SetCurSel() doesn't work

 

I want to change focused date, so I used SetCurSel() function.

However, it didn't work. Here is my code. Is there anyone who can point out the problem?

 

I'm using Xtreame ToolkitPro 2005 (10.3.1) on Windows XP Professional

 

==============================================

 

CXTPDatePickerControl wndDatePicker;
 
 CXTPWindowRect rcPopup(GetDlgItem(IDC_STARTDATE_SEARCH));

 CRect rc;
 wndDatePicker.GetMinReqRect(&rc);
 
 rc.InflateRect(0 ,0, 4, 4);
 rc.OffsetRect(rcPopup.right - rc.Width(), rcPopup.bottom);

 COleDateTime dt1(2008, 4, 1, 0, 0, 0);
 wndDatePicker.SetCurSel(dt1); // <= why it doesn't work?

 wndDatePicker.SetButtonsVisible(TRUE, FALSE);
 wndDatePicker.SetShowWeekNumbers(TRUE);

 CString strResult = _T("");

 if (wndDatePicker.GoModal(rc, this))
 {
  COleDateTime dtFrom;
  COleDateTime dtTo;

  if (wndDatePicker.GetSelRange(dtFrom, dtTo))
  {
   if (dtFrom == dtTo)
   {
    strResult.Format(_T("%4d-%02d-%02d"), 
     dtFrom.GetYear(), dtFrom.GetMonth(), dtFrom.GetDay());
   } else
   {
    // edit
    strResult.Format(_T("%4d.%02d.%02d - %4d.%02d.%02d"),
     dtFrom.GetYear(), dtFrom.GetMonth(), dtFrom.GetDay(),
     dtTo.GetYear(), dtTo.GetMonth(), dtTo.GetDay());
   }
  }
  else
   strResult = strCurrentText;
 }
 else
  strResult = strCurrentText;

 this->m_StartDateEdit.SetWindowText(strResult);
