FIX: COM+ User Event Data Is Posted as SAFEARRAYs Fail (290611)


The information in this article applies to:

  • Microsoft COM+ 1.0
This article was previously published under Q290611

SYMPTOMS

When you use the COM+ user event mechanism, posting user events as SAFEARRAY does not work.

CAUSE

This problem occurs because the CComVariant::WriteToStream and CComVariant::ReadFromStream methods are used to marshal the variant. The CComVariant class does not handle variants of type VT_ARRAY. Because CComVariant::WriteToStream and CComVariant::ReadFromStream are used to marshal the variant, variants need special packaging for encoding and decoding.
