<head runat="server">
<script type="text/javascript">function SetCwinHeight(obj)
{
  var cwin=obj;
  if (document.getElementById)
  {
    if (cwin && !window.opera)
    {
      if (cwin.contentDocument && cwin.contentDocument.body.offsetHeight)
        cwin.height = cwin.contentDocument.body.offsetHeight; 
      else if(cwin.Document && cwin.Document.body.scrollHeight)
        cwin.height = cwin.Document.body.scrollHeight;
    }
  }
}
</script></head>
<body onload="">
    <form id="form1" runat="server">
    <div>
<iframe width="778" align="center" height="200" id="cwin" name="cwin" src="http://www.sina.com"  onload="Javascript:SetCwinHeight(this)" frameborder="0" scrolling="no"></iframe>
