ActiveX DLL loading

Anonymous — Sun, 05 Jan 2003 18:10:11 GMT

I am having a problem getting my ActiveX DLL to load. I am using the
following code:

(setq obj (vlax-create-object "Steel.StlUtil"))

My file is called Steel.dll and i have 2 seperate class files:

Channel(channelform.cls)
StlUtil(utilities.cls)

when I run this code all I get is NIL after.

The dll file works fine when I refenence it inside a Visual Basic EXE
program.

Any help will be appricated
I am new at ActiveX and this my first attempt at this.

I am going to post the DLL fine in customer files NG.

Thanks.

Try this instead.

(setq *Application* (vlax-get-acad-object))
(setq obj (vla-getinterfaceobject *Application* "Steel.StlUtil"))

You may also want to note that vlax-invoke-method does not appear to work.
Instead, use vlax-invoke.

I believe the latter method has been deprecated, but since it is the only
one I can get to work, it is what I use.

I am now getting a different error:

; error: Automation Error. Problem in loading application

Any idea what could be causing this? Does this mean my DLL might be
incorrect?

Thanks.

Are you certain "Steel" is the correct library name?

I doubt there is anything wrong with your DLL, since, as you mentioned
before, it works fine in VB.

Did you call (vl-load-com) before you tried to create the object?
