ICreateTypeInfo::AddImplType method (oaidl.h)

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

Syntax

HRESULT AddImplType(
  [in] UINT     index,
  [in] HREFTYPE hRefType
);

Parameters

[in] index

The index of the implementation class to be added. Specifies the order of the type relative to the other type.

[in] hRefType

A handle to the referenced type description obtained from the AddRefType description.

Return value

This method can return one of these values.

Return code	Description
S_OK	Success.
E_INVALIDARG	One or more of the arguments is not valid.
E_OUTOFMEMORY	Insufficient memory to complete the operation.
E_ACCESSDENIED	Cannot write to the destination.
STG_E_INSUFFICIENTMEMORY	Insufficient memory to complete the operation.
TYPE_E_WRONGTYPEKIND	Type mismatch.

Remarks

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