如何利用HTMl调用Dll文件里的函数！！！！！！！！
亲们，谁知道如何用HTML调用dll文件，听说是先注册到注册表，然后再html里写<object .....这个标签调用它的calassid,我不太明白calssid是什么东西，怎么来的，
具体怎么用请可谓大侠详细解说一下，小弟在线等待，拜托了......... HTML 注册表 调用dll文件
[解决办法]
<object id="myAxControlTest" width="180" height="20" codebase="MyAtx.cab" classid="clsid:8173BE03-E29B-49CB-A4B4-52778F6E37E5">
</object>
//与该html同路径放有 activex插件
//获取activex插件的值
//alert(document.getElementById("myAxControlTest").IsHaveFile);//IsHaveFile为插件公开的方法名
[解决办法]
classid对应插件的Guid

return GetFiles(new DirectoryInfo(@"D:\zxy"), "*.*").ToString();
}
