'聲明:此上傳類是在化境編程界發布的無組件上傳類的基礎上修改的.
'在與化境編程界無組件上傳類相比,速度快了將近50倍,當上傳4M大小的文件時
'服務器只需要10秒就可以處理完,是目前最快的無組件上傳程序,當前版本為0.96
'源代碼公開,免費使用,對于商業用途,請與作者聯系
'文件屬性：例如上傳文件為c:\myfile\doc.txt
'FileName????文件名???????字符串????"doc.txt"
'FileSize????文件大小?????數值???????1210
'FileType????文件類型?????字符串????"text/plain"
'FileExt?????文件擴展名???字符串????"txt"
'FilePath????文件原路徑???字符串????"c:\myfile"
'使用時注意事項:
'由于Scripting.Dictionary區分大小寫,所以在網頁及ASP頁的項目名都要相同的大小
'寫,如果人習慣用大寫或小寫,為了防止出錯的話,可以把
'sFormName?=?Mid?(sinfo,iFindStart,iFindEnd-iFindStart)
'改為
'(小寫者)sFormName?=?LCase(Mid?(sinfo,iFindStart,iFindEnd-iFindStart))
