 工程H文件中定义CMyStatusBar    m_DlgMainStatusBar;
                             CProgressCtrl   m_DlgMainProgressBar;

工程应用CPP文件创建状态栏并在状态栏中创建进度条

    afx_msg void OnCreateStatusBar();
    afx_msg void OnWriteTextToStatusPanel(int nIndex,CString strText,COLORREF textClr);

在OnInitDialog中调用OnCreateStatusBar()

void CDoublePathWayReflowerControllerDlg::OnCreateStatusBar()
{CRect rcOfStatus;int   rcPanelWith;this->GetClientRect(rcOfStatus);if (!m_DlgMainStatusBar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_BOTTOM, AFX_IDW_STATUS_BAR)){TRACE0("Failed to create status bar1\n");AfxMessageBox(_T("OnCreateStatusBar->状态栏无法创建或创建失败！\n!"), MB_ICONERROR | MB_ICONINFORMATION);printf("OnCreateStatusBar->状态栏无法创建或创建失败！\n");}m_DlgMainStatusBar.SetIndicators(CStatusBar_Indicators, sizeof(CStatusBar_Indicators) / sizeof(UINT));m_DlgMainStatusBar.MoveWindow(0, rcOfStatus.bottom - 20, rcOfStatus.right, 20);rcPanelWith = rcOfStatus.right / SYSTEM_STATUSBAR_PANEL_NUM;m_DlgMainStatusBar.SetPanelNumber(SYSTEM_STATUSBAR_PANEL_NUM);m_DlgMainStatusBar.SetPaneInfo(SYSTEM_STATUSBAR_PANEL_NUM - 2, ID_PROGRESS_STATUS, SBPS_STRETCH | SBPS_NOBORDERS | SBPS_OWNERDRAW, rcPanelWith);m_DlgMainStatusBar.SetPaneText(0, STR_COMMUNICATION_PLC, SYSTEM_STATUS_COLOR_ALARM, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(1, STR_COMMUNICATION_PLC_PORT, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(2, STR_COMMUNICATION_PLC_BAUD, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(3, STR_COMMUNICATION_SERVERID, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(4, STR_COMMUNICATION_DATABIT, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(5, STR_COMMUNICATION_CHECKBIT, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(6, STR_COMMUNICATION_STOPBIT, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(7, STR_COMMUNICATION_MC408, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(8, STR_COMMUNICATION_PORT408, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(9, STR_COMMUNICATION_BAUD408, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(10, STR_COMMUNICATION_IPADDR408, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(11, STR_SYSTEM_TIME, SYSTEM_STATUS_COLOR, GetSysColor(COLOR_3DFACE));m_DlgMainStatusBar.SetPaneText(13, _T("RUN"), SYSTEM_STATUS_COLOR_RUN, GetSysColor(COLOR_3DFACE));for (int i = 0; i < SYSTEM_STATUSBAR_PANEL_NUM; i++){m_DlgMainStatusBar.SetPaneInfo(i, i,  SBPS_STRETCH /*| SBPS_NOBORDERS*/ | SBPS_OWNERDRAW, rcPanelWith);//m_DlgMainStatusBar.SetSinglePanelBackGroudColor(i,GetSysColor(COLOR_3DFACE));}CRect Lrect;m_DlgMainStatusBar.GetItemRect(SYSTEM_STATUSBAR_PANEL_NUM - 2, &Lrect);if (m_DlgMainProgressBar.m_hWnd){m_DlgMainProgressBar.MoveWindow(Lrect);}else{m_DlgMainProgressBar.Create(WS_CHILD | WS_VISIBLE | PBS_SMOOTHREVERSE | PBS_SMOOTH, Lrect, &m_DlgMainStatusBar, 3000);m_DlgMainProgressBar.SetRange(0, 100);m_DlgMainProgressBar.SetPos(50);}	
}

 Onsize（）

void CDoublePathWayReflowerControllerDlg::OnSize(UINT nType, int cx, int cy)
{CDialogEx::OnSize(nType, cx, cy);CRect rcNewWindow;int   rcPanelWithNew;this->GetClientRect(rcNewWindow);rcPanelWithNew = rcNewWindow.right / SYSTEM_STATUSBAR_PANEL_NUM;m_ResizeDlg.Move();RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);CWnd* m_pWND = AfxGetApp()->GetMainWnd();if (m_pWND!=NULL){}if (m_DlgMainStatusBar.m_hWnd){m_DlgMainStatusBar.MoveWindow(0, rcNewWindow.bottom - 20, rcNewWindow.right, 20);for (int i = 0; i < SYSTEM_STATUSBAR_PANEL_NUM; i++){m_DlgMainStatusBar.SetPaneInfo(i,0,0, /*i, SBPS_STRETCH | SBPS_NOBORDERS | SBPS_OWNERDRAW,*/ rcPanelWithNew);}CRect Lrect;m_DlgMainStatusBar.GetItemRect(SYSTEM_STATUSBAR_PANEL_NUM-2, &Lrect);if (m_DlgMainProgressBar.m_hWnd){m_DlgMainProgressBar.MoveWindow(Lrect);}}}

 OnWriteTextToStatusPanel(int nIndex, CString strText, COLORREF textClr)函数用来给状态栏Panel写入对应的文本，包括各自的文本颜色。

void CDoublePathWayReflowerControllerDlg::OnWriteTextToStatusPanel(int nIndex, CString strText, COLORREF textClr)
{CString strTitle = _T("");if (m_DlgMainStatusBar.m_hWnd){switch (nIndex){case 0:strTitle = STR_COMMUNICATION_PLC;break;case 1:strTitle = STR_COMMUNICATION_PLC_PORT;break;case 2:strTitle = STR_COMMUNICATION_PLC_BAUD;break;case 3:strTitle = STR_COMMUNICATION_SERVERID;break;case 4:strTitle = STR_COMMUNICATION_DATABIT;break;case 5:strTitle = STR_COMMUNICATION_CHECKBIT;break;case 6:strTitle = STR_COMMUNICATION_STOPBIT;break;case 7:strTitle = STR_COMMUNICATION_MC408;break;case 8:strTitle = STR_COMMUNICATION_PORT408;break;case 9:strTitle = STR_COMMUNICATION_BAUD408;break;case 10:strTitle = STR_COMMUNICATION_IPADDR408;break;case 11:strTitle = STR_SYSTEM_TIME;break;case 13:strTitle = SYSTEM_RUN_STASUS;break;default:break;}m_DlgMainStatusBar.SetPaneText(nIndex, strTitle+strText, textClr);}
