ICreateTypeInfo::AddImplType

HRESULT AddImplType(
  unsigned int  index,  
  HREFTYPE  hRefType    
);

Specifies an inherited interface, or an interface implemented by a component object class (coclass).

Parameters

index: Index of the implementation class to be added. Specifies the order of the type relative to the other type.
hRefType: Handle to the referenced type description obtained from the AddRefType description.

Return Value

The return value of the returned HRESULT is one of the following:

Return value	Meaning
S_OK	Success.
STG_E_INSUFFICIENTMEMORY	Out of memory.
E_OUTOFMEMORY	Out of memory.
E_ACCESSDENIED	Cannot write to the destination.
TYPE_E_WRONGTYPEKIND	Type mismatch.

Comments

To specify an inherited interface, use index = 0. For a dispinterface with Syntax 2, call ICreateTypeInfo::AddImplType twice, once with nindex = 0 for the inherited IDispatch and once with nindex = 1 for the interface that is being wrapped. For a dual interface, call ICreateTypeInfo::AddImplType with nindex = -1 for the TKIND_INTERFACE type information component of the dual interface.
