'聲明:此上傳類是在化境程式設計界釋出的無元件上傳類的基礎上修改的.

'在與化境程式設計界無元件上傳類相比,速度快了将近50倍,當上傳4M大小的檔案時

'伺服器隻需要10秒就可以處理完,是目前最快的無元件上傳程式,目前版本為0.96

'源代碼公開,免費使用,對于商業用途,請與作者聯系

'檔案屬性：例如上傳檔案為c:\myfile\doc.txt

'FileName 檔案名 字元串 "doc.txt"

'FileSize 檔案大小 數值 1210

'FileType 檔案類型 字元串 "text/plain"

'FileExt 檔案擴充名 字元串 "txt"

'FilePath 檔案原路徑 字元串 "c:\myfile"

'使用時注意事項:

'由于Scripting.Dictionary區分大小寫,是以在網頁及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))

'(大寫者)sFormName = UCase(Mid (sinfo,iFindStart,iFindEnd-iFindStart))
