无惧 无组件上传完整代码

很好用的一个基本的无组件上传的类

首先是class文件  upclass.inc

<%
"----------------------------------------------------------------------
"******************* 无组件上传类 ********************************
"类属性包括
"文件属性：例如上传文件为c:\myfile\doc.txt
"FileName 文件名 字符串 "doc.txt"
"FileSize 文件大小 数值 1210
"FileType 文件类型 字符串 "text/plain"
"FileExt 文件扩展名 字符串 ".txt"
"FilePath 文件原路径 字符串 "c:\myfile"
"使用时注意事项:
"由于Scripting.Dictionary区分大小写,所以在网页及ASP页的项目名都要相同的大小写
