在Dialog中创建一个htmlview(CHtmlView类)区,实现浏览网页

1 派生一个CDocument类,并设置对话框为该类的友元,如:

class CXXDlg;

class CMyDocument : public CDocument
{
DECLARE_DYNCREATE(CMyDocument)

friend class CXXDlg;
public:
CMyDocument();
virtual ~CMyDocument();
#ifndef _WIN32_WCE
virtual void Serialize(CArchive& ar); // 为文档 I/O 重写
#endif
#ifdef _DEBUG
virtual void AssertValid() const;
#ifndef _WIN32_WCE
virtual void Dump(CDumpContext& dc) const;
#endif
#endif

protected:
virtual BOOL OnNewDocument();

DECLARE_MESSAGE_MAP()
};

2 派生一个CDocument类,并设置对话框为该类的友元,如:

class CXXDlg;

class CMyLogShView : public CHtmlView
{
DECLARE_DYNCREATE(CMyLogShView)

friend class CXXDlg;

protected:
CMyLogShView(); // 动态创建所使用的受保护的构造函数
virtual ~CMyLogShView();

public:
#ifdef _DEBUG
virtual void AssertValid() const;
virtual void Dump(CDumpContext& dc) const;
#endif

protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV 支持

DECLARE_MESSAGE_MAP()
};

3 在CXXDlg中定义一个创建HTMLVIEW的函数(当然你也可以不用定义):

CMyLogShView* CXXDlg::CreateMyLogShView(void)
{
    CCreateContext pContext;
    CWnd* pFramewnd = this;
    pContext.m_pCurrentDoc = new CMyDocument;
    pContext.m_pNewViewClass = RUNTIME_CLASS(CMyLogShView);

CMyLogShView *pMyLogShView =
(CMyLogShView *)((CFrameWnd*)pFramewnd)->CreateView(&pContext);

    if (pMyLogShView == NULL)
    {
        return NULL;
    }

pMyLogShView->ShowWindow(SW_NORMAL);

    CRect rectWindow;
    GetWindowRect(rectWindow);
    rectWindow.left -= 5;
    rectWindow.right += 15;
    rectWindow.top -= 22;   //这些是用来设置htmlview的位置的,可以任意设置个人认为合理的

pMyLogShView->MoveWindow(rectWindow);
return pMyLogShView;
}

我是在CXXDlg的OnInitDialog()函数中调用CreateMyLogShView()的,如下:

BOOL CXXDlg::OnInitDialog()
{
CDialog::OnInitDialog();

.....

......

// TODO: 在此添加额外的初始化

CMyLogShView* pMyLogShView;

pMyLogShView = CreateMyLogShView();

return TRUE; // return TRUE unless you set the focus to a control
}
