FIX: You may receive an access violation error message when you compile a Visual Basic .NET 2003 project that passes a user-defined type as a variant to a COM+ component (833554)
The information in this article applies to:
SYMPTOMSIn Microsoft Visual Basic .NET 2003, if you pass
a user-defined type by reference from a routine in a Microsoft COM+ component that is in a project, you may receive an access violation error message when you compile the
project.CAUSEThis behavior occurs when a user-defined type is stored by
value in a variant and then the variant is passed by reference to an InProcess Microsoft Component Object Model (COM) component. When the routine returns and the reference to the variant is freed,
the ByValue user-defined type is also freed. Subsequent calls to the
user-defined type will throw an access violation exception because it was
incorrectly freed. RESOLUTIONHow to obtain the hotfixThis issue is fixed in the Microsoft Windows 2000 COM+ 1.0 Hotfix Package 30.
