    Try this,

    HtmlElement head = _windowManager.ActiveBrowser.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = _windowManager.ActiveBrowser.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
element.text = "window.onload = function() { document.forms[0].submit(); }";
head.AppendChild(scriptEl);
strAdditionalHeader = "";
_windowManager.ActiveBrowser.Document.InvokeScript("webBrowserControl");

    Try using document.getElementById("myForm") instead of document.myForm.

    <script>
var auto_refresh = setInterval(function() { submitform(); }, 10000);

function submitform()
{
  alert('test');
  document.getElementById("myForm").submit();
}
</script>

    A simple solution for a delayed auto submit:

    <body onload="setTimeout(function() { document.frm1.submit() }, 5000)">
   <form action="https://www.google.com" name="frm1">
      <input type="hidden" name="q" value="Hello world" />
   </form>
</body>

    You need to specify a frame, a target otherwise your script will vanish on first submit!

    Change document.myForm with document.forms["myForm"]:

    <form name="myForm" id="myForm" target="_myFrame" action="test.php" method="POST">
    <p>
        <input name="test" value="test" />
    </p>
    <p>
        <input type="submit" value="Submit" />
    </p>
</form>

<script type="text/javascript">
    window.onload=function(){
        var auto = setTimeout(function(){ autoRefresh(); }, 100);

        function submitform(){
          alert('test');
          document.forms["myForm"].submit();
        }

        function autoRefresh(){
           clearTimeout(auto);
           auto = setTimeout(function(){ submitform(); autoRefresh(); }, 10000);
        }
    }
</script>

    This solution worked for me:

    <body onload="setTimeout(function() { document.myform.submit() }, 5000)">
   <form action=TripRecorder name="myform">
      <textarea id="result1"  name="res1" value="str1" cols="20" rows="1" ></textarea> <br> <br/>
      <textarea id="result2" name="res2" value="str2" cols="20" rows="1" ></textarea>
   </form>
</body>
