1、Ado实现C++对象的存取作者：江上飞鸟下载源代码　　其实我最讨厌写东西了，最近忙死了，呵呵，前一段时间在做一个图形程序时，需要把C++对象保存到数据库里，刚开始真让我头疼啊，琢磨了一个下午，终于给做出来了，废话不说了，还是把自己的一些体会与各位同任一起分享！！！！一、新建一个继承于CObject的子类CLine；头文件：Line.hclassCLine:publicCObject?{private:LOGPENm_logPen;//画笔COLORREFm_crBackColor;CArraym_

2、PointArray;//标记类对应框public:intGetSize();CPointGetPoint(intpos);voidDrawLine(CDC*pDC,CPointpt1,CPointpt2,CRectrc);voidDrawBackGround(CDC*pDC,CRectrect);voidDrawPoint(CDC*pDC,CRectrect);voidSetWidth(intiWidth);COLORREFGetColor();voidSetColor(COLORREFcolor);COLORREFGetBk

3、Color();voidSetBkColor(COLORREFcolor);voidAddPoint(CPointpoint);voidClear();CLine();virtual~CLine();virtualvoidSerialize(CArchive&ar);CLine&operator=(CLine&src);DECLARE_SERIAL(CLine)??};实现文件：Line.cpp////////////////////////////////////////////////////////////////////
