可以替代系统记事本的程序

首先建立基于类CEditView的单文档的工程Notepad，注意在MFC-AppWizard Step-4的Advanced中设定扩展名为txt。去掉工具栏（系统记事本里也没有），菜单按照系统的记事本来设计，并且ID用VC自带的设置，如“复制”ID为ID_EDIT_COPY。自己要加入字体的设置：

向CNotepadeView之中添加CFont类型的成员变量m_Font。为WM_CREATE消息添加映射函数。-System can replace Notepad procedures CEditView first category based on the works of a single document Notepad, attention in the MFC-AppWizard Step-4 in the Advanced settings extension txt. Remove the tool bar (system also does not Notepad), the menu system in accordance with the original design of the notebook, and bring ID with VC settings, such as " Copy"　ID for ID_EDIT_COPY. Themselves to join the font settings: CNotepadeView in to add CFont member variable of type m_Font. Add WM_CREATE message for the mapping function.
