m_objVideoWindow = m_objFilterGraph as IVideoWindow;
m_objVideoWindow.Owner = (int)panelPlay.Handle;
m_objVideoWindow.WindowStyle = WS_CHILD | WS_CLIPCHILDREN;

WS_CHILD 和 WS_CLIPCHILDREN 怎么定义的？我怎么调试报错：名称“WS_CHILD”在类或命名空间“WindowsApplication1.frmPlayMedia”中不存在

m_objVideoWindow.Owner = (int)panelPlay.Handle;
m_objVideoWindow.WindowStyle = WS_CHILD | WS_CLIPCHILDREN;
m_objMediaEvent = m_objFilterGraph as IMediaEvent;
m_objMediaEventEx = m_objFilterGraph as IMediaEventEx;
m_objMediaEventEx.SetNotifyWindow((int)this.Handle,WM_GRAPHNOTIFY,0);
m_objMediaPosition = m_objFilterGraph as IMediaPosition;
主要询问这几句的意思！

CleanUp()做一些清空操作!
updateSelect()更新几个按纽的状态(enable状态)

updateSelect();
