the Button dosent have a name so im stomped in how to get this to work? the button doens have a ID or name so i cant use the GetElementById or GetElementsByName

webBrowser1.Document.All.GetElementsByName("j_username")[0].SetAttribute("Value", "************");
        webBrowser1.Document.All.GetElementsByName("j_password")[0].SetAttribute("Value", "******");
        webBrowser1.Document.All["Login"].InvokeMember("click");

;

anyone have a suggestion?

Answer 1

You could use GetElementsByTagName

    HtmlElementCollection elems = webBrowser1.Document.GetElementsByTagName("INPUT");
    foreach (HtmlElement elem in elems)
    {
        String valueStr = elem.GetAttribute("value");
        if (valueStr != null && valueStr.Equals("Login"))
        {
            elem.InvokeMember("click");                
        }
    }

I know that there are shorter ways to do this using LINQ however I think this is the clearest example of what is going on.
