WebBrowser控件：如何获取embed对象的参考？ [英] WebBrowser control : how to get a reference for an embed objet ?

问题描述

大家好，

我的目标是与嵌入在网页中的Flash对象进行交互。

My aim is to interact with a Flash Object embed in a Web Page.

我尝试使用C＃应用程序托管WebBrowser控件，导航到包含flash对象（如电影）的网页，但HtmlElement和HtmlDocument不允许转换< objet>标记到.NET Flash对象.....

I tried with a C# app that host a WebBrowser control, navigate to a web page containing a flash object (like a movie), but HtmlElement and HtmlDocument does not permit to transform the <objet> tag to a .NET Flash object .....

我知道我可以直接使用ShockwaveFlash ActiveX在.NET表单中，但根据我的需要，swf文件应保留在其上下文（网页）中。

I know that I can use the ShockwaveFlash ActiveX directly in a .NET form, but for my needs, the swf file should remain in its context (the web page).

如何获得"引用"？这个Flash对象？我想从我的C＃应用​​程序与它进行交互。

How can I get a "reference" to this Flash object ? I would like to interact with it from my C# app.

我在互联网上搜索了这么多个小时，我没有找到任何有意解决这个问题的东西。

I was searching so many hours on the Internet, I do not found anything interessting to solve this problem.

我甚至试图用C ++做到这一点：获取ActiveX的句柄（没关系，和Spy ++找到的句柄一样）但我无法将其转换为Windows窗体控件，因为Control.FromHandle（）不允许这样.... ....

I even tried to do it with C++ : getting the handle of the ActiveX (it's OK, same handle as Spy++ find) but I cannot transform it to a Windows Forms Control because Control.FromHandle() does not permit this....

有人请一个想法吗？

干杯，

Jack
