Put multiple CSliderCtrl in CMFCToolbar as toolbar buttons

I need multiple slider in MFCToolbar as its buttons. I can put slider in toolbar and shows slider. But I can't send slider position change message to parent toolbar or parent mainframe class. Also can not show tooltip for current position of slider.

These are steps to do it:

1. I derived a class clsMySlider from CSliderCtrl, overloaded its OnHScroll method
2. Derived a class from CMFCToolbarButtonclsMySliderButton and put an instance of clsMySlider inside it.
3. Added a method Initialize to clsMySliderButton and create instance of clsMySlider in this method
4. m_pParent and m_pToolbar are CWnd* of mainframe window and MFC toolbar pointers
5. Used CMFCToolbar::ReplaceButton to replace my first and second button of toolbar with 2 instances of clsMySliderButton
6. Overloaded OnHScroll method in MainFarme window to catch messages which Windows send to main frame

void clsMySlider::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar){    // TODO: Add your message handler code here and/or call default    ::PostMessage(m_pParent->GetSafeHwnd(), WM_SLIDER_HSCROLL, NULL, nPos);    ::PostMessage(m_pToolbar->GetSafeHwnd(), WM_SLIDER_HSCROLL, NULL, nPos);    CSliderCtrl::OnHScroll(nSBCode, nPos, pScrollBar);}void CMainFrame::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar){    // TODO: Add your message handler code here and/or call default        int dummyVar=nPos;    CFrameWndEx::OnHScroll(nSBCode, nPos, pScrollBar);}

but problem is OnHScroll never gets called in clsMySlider or CMainFrame window.

I appreciate your help.please let me know how to send position change events to parent toolbar and parent mainframe window and how can I show tooltip to show slider position.
