Multiple webbrowser control parent/child pop up

**jsublime** · Jun 15th, 2012, 09:41 AM

I know it's confusing to understand what I'm trying to do without source code so I rebuilt it in a simple way.

Webbrowser1 loads html1.htm at startup. I have a handler which cancels the popup and redirects webbrowser2 to the pop up url (I simplified this a bit in this demo by hardcoding html2).

Code:

   Private Sub WebBrowser1_NewWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles WebBrowser1.NewWindow

        ' This will be triggered only when link tries to open in new window.
        ' That means active element in web document will always be a Link.
Dim myElement As HtmlElement = WebBrowser1.Document.ActiveElement
        Dim target As String = myElement.GetAttribute("Url")
       
'target *should* capture the destination url which is yahoo.com in this case. in this example i am redirecting the page to a hardcoded page

        WebBrowser2.Navigate(HTML2.html)

        'cancel opening IE window
        e.Cancel = True


    End Sub

HTML 1:

HTML Code:

<SCRIPT type = "text/Jscript">
     function openWin()
     {
          var win;
          win = window.open("http://www.yahoo.com");
     }
</SCRIPT>
</HEAD>
<BODY>

<button onClick="openWin()">Open New Window</button>

</BODY>
</HTML>

HTML 2:

HTML Code:

<SCRIPT type = "text/Jscript">
     function openWin()
     {
          var win;
          win = window.opener.navigate("http://www.google.com");
     }
</SCRIPT>
</HEAD>
<BODY>

<button onClick="openWin()">Open New Window</button>

</BODY>
</HTML>

After I click the link in wb1, wb2 has a function called window.opener which tells the parent window (wb1) to navigate to google.com. I get the following error:

'window.opener' is null or not an object.

Basically webbrowser2 doesn't have any connection to it's parent window and I can't seem to set it programtically.
