I'm using Microsoft Visual Basic 2008 Express Edition. In the little program I'm creating, I added a WebBrowser and a button that will make the WebBrowser navigate to a designated website when clicked. So far, it's fine.

The following is a part of the source code of the website.

Javascript Code Constantly Changes And The Url Itself Will Change ?

Sep 13, 2010

I have built a web browser and my new window function is working great, it allows me to open popups that use normal https links without a hassle. But I am having some problems when the links contain java code (like the one below:

("javascript:var%20x=window.open('https://auth.det.nsw.edu.au/pls/orasso/orasso.wwsso_app_admin.fapp_process_login?p_app_id=F0CB644DAE48EDE00D83EFE378FD435E','My_Staff_Email','menu=no,toolbar=no,resizable=yes,scrollbars=yes,status=yes')"

The reason why this operation fails because the string that is being passed to the Navigate method is not an actual URL.It is apiece of Javascript code which needs Javascript engine to process it firstly. Apparently, Webbrowser.Navigate() does not have this functionality,so it fails. If you simply put the string in IE�s address bar and press enter, IE will also not able to open it. The reason why it does work if you access the HTML page in IE and click the hype link is because this will make IE to use Javascript engine to process the code.

Since the API(Webbrowser.Navigate) does not have the functionality to process Javascript code,build up my own code to process the string which you get by using the GetAttribute method. The code reads the string and finds the actual URL and passes it to the Navigate method.

The only problem is that the javascript code constantly changes (varies upon what link is opening) and the url itself will change depending on what the link is linking to! Below is the code that I use at the moment to get the full link .finding the actual URL in the javascript even with the javascript differing from link to link).

Dim myElement As HtmlElement = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Document.ActiveElement
Dim address As String = myElement.GetAttribute("href")
