IDirectorySearch::GetNextRow method (iads.h)

The GetNextRow method gets the next row of the search result. If IDirectorySearch::GetFirstRow has not been called, GetNextRow will issue a new search beginning from the first row. Otherwise, this method will advance to the next row.

Syntax

HRESULT GetNextRow(
  [in] ADS_SEARCH_HANDLE hSearchResult
);

Parameters

[in] hSearchResult

Contains the search handle obtained by calling IDirectorySearch::ExecuteSearch.

Return value

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

For more information, see ADSI Error Codes.

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.

The directory provider may limit the maximum number of rows available in a search. For example, on a Windows domain, the maximum number of rows that will be provided in an Active Directory search is 1000 rows. If the search results in more than the row limit, a paged search must be performed to obtain all rows in the search. For more information about paged searches, see Paging with IDirectorySearch.

Examples

hr = m_pSearch->ExecuteSearch(L"(objectCategory=contact)", pszAttr, dwCount, &hSearch);
if(SUCCEEDED(hr))
{
    while(SUCCEEDED(hr = m_pSearch->GetNextRow(hSearch)))
    {
        if(S_OK == hr)
        {
            // Get the data.
        }
        else if(S_ADS_NOMORE_ROWS == hr)
        {
            // Call ADsGetLastError to see if the search is waiting for a response.
            DWORD dwError = ERROR_SUCCESS;
            WCHAR szError[512];
            WCHAR szProvider[512];

            ADsGetLastError(&dwError, szError, 512, szProvider, 512);
            if(ERROR_MORE_DATA != dwError)
            {
                break;
            }
        }
        else
        {
            break;
        }
    }
    
    m_pSearch->CloseSearchHandle(hSearch);
}
