Invoke an ActiveX DLL without registering it?

Invoke an ActiveX DLL without registering it?

I would like to invoke members of a local ActiveX DLL given its physical 
file path rather than using its CLSID. I don't want to register it at all (I 
have reasons, let's not discuss that).

What's the easiest way to pull this off?

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly 
overhead. -- RFC 1925

Re: Invoke an ActiveX DLL without registering it?

Is late binding supported with this method? I was hoping to implement this 
generically, facilitating user-entered script that calls upon it.

Sure. Late binding just means calling through IDispatch. This method 
does not care what interface you obtain on the newly created object, be 
it IDispatch or otherwise.

Re: Invoke an ActiveX DLL without registering it?

I'm pretty shy on C++ and I guess I'm looking for a more abstract 
methodology. It would be nice if there existed a DLL out there that I could 
call in script ..

Dim inv, obj
Set inv = CreateObject("SomeAXInvocator.Invocator")
Set obj = inv.CreateObjectFromFile("C:\My\Unregistered.dll", "ClassName")

Does nothing like that exist? I mean, if not, but it's doable to do it in 
C++, how hard would it be to produce the above implementation and share it 
with the world? If I have to do it with C++ then I'll do just that but I'd 
really rather not spend time on reinventing COM exposition like that. I'm 
much too busy, I have business objects to consume. Burrp.. :) :)

Not as far as I know, but it should be pretty easy to write one using 
the information you have received in this thread.

Note that such an object would be very insecure - you should never mark 
it safe for scripting, only trusted scripts should have access to it.

Re: Invoke an ActiveX DLL without registering it?

Easy is relative. The one and only time I worked with C/C++ was updating a 
JNI DLL to expose ActiveX to a Java class. It was already built, though, and 
I had a mentor to assist me. That was some five or so years ago.

I am up for the challenge, but I don't see this as "easy" at all. :)
