IDirectorySearch::GetPreviousRow

The IDirectorySearch::GetPreviousRow method gets the previous row of the search result. If the provider does not provide cursor support, it should return E_NOTIMPL.

HRESULT GetPreviousRow( 
  ADS_SEARCH_HANDLE hSearchHandle
);

Parameters

hSearchHandle: [in] Provides a handle to the search context.

Return Values

This method returns the standard return values, as well as the following:

For other return values, see ADSI Error Codes.

Return Code	Description
S_OK	The previous row was successfully obtained.
E_NOTIMPL	The provider does not provide the cursor support for search.

Remarks

When the ADS_SEARCHPREF_CACHE_RESULTS flag is not set, only forward scrolling is permitted, because the client might not cache all the query results.

Example Code [C++]

hr = m_pSearch->ExecuteSearch(L"(&(objectCategory=user)(st=WA))", pszAttr, dwCount, &hSearch );
if ( SUCCEEDED(hr) )
{
   while(  m_pSearch->GetNextRow(hSearch)  != S_ADS_NOMORE_ROWS )
   {
	/* Get the data */
   }
   // Print it backward
   hr = m_pSearch->GetPreviousRow( hSearch );
   while( hr != S_ADS_NOMORE_ROWS  &&  hr != E_NOTIMPL)
   {
	/* Get the data */
   }
   m_pSearch->CloseSearchHandle(hSearch);
}
