get AeccApplication from DLL

Hi,
I have a sub called DX in a DLL:
Sub DX(Application As Object)
Set ThisDrawing = Application.ActiveDocument
'Do stuff here
end sub

I am calling it using a lisp routine:
(defun c:test ()
(vl-load-com)
(setq acadapp (vlax-get-acad-object))
(setq obj (vlax-invoke-method acadapp 'GetInterfaceObject "Common.clsTest"))
(vlax-invoke obj 'DX acadapp)
)

What should I do to invoke a AeccApplication? In order to use AeccApplication objects, I would probably pass a second attribute to my DX routine, right?
Thanks,
Mike

 

First you need to initialize the AecBaseDocument: the Lisp syntax for 2005
would be:

(setq acadapp (vlax-get-acad-object)
ret (vlax-invoke acadapp "getinterfaceobject"
"AecX.AecBaseDocument.4.5")
doc (vlax-get acadapp "ActiveDocument")))

(vlax-invoke ret "init" doc)

;end code

Now the active document object "points" to the AecBaseDocument which
contains all the AEC container stuff. Remember that the Schedule and
Structural Objects are not included in the BaseDocument Object and need to
be initialized seperately. So I don't think you need the VB part - all of
the Aec Object Data is accessible through LISP.

The only downside is, as of 2005, Aec Objects are not exposed to the
ObjectDBX interface object - so you'll need to access those through the
dictionaries.
