Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
By default, Object type arguments are marshaled as a VARIANT type, where the object type determines the VARTYPE value of the VARIANT. For example, an integer type passed as Object is marshaled as a VT_I4. In order to marshal the integer as a variant of type VT_ERROR, the integer can be wrapped in the ErrorWrapper before making the method call.
For more information on VT_ERROR, please see the existing documentation for VARENUM::VT_ERROR in the MSDN library.
