lisp for changing all objects in a block to layer "0"

Hi this one work so great,,, i like it so much... am seeking for one modification in this...

Block entities are perfectly changing to "0" layer, but Block remain in same layer i wanted block also to change in "Desired Layer" or "0" Layer...

And if possible Nested block and Nested Entities to "0" Layer or to "Desired Layer"

thanks

Ah, that's my mistake... Changed code is:

No. I you want to proceed blocks in blocks, try this code:

   (vlax-for subent (vla-item (vla-get-blocks adoc) blk-name)
     (if (wcmatch (strcase (vla-get-objectname subent)) "*BLOCK*")
       (setq res (append res (fun_get-block-subref-by-block (vla-get-name subent))))
       ) ;_ end of if

No. I you want to proceed blocks in blocks, try this code:

   (vlax-for subent (vla-item (vla-get-blocks adoc) blk-name)
     (if (wcmatch (strcase (vla-get-objectname subent)) "*BLOCK*")
       (setq res (append res (fun_get-block-subref-by-block (vla-get-name subent))))

Thanks kpblc ,very nice! but I find that，color attribute change from bylayer to byblock,

Can anybody help in excluding the defpoints layer from the selection change?

This thread is a good example of the point I'll make ...

Is there a way to highlight the post with the best working code?

I copy/pasted this code, I forgot which version of the code. And I added some code (xref layers were still being processed ...).

It's hard to add code, and let everybody know what I did, because in the mean time other changes have been made.

I understand this is a forum (it's not Github or so) ... but still

Thank you for this Was helpful for me as well in 2016 June

Someone commented that the lisp that KPBLC created was the best thing since flushing toilets.  I'd go further, I think it's the best thing since sliced bacon, and I really cannot believe that it's taken me so long to find this routine. 

Dealing with dwg exports from Archicad, this will save me a massive amount of time.  Thank you very much indeed ...
