' Disclaimer: This upload class was modified on the basis of transformation-free upload classes published by the programming community.
' It's nearly 50 times times faster than uploading classes without components in the transformation programming world, when uploading files of 4M size
The server only needs 10 seconds to process, is currently the fastest component-free upload program, the current version of 0.96
' Source code open, free to use, for business purposes, please contact the author
' File attributes: For example, uploading files for C:myfiledoc.txt
' filename filename string ' doc.txt '
' FileSize File size value 1210
' FileType file type string ' Text/plain '
' Fileext file name extension string ' txt '
' FilePath file original path string ' C:myfile '

' Because Scripting.Dictionary is case-sensitive, the project names on the page and ASP pages are the same size

' (lowercase) sformname = LCase (Mid (Sinfo,ifindstart,ifindend-ifindstart))
