工学院实验报告实验项目：Web浏览器应用程序(网络编程实验） 计算机科学与技术 专业 0801 班姓 名： 于佳涛 学 号: 080102060051指导老师: 赵福祥 2011年 11 月实现目标:使用CHtmlView类可以实现一个应用程序,使之具有Wed浏览器的功能,包括浏览网页、前进、后退、返回主页和搜索功能。实验程序的技术要点：(1)利用MFC AppWizard生成应用程序框架. (2)掌握利用CHtmlView类开发Web客户机端程序的方法.程序代码及运行结果：1. 利用MFC AppWizard生成应用程序框架.(1) 应用程序类:Cyujiatao0051App,对应yujiatao0051.h和yujiatao0051.cpp文件.(2) 框架类:CMainFrame,对应MainFrm.h和MainFrm.cpp文件.(3) 文档类:C yujiatao0051Doc,对应yujiatao0051Doc.h和yujiatao0051.cpp文件.(4) HtmlView类:Cyujiatao0051View,对应yujiatao0051View.h和yujiatao0051.cpp文件.2. 程序代码(1) yujiatao0051View.cpp文件的实现 / yujiatao0051View.cpp : implementation of the C yujiatao0051View class/#include stdafx.h#include yujiatao0051.h#include yujiatao0051Doc.h#include yujiatao0051View.h#include MainFrm.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ C yujiatao0051ViewIMPLEMENT_DYNCREATE(CYujiatao0051View, CHtmlView)BEGIN_MESSAGE_MAP(CYujiatao0051View, CHtmlView)/AFX_MSG_MAP(CYujiatao0051View)ON_COMMAND(ID_BACK, OnBack)ON_COMMAND(ID_FOWARD, OnFoward)ON_COMMAND(ID_HOMEPAGE, OnHomepage)ON_COMMAND(ID_SEARCH, OnSearch)ON_COMMAND(ID_STOP, OnStop)ON_COMMAND(ID_UPDATE, OnUpdate)/AFX_MSG_MAP/ Standard printing commandsON_COMMAND(ID_FILE_PRINT, CHtmlView:OnFilePrint)END_MESSAGE_MAP()/ CYujiatao0051View construction/destructionCYujiatao0051View:CYujiatao0051View()/ TODO: add construction code hereCYujiatao0051View:CYujiatao0051View()BOOL CYujiatao0051View:PreCreateWindow(CREATESTRUCT& cs)/ TODO: Modify the Window class or styles here by modifying/ the CREATESTRUCT csreturn CHtmlView:PreCreateWindow(cs);/ CYujiatao0051View drawingvoid CYujiatao0051View:OnDraw(CDC* pDC)CYujiatao0051Doc* pDoc = GetDocument();ASSERT_VALID(pDoc);/ TODO: add draw code for native data herevoid CYujiatao0051View:OnInitialUpdate()CHtmlView:OnInitialUpdate();/ TODO: This code navigates to a popular spot on the web./ change the code to go where youd like.Navigate2(_T(/visualc/),NULL,NULL);/ CYujiatao0051View printing/ CYujiatao0051View diagnostics#ifdef _DEBUGvoid CYujiatao0051View:AssertValid() constCHtmlView:AssertValid();void CYujiatao0051View:Dump(CDumpContext& dc) constCHtmlView:Dump(dc);CYujiatao0051Doc* CYujiatao0051View:GetDocument() / non-debug version is inlineASSERT(m_pDocument-IsKindOf(RUNTIME_CLASS(CYujiatao0051Doc);return (CYujiatao0051Doc*)m_pDocument;#endif /_DEBUG/ CYujiatao0051View message handlersvoid CYujiatao0051View:OnBack() / TODO: Add your command handler code hereGoBack();void CYujiatao0051View:OnFoward() / TODO: Add your command handler code hereGoForward();void CYujiatao0051View:OnHomepage() / TODO: Add your command handler code hereGoHome();void CYujiatao0051View:OnSearch() / TODO: Add your command handler code hereGoSearch();void CYujiatao0051View:OnStop() / TODO: Add your command handler code hereStop();void CYujiatao0051View:OnUpdate() / TODO: Add your command handler code hereRefresh();void CYujiatao0051View:OnDocumentComplete(LPCTSTR lpszURL) / TODO: Add your specialized code here and/or call the base class(CMainFrame*)GetParentFrame()-SetPage(lpszURL);/CHtmlView:OnDocumentComplete(lpszURL);(2) MainFrm.h文件的实现 / MainFrm.h : interface of the CMainFrame class#if !defined(AFX_MAINFRM_H_46D187BD_7941_4BD8_9652_A780FF979164_INCLUDED_)#define AFX_MAINFRM_H_46D187BD_7941_4BD8_9652_A780FF979164_INCLUDED_#if _MSC_VER 1000#pragma once#endif / _MSC_VER 1000class CMainFrame : public CFrameWndprotected: / create from serialization onlyCMainFrame();DECLARE_DYNCREATE(CMainFrame)/ ClassWizard generated virtual function overrides/AFX_VIRTUAL(CMainFrame)virtual BOOL PreCreateWindow(CREATESTRUCT& cs);/AFX_VIRTUAL/ Implementationpublic:virtual CMainFrame();void OnNew();void SetPage(LPCTSTR lpszURL);#ifdef _DEBUGvirtual void AssertValid() const;virtual void Dump(CDumpContext& dc) const;#endifprotected: / control bar embedded membersCStatusBar m_wndStatusBar;CToolBar m_wndToolBar;CReBar m_wndReBar;CDialogBar m_wndDlgBar;/ Generated message map functionsprotected:/AFX_MSG(CMainFrame)afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);/ NOTE -
