WPF Web Browser - How to set values for Input Tags?

Question

I am hoping that this is simple, but it's giving me some trouble.

I have a method that will navigate the web browser control to a login page:

private void goNavigateButton_Click(object sender, RoutedEventArgs e)
        {
            // Get URI to navigate to
            Uri uri = new Uri(this.addressTextBox.Text, UriKind.RelativeOrAbsolute);

            // Only absolute URIs can be navigated to
            if (!uri.IsAbsoluteUri)
            {
                MessageBox.Show("The Address URI must be absolute eg 'http://www.microsoft.com'");
                return;
            }

            // Navigate to the desired URL by calling the .Navigate method
            this.myWebBrowser.Navigate(uri);

        }

Once the WebBrowser control has the page, I want to get to the username input tag and put a value into the tag. 

Pseudo Code Example : Document.getTagByName("username3").value = "MyName";

Thanks!

It's not too bad, you need to use mshtml for this.

So first add a reference to Microsoft.mshtml to your project and then something like this:

using mshtml;

HTMLDocument dom = (HTMLDocument)Browser.Document;
object ie = dom.getElementById(username3);
if (ie!=null)
  {
  if (ie is IHTMLInputElement)
    {
    ((IHTMLInputElement)ie).value = "MyName";
    }
  }

(untested extract but I think it should work)
