推荐答案

您可以通过IHTMLObjectElement ::对象方法访问的ActiveX的脚本接口的元素。在microsoft.public.inetsdk.programming.webbrowser_ctl新闻组搜索IShockwaveFlash更多这方面的信息。

You can access the ActiveX's scripting interface from the element via the IHTMLObjectElement::object method. Search IShockwaveFlash in the microsoft.public.inetsdk.programming.webbrowser_ctl newsgroup for more information on this.

如果您使用的是Windows窗体，HTML元素的接口通过的 HtmlElement.DomElement 。您可以添加引用microsoft.mshtml并投DomElement到IHTMLObjectElement，然后获取它的对象属性和转换为IShockwaveFlash。

If you are using Windows Forms, html element's interface is exposed via HtmlElement.DomElement. You can add a reference to microsoft.mshtml and cast DomElement to IHTMLObjectElement, then obtain its object property and cast to IShockwaveFlash.

在ATL的code看起来像这样

In ATL the code looks like this

#import   "flash.dll"   raw_interfaces_only

CComPtr<IDispatch>   htmlElement;   
CComPtr<IDispatch>   activeXObject;       
hr   =   GetElement(elementIdString,   &htmlElement);   
if   (htmlElement!= NULL)   
{   
    CComQIPtr<IHTMLObjectElement>   htmlObjectElement(htmlElement);
    if   (htmlObjectElement!= NULL)   
    {    
        htmlObjectElement->get_object(&activeXObject);   
        CComQIPtr<ShockwaveFlashObjects::IShockwaveFlash,   &IID_IUnknown>   flashViewer(spdispActiveXObject);     
        if(flashViewer!=NULL)
        {
            //do something on the flash
            CComBSTR movie;
            flashViewer->get_Movie(&movie);
        }
    }   
}
