The code is

    CRect rectDummy;
    rectDummy.SetRectEmpty();
    if(!m_tab.Create(CMFCTabCtrl::STYLE_3D_VS2005, rectDummy, this, 1))
    {
    TRACE0("Failed to create output tab window\n");
    return -1;      // fail to create
    }

    m_tab.SetResizeMode(CMFCTabCtrl::RESIZE_NO);
    m_tab.SetLocation(CMFCTabCtrl::LOCATION_TOP);

    CRect rc;
    GetClientRect(rc);
    m_tab.MoveWindow(0, 200, rc.right, 200);

    const DWORD dwStyle = LBS_NOINTEGRALHEIGHT | WS_CHILD | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL;
    if (!m_wndOutputBuild.Create(dwStyle, rectDummy, &m_tab, 2) ||
        !m_wndOutputDebug.Create(dwStyle, rectDummy, &m_tab, 3) ||
        !m_wndOutputFind.Create(dwStyle, rectDummy, &m_tab, 4))
    {
        TRACE0("Failed to create output windows\n");
        return -1;      // fail to create
    }

    CString strTabName;
    BOOL bNameValid;

    // Attach list windows to tab:
    m_tab.AddTab(&m_wndOutputBuild, L"     First", (UINT)0);
    m_tab.AddTab(&m_wndOutputDebug, L"     Second", (UINT)1);
    m_tab.AddTab(&m_wndOutputFind,  L"     Third", (UINT)2);

    m_tab.init();

    return TRUE;  // return TRUE unless you set the focus to a control
                  // EXCEPTION: OCX Property Pages should return FALSE
} myTabCtrl.h
#pragma once

You can't do this with creating a check box window over the current CMFCTabCtrl.

My advice would be:

1. Implement your own Draw3dFlat or Draw3dTab functions. This function should draw the checkbox into the tab surface.
2. You may overwrite AdjustTabs to resize them to the size you want.
3. Implement your own OnLButtonDown handler that tracks if the user clicks into your checkbox...

You have all the original source code, it should be possible to implement this in using existing code.
