IEnumVARIANT::Reset Method

None

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

There is no guarantee that exactly the same set of variants will be enumerated the second time as was enumerated the first time. Although an exact duplicate is desirable, the outcome depends on the collection being enumerated. You may find that it is impractical for some collections to maintain this condition (for example, an enumeration of the files in a directory).

The following code implements IEnumVariant::Reset. A complete example implementation of the IEnumVariant interface is available in the COM Fundamentals Lines sample (Enumvar.cpp).

STDMETHODIMP
CEnumVariant::Reset()
{
   m_lCurrent = m_lLBound;
   return NOERROR;
