Question

I have a serviced component installed in a COM+ server application. I want to create an instance from a remote client. The client needs to be able to specify the server machine’s name dynamically. How do I do this?

I tried using Activator:

            (XSLTransComponent.XSLTransformer)Activator.GetObject(                         typeof(XSLTransComponent.XSLTransformer),                         serverName                         ); 

But I get this:

System.Runtime.Remoting.RemotingException: Cannot create channel sink to connect to URL ‘server’. An appropriate channel has probably not been registered. at System.Runtime.Remoting.RemotingServices.Unmarshal(Type classToProxy, String url, Object data)

Do I need to register a channel? If so, how?

Another idea is to use Marshall.BindToMoniker, but how do I specify a moniker for a remote object hosted on COM+ on server x?

Eureka! This works:

string serverName = serverTextBox.Text; Type remote = Type.GetTypeFromProgID('XSLTransComponent.XSLTransformer', serverName); return (XSLTransComponent.XSLTransformer)Activator.CreateInstance(remote); 

Thanks to this question
