/** @attribute DispIdAttribute(13) */

function PreExecute ()

Hinweise

Component developers should factor as much functionality into PreExecute as possible because it is called only once per component execution, unlike ProcessInput, which is called once for each input buffer. Components should locate the indexes of their input and output columns in the IDTSBuffer90 by calling the FindColumnByLineageID method of the BufferManager.
