I have to click a HTML button programatically which is on the 3rd page of the website. The button is without id. It has just name type and value. The HTML code of the button is given below

<FORM NAME='form1' METHOD='post' action='/dflogin.php'> <INPUT TYPE='hidden' NAME='txtId' value='E712050-15'><INPUT TYPE='hidden' NAME='txtassId' value='1'><INPUT TYPE='hidden' NAME='txtPsw' value='HH29'><INPUT TYPE='hidden' NAME='txtLog' value='0'><h6 align='right'><INPUT TYPE='SUBMIT' NAME='btnSub' value='Next' style='background-color:#009900; color:#fff;'></h6></FORM>

I am using the following code to click it

For Each webpageelement As HtmlElement In allelements

If webpageelement.GetAttribute("value") = "Next" Then


End If


But I can not able to click it. I am using the vb.net 2008 platform to click it. Can anyone tell me the solution to click it?
