주의

The Script component developer does not use the ScriptBuffer class directly, but indirectly, through the derived classes in the BufferWrapper project item that represent the component's input and outputs.

The developer does not have to use the SetNull method, because the derived classes contain a <ColumnX>_IsNull property for each column that you can use to specify a null value.

The following sample code from the autogenerated BufferWrapper project item demonstrates how the Script component uses the SetNull method.

    Public WriteOnly Property [city_IsNull] As Boolean
        Set
            SetNull(1)
        End Set

End Property
