如何创建ActiveX's m_hWnd HWND，同时使用InnerHTML生成对象

How to create ActiveX's m_hWnd HWND while generating an object using InnerHTML

本文关键字：HWND hWnd 对象 InnerHTML 创建 何创建 ActiveX      更新时间：2023-09-26

我使用以下JS代码创建一个新的ActiveX对象

        var playerDiv = document.createElement("div");
        playerDiv.style.border = "1px solid red";
        var size = 200 + 20 * index;
        playerDiv.style.width = 200 + 20 * index + "px";
        playerDiv.style.height = 200 + 20 * index + "px";
        playerDiv.setAttribute("id", 'divPlayer' + index);
        var str = '<object id="player' + index + '" classid="CLSID:69A1BC06-C88F-4849-81E7-DB0AB0628819" width="' + size + '" height="' + size + '"></object>';       
        playerDiv.innerHTML = str;
        divViewPort.appendChild(playerDiv);

而playerDiv是一个简单的DIV标签。我的问题发生在innerHTML绑定期间，在绑定过程中，一个新的activeX对象被构造，但我没有收到来自JS引擎的调用来构造m_hWnd变量。查看遗留的代码，调用栈:

>   BCPlayer.dll!CSinglePlayer::CreateControlWindow(HWND__ * hWndParent, tagRECT & rcPos) Line 3207 C++
    BCPlayer.dll!ATL::CComControlBase::InPlaceActivate(long iVerb, const tagRECT * __formal) Line 1037  C++

    mshtml.dll!CElement::InjectTextOrHTML(enum CElement::Where,bool,unsigned short const * const,int)   Unknown
    mshtml.dll!CElement::put_innerHTML(unsigned short *)    Unknown

下面的函数:

CSinglePlayer::CreateControlWindow(HWND hWndParent, RECT& rcPos)

是对public CComControl<CSinglePlayer>的重写。执行CComControl<CSinglePlayer>::CreateControlWindow(hWndParent, rcPos);

一旦我们理解了遗留代码是如何工作的，在我的对象上使用的innerHTML，甚至从来没有执行过任何IOleObjectImpl函数，我设法模拟工作环境的唯一方法是通过引发OnClick()事件，迫使JS调用所需的函数并生成m_hWnd。我继承了以下接口/类:

    class /*ATL_NO_VTABLE*/
__declspec(uuid("{69A1BC06-C88F-4849-81E7-DB0AB0628819}"))
VPlayer :
    public CComObjectRootEx<CComMultiThreadModel>
    //, public ATL::CWindowImpl<VPlayer, ATL::CWindow, ATL::CFrameWinTraits>
    , public IObjectSafetyImpl<VPlayer, INTERFACESAFE_FOR_UNTRUSTED_CALLER |INTERFACESAFE_FOR_UNTRUSTED_DATA>
    , public CComCoClass<VPlayer, &__uuidof(VPlayer)>
    , public IDispatchImpl<IVPlayerControl>
    , public IDispatchImpl<IVPlayerSpeed>
    , public IDispatchImpl<IMetadata>
    , public IStreamingSourceCallback
    , public IPlayerEx
    , public CComControl<VPlayer>
    , public IOleControlImpl<VPlayer>
    , public IOleObjectImpl<VPlayer>
    , public IOleInPlaceActiveObjectImpl<VPlayer>
    , public IViewObjectExImpl<VPlayer>
    , public IOleInPlaceObjectWindowlessImpl<VPlayer>
    , public IQuickActivateImpl<VPlayer>

m_bWindowOnly = TRUE;

谢谢

根据朋友的建议，我们了解到.rgs文件被更改了。缺少以下代码片段:

        'TypeLib' = s '{02BED0E7-FD7C-49a5-A046-C1008BA2660B}'
        'MiscStatus' = s '0'
        {
        '1' = s '%OLEMISC%'
        }
