FIX: COM+ User Events That Are Posted as SAFEARRAYs Do Not Work (297699)


The information in this article applies to:

  • Microsoft COM+ 1.0
This article was previously published under Q297699

SYMPTOMS

Posting a COM+ User event as a SAFEARRAY fails.

CAUSE

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.

RESOLUTION
