How to pass the IE windows handle out of the WebBrowser? -- dotnet windows forms controls

Hi Sheng,

Thanks for your reply.

I tried the NewWindow2 with csExWB but it does not work.

Here is the index.html I accessed.

<script language="JScript">
function rewriteServiceAgreement(){
page="RegenerateServiceAgreement";

var windowName = "SA_";

var w = null;

var blankname= "blank.html";
var retry=0;
while (w == null && retry<100) {
if(retry > 0) {
alert('Regenerating service agreement.');
}
alert(retry);
w = open(blankname, windowName,
'width=890,height=600,screenX=0,screenY=0,scrollbars=yes,menubar=yes');
retry++;
alert(retry);
}

if(w == null) {
alert('IE BUG: the dwindow is still null.');
}else if(w.document == null){
alert('IE BUG: the document is null.');
}

var s = "<body><html>test</html></body>";

w.document.close();
w.document.open();
w.document.write(s);
w.document.close();
w.focus();
}
</script>
<body onclick="rewriteServiceAgreement();">
Click this page and window.open() is called.
</body>

Here is my handle code for event NewWindow2.

string url;
private void cEXWB1_NewWindow2(object sender,
csExWB.NewWindow2EventArgs e)
{
Form1 form = new Form1();
form.navigate(url); // We get the blank page.
e.browser = form.Browser; // form.Browser is a default .NET WebBrowser
control.
form.Show();
}

private void cEXWB1_NewWindow3(object sender,
csExWB.NewWindow3EventArgs e)
{
url = e.url;
}

But I never see the second alert(retry). It looks like the javascript is
hung up on the â€œopenâ€ statement once the event handle code has been executed.
And the javascript works if we comment e.browser = form.Browser.

Do you know what reason is and how to resolve it?

Any help is appreciated.

You are pass a reference of a .Net wrapper object, while the event expect an
reference to an WebBrowser ActiveX object.

Hi Sheng,

Thanks for your reply. I changed the Browser type from default WebBrowser to
AxSHDocVw.AxWebBrowser. But the javascript is still hung up.

string url;
private void cEXWB1_NewWindow2(object sender,
csExWB.NewWindow2EventArgs e)
{
Form1 form = new Form1();
form.navigate(url);

e.browser = form.Browser; // Browser is AxSHDocVw.AxWebBrowser type.

form.Show();
}

Here is the class Form1.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

public void navigate(string url)
{
this.axWebBrowser1.Navigate(url);
}

public AxSHDocVw.AxWebBrowser Browser
{
get { return axWebBrowser1; }
set { axWebBrowser1 = value; }
}
}

Do you have any suggestion? Any help is appreciated.

If you can get the ActiveX's IWebBrowser2 interface, return its Application
property to NewWindow2.
