vbsUpload.asp

This is the file which contains the whole logic of the File Upload. The Request.Binary read method is used to read the raw data sent by the client as part of a POST request. ASP provides a method to apply URL encoding rules, but no publicly exposed way to decode. The URLDecode method does that URLDecoding. Then the raw data is parsed and the File elements and Form Elements are separately kept in two collection objects.

Process_File.asp

This is a simple asp file used to Upload the multipart/form-data. Once the data is available this file will save the file on the hard disk. The file is as follows:

<%@ Language="VBScript" %>
<!-- #include file="vbsUpload.asp" -->
<form method=post
      enctype="multipart/form-data"
      action=<%=request.servervariables("script_name")%>>
Your File:<BR><input type=file name=YourFile><BR><BR>
<input type=submit name=submit value="Upload">
</form>
<%
Dim objUpload, lngLoop

If Request.TotalBytes > 0 Then
	Set objUpload = New vbsUpload

  For lngLoop = 0 to objUpload.Files.Count - 1
    'If accessing this page annonymously,
    'the internet guest account must have
    'write permission to the path below.
    objUpload.Files.Item(lngLoop).Save "c:\Newupload\"

	Response.Write "File Uploaded"
	Next

End if
%>

Process_DB.asp

This is another simple file to get multipart/form-data but this will save the data in the Database

conn.asp

This is for using SQLServer to store the files. I have provided the Script to create the Table. So you can create the same table format and use it. Don't forget to fill in the correct Connection String.

Download.asp

This file is used to retreive the binay data from the Database and to display on the Web.
