winhttp login form help

[NTBM]

I am trying to write an app to auto login to a website and then send commands to it.

The website is an internal to an ip controlled relay box (allows switching devices on/off via website)

i have done it with a gui that calls an ie session however this is ugle and would like to do it outside of ie.

here is the html of the login screen

expandcollapse popup

<title>IP Family</title>





<center>
<p align="left"><font color="#0033ff" size="5" face="Verdana, Arial, Helvetica, sans-serif"><em><strong><font size="4">Aviosys
      Inc.</font></strong></em></font></p>
<p align="left"><font size="+1" face="Georgia,Arial"><font color="#0000ff" size="+2" face="Verdana, Arial, Helvetica, sans-serif"><strong><font color="#000000" size="4" face="Arial"><b>Welcom to IP Family
      WebControl</b></font></strong></font></font></p>
<table border="0" width="392" bgColor="#dfdfdf" align="left">
<tbody><tr>
<td noWrap="">
<form method="post" name="login" action="/tgi/login.tgi">
<center>
<table cellSpacing="0" cellPadding="10" width="96%" align="center" NAME="myTable">
<tbody><tr vAlign="top" align="left">
<td colSpan="2"><font size="2" face="Arial, Helvetica, sans-serif">Please enter User name &amp;
Password. (maximum = 8)</font></td></tr>
<tr vAlign="top" align="left">
<td><font face="Verdana,Arial"><font size="-1">User
Name</font></font></td>
<td><input name="Username" maxLength="32" value="admin" size="32" type="text"></td></tr>
<tr vAlign="top" align="left">
<td height="46"><font face="Verdana,Arial"><font size="-1">Password</font></font></td>
<td height="46"><input name="Password" maxLength="32" value="" size="32" type="password"></td></tr>
<tr vAlign="top" align="left">
<td></td>
<td>
<p align="center"><input onclick="calcResponse(); return false;" name="Submitbtn" value="&#9;  OK&#9;  " type="Submit">
       <input onclick="document.login.Username.value='';document.login.Password.value=''" name="Cancel" value="   Cancel   " type="button">
</p></td></tr></tbody></table></center>
<input name="Challenge" value="k7n....." type="hidden"> <input name="Response" value="" type="hidden">
</form></td></tr>
<tr>
<td>
<p align="right"><a href="http://www.aviosys.com" target="_blank">www.aviosys.com</a></p></td></tr></tbody></table>
</center>

and here is the code i have so far

this results in a failed login screen, which i think is due to the shallange field but am unsure where to go from here?

Any advise would be great.

Cheers
