CGXBrowserGrid::MoveTo

virtual BOOL MoveTo(ROWCOL nRow);

nRow

Specifies the row id.

Return Value

Nonzero if successful; otherwise 0.

Remarks

Called to position the recordset to the given row. You should return FALSE if the positioning failed. See the attached example.

One reason the positioning could fail and that you should return FALSE is if nRow is larger than the record count.

Example

This sample demonstrates how MoveTo positions the current record by calling SetAbsolutePosition for a CDaoRecordset. If the positioning fails, the method returns FALSE.

BOOL CGXDaoGrid::MoveTo(ROWCOL nRow)
{
   CGXBrowseParam* pBrowseData = GetBrowseParam();
   if (m_pRecordset == NULL || !m_pRecordset->IsOpen() ||
      (long) (nRow-GetHeaderRows()) > OnGetRecordCount())
      return FALSE;
   long nRecord = GetRecordFromRow(nRow);
   long nCurrentRecord = m_pRecordset->GetAbsolutePosition();
   if (nCurrentRecord == nRecord)
      return TRUE;
   try
   {
      if (abs(nCurrentRecord-nRecord) > pBrowseData->m_lMoveRecordWaitCursor)
      {
         // display wait cursor
         CGXWaitCursor theWait;
         m_pRecordset->SetAbsolutePosition(nRecord);
      }
      else
         m_pRecordset->SetAbsolutePosition(nRecord);
   }
   catch (CDaoException* e)
   {
      e->Delete();
      return FALSE;
   }
   if (m_pRecordset->IsEOF())
   {
      pBrowseData->m_bEOFSeen = TRUE;
      return FALSE;
   }
   return TRUE;
}
