}
</script>
</head>
<body>
<input name="textfield3" type="file" class="input" id="textfield3" size="30" value="" onkeydown="upLoadKey(event);" onpaste="return false;" onmousedown="document.oncontextmenu = function() { return false;}" onmouseout="document.oncontextmenu = function() { return true;}" style = "ime-mode:disabled" />
