How to grayout ribbon items

[Ahankhah]

Hi everybody,

as you can see, AutoCAD sometimes grays out true items in Ribbon or Toolbars (e.g. undo, redo, ...) when the associated commands are not allowed. Is there a way to control this ability via lisp?

Note: As documented, I know it is not possible. but I am searching some ways discovered by intelligent programmers of the forum (like Lee).

AFAIK - The only way to do what you ask via LISP, is to write a LispFunction Method in .NET, like this:

Direct link: Download the .DLL

 

** This utility was compiled for AutoCAD 2012, and requires .NET 4.0

RenderMan,

a great help

Thank you very much.

 

And a question not related to CAD. I didn't understand what AFAIK means.

I found the meaning:

 

AFAIK (As Far As I Know) = to the best of my knowledge (Internet chat slang)

 

Thank you RenderMan for the second thing you learned me.
