开发面向WEBPAGE的ACTIVEX的几个问题，相信这是很多朋友都关注的问题

1、我是使用ATL ATTRIBUTE生成的控件框架，然后添加属性，编译注册后。
使用编程工具在DIALOG上添加此控件，所添加的属性都有在属性PROPERTIES框框里列出来，并且给初始值时候，能成功执行该属性对应的PUT函数。
但是问题就是在于把次控件放在WEBPAGE上的时候，使用<object ...><param name="..." value="...">...</object>的方法初始化那个属性值没有任何效果。

2、我们的控件也同样需要在IE里直接打开自定义的文件，文件关联是没有什么问题，但就是不知道应该使用什么规则，可以把IE地址栏所访问的自定义文件的URL告诉该控件？

3、控件在IE里访问INTERNET自定义文件的时候，是什么样的机制来获取此文件的？是有统一的做法，还是自己使用HTTPOPEN等方法来自己读取？如果是自己写代码读取的话，那么如何实现“象访问图片等IE使用的标准文件那样，不重复下载已经访问过的完全相同的自定义文件”？

不知道我的意思是否表达清楚，MSDN浩如烟海，好难找到相关资料，望高手指点！

学习中，关注中

把上面问题中没说清楚的几点补充下：
第3点里说到的自定义文件，就是指象FLASH控件作为IE的插件，安装后，IE就可以直接访问SWF文件。SWF就是FLASH控件的自定义文件。

这个问题怎么没多少人关注呢？这应该是很常用的东西吧？
