What’s the difference between ActiveX support and OCM? Can I generate my own COM components from Obsydian? How do I find out more about COM and OLE Automation? How do I find out more about VB and OLE Automation? How does MTS support fit into the OCM picture? How does Obsydian OCM inter-operate with CORBA? What are the cross platform issues with COM? How is component development different than ER?
