Wow, Andrea, that's an awful lot of praise you threw out there!

Should I have answered you in French?

Ne soyons pas chauvin, nivuahc!  
Glad you enjoyed the other link. Reactors are great... when they behave!!!

ok now i've discover something..

The code work only with AutoCAD 2004 and Higher..
In 2002..this code is not reset back the layer..

WHY ?

FRENCH
Je ne sais pas trop pourquoi ce foutu code ne fonctionne pas bien en 2002
il ne retourne pas à la couche précédente.

[SMadsen]

Hmmm, maybe I should start writing in Danish?

[sarcasm]But then I would probably not receive any help in an english speaking forum, would I now?[/sarcasm]

[Andrea]

ok...maybe to much work than i can't see..

but i have this code..to anable reactor...

Code: [Select]


(defun c:HTz ()
 (if (CC_find_env);;detect if some variable is set
   (progn  
  (SDC_readSfile);;read other variables
  (setq BC1r T11r
           BC1 T11
  );;redefine some variables
  (loadreactortype);;<---HERE LOAD REACTOR NOT WORKING
);;progn
);;if

(command "_DTEXT")
);;end HTz
 
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(defun loadreactortype ()
;;(alert "Reactor loaded")
(vl-load-com)
(vlr-command-reactor nil '((:vlr-commandWillStart . startCommand)))
(vlr-command-reactor nil '((:vlr-commandEnded . endCommand)))
(vlr-command-reactor nil '((:vlr-commandCancelled . cancelCommand)))
(vlr-command-reactor nil '((:vlr-commandFailed . failedCommand)))
)


Also i have made tests with alertbox....and the alertbos is shown..
but the reactor is not active..

why ?  (i'm tired)

Quit using "COMMAND" In reacor apps!

[daron]

To add to 7's comment. While it's bad to use command in reactors, it's even worse to use a command line that errors out to user control and doesn't take control back. Autocad needs to have control in order to react.

[SMadsen]

Se7en, the COMMAND is not within a callback so it's perfectly legal.

Andrea, the code you posted gives no clue to the problem, except that CC_FIND_ENV probably returns nil so that LOADREACTORTYPE will never be called.

When you get it working, I hope you are aware of the fact that the way it is written, it will add reactors each time C:HTZ is called (which can become very unpleasant).
