Can I get list of layers without opening drawing?

I have a situation where I need know what layers are in a drawing to know which one to open. As is I go through a dozen drawings to find the one I need. I know how to get a list from the current drawings but how do I get a list from a drawing I haven't opened yet?

dozen drawings to find the one I need. I know how to get a list from the current drawings but how do I get a list from a
drawing I haven't opened yet?

 

I don't think this will work for me. What I need is code to read layer names from a drawing that hasn't been opened yet and save it to a variable so I can manipulate it.

 

I've been programming with autolisp since the 80's and I've only used a little visual lisp that I've cut-n-pasted from others so I need help with the actual code. I know what I need to do but not how to do it.
I looked at the "Setting an attribute value in an unopened drawing" thread and I think that is the direction I need to go but I need help with the "; do your stuff here" part.

 

Why don't you take a swag at it, and post code..someone can fill-in the blanks..

Because it looks like I would have to use ObjectDBX and I don't know the first thing about it.

 

spykat,
If you browse over to http://www.cadvault.com/forums/showthread.php?t=9070
there is a thread that shows how to get views from one un-opened drawing to
the current one. In that thread is also the sample code to use to extract
the layers, blocks, textstyles.
