Dialog changes with the pane changing

When you move pane, dialog should change its size automatically. if you need change layout of controls inside this dialog you can use our СXTPResizeDialog class.

I think we should use OnDockingPaneNotify message handling function.The code is below.

If you have better method or I have made some mistakes,please tell me,thank you!

LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{

  if (wParam == XTP_DPN_ACTION)
 {
   XTP_DOCKINGPANE_ACTION * pAction = (XTP_DOCKINGPANE_ACTION*)lParam;
   if (pAction->action==xtpPaneActionSplitterResized)  //Judge if the size of DockingPane is changed
  {
    CRect rcPane;   

    //Get the pane's ID and judge if it is what I want
    if (IDR_PANE==(pAction->pPane)->GetID())    

   {

     //Get the size of this pane,m_pPane is a pointer of pane
     rcPane=m_pPane->GetPaneWindowRect();      

     //make the dialog have the same size of pane
     m_pDlg->SetWindowPos(NULL, 0, 0, rcPane.Width(), rcPane.Height(), SWP_NOZORDER); 

   }   
  }
  return TRUE;
 }
 return FALSE;
}
