How does one automatically call a button or <A> tag click event similar to the doc in the webbrowser control?

This. webbrowser1.document. Click + = new htmlelementeventhandler (document_click );

Void document_click (Object sender, htmlelementeventargs E)
{

If (readonly)
{
If (webbrowser1.document. activeelement. domelement is htmlanchorelement)
{
Htmlanchorelement em = (htmlanchorelement) webbrowser1.document. activeelement. domelement;
String href = em. href;
.......
}
}
}

Or:

Htmldocument hdoc = webbrowser. Document;
Htmlelement he object = hdoc. getelementbyid ("Object ID ");
He object. invokemember ("click ");

You can also use hdoc. getelementsbytagname ("tagname") to retrieve the object.

As a browser, how to obtain the specific link on the page and click it.

Actually relatively simple
Mshtml. ihtmldocument2 Doc = (mshtml. ihtmldocument2) This. axweb_browser.document;
Mshtml. ihtmlelementcollection myliks = Doc. links;
String tmp_ads_url = "xxxxxxx ";
Foreach (htmlanchorelementclass El in myliks)
{
If (El. href. tostring (). tolower () = tmp_ads_url)
{
El. Click ();
Break;
}
}

Okay. The problem that the current link does not open in a new window is also solved. The method is also very simple. You just need to find the specified link in my implementationCodeAdd
El.tar get = "_ Self ";
You don't have to say where to add it.
