如何给基于对话框的应用程序加入一个工具栏

        一、添加工具栏  
        1、先添加工具栏（IDR_TOOLBAR1）资源，并画好各个按钮。  
        2、在CXXXDlg类声名中添加成员变量   CToolBar   m_wndtoolbar;  
        3、 在CXXXDlg::OnInitDialog()   中添加如下代码    
        //添加一个平面工具条  
        if   (!m_wndtoolbar.CreateEx(   this,TBSTYLE_FLAT   ,     WS_CHILD   |   WS_VISIBLE   |   CBRS_ALIGN_TOP   |   CBRS_GRIPPER   |   CBRS_TOOLTIPS,  CRect(4,4,0,0))   || !m_wndtoolbar.LoadToolBar(IDR_TOOLBAR1)   )  
        {  
                TRACE0("failed   to   create   toolbar\n");  
                return   FALSE;  
        }  
        m_wndtoolbar.ShowWindow(SW_SHOW);  
        RepositionBars(AFX_IDW_CONTROLBAR_FIRST,   AFX_IDW_CONTROLBAR_LAST,   0);  

        二、为工具栏添加工具提示   
        1、 在CXXXDlg类定义中手工添加消息映射函数的定义，如下黑体部分    
        //{{AFX_MSG(CXXXDlg)  
        virtual   BOOL   OnInitDialog();  
        afx_msg   void   OnPaint();  
        afx_msg   BOOL   OnToolTipText(UINT,   NMHDR*   pNMHDR,   LRESULT*   pResult);  
        //}}AFX_MSG  
        DECLARE_MESSAGE_MAP()  

        2、在CXXXDlg.cpp添加函数的实现代码    
        //工具栏提示  
        BOOL   CXXXDlg::OnToolTipText(UINT,   NMHDR*   pNMHDR,   LRESULT*   pResult)  
        {  
                ASSERT(pNMHDR->code   ==   TTN_NEEDTEXTA   ||   pNMHDR->code   ==   TTN_NEEDTEXTW);  

                //   UNICODE消息  
                TOOLTIPTEXTA*   pTTTA   =   (TOOLTIPTEXTA*)pNMHDR;  
                TOOLTIPTEXTW*   pTTTW   =   (TOOLTIPTEXTW*)pNMHDR;  
                //TCHAR   szFullText[512];  
                CString   strTipText;  
                UINT   nID   =   pNMHDR->idFrom;  

                if   (pNMHDR->code   ==   TTN_NEEDTEXTA   &&   (pTTTA->uFlags   &   TTF_IDISHWND)   ||   pNMHDR->code   ==   TTN_NEEDTEXTW   &&   (pTTTW->uFlags   &   TTF_IDISHWND))  
                {  
                        //   idFrom为工具条的HWND    
                        nID   =   ::GetDlgCtrlID((HWND)nID);  
                }  

                if   (nID   !=   0)   //不为分隔符  
                {  
                        strTipText.LoadString(nID);  
                        strTipText   =   strTipText.Mid(strTipText.Find('\n',0)+1);  

                        #ifndef   _UNICODE  
                        if   (pNMHDR->code   ==   TTN_NEEDTEXTA)  
                        {  
                                lstrcpyn(pTTTA->szText,   strTipText,   sizeof(pTTTA->szText));  
                        }  
                        else  
                        {  
                                _mbstowcsz(pTTTW->szText,   strTipText,   sizeof(pTTTW->szText));  
                        }  
                        #else  
                        if   (pNMHDR->code   ==   TTN_NEEDTEXTA)  
                        {  
                                _wcstombsz(pTTTA->szText,   strTipText,sizeof(pTTTA->szText));  
                        }  
                        else  
                        {  
                                lstrcpyn(pTTTW->szText,   strTipText,   sizeof(pTTTW->szText));  
                        }  
                        #endif  

                        *pResult   =   0;  

                        //   使工具条提示窗口在最上面  
                        ::SetWindowPos(pNMHDR->hwndFrom,   HWND_TOP,   0,   0,   0,   0,SWP_NOACTIVATE|  
SWP_NOSIZE|SWP_NOMOVE|SWP_NOOWNERZORDER);    
                        return   TRUE;  
                }  
                return   TRUE;  
        }  

        3、在CXXXDlg.cpp中添加消息映射,请看如下代码中的黑体部分    
        BEGIN_MESSAGE_MAP(CXXXDlg,   CDialog)  
        //{{AFX_MSG_MAP(CXXXDlg)  
        ON_WM_PAINT()  
        ON_NOTIFY_EX(   TTN_NEEDTEXT,   0,   OnToolTipText   )  
        //}}AFX_MSG_MAP  
        END_MESSAGE_MAP()
