Subclass HeaderCtrl in ListCtrl

[VictorN]

That is the code that works for me for the standard CListCtrl:

void CSubItemCheckListCtrl::PreSubclassWindow() 
{
	m_header.SubclassDlgItem(0, this);

	CListCtrl::PreSubclassWindow();
}

where m_header is of the type derived from CHeaderCtrl and CSubItemCheckListCtrl is derived from CListCtrl
