Re: Remote call to COM impersonating another user

It's set up for remote calls - I am able to make these calls remotely using
JIntegra. I guess what I need is to duplicate what JIntegra does. I get
authentication errors which leads me to believe that I need the mechanism
that sets up the call with credentials - in this case userID, password.

Well, you are more than likely going to have to call through DCOM/COM+.
Assuming you have it set up correctly on the other machine, and you have
an interface definition for the COM object you want to call, you can call
the GetTypeFromProgID (or GetTypeFromCLSID), using the overload which will
take a remote machine name. You would then create an instance of that
type through a call to CreateInstance on the Activator class, and cast to
your interface type.

Mind you, the semantics of making a remote call are different than just
making a regular COM call (activation contexts, instancing, and the like).

Do you already have the object set up for remote calls?

I need to call a COM object from a remote machine using C#. I also need to
pass on a different userID and password to the call. Has anyone done this?
I've used Java to do this using JIntegra, but the application I'm using
requires .NET.

Any advice?
