Returns the entry for a specific interface implemented in a class. 
 
Returns a pointer to a structure containing all of the interfaces implemented by a given class. 
 
This is GetTypeInfo, a member of class IVCLComObject. 
 
GetTypeInfo returns the object's type information.

Returns the size in bytes of each instance of the object type. 
 
Invoke implements the OLE Automation IDispatch Invoke function. 
 
This is the overview for the MethodAddress method overload. 
 
Returns the name of a class method by address.
