ITypeInfo::GetRefTypeOfImplType (Windows Embedded CE 6.0)

1/6/2010

This method retrieves the type description of implemented interface types for a component object class (coclass) or an inherited interface.

Syntax

HRESULT GetRefTypeOfImplType(
  unsigned int index, 
  HREFTYPE FAR* pRefType 
);

Parameters

  • index
    [in] Index of the implemented type whose handle is returned. The valid range is 0 to the cImplTypes member in the TYPEATTR structure.
  • pRefType
    [out] On return, pointer to a handle for the implemented interface (if any). This handle can be passed to ITypeInfo::GetRefTypeInfo to get the type description.

Return Value

The following table shows the return values for this function.

Remarks

If the TKIND_DISPATCH type description is for a dual interface, the TKIND_INTERFACE type description can be obtained by calling GetRefTypeOfImplType with an index of –1, and by passing the returned pRefType handle to GetRefTypeInfo to retrieve the type information.
