Linking DLL for lisp

[Laurie Comerford]

Hi,

I have a DLL containing a number of string handling functions which I wish to call from lisp.

How do I go about linking the DLL to my lisp program ?

How do I call it ?

In VBA, I simply attach it using the [Tools][References]

Then I have lines such as:

Dim Mydll As MydllProgram

Set Mydll = New MydllProgram
ReturnString = Mydll (PassedString)

Something like this

(setq acd (vlax-get-acad-object))
(setq srv (vlax-invoke acd "getinterfaceobject" "your dll.class")) (setq ret (vlax-invoke srv "your dll function"))
