Hi Nicolas,

//add a reference to the MSHTML Object Library

[...]

public Form1()
{
InitializeComponent();

// Wait until the document has finished loading
axWebBrowser1.DocumentComplete +=
new AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEventHandler(
axWebBrowser1_DocumentComplete);
}

private void button1_Click(object sender, System.EventArgs e)
{
//C# cannot deal with optional params
object miss = Type.Missing;
//goto google.com
axWebBrowser1.Navigate(
"http://www.google.com", ref miss, ref miss, ref miss, ref miss);
}

//is called when the browser has finished loading the page
private void axWebBrowser1_DocumentComplete(
object sender, AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
{
//get a reference to the HTML-document
mshtml.HTMLDocumentClass doc =
(mshtml.HTMLDocumentClass) axWebBrowser1.Document;

//foreach link in the HTML-document
foreach (mshtml.HTMLAnchorElementClass link in doc.links)
{
if (link.href == "http://www.google.de/grphp?hl=de&tab=wg")
{
//perform the click on the Google-Groups-Link
link.click();
}
}
}

Hi Nico,

then try it with

foreach (mshtml.IHTMLElement he in doc.links)
{
HTMLAnchorElementClass hae = he as HTMLAnchorElementClass;
...
}

nicolas · Jul 30, 2004

{

string URL = textBox1.Text;

//C# cannot deal with optional params

object miss = Type.Missing;

//goto google.com

axWebBrowser1.Navigate(

URL, ref miss, ref miss, ref miss, ref miss);

}

private void axWebBrowser1_Enter(object sender, System.EventArgs e)

{

}

private void textBox1_TextChanged(object sender, System.EventArgs e)

{

}

private void button2_Click(object sender, System.EventArgs e)

{

//get a reference to the HTML-document

mshtml.HTMLDocumentClass doc =

(mshtml.HTMLDocumentClass) axWebBrowser1.Document;

//foreach link in the HTML-document

foreach (mshtml.IHTMLElement he in doc.links)

{

HTMLAnchorElementClass hae = he as HTMLAnchorElementClass;

textBox2.Text=hae.href;

}

}

private void textBox2_TextChanged(object sender, System.EventArgs e)

Hi nicolas,

IE-Automation in C#...

.... it's all about trial&error... ;-)

This one is working for me:

public Form1()
{
InitializeComponent();
axWebBrowser1.DocumentComplete +=
new AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEventHandler(
axWebBrowser1_DocumentComplete);
}

private void button1_Click(object sender, System.EventArgs e)
{
//C# cannot deal with optional params
object miss = Type.Missing;
//goto yahoo.com
axWebBrowser1.Navigate(
"http://www.yahoo.com", ref miss, ref miss, ref miss, ref miss);
}

private void axWebBrowser1_DocumentComplete(
object sender,
AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
{
//get a reference to the HTML-document
mshtml.HTMLDocumentClass doc =
(mshtml.HTMLDocumentClass) axWebBrowser1.Document;

//foreach link in the HTML-document
foreach (mshtml.IHTMLElement link in doc.links)
{
MessageBox.Show(
link.getAttribute("href", 0).ToString());
}
}

Cheers

Arne Janning

(Let's try if we can call scripts in a webbrowser-control from C# as
well ;-)
