如何才能让IE浏览器安装调用未签名的ActiveX控件

该攻略需要分为两个部分：生成未签名的ActiveX控件和在IE浏览器中安装调用未签名的ActiveX控件。

生成未签名的ActiveX控件

在Visual Studio中创建一个ActiveX控件项目，并将其编译为未签名的DLL文件。

示例代码如下所示：

// MyActiveXCtrl.h

#pragma once

#ifdef MYACTIVEXCTRL_EXPORTS
#define MYACTIVEXCTRL_API __declspec(dllexport)
#else
#define MYACTIVEXCTRL_API __declspec(dllimport)
#endif

#include <afxwin.h>

// CMyActiveXCtrl

class MYACTIVEXCTRL_API CMyActiveXCtrl : public COleControl
{
    DECLARE_DYNCREATE(CMyActiveXCtrl)

public:
    virtual void OnDraw(CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid);
    virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
    virtual BOOL OnAmbientProperty(COleControlSite* pSite, DISPID dispid);
    virtual BOOL IsSubclassedControl();

protected:
    DECLARE_OLECREATE_EX(CMyActiveXCtrl)    // Class factory and guid
    DECLARE_OLETYPELIB(CMyActiveXCtrl)      // GetTypeInfo
    DECLARE_PROPPAGEIDS(CMyActiveXCtrl)     // Property page IDs
    DECLARE_OLECTLTYPE(CMyActiveXCtrl)

    // Message maps
    DECLARE_MESSAGE_MAP()

    // Dispatch maps
    DECLARE_DISPATCH_MAP()

    // Event maps
    DECLARE_EVENT_MAP()

    // Property prototypes
    BOOL m_bTransparent;

    // Property accessors
    BOOL GetTransparent();
    void SetTransparent(BOOL bNewValue);
};

// MyActiveXCtrl.cpp

#include "pch.h"
#include "MyActiveXCtrl.h"

// CMyActiveXCtrl

IMPLEMENT_DYNCREATE(CMyActiveXCtrl, COleControl)

// Message map

BEGIN_MESSAGE_MAP(CMyActiveXCtrl, COleControl)
    ON_WM_CREATE()
END_MESSAGE_MAP()

// Dispatch map

BEGIN_DISPATCH_MAP(CMyActiveXCtrl, COleControl)
END_DISPATCH_MAP()

// Event map

BEGIN_EVENT_MAP(CMyActiveXCtrl, COleControl)
END_EVENT_MAP()

// Property pages

// TODO: Add more property pages as needed.  Remember to increase the count!
BEGIN_PROPPAGEIDS(CMyActiveXCtrl, 1)
    PROPPAGEID(CMyActiveXCtrlPropPage::guid)
END_PROPPAGEIDS(CMyActiveXCtrl)

// Initialize class factory and guid

IMPLEMENT_OLECREATE_EX(CMyActiveXCtrl, "MYACTIVEXCTRL.MyActiveXCtrl.1",
    0x5c817bf0, 0x1f30, 0x40a1, 0x8a, 0x9c, 0xd5, 0x78, 0x40, 0xa6, 0x7, 0x8d)

// Type library ID and version

IMPLEMENT_OLETYPELIB(CMyActiveXCtrl, _tlid, _wVerMajor, _wVerMinor)

// Interface IDs

const IID IID_DMyActiveXCtrl = {0x583dfe98,0xecd6,0x47b2,{0xa0,0xdb,0xe2,0x29,0x70,0x26,0x94,0x9}};

// Control type information

IMPLEMENT_OLECTLTYPE(CMyActiveXCtrl, IDS_MYACTIVEXCTRL, _dwMyActiveXCtrlOleMisc,
    _DMyActiveXCtrl, _tlid, _wVerMajor, _wVerMinor)

// CMyActiveXCtrl::CMyActiveXCtrlFactory::UpdateRegistry -
// Adds or removes system registry entries for CMyActiveXCtrl

BOOL CMyActiveXCtrl::CMyActiveXCtrlFactory::UpdateRegistry(BOOL bRegister)
{
    if (bRegister)
        return AfxOleRegisterControlClass(
            AfxGetInstanceHandle(),
            m_clsid,
            m_lpszProgID,
            IDS_MYACTIVEXCTRL,
            IDB_MYACTIVEXCTRL,
            afxRegApartmentThreading,
            _dwMyActiveXCtrlOleMisc,
            _tlid,
            _wVerMajor,
            _wVerMinor);

    AfxOleUnregisterClass(m_clsid, m_lpszProgID);
    return TRUE;
}

// CMyActiveXCtrl::CMyActiveXCtrl - Constructor

CMyActiveXCtrl::CMyActiveXCtrl()
{
    InitializeIIDs(&IID_DMyActiveXCtrl, &IID_DMyActiveXCtrlEvents);
    // TODO: Initialize your control's instance data here.
}

// CMyActiveXCtrl::~CMyActiveXCtrl - Destructor

CMyActiveXCtrl::~CMyActiveXCtrl()
{
    // TODO: Cleanup your control's instance data here.
}

// CMyActiveXCtrl::OnDraw - Drawing function

void CMyActiveXCtrl::OnDraw(CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
    if (!pdc)
        return;

