一些特殊字符的输入，在office软件中有特殊字符对话框：图
在搜狗输入法中输入特殊字符:图
这些特殊字符的开发都可以使用vc+添加控件来插入那些特殊字符。
let'start.
使用VC+从 CStatic 派生一个新的类,我命名为 CStcImageFont,头文件如下.
#pragma once// CStcImageFontclass CStcImageFont : public CStatic{ DECLARE_DYNAMIC(CStcImageFont)public: CStcImageFont(); virtual ~CStcImageFont();protected: DECLARE_MESSAGE_MAP()public: afx_msg void OnPaint();private: CDC *m_dcFont ; CBitmap *m_bmFont ; int m_iRowX ; int m_iRowY ; int m_iCurPos ; //垂直滚动条 CScrollBar* m_pScrollBar; CStringList m_strList ; CRect m_rClient ; CString m_strSelText ; double m_dXSpace ; double m_dYSpace ;public: void SetRowXY(int iRowX , int iRowY ) ; int GetRowX( void ) ; int GetRowY( void ) ; void SetCurPos(int iPos ) ; int GetCurPos(void ) ; void Init() ; CString GetSelText(void) ; afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct); afx_msg void OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar); afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point); afx_msg UINT OnNcHitTest(CPoint point); };
实现文件如下 CPP

其它特殊字符的添加，按代码改吧。
