Upload Files to Active Server Pages

This tip works with ASP/IIS 4.0 and up. Many companies sell ActiveX objects for uploading files to Active Server Pages. However, you can easily write a bit of VBScript to handle the uploads yourself. The Request object has all the uploaded data:
	HTML for the upload form
<form action="upload.asp" method="post" _
<input type=file name="file1" size=20><br>
<input type=file name="file2" size=20><br>
<input type=submit>

	ASP Code for the upload
	' This code is needed to "initialize" the 
	' retrieved data
	Dim q
	q = Chr(34)
	' All data
	Dim aAllDataB, aAllData, x, aHdr
	aAllDataB = Request.BinaryRead(Request.TotalBytes)
	' It comes in as unicode, so convert it to ascii
	For x = 1 To LenB(aAllDataB)
		aAllData = aAllData & Chr(AscB(MidB( _
			aAllDataB, x, 1)))
	' The "header" is a unique string generated by the 
	' system to indicate the beginning
	' and end of file data
	aHdr = Left(aAllData, Instr(aAllData,vbCrLf)+1)

	' Here's where your code goes.
	' In this example, "file1" and "file2" are the 
	' field names specified within the form of the 
	' upload submission page.
	Response.Write "file1: Filename = " & _
		GetFilename("file1") & "<br>"
	Response.Write GetFileData("file1") _
& "<br><br>"

	Response.Write "file2: Filename = " & _
		GetFilename("file2") & "<br>"
	Response.Write GetFileData("file2") _
& "<br><br>"

	' Writing out the file data like this only looks 
	' OK when the uploaded file is some kind of text
