void CCustomToolTipCtrl::OnShow(NMHDR* pNMHDR, LRESULT* pResult)
{
 m_nCurrID = CWnd::FromHandle ((HWND)pNMHDR->idFrom)->GetDlgCtrlID ();

 switch (m_nCurrID)
 {
 case IDOK:
  m_strDesrciption = _T("OK Button description...");//基本描述
  break;

 case IDCANCEL:
  m_strDesrciption = _T("Cancel Button description...");

  m_strDesrciption.Empty ();
 }

 CBCGPToolTipCtrl::OnShow (pNMHDR, pResult);
}

 

BOOL CCustomToolTipCtrl::OnDrawIcon (CDC* pDC, CRect rectImage)
{
 UINT uiBmpResID = 0;

 switch (m_nCurrID)
 {
 case IDOK:
  uiBmpResID = IDB_OK;
  break;

 case IDCANCEL:
  uiBmpResID = IDB_CANCEL;
  break;
 }

 if (uiBmpResID == 0)
 {
  return FALSE;
 }

 CBCGPToolBarImages image;
 image.Load (uiBmpResID);
 image.SetSingleImage ();
 image.DrawEx (pDC, rectImage, 0);

 CMenu* pSysMenu = GetSystemMenu(FALSE);//在系统菜单里增加一个新项
