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
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 2.
