSwitched . ChangedLayout)))))
(princ)

I've put these in the .mnl file - and they work although there is a strange
error happening:

opening a new .dwg or a .dwg that predates the reactor yields:

; error: no function definition: VARCHANGED
; error: no function definition: VARCHANGED
; error: no function definition: VARCHANGED
; error: no function definition: VARCHANGED
; error: no function definition: VARCHANGED
; error: no function definition: VARCHANGED

AutoCAD menu utilities loaded.

and the reactor works just fine. dwgs that have been opened and saved do
not open with this error.

certainly has me puzzled.

Please notice the files loaded sequence of autocad. I meet the same
question when using reactors. You must confirm the function which is
connected with reactor loaded before reactor actived.

- what AutoCAD version
- use vlr-set-notification and 'active-document-only for your reactors.

test with that, and let us know

 

Hey Luis!

The error message doesn't appear in 2004, only 2000, and as we are finally
moving to 2004, well I'll just chalk it up to acad 2000 reactior
problems....

 

I was getting similar errors on a command reactor in 2000 until I made a
:vlr-beginclose dwg-reactor to vlr-remove the reactor. I'm going to look
into the vlr-set-notification that Luis mentioned.

 

good...

there are issues if you apply setvar in pre-version of AutoCAD 2004.... and the idea is to implement everything in active-x code (vlisp).

Luis.
