Check if DVB Loaded from LISP 2

[CanonShooter]

In my Acad.lsp file, I am loading a DVB file. When I open another drawing, it tells me the DVB is already loaded. Is there a way in LISP to check for it being loaded, and skip the loading of it?

I tried a simple If(not "ABC.DVB")..... but it didn't work.

I read that whole thing. Very imformative. But it didn't solve my problem. I guess you can't unload a DVB. An ARX, yes. I need to unload an ARX, but I can't because it is locked after loading, and I got no idea how it got locked, or how to unlock it. I star'ed ya anyway...

From Borgunit's link, I gather that if you make a small change to how you load the dvb file you will avoid the error message and not need to check if it's loaded. Your load code is probably something like:

(command "-vbaload" "path & file name")

change this to:

(vl-vbaload "path & file name")

likewise you may want to change your "vbarun" command as suggested in the Cadalyst article.
