在HtmlView中如何改变链接.
如在网页中有二个链接
<a href="aa.htm">aa</a>
<a href="bb.htm">bb</a>
现在我想改变<a href="aa.htm">aa</a>的链接.改成<a href="cc.htm">cc</a>.
请问有什么方法呢?千万别告诉我用查找字符串替换字符串哦.

你能给我一个源码吗?我用你的代码编译了一下,有很多错啊.
我的E-Mail是guzh@21cn.com 谢谢了.

f:\VC\ChangeHref\ChangeHref\MainFrm.cpp(109): error C2065: “IDispatchPtr” : 未声明的标识符
f:\VC\ChangeHref\ChangeHref\MainFrm.cpp(109): error C2065: “GetHtmlDocument” : 未声明的标识符
.....
等等.

you can use CHtmlView::GetHtmlDocument to get IDispatch*,
IDispatchPtr spDisp=GetHtmlDocument();

void CChangeurlView::OnEditChangeurl()

// please note that you have to release those interface pointer
IDispatch* spDisp;

spDisp->QueryInterface(IID_IHTMLDocument2,(void**)&spDoc);
