about ldata

Hi all

Is is possible to prevent a user from viewing ldata stored with an entity I means somehow hide the data so that vlax-ldata-list does not show the ldata stored.

Thanks.

You can make your Lisp file with a new application wizard by Visual Lisp Editor and that will cover all data of that Lisp file and will work normally....

Sorry Tharwat I could not understand what you mean can you please explain your reply.

Thanks.

In Visual Lisp Editor go menu->File->Make Application->New Application Wizard .........and follow up the steps untill you reach the end .

So the file that you will get will be secured and can be opened but with no Lisp codes at all .

try it ....

Good Luck

tharwat313, you are way off. He's wanting to hide ldata (similar to xdata), not encrypt his LISP file.

Yahhh

I thought he meant Lisp file data . if it is so . so he can not

Sorry for misunderstanding

No harm. However, he posted a function that references ldata. If you didn't recognize it, you should have looked it up in the Help files before responding.

> Tharwat, I agree with Alan: correct information far outweighs a quick response.

> GPD,

You cannot hide it in as much as preventing the user from extracting it (using LISP anyway). However you can disguise it....

eg.. using ASCII code shifting:

(defun eh? ( x )
 (vl-list->string
   (mapcar
     (function
       (lambda ( x ) (boole 6 x 42))
     )
     (vl-string->list x)
   )
 )
)

(eh? "y_XZXCYO\013")

What are some good uses for vlax-ldata? Why would you want to hide it?

Just trying to get a better understanding
