我做的可上传下载控件，欢迎使用。

这是控件的源程序：
工程名：MY
控件名：TESTFTP

说明：有关主机名称，用户及口令等要改为你实际使用的。
生成OCX文件后再注册一下。
在网页里的调用：
<html>

<head>
<meta http-equiv="Content-Type"
content="text/html; charset=gb_2312-80">
<meta name="GENERATOR" content="Microsoft FrontPage Express 2.0">
<title>我的控件</title>
</head>

<body bgcolor="#FFFFFF">

<p><object id="1" name="1"
classid="clsid:282433B5-27DA-11D4-BE9B-0050BADA248E"
align="baseline" border="0" width="320" height="240"></object></p>
</body>
</html>
试用结果应该不错的。
