    elm.SetAttribute("type", "text/javascript");
    elm.InnerText = System.IO.File.ReadAllText(Environment.CurrentDirectory + @"\helperscripts.js");
    ((HtmlElement)head[0]).AppendChild(elm);
}

, so all methods of helperscript.js can be invoked using

webBrowser1.Document.InvokeScript("methodname");
