请问：windows控件SysTreeView32模拟点击（无论双击或者左键单击）怎么做？
有人说需要WM_NCHITTEST，但是似乎还是没用
我连发了6个消息，都没有用
SendMessage(m_lefttreeview, WM_NCHITTEST, NULL, m_iconOrders);
PostMessage(m_lefttreeview, WM_LBUTTONDOWN, NULL, m_iconOrders);
PostMessage(m_lefttreeview, WM_LBUTTONUP, NULL, m_iconOrders);
PostMessage(m_lefttreeview, WM_LBUTTONDBLCLK, NULL, m_iconOrders);
PostMessage(m_lefttreeview, WM_NCHITTEST, NULL, m_iconOrders);
PostMessage(m_lefttreeview, WM_LBUTTONUP, NULL, m_iconOrders);
那种mouse_event的函数我能够实现此功能，但是此方案不太适合
