Error in use of command

[Nima2018]

Hi members
I put a command in an opendcl button event click but in runtime an error
appears in Autocad prompts .
When I put this command outside of click event in top of my program it
works correctly , I want my Command to be inside of event click body
, what must I do ?

without knowing your exact code I think this FAQ may help you.

Hi,

You can not use command calls in events ( action_tile ) but you can replace the command with a function if available.
What's the command name that you are trying to use in the event?

Hi All
First of all, I thanks for your hints and reply , I learned a lot about "OPENDCL" programming in your points and links.
I really want to bring and execute an assembly that I have created in C# by the following commands :

Code Select Expand


(command "load" (findfile "myAssembly.dll")
(command "HTS")
;; HTS is command method in myAssembly.dll


When I cut (command "load" (findfile "myAssembly.dll") and paste it top of my program, all routines work but when this command is inside event button onclick,
at the prompt line I get and error !?
And in the case of the second command too , I must change it to below one to get rid of the error :

Code Select Expand


(princ)
(princ "\nType 'HTS' for execution")
(princ)

I think this is not a good method at all, and there must be a better and more effective one that I do not know about it.

Hi,
Try to use the function vla-sendcommand in lieu of command call.

Let me know if that function works for you.

Dear Tharwat Thanks for your advice.
I used the following instructions on the advice of you :

Code Select Expand



(vla-sendcommand "load" (filefind "myAssembly.dll"))
(vla-sendcommand "HTS")



And this time I saw this error on the command line:  ;error : bad argument type : VLA-OBJECT "load"

[Tharwat]

Please try it like the following:

Code Select Expand


(if (setq file (findfile "myAssembly.dll"))
  (vla-SendCommand (vla-get-ActiveDocument (vlax-get-acad-object)) (strcat "LOAD " file))
  )
