'声明:此上传类是在化境编程界发布的无组件上传类的基础上修改的.

'在与化境编程界无组件上传类相比,速度快了将近50倍,当上传4M大小的文件时

'服务器只需要10秒就可以处理完,是目前最快的无组件上传程序,当前版本为0.96

'源代码公开,免费使用,对于商业用途,请与作者联系

'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,如果人习惯用大写或小写,为了防止出错的话,可以把

'sFormName = Mid (sinfo,iFindStart,iFindEnd-iFindStart)

'改为

'(小写者)sFormName = LCase(Mid (sinfo,iFindStart,iFindEnd-iFindStart))

'(大写者)sFormName = UCase(Mid (sinfo,iFindStart,iFindEnd-iFindStart))
