Error Values
These methods return S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors.

Remarks
This string contains the fields (from the Bid table) used as criteria for selecting the auction winners when equal amounts are bid for an item. The string is added to the ORDER BY clause of a SQL string passed to the database for selecting the winners. The default string is "desired, modified_date". This means if two bidders bid the same amount, the bidder requesting more items wins. If still tied, the bidder placing the earliest bid wins.
