void CFloatWnd::OnRButtonUp(UINT nFlags, CPoint point) 
{
// TODO: Add your message handler code here and/or call default
CMenu m_Right;
m_Right.LoadMenu(IDR_MENU1);
CMenu *pSub = m_Right.GetSubMenu(0);
ClientToScreen(&point);
pSub->TrackPopupMenu(TPM_LEFTALIGN,point.x,point.y,this,NULL);

CDialog::OnRButtonUp(nFlags, point);
