【API求教】C#根据flash句柄获取网页内flash的对象
根据句柄获取网页内flash的对象
首先我已经获取了flash的句柄，通过webbrowser插件

结构如下：webHandle:1900946
Handle:2031998|windowsname:|classname:Shell Embedding
Handle:2097774|windowsname:|classname:Shell DocObject View
Handle:3408466|windowsname:|classname:Internet Explorer_Server
Handle:1245802|windowsname:|classname:MacromediaFlashPlayerActiveX

网上有人实现了 不过是VB的代码  我调用api后老是错误。http://hi.baidu.com/%C4%BE%D2%D7%D8%A3/blog/item/9e12eb61cbc090c18db10dc8.html

AccessibleObjectFromWindow(phwnd, (uint)OBJID.CLIENT, ref guid, ref flash_main);获取的flash对象为空的、、

代码如下：
