方法一：
1.添加成员变量CStatusBarCtrl m_StatusBar;
2.在OnInitDialog()中加入：
                  m_StatusBar.Create(WS_CHILD|WS_VISIBLE|SBT_OWNERDRAW, CRect(0,0,0,0), this, 0);

                  int strPartDim[3]= {100, 200, -1}; //分割数量
                  m_StatusBar.SetParts(3, strPartDim);

                  //设置状态栏文本
                  m_StatusBar.SetText("分栏一", 0, 0);
                  m_StatusBar.SetText("分栏二", 1, 0);
                  m_StatusBar.SetText("分栏三", 2, 0);
                  //下面是在状态栏中加入图标
                  m_StatusBar.SetIcon(1, 
                                SetIcon(AfxGetApp()->LoadIcon(IDR_MAINFRAME),
                                FALSE));//为第二个分栏中加的图标

方法二：
1.添加成员变量CStatusBar m_wndStatusBar;
2.在OnInitDialog()中加入：
                  static UINT indicators[] =
                  {
                                ID_SEPARATOR,                        // status line indicator
                                ID_INDICATOR_CAPS,              //CAP lock indicator.
                                ID_INDICATOR_NUM,               //NUM lock indicator.
                                ID_INDICATOR_SCRL,              //SCRL lock indicator.
                  };

                  if (!m_wndStatusBar.Create(this) ||
                                !m_wndStatusBar.SetIndicators(indicators,
                                  sizeof(indicators)/sizeof(UINT)))
                  {
                                TRACE0("Failed to create status barn");
                                return -1;         // fail to create
                  }

                  UINT nID;        //控制状态栏里面的分栏
                  m_wndStatusBar.SetPaneInfo(0,nID,SBPS_STRETCH|SBPS_NOBORDERS,100);      //返回值存nID中
                  m_wndStatusBar.SetPaneText(0,"就绪");

                  m_wndStatusBar.SetPaneInfo(1,nID,SBPS_NORMAL,100);
                  m_wndStatusBar.SetPaneText(1,"大写");

                  m_wndStatusBar.SetPaneInfo(2,nID,SBPS_POPOUT,100);
                  m_wndStatusBar.SetPaneText(2,"数字");

//                SetPaneInfo()函数的第三个参数的可选项如下：
//                The following indicator styles are supported:
//              SBPS_NOBORDERS     No 3-D border around the pane.
//              SBPS_POPOUT            Reverse border so that text "pops out."
//              SBPS_DISABLED         Do not draw text.
//              SBPS_STRETCH          Stretch pane to fill unused space. Only one pane per status bar can have this style.
//              SBPS_NORMAL            No stretch, borders, or pop-out.

//----------------让这个状态栏最终显示在对话框中-------------
                  RepositionBars(AFX_IDW_CONTROLBAR_FIRST,AFX_IDW_CONTROLBAR_LAST,0);
