用CAcUiDockControlBar向CAD中加入自己的ControlBar出现问题，请各位高手急救！
<P>我创建了一个基于CAcUiDockControlBar的类，在类中创建自己的控件。加载到CAD后，让其自己停靠，但是停靠后的工具条高度无法所到。另外加载后CAD出现不停闪烁现象，请高手出招！</P><P> class CLayerDockControlBar : public CAcUiDockControlBar <BR>{<BR> DECLARE_DYNAMIC(CLayerDockControlBar)<BR>public:<BR> CLayerDockControlBar();<BR> <BR>public:<BR> virtual BOOL Create(CWnd* pParent, LPCSTR lpszTitle);<BR> <BR>protected:<BR> afx_msg int OnCreate (LPCREATESTRUCT lpCreateStruct);<BR> afx_msg void OnSize(UINT nType, int cx, int cy);<BR> DECLARE_MESSAGE_MAP()<BR> <BR> virtual void SizeChanged(CRect *lpRect, BOOL bFloating, int flags);<BR>public:<BR> CLayerManageBar *m_pWndLayerBar;<BR>};</P>
