Context Menu Over ListCtrl Question

Hi,

  I have a list control usually with several entries.
I am trying to implement a context menu that will either
delete the selected entry or clear all the entries.

My main problem is that I can create the context menu and it comes up,
but it comes up everywhere on the form and I want it to come up only
when right clicked over the listview.

(And then I have to check if and which item is selected ...)

The code I'm using seems to work anywhere on the dialog. How can
I limit the popup menu to only work when over the list control?

Thanks very much...

code used so far:
//==============================================================
void CAstroCalcVC1Dlg::OnNMRClickList1(NMHDR *pNMHDR, LRESULT
*pResult)
{
    LPNMITEMACTIVATE pNMItemActivate =
reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);

    CMenu menu;
    VERIFY(menu.LoadMenu(IDR_POPUP_MENU));
    CMenu* pPopup = menu.GetSubMenu(0);

    int selected = m_list.GetNextItem(-1,LVNI_SELECTED);

    if(selected <0) {
        pPopup->EnableMenuItem(1,MF_GRAYED);
    }

    RECT rect;
    GetWindowRect(&rect);
    CPoint mousepos;
    GetCursorPos(&mousepos);
    pPopup->TrackPopupMenu(NULL,mousepos.x,mousepos.y, this);

    *pResult = 0;
}

//============================================================

//AND

void CAstroCalcVC1Dlg::OnContextMenu(CWnd* pWnd, CPoint point)
{
    // TODO: Add your message handler code here

    CMenu mnuPopup;
    mnuPopup.LoadMenu(IDR_POPUP_MENU);

    // Get a pointer to the button
    CListCtrl *pLV;
    pLV = reinterpret_cast<CListCtrl *>(GetDlgItem(IDC_LIST1));

    CRect rectLV;
    pLV->GetWindowRect(&rectLV);

    // Get a pointer to the first item of the menu
    CMenu *mnuPopupMenu = mnuPopup.GetSubMenu(0);
    ASSERT(mnuPopupMenu);

    // Find out if the user right-clicked the listctrl
    // because we are interested only in the listctrl
    if( rectLV.PtInRect(point) ) // Since the user right-clicked
the button, display the context menu
    {
    mnuPopupMenu->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,
point.x, point.y, this);

}
}
