SetButtonInfo and GetItemRect replacements?

Hi,

Can anybody tell me what are the replacement functions in Codejock 10.4.2 for SetButtonInfo and GetItemRect ?

Previously I am deriving my class from CXTToolBar and as per present implementation I am deriving my class from CXTPToolBar.

My requirement is to display combo box on Toolbar.
My previous code is as follows:-

    int nID=ID_PRIMARY_VIEW_COMBO;
    int nDropHeight=150;

  
    //SetButtonInfo(nIndex, nID, TBBS_SEPARATOR, w);

    CRect rect;
    //GetItemRect(nIndex, &rect);
    rect.top = 0;
    rect.bottom = rect.top + nDropHeight;
    if (!m_MasterViewListCombo.Create(                                 CBS_DROPDOWNLIST|CBS_AUTOHSCROLL|
WS_VISIBLE|WS_TABSTOP|WS_VSCROLL|WS_HSCROLL,
        rect, this, nID))
    {
        TRACE("Failed to create combo-box\n");
        return FALSE;
    }

Thanks in advance.
