How To Serailize collection class object

[adityarao31]

I have simple CLine class which has two member variables which store first and last point of line.I store set of drawn lines in CObArray .Now I want to save the set of lines which I have drawn on CView on save button. And Get All lines back on open button click. Means serialize and deserialize in and out of CObArray Collection class. I have tried as shown in code. but I get no values where I have mentioned in code.Thus enable to retrieve the saved drawing. Can any one help me on this issue? // Serialization3View.cpp : implementation of the CSerialization3View class // #include "stdafx.h" #include "Serialization3.h" #include "Serialization3Doc.h" #include "Serialization3View.h" #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // CSerialization3View IMPLEMENT_DYNCREATE(CSerialization3View, CView) BEGIN_MESSAGE_MAP(CSerialization3View, CView) //{{AFX_MSG_MAP(CSerialization3View) ON_WM_LBUTTONDOWN() ON_WM_LBUTTONUP() ON_WM_MOUSEMOVE() ON_COMMAND(ID_FILE_SAVE, OnFileSave) ON_COMMAND(ID_FILE_OPEN, OnFileOpen) //}}AFX_MSG_MAP // Standard printing commands ON_COMMAND(ID_FILE_PRINT, CView::OnFilePrint) ON_COMMAND(ID_FILE_PRINT_DIRECT, CView::OnFilePrint) ON_COMMAND(ID_FILE_PRINT_PREVIEW, CView::OnFilePrintPreview) END_MESSAGE_MAP() ///////////////////////////////////////////////////////////////////////////// // CSerialization3View construction/destruction CSerialization3View::CSerialization3View() { // TODO: add construction code here } CSerialization3View::~CSerialization3View() { } BOOL CSerialization3View::PreCreateWindow(CREATESTRUCT& cs) { // TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs return CView::PreCreateWindow(cs); } ///////////////////////////////////////////////////////////////////////////// // CSerialization3View drawing void CSerialization3View::OnDraw(CDC* pDC) { CSerialization3Doc* pDoc = GetDocument(); ASSERT_VALID(pDoc); int liCount = pDoc->GetLineCount(); if(liCount > 1) { int lipos; CLine* l; for(lipos = 0;lipos < liCount;lipos++) { l = pDoc->GetLine(lipos); l->Draw(pDC); } } // TODO: add draw code for native data here } ///////////////////////////////////////////////////////////////////////////// // CSerialization3View printing BOOL

Just prepare an instance of CArchive and call CObArray::Seraialize(CArchive&) :)
