knowing when a file download is complete

[IGC]

I have a requirement to record in a database when a file is finished
downloading to the end-user. Currently when a user clicks a download icon
for a file it directs to an ASP page that records the "hit" into a database,
then I use a response.redirect "filename.exe" to point the user to the
download. What I'm missing is knowing when the download is complete so I
can update the database to show the file successfully completed its
download. Is there a way to do this with ASP? A way to do this with an
aftermarket component?

Sorry, ASP can't detect this. You could try response.isClientConnected but
that only refers to the web page... e.g. if they close the browser window
and continue the download, you will get a false negative.

Other than ASP, what can? There must be something out there that does.
When I download patches from MS and I get disconnected mid-stream, it knows
that I did and will continue downloading. Then it does an install after the
download completes. Then the page redirects to a install complete page.
Although I don't need to do an actual install, I do NEED to know when the
download successfully completes.

That's because Windows Update uses an activeX control that is installed on
your computer the first time you go to the site, assuming you accept the
installation.

What is that ActiveX componenet called? Where do I get that ActiveX
component?

It's called Windows Update, and Microsoft made it for the Windows Update
site. It's not something you can download and use for your own site or
anything like that.

Use the Response.BinaryWrite method to stream the file out from the ASP
page?
You may get an error generated if the client disconnects prematurely (should
see a doctor perhaps) eg. before the entire file has been streamed out?

I found it!!!

Informentum has a product called ActiveFile which allows me to download a
file from ASP and know wether or not it worked.

Simply:

Dim result, File1
Set File1 = Server.CreateObject("ActiveFile.File")
File1.Name = "D:\MyDocuments\program.exe"
Response.Clear
Response.AddHeader "Content-Disposition", "attachment; filename=" &
File1.FileName
result = File1.Download
Set File1 = Nothing

Now "result" is true or false depending if the entire file is downloaded.
Very cool indeed!!

Thanks for all your help!

No, but I'm sure I read recently that you could download something similar.

I'm sure that BITS could be incorporated into something.
