化境http上传
① 化境HTTP上传程序 Version 2.0上传文件问题
服务器是自己的吗?在IIS的配置文件里还有个上传文件大小设置,把那里也改了.
运行inetmgr
停止IIS admin service服务
用记事本打开Windows\system32\inesrv目录下的metabase.xml
将ASPMaxRequestEntityAllowed的值修改为所需值
然后重启IIS admin service服务
AspMaxRequestEntityAllowed="20480000"
② asp上传单个图片的最简单代码是什么
需要三个文件：
第一个（upload.asp）
<% Response.Buffer=True %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>图片上传</title>
</head>
<body background="images/bg.gif" topmargin="30" style=""><div align="center">
<center>
<table border="1" cellspacing="1" style="border-collapse: collapse" bordercolor="#C0C0C0" width="420" id="AutoNumber69" bgcolor="#F5F5F5">
<tr>
<td width="100%" bgcolor="#F5F5F5" bordercolor="#F5F5F5"><form name="form1" method="post" action="uploadsave.asp" enctype="multipart/form-data">

④ 我做好了文件，可怎么也上传不了谁能回答我，要快！！
总的来说有三种结论：1.你要保存的文件名已存在,而未设置savetofile方法的覆盖属性 2.路径没有用server.MapPath()映射,这种情况下: 如果路径为绝对路径,则发生上面的问题:写入文件失败. 如果路径为相对路径,3.目录权限问题。
我也曾遇到此问题，在网上等了NNNN久，竟无人能回答，解铃尚需系铃人，问题我已解决，办法奉献于众，供大家参考，使用化境的上传组件，若网站在服务器的根目录，通常是不会遇到此类问题的，遇到此问题往往是网站是以二级目录方式存放在服务器IIS内，化境的上传路径默认是根目录，因此必须修改化境的上传保存文件的路径，也就是提示出错的ASP网页(ManageAddSave.asp→我的出错网页名)，而不是提示“dr.SaveToFile FullPath,2”写入出错所在的文件(UpFile.inc.inc→我的化境无组件上传文件名)，将提示出错的网页打开，修改上传文件保存路径“ formPath="/UploadFile/NewsFile"'得到上传目录”，如：你的网站存放的二级目录为‘web2’，路径则改为：“ formPath="/web2/UploadFile/NewsFile"'得到上传目录”，至此，问题解决上传成功!这是我解决此难的心得，奉献大家以供参考，如能解决你遇到的问题，请顶一下!