    DoSuperclassPaint(pdc, rcBounds);

    if (m_bTransparent)
        return;

    // TODO: Replace the following code with your own drawing code.

    pdc->FillRect(rcBounds, CBrush::FromHandle((HBRUSH) GetStockObject(WHITE_BRUSH)));
    pdc->Ellipse(rcBounds);
}

// CMyActiveXCtrl::DoPropExchange - Persistence support

void CMyActiveXCtrl::DoPropExchange(CPropExchange* pPX)
{
    ExchangeVersion(pPX, MAKELONG(_wVerMinor, _wVerMajor));
    COleControl::DoPropExchange(pPX);
}

// CMyActiveXCtrl::OnResetState - Reset control to default state

void CMyActiveXCtrl::OnResetState()
{
    COleControl::OnResetState();  // Resets defaults found in DoPropExchange

    // TODO: Reset any other control state here.
}

// CMyActiveXCtrl::PreCreateWindow - Modify parameters for CreateWindowEx

BOOL CMyActiveXCtrl::PreCreateWindow(CREATESTRUCT& cs)
{
    cs.lpszClass = _T("STATIC");
    cs.style = WS_CHILD | WS_VISIBLE;
    return COleControl::PreCreateWindow(cs);
}

// CMyActiveXCtrl::OnAmbientProperty - Handle changes in ambient properties

BOOL CMyActiveXCtrl::OnAmbientProperty(COleControlSite* pSite, DISPID dispid)
{
    switch (dispid)
    {
        case DISPID_UNKNOWN:
        case DISPID_AMBIENT_BACKCOLOR:
        case DISPID_AMBIENT_DISPLAYNAME:
        case DISPID_AMBIENT_FONT:
        case DISPID_AMBIENT_FORECOLOR:
        case DISPID_AMBIENT_LOCALEID:
        case DISPID_AMBIENT_MESSAGEREFLECT:
        case DISPID_AMBIENT_SCALEUNITS:
        case DISPID_AMBIENT_TEXTALIGN:
        case DISPID_AMBIENT_USERMODE:
            InvalidateControl();
            break;

        case DISPID_AMBIENT_SHOWGRABHANDLES:
        case DISPID_AMBIENT_SHOWHATCHING:
        case DISPID_AMBIENT_UIDEAD:
        case DISPID_AMBIENT_USEVISUALSTYLE:
        case DISPID_AMBIENT_AUTOCLIP:
            break;

        default:
            return FALSE;
    }

    return TRUE;
}

// CMyActiveXCtrl::IsSubclassedControl - This is a subclassed control

BOOL CMyActiveXCtrl::IsSubclassedControl()
{
    return TRUE;
}

// CMyActiveXCtrl message handlers

int CMyActiveXCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (COleControl::OnCreate(lpCreateStruct) == -1)
        return -1;

    ModifyStyle(0, SS_CENTERIMAGE);  // Center bitmap
    return 0;
}

// CMyActiveXCtrl::GetTransparent - Getter for Transparent property

BOOL CMyActiveXCtrl::GetTransparent()
{
    return m_bTransparent;
}

// CMyActiveXCtrl::SetTransparent - Setter for Transparent property

void CMyActiveXCtrl::SetTransparent(BOOL bNewValue)
{
    m_bTransparent = bNewValue;
    InvalidateControl();
}

将控件的DLL文件上传至一个Web服务器上，以备后续安装调用。

在IE浏览器中安装调用未签名的ActiveX控件

在IE浏览器中打开Web服务器上传的DDL文件所在的URL，并等待该文件下载到本地。
在IE浏览器的地址栏输入“about:blank”，然后按下回车键，打开一个空白页面。
在空白页面上右击，选择“属性”，在出现的属性窗口中找到“自定义”选项卡，然后点击“新建”按钮，在“名称”字段中输入ActiveX控件的名称，如“MyActiveXCtrl”，在“值”字段中输入控件的CLSID，如“{5C817BF0-1F30-40A1-8A9C-D57840A6078D}”。
在空白页面上添加一个脚本标记，用于创建和调用控件的实例。

示例代码如下：

<html>
<head>
<title>My ActiveX Control Test Page</title>
<script language="javascript">
<!--
function load()
{
   var control = new ActiveXObject("MYACTIVEXCTRL.MyActiveXCtrl.1");
   document.body.appendChild(control);
}
//-->
</script>
</head>
<body onload="load()">
</body>
</html>

保存该空白页面，并再次在IE浏览器中打开该页面，即可看到控件已经被成功安装和调用。

另一个示例：

在IE浏览器中输入以下代码，将未签名的ActiveX控件作为object标记插入到HTML页面中:

<object id="myactivexctrl" codebase="http://mywebserver/myactivexctrl.dll" classid="clsid:5C817BF0-1F30-40A1-8A9C-D57840A6078D"></object>

在JS代码中调用ActiveXObject来创建控件的实例，示例代码如下所示:

var control = new ActiveXObject("MYACTIVEXCTRL.MyActiveXCtrl.1");
document.getElementById("myactivexctrl").appendChild(control);

该攻略不建议用于在生产环境中使用，因为在实际部署时，未签名的ActiveX控件会对系统安全性带来潜在的风险。
