如何编上传文件的ASP，来源程序吧给100分！！！

------------------不使用组件源代码------------------
主题：不用组件上载文件代码段
下面将介绍一系列可以不用组件，而使用纯粹的ASP代码来上传文件
呵呵，我想这将给很多拥有个人主页的网友带来极大的方便。
这个纯ASP代码由三个包含文件组成，代码中只使用了FileSystemObject
和Direction两个ASP固有对象。而不需要任何附加的组件，注意，为了保证
这段代码的出处，我没有对代码中的任何地方进行过修改。
希望能够对大家有所帮助：

1）首先你要去下载个组件，比如（LyfUpload），
2）然后要进行注册，在开始，运行窗中键入，
RegSvr32 c:\windows\system\LyfUpload.dll
3）做一个提交页面，
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title></title>
<meta name="GENERATOR" content="Microsoft FrontPage 3.0">
<style></style>
</head>

<body bgcolor="#C4E0FD">
<table border="0" width="100%" bgcolor="#FDDBC4">
<tr>
<td width="44%">
<p> </p>
<form method="POST" enctype="multipart/form-data" action="ti.asp">
选择文件：<input type="file" name="file1"><br>
选择文件：<input type="file" name="file2"><br>
<input type="submit" value="上载"
style="background-color: rgb(0,0,255); color: rgb(255,255,0)"> </p>
</form>
</td>
</tr>
</table>
</body>
</html>
4）做一个处理提交的ASP文件，(ti.asp)这里先假设是传输到C盘的C：\TEMP
处理提交的ASP文件
<%
Set obj = Server.CreateObject("LyfUpload.UploadFile")
ss=obj.SaveFile("file1", "C:\temp", true) '保存文件到服务器，这里先假设是C盘
aa=obj.filetype("file1")
cc=obj.FileSize
ss1=obj.SaveFile("file2", "C:\temp", true)
aa1=obj.filetype("file2")
cc1=obj.FileSize
if ss<> "" then
Response.Write "选择的文件已经上载到服务器！<br>"
Response.Write("文件名：" & ss)
Response.Write("<br>Content-Type：" & aa)
Response.Write("文件大小：" & cc)
end if
if ss1<> "" then
Response.Write "选择的文件已经上载到服务器！<br>"
Response.Write("文件名：" & ss1)
Response.Write("<br>Content-Type：" & aa1)
Response.Write("文件大小：" & cc1)
end if
%>
