I am doing some tests before the purchase to know if this library will be usual I like very much

I could not do it simply is to get a control that I could already get in a conventional webcontrol

Dim link As HtmlElement = nav.Document.Window.Frames (0) .Frames (0) .Document.Forms (0) .Document.GetElementsByTagName ("a") Item

Iframes are in the same domain

it is possible?

Thank you

Hi,

You will need to modify your code to use WebView.EvalScript in order to use EO.WebBrowser to achieve the same thing. See here for more details:

Please let us know if you still have any questions.

Thanks!

WebView1.EvalScript("document.getElementById('Button1').click();");

Ok I already checked this code does not work when the control or function is inside an iframe
Even releasing the options

options.EnableXSSAuditor = false;
options.EnableWebSecurity = false;
options.AllowJavaScript = true;
options.AllowJavaScriptAccessClipboard = true;
options.AllowPlugins = true;
options.AllowJavaScriptDOMPaste = true;
options.AllowJavaScriptOpenWindow = true;
EO.WebBrowser.Runtime.RemoteDebugPort = 1234;
EO.WebBrowser.Runtime.SetDefaultBrowserOptions (options);
webrowser1.SetOptions (options); options.EnableXSSAuditor = false;


Thanks for your response

Hi,

EnableWebSecurity is the correct setting to turn cross site scripting policy off. However you need to set it before the WebView is created. If you look at the TabbedBrowser sample application source code, you can add code like this:

Code: C#
EO.WebEngine.Engine.Default.Options.SetDefaultBrowserOptions(your_options);


Inside App.xaml.cs/App.xaml.vb before the MainWindow is created.

Thanks!
