Reactor question

Anonymous — Tue, 01 Feb 2000 23:25:07 GMT

Attached is a small jpg of an alert I get when I close a drawing. Would I
get this if a reactor is firing or is there something wrong?

Dan,

I have received this same message as the result of a mistake in AutoLISP
programming in which I tried to close the drawing without answering a
previous prompt.

As I recall, it was difficult to get out of the situation as Esc would not
cancel it. Can't remember what I did, though.

Hope this will give you some ideas what to check.

I am trying to attach reactors to a copied blockref object which has
reactors attached. First, why don't the reactors go with the copied object
in the first place and second, why can't you convert the ename of the newly
created object to a vla-object? I get the following error values when the
subr below is called:

[0.61] (VL-BT)
[1.57] (*ERROR* "Automation Error. Description was not provided.")
[2.52] (_call-err-hook # "Automation Error.
Description
was not provided.")
[3.46] (sys-error "Automation Error. Description was not provided.")

[8.13] (BDR:REACTION-COPIED #

As you can see this is my first reactor attempt. Enlighten me, friends.

You cannot always access objects through ActiveX during some
reactor notifications. In this case, AutoCAD must create
a ActiveX wrapper for the new object before it can be accessed
through ActiveX, and probably can't do that until after the
copy notification is completed.

You should collect the enames in list, store themin a global,
and then in some later notification (like command-ended) act
on the objects.

Would I have to create a command-reator during the callback from the
object-reator to fire another callback on command-ended notification?

You can do it that way or you can just create it in the
same scope as the other reactor, and set a flag in the
latter, and check/clear the flag in the command-ended
reactor. If you chose to create or add the command
reactor in another reactor, then you would have to
remove it after it handles the command-ended notification.

Re: Reactor question

Anonymous — Mon, 21 Aug 2000 20:51:16 GMT

I wrote a simple reactor to change the ltscale in autocad base on whether or
not the user was in model space or paper space. I did this to keep us from
plotting with our linetypes all messed up and at the same time reset the
ltscale so that our drawings appear correctly in model space. It worked
well, except for the annoying extra regen.

This worked fine in A2K, but seems to interfere with the cached layouts in
A2Ki and causes a fatal crash. I believe it has to do with forcing the
regen within the cached layout. If we set autocad to force regens (under
the system tab in preferences) when switching between layouts, we can still
use it in A2Ki, however, it would be nice to be able to cache the layouts to
speed things up. Does anyone know a way to test to see if a layout has been
chached, or perhaps someone has another suggestion.

On a side note, this also appears to interfere with *some* not all excel
items that we have pasted into autocad. The result is that the user cannot
switch between layouts until the reactor has been removed.

Thanks for any suggestions.

I want to call a lisp routine everytime the user toggles between layouts. I
am new to reactors and would appreciate it if someone could get me started
on this.

Thanks

this one works well for us - CJ

;;Place in acaddoc.lsp
(if (not *LayoutSwitch*)
(setq *LayoutSwitch* (VLR-Miscellaneous-Reactor nil '((:VLR-layoutSwitched
. LayoutSwitched))))
)

;;; Layout Switch
;;; by Rob Starz
;;; modified by CJ Follmer

(defun LayoutSwitched (reactor layout / ds)
(if (/= (dictsearch (namedobjdict) "AEC_VARS") nil)
(progn
(setq ds (sa:AecScale))
(if (= ds nil) (setq ds 1.0))
(if (= (nth 0 layout) "Model")
(progn
;(vla-setvariable doc "ltscale" ds)
;(vla-setvariable doc "dimscale" ds)
(setvar "ltscale" ds)
(setvar "dimscale" ds)
)
(progn
;(vla-setvariable doc "ltscale" 1.0)
;(vla-setvariable doc "dimscale" 1.0)
(setvar "ltscale" 1.0)
(setvar "dimscale" 1.0)
)
)
);end progn
);end if
(princ)
)

oops this won't work for you straight out as it calls some routines that you
don't have, but you should get the idea.
