<HTML>
<HEAD><TITLE>File Send</TITLE></HEAD>
<BODY>
   <INPUT id=btn_send name="btn_send" type=button value="FILE SEND">
   <DIV id=div_message>Ready</DIV>

<SCRIPT LANGUAGE=JavaScript>

// files upload function
function btn_send.onclick()
{
   // create ADO-stream Object
   var ado_stream = new ActiveXObject("ADODB.Stream");

   // create XML document with default header and primary node
   var xml_dom = new ActiveXObject("MSXML2.DOMDocument");
   xml_dom.loadXML('<?xml version="1.0" ?> <root/>');
   // specify namespaces datatypes
   xml_dom.documentElement.setAttribute("xmlns:dt", "urn:schemas-microsoft-com:datatypes");

   // create a new node and set binary content
   var l_node1 = xml_dom.createElement("file1");
   l_node1.dataType = "bin.base64";
   // open stream object and read source file
   ado_stream.Type = 1;  // 1=adTypeBinary 
   ado_stream.Open(); 
   ado_stream.LoadFromFile("c:\\sold.gif");
   // store file content into XML node
   l_node1.nodeTypedValue = ado_stream.Read(-1); // -1=adReadAll
   ado_stream.Close();
   xml_dom.documentElement.appendChild(l_node1);

   // we can create more XML nodes for multiple file upload

   // send XML documento to Web server
