virtual BOOL CWnd::Create(
   LPCTSTR lpszClassName,
   LPCTSTR lpszWindowName,
   DWORD dwStyle,
   Const RECT& rect,
   CWnd* pParentWnd,
   UINT nID,
   CCreateContext* pContext = NULL
);




一 工具栏的使用



	1. MFC工具栏相关 


		CToolBar - 父类是CControlBar , 提供了与框架窗口相关的支持

		CToolBarCtrl  - 父类是 CWnd  对Win32下的ToolBar控件进行封装

		在MFC中, 一般使用CToolBar创建工具栏, 如果要进行更多工具栏的操作, 
		需要使用GetToolBarCtrl函数获取该工具栏的CToolBarCtrl类


	2.工具栏的使用
	  2.1 创建
		2.1.1 添加工具栏资源
		2.1.2 添加CToolBar    头文件   afxext.h
		2.1.3 创建工具栏
			Create 和 CreateEx
		2.1.4 
			LoadToolBar 加载工具栏资源

	  2.2 工具栏的停靠

		2.2.1 工具栏支持停靠   EnableDocking
		2.2.2 框架窗口停靠支持  CFrameWnd::EnableDocking
		2.2.3 停靠工具栏   DockToolBar


	3.工具栏显示和关闭



二 视图 View


	//WM_COMMAND   逐层向下(子窗口)派发消息
	WM_COMMAND消息处理,
		WM_COMMAND消息------>顶层窗口(Frame)--->OnWndMsg()--->
		OnCommand-->OnCmdMsg-->逐层派发


	可以使用 SetActiveView 将view设置成当前的活动视图
