Oleaut32.dll Can Cause Incorrect Results in OLE Objects

ID: Q243472

The information in this article applies to:

Microsoft Visual Basic Standard, Professional, and Enterprise Editions, 32-bit only, for Windows, version 5.0

SYMPTOMS

When you pass SafeArray data from Microsoft Visual Basic to an OLE server, some data operations may not succeed or may return unexpected results.

CAUSE

Build 2.40.4275 of the Oleaut32.dll file incorrectly marks modified SafeArray data as unchanged. This causes certain data types to return unexpected results when the data is passed to an OLE server for modification.
