'*******************    无组件上传类  ********************************
'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:\
'FileName    文件名      字符串    ""
'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))
