I would like to simplify this by getting the specific CStatusBar pane
window handle so I can take control of the attributes.

I dont think each status bar pane is a window by itself (unless you
put one there). You can confirm it by using Spy++.

Yes, I finally noticed this using Spy++.

I am now using the CExtStatusBarControl at codeproject. I had to make
corrections to it to override the CStatusBar::SetPaneText() so that the
index is checked against the custom controls managed by the sub-class or
default to the base class.


For the newsgroups search archives, just in case future people come
across a similar need, the cool CStatusBar subclass at codeproject:

which allows you to add controls to the status bar, it did not have
the logic to update the text pane (i.e, online timer) with the
inherited base function:

   BOOL SetPaneText(int nIndex, LPCTSTR lpszNewText, BOOL bUpdate = 1);

The subclass keeps/manages a different array for the controls vs the
pane indicators.

This SetPaneText wrapper added to the subclaas resolves it:

BOOL CExtStatusControlBar::SetPaneText(int nIndex,
                                        LPCTSTR lpszNewText,
                                        BOOL bUpdate)
    if( nIndex < m_nCount && nIndex >= 0 ){
       _STATUSBAR_PANE_ pane;
       if (PaneInfoGet(nIndex, &pane)) {
          for ( int i = 0; i < m_arrPaneControls.GetSize(); i++ ){
             if (m_arrPaneControls[i]->nID == pane.nID) {
                _STATUSBAR_PANE_CTRL_ *pPaneCtrl = m_arrPaneControls[i];
                if( pPaneCtrl ) {
                   return TRUE;
                return FALSE;
          return CStatusBar::SetPaneText( nIndex, lpszNewText, bUpdate);
    return FALSE;

Here is an implementation example:

After normally adding your CStatusBar control to your MFC main frame,
change the member to:

       CExtStatusControlBar m_wndStatusBar;

And in the CMainFrame::OnCreate(CREATESTRUCT *cs), create a CStatic
control or any other control.

int CMainFrame::OnCreate(CREATESTRUCT *cs)
    if (CFrameWnd::OnCreate(cs) == -1) {
        return -1;

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

    // create a right aligned static control and
    // add to the end of status bar as the pane.

    const char *pText = "Wildcat!";

    CStatic *m_pWndLabel = new CStatic;
    UINT nPosition = m_wndStatusBar.GetCount();
    if (!m_pWndLabel->Create(_T("Wildcat!"),
       TRACE("Failed to create label control.\n");
       return -1;


    UINT nLabelId = m_pWndLabel->GetDlgCtrlID();

    if(!m_wndStatusBar.AddPane(nLabelId,nPosition)) {
       AfxMessageBox(_T("out of range or duplicate id"), MB_ICONERROR);
       return -1;

    int nIndex = m_wndStatusBar.CommandToIndex(nLabelId);
    m_wndStatusBar.SetPaneWidth(nIndex, 110);
    m_wndStatusBar.AddPaneControl(m_pWndLabel, nLabelId, true);

    return 0;

Now you can update it, like in a OnTimer handler to update the pane:

   m_wndStatusBar.SetPaneText(m_wndStatusBar.GetCount()-1, sztime);
