 void CQ700626Dlg::OnClickTree1(NMHDR *pNMHDR, LRESULT *pResult)
{
    // TODO: Add your control notification handler code here
    NM_TREEVIEW* pHdr = (NM_TREEVIEW*)pNMHDR;  
    *pResult = 0;  

    CPoint point;  
    UINT uFlag;  
    GetCursorPos(&point);  
    ScreenToClient(&point);  

    HTREEITEM item = m_tree.HitTest(point, &uFlag);  
    if (point.x > 30)
        MessageBox(_T("click the text"), NULL, 0U);
    else
        MessageBox(_T("click the box"), NULL, 0U);

    *pResult = 0;
