Provides the methods that allow a DTC object to expose an object model to the hosting editor.
The RuntimeClassInforAuthor object exposes this interface. In Visual Basic, you need to declare a variable as this interface and then set the variable as a new instance of the object as shown below:
Dim rcia As IRuntimeClassInfoAuthor
Set rcia = New RuntimeClassInfoAuthor
For Visual C++ users, the IRuntimeClassInfoAuthor interface is implemented in an object of CLSID_RuntimeClassInfoAuthor.
A DTC that is creating a namespace creates one such object for each named object in its namespace, plus one to supply all top-level named items.
