NHtmlUnit cannot submit button

Question

I'm discovering about NHtmlUnit to build an application web. But when I try it with auto login to yahoo mail. But after I run code. I refresh the login page of Yahoo so nothing changed. Not logged.

Code:

        NHtmlUnit.WebClient driver = new NHtmlUnit.WebClient();

        driver.Options.JavaScriptEnabled = true;
        driver.Options.ThrowExceptionOnScriptError = false;
        driver.Options.ActiveXNative = true;
        driver.Options.CssEnabled = true;

        HtmlPage page = driver.GetHtmlPage("https://login.yahoo.com/config/login?");

        HtmlForm form = page.GetFormByName("login_form");
        HtmlTextInput user = (HtmlTextInput)form.GetInputByName("login");
        HtmlPasswordInput pass = (HtmlPasswordInput)form.GetInputByName("passwd");

        user.SetValueAttribute("my account");
        pass.SetValueAttribute("my pass");

        HtmlSubmitInput submitButton = (HtmlSubmitInput)page.GetElementByName(".save");

        HtmlPage nextpage = (HtmlPage)submitButton.Click();

Please help me why. I write it on .NET MVC 4 C#. Thank you very much.

HtmlButton submitButton = (HtmlButton)page.GetElementByName(".save");

The code is completely fine, and should works.

Probably the reason you think it is not, is that you check it by a wrong method! One essential elements which makes a site (i.e. login.yahoo.com) see you as logged in user, is the cookies it provide to your browser/webdriver when you use login forms, so if you use the login procedure by an instance of NHtmlUnit.Webclient (i.e. driver) then you are only logged in inside the driver web client, not inside any other browser or client, even on the same machine.

I tried to add this as a comment, but I don't have enough reputations.
