astfilename = "c:\myflashfile.swf"
<!--#include file="swfparser.asp" -->

After I've done this, I will have access to the following variables:

This code can also be expanded to grab some addiitional information such as frame rate.

Download the code

Update:
Some time after I created this article I came across another site who created a VBScript class to accomplish the same task. Check out this user tip on 4guysfromrolla.com.

Just a quick note that this only works on Flash files up to version 5. In Flash 6, they implemented compression using the zlib format. If somebody comes up with a vbscript or javascript approach to decompress it, it should be easy enough to grab these parameters then.

one line of code includes

if ucase(strTag) = "FWS" then isFlash=true

Well, a compressed flash file is "CWS", and you need gzip compression to uncompress everything from the 8th byte and on. Can you help us out with that?

I never got around to developing an ASP gzip decompressor. Creating one isn't something I'm interested in as ASP is certainly not as popular as it once was. Good luck with your project.
