Notas

ProcessInput is called to provide a component a full IDTSBuffer90 object containing rows from the upstream component. The columns contained in the buffer include those columns defined in the IDTSInputColumnCollection90 of the component. If the component has synchronous outputs, it also includes the columns added to the output column collection by the component, and all the columns in the output column collection of the components that are upstream from the component. Columns are located in a buffer row by using the FindColumnByLineageID method of the BufferManager.

ProcessInput is called repeatedly as the data flow task receives full buffers from the upstream components. The final call to the ProcessInput method is confirmed when the IsEndOfRowset property is true.
