SYMPTOMS

Posting a COM+ User event as a SAFEARRAY fails.

Back to the top

The IMtsEvents::PostEvent method takes a variant to post a user-defined event to the event sink. The CComVariant::WriteToStream and CComVariant::ReadFromStream methods are used to marshal this variant. Because CComVariant does not handle variants of type VT_ARRAY, sending a SAFEARRAY fails.
