  At first,thanks for your great work!
  Just add one line to the demo programm,you can prevent user from manipulating the original mainframe window during
  printpreview:

  void CGridCtrl::PrintPreview()
  {
  if (m_bPrintPreview)
  {
  AfxGetApp()->m_pMainWnd->SetFocus();
  return;
  }

  CFrameWnd* pOldFrame=(CFrameWnd*)AfxGetThread()->m_pMainWnd;
  pOldFrame->ShowWindow(SW_HIDE); //added by eric

  ...
  }

  As you can see,before we replace the original mainframe
  window,just hide it,so the user cannot manipulate it
  anymore untill they close the preview window.
