Hi,

Have you tried with

ON_UPDATE_COMMAND_UI(ID_STATUSBAR_CONFIG, OnUpdateStatusBarText)

Regards,
Paresh.

Hello,

i'm writing a Data acquisition software. when i start the recording i
wanted to show the elapsed time in the status bar and once the
recording is stopped, the status bar should show "Rec Stopped"

My code is as follows

static UINT BASED_CODE indicators[] ={
    ID_SEPARATOR, // status line indicator

    ID_STATUS_BAR_SAVE,
    IDS_STATUS_MEASURE,
    ID_INDICATOR_ONLINE,
    ID_STATUSBAR_CONFIG,

};

int CParentFrame::OnCreate(LPCREATESTRUCT lpCS){
    //if(CMDIFrameWnd::OnCreate(lpCS) == -1) return -1;
    if(CreateAndDockToolBar() == -1) return -1;
    m_pMenu = new CMenu();
    m_pMenu->LoadMenu("MAINMENU");
    CreateClient(lpCS,m_pMenu->GetSubMenu(0));
    //SetMenu(pMenu);
    size_t sizeIndicator;
    sizeIndicator = sizeof(indicators);
    //m_wndToolBar = new CToolBar();

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

    //CStatusBarCtrl &m_csb = m_wndStatusBar.GetStatusBarCtrl();
    if(CMDITabFrameWnd::CreateTabs() == -1)
        return -1;

    UINT nID, nStyle;
    int cxWidth;
    int nIndex = m_wndStatusBar.CommandToIndex(ID_STATUS_BAR_SAVE);
    m_wndStatusBar.GetPaneInfo(nIndex, nID, nStyle, cxWidth);
    m_wndStatusBar.SetPaneInfo(nIndex, nID, nStyle | SBT_OWNERDRAW,
        cxWidth);

    return 0;
}

void CParentFrame::UpdateStatusBarText(jcStr *ptrText){
    UINT uiPane;
    UINT uiStyle;
    int uiWidth;
    CRect rectPane;

    int nIndex = m_wndStatusBar.CommandToIndex(IDS_STATUS_MEASURE); //the
program crash in debug
                                                        //right here
or any way i used m_wndStatusBar

    m_wndStatusBar.GetPaneInfo(nIndex, uiPane, uiStyle, uiWidth);

    CDC *pDC;
    pDC = m_wndStatusBar.GetDC();
    pDC->SelectObject(m_wndStatusBar.GetFont());
    pDC->DrawText(_T(ptrText->ReturnStr()), -1, rectPane, DT_CALCRECT);
    m_wndStatusBar.ReleaseDC(pDC);
    m_wndStatusBar.SetPaneInfo(nIndex, uiPane, uiStyle,
rectPane.Width());
    m_wndStatusBar.SetPaneText(nIndex, ptrText->ReturnStr());

}
where jcStr is an object similar to CString

i created a thread which updates the string pointer every 1 second and
calls the above function to update the status bar.

also when i ran the same application on a different computer(the
release mode) then status bar would not show the elapsed time, while
it shows the same in my computer

please point me in the right direction
