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 : public CObject?{private :LOGPEN m_logPen; //画笔COLORREF m_crBackColor;CArrayCPoint, CPoint m_PointArray; //标记类对应框public:intGetSize();CPointGetPoint(int pos);voidDrawLine(CDC *pDC,CPoint pt1,CPoint pt2,CRect rc);voidDrawBackGround(CDC *pDC,CRectrect);voidDrawPoint(CDC *pDC, CRectrect);voidSetWidth(intiWidth);COLORREF GetColor();voidSetColor(COLORREF color);COLORREF GetBkColor();voidSetBkColor(COLORREF color);voidAddPoint(CPoint point);void Clear();CLine();virtual ~CLine();virtual void Serialize(CArchive ar);CLine operator=(CLine src);DECLARE_SERIAL(CLine)??}; 实现文件：Line.cpp //////////////////////////////////////////////////////////////////////// Line.cpp: implementation of the CLine class.////////////////////////////////////////////////////////////////////////#include stdafx.h#include TestAdo.h#include Line.h#ifdef _DEBUG#undef THIS_FILEstatic char THIS_FILE[]=__FILE__;#define new DEBUG_NEW#endifIMPLEMENT_SERIAL(CLine,CObject,1)CLine::CLine(){Clear();}CLine::~CLine(){}//重写 =CLine CLine::operator=(CLine src){if(this!=src){m_logPen = src.m_logPen;m_crBackColor = src.m_crBackColor;}return *this;?}//串行化操作voidCLine::Serialize(CArchive ar){if (ar.IsStoring()){ar DWORD(m_crBackColor);ar.Write(m_logPen, sizeof(LOGPEN));}else{DWORD dw;ar dw; m_crBackColor = COLORREF(dw);ar.Read(m_logPen, sizeof(LOGPEN));}m_PointArray.Serialize(ar);}voidCLine::Clear(){m_crBackColor = RGB(255,255,255);m_logPen.lopnStyle = PS_SOLID;m_logPen.lopnWidth.x = 1;m_logPen.lopnWidth.y = 1;m_logPen.lopnColor = RGB(0, 0, 0);m_PointArray.RemoveAll();}voidCLine::AddPoint(CPoint point){m_PointArray.Add(point);}voidCLine::SetColor(COLORREF color){m_logPen.lopnColor = color;}COLORREF CLine::GetColor(){returnm_logPen.lopnColor;}voidCLine::SetBkColor(COLORREF color){m_crBackColor = color;}COLORREF CLine::GetBkColor(){returnm_crBackC
