请问嘉缘老师，我下载了你的求职程序2.15版，但是发现了一个问题，就是当在后台发布新闻，插入图片后，当想删除时，虽然删除了数据库中的文件，但是上传在服务器上的图片却仍然在，删不掉，请问这是怎么回事？请问怎样才能删除保留在服务器上的残余图片呢？否则，图片越来越多，就变成了垃圾了。万分感谢！
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
另外，我曾下载过你的一个程序，也是关于图片上传的，下面的代码是表单提交后，即图片提交后到表单处理页面的：
from=upload.form("from")
if upload.form("checkbox3")="1" then
selectpic=1
else
selectpic=0
end if
iCount=0
for each formName in upload.file ''列出所有上传了的文件
set file=upload.file(formName) ''生成一个文件对象
if file.FileSize>0 then ''如果 FileSize > 0 说明有文件数据
if file.filesize>150000 then
HtmEnd "您上传的文件大于规定大小(50K),请改变文件大小后再进行上传。"
else
if trim(right(file.FileName,3))<>"jpg" and trim(right(file.FileName,3))<>"gif" then
HtmEnd "您上传的文件GIF或JPG图象文件，请将你上传的文件转换此格式后再进行上传。"
else
file.SaveAs Server.mappath(formPath&file.FileName) ''保存文件
picurl=file.FileName
iCount=iCount+1
end if
end if
end if
set file=nothing
next
set rs=server.CreateObject("ADODB.RecordSet")
rs.open "select * from news",conn,3,2
rs.addnew
rs("title")=title
rs("content")=replace(content," "," ")
rs("nfrom")=from
rs("selectpic")=selectpic
rs("typeid")=typeid
rs("typename")=typename1
rs("tjnews")=tjnews
rs("picurl")=picurl
rs.update
rs.close
set rs=nothing
conn.close
set upload=nothing ''删除此对象
Htmend iCount&" 个文件上传结束!"
sub HtmEnd(Msg)
set upload=nothing
response.write "<br>"&Msg&" [<a href=""javascript:history.back();"">返回</a>]</body></html>"
response.end
end sub
%>
</body>
</html>
另外，还有一个插入文件：upload_5xsoft.inc

这是前页的表单代码： <TD width="15%" align="right" height="30"><font color="#FFFFFF">上传图片：</font></TD>
<TD width="85%"><INPUT NAME="file" TYPE="file" SIZE=60 maxlength=100 class="smallinput"></TD>
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
问题是这样的，我从没有自已做过关于图片上传的程序，只知道一种是用服务器上传组件来完成，另一种是不用组件直接用asp代码上传保存到数据库中，请问上面的代码表示的是哪一种呢，能否指导一下，这样我就可以在网上搜索相关资料自已学习了。再次感谢。上面的代码同样一样，就是删除了新闻后，数据库中虽然没有了，但图片仍然还保留在服务器上。不知道用什么办法或语句可以删除掉。
再再次致谢，希望有幸得到回复！
