请教上传组件中的上传重命名问题!
我用的是 秋忆文件管理,
秋忆工作室在线文件管理器v4.4.rar (132 KB)
,上学生做作业上传文件后,文件常被人覆盖,能不能将 秋忆文件管理4.4版中,incupload.asp 文件修改成上传文件后,文件重命名为 原文件名+随机数,或者 原文件名+用户名+随机数?如果能够入文件能入库更好,谢谢!

可以参考
在开始接触ASP时,还没有真正体会到ASP的先天不良,直到1年前制作文件上传时,才让我吃了不少苦:|现特地整理出来,以供大家参考!
ASP文件上传最核心的代码实际很简单(代码如下)
 upload.asp文件
  <%
  Function GetFileName(ByVal strFile)
  If strFile <> "" Then
   GetFileName = mid(strFile,InStrRev(strFile, "\")+1)
  Else
   GetFileName = ""
  End If
  End  function
  strFileName = Request.Form("file1")
  Set objStream = Server.CreateObject("ADODB.Stream")
  objStream.Type = 1 ' adTypeBinary
  objStream.Open
  objStream.LoadFromFile strFileName
  objStream.SaveToFile Server.MapPath(GetFileName(strFileName)),2
  objStream.Close
  %>
upload.htm文件
  <form name="FORM" action="upload.asp" method="post">
  <input type="file" name="file1" style="width:400"  value="">
      <input type="submit" name="submit" value="文件上传">
  </form>
 
当然只有以上代码,虽然可以上传,但有很多的漏洞及不完善。因此网上有很多高人都对此进行了修改,用的最多的是稻香老农的ASP文件上传。此后又有一些高人在稻香老农的基础上进行了修改,增添了文件上传进度条,如宝玉。从中我们也可以感受到每个人对ASP做出的努力!
 
闲话少说,本人以目前较成熟的宝玉ASP上传为基础,进行修改,修改部分如下:
 1、支持多文件上传 (默认同时上传5个文件)
 2、格式限制
 3、上传总大小限制
 4、文件自动更名,防止重名 (自动以数字对文件名进行更名)
 5、上传文档信息至数据库,文件上传至站点
具体代码如下,内附解释!(如有问题,可与我联系)
 
 
  default.htm文件(默认只能上传JPG或GIF格式文件,可根据需要进行修改)
 
<html>
<head><title>带进度条</title></head>
