问个关于webbrowse的问题

[puyinghua]

1、请问webbrowse的方法与属性？(搜了下，没找到资料，惭愧)

2、在dephi里，用这控件打开一个网页中，可以用以下方法得到一个表中的值

eg: 得到表对象 m_webBrowse.oleobject.document.all.tags("table")

那么在VC中呢？ 如果实现？

VC里面有webbrowse2控件，拖进去就能用了。

2 俺只知道应该是通过IHTMLDocument2接口来操作

VC里操作COM接口,要实现相同的目的,要烦多了

1，VC中有一个WebBrowser的控件，可以直接使用
2，通过IHTMLDocument2接口来操作
