Hmmm, I never knew that websites can change all the links on the page depending
on who visits them, even if the site itself may be hosted somewhere else and
the content is on this Akamai url. My guess would be that when I request the
URL, their main server decides which is closest and routes the connection there
for the download to start. If I do indeed get a different url than everyone
else who grabs one from a file off the same site, that particular site may not
be a good example. The idea is that you could probably change the base url
easily, if another 3-hour or other duration show were found that was in
separate files with a predictable pattern like this. I just picked this example
as it'd be more basic than card games, and it was the problem I wanted to deal
with without slowing my machine down with Itunes since working with the broken
podcast feed would be more difficult.

If you adopt such an audio grabber as a multi-user project, you should check
first to see whether that Akamai leading URL has location information embedded
in it. Akamai is a service for high-speed delivery of content to widely
scattered users by means of widely distributed servers, and I wouldn't be
surprised if the URL which Brent gets would be different from the URL for
Michigan or South Africa.

Hi Brent: Ok, so let me see if I understand. You know a WebSite where you can
download mp3 files from. Then do you play them in something like Media Player
or Real Player? There are some tools in vb.net or c# or VWD, I think it is in
the Framework so likely in all 3, that will do exactly that. I download
Websites and parse information or use csv files but have not downloaded a mp3
file. I think there is a standard command or a set of commands, that download
files and save them in folders if that is what you are trying to do.As you
mentioned all you do is hard code the leading url that is the same then change
that part of it that indicates which file you want based on time I think it
was. You make it a string and call the method to download that file into a
folder and that should be about all there is to it. You can pop up a MessageBox
when done but it really shouldn't take very long if you are using a high speed
internet connection. Also, as you mentioned, you could put what you want into
an array or just iterate through some inputs and download several at one time.
That way you might be able to download say the Morning, AfternNoon and Evening
news or whatever and then play them at your convenience. Too advanced for what
I have in mind but send me a message off list and I will help you get it
working. I will have to do a little reading on downloading audio files to see
if there are any complications. Send me a message at:
ofbgmail@xxxxxxxxx
and we can get started. I forget, did you want to work in Vb.net or C#?
I prefer vb.net since I am way more familiar with that language and have
examples in Vb.net of doing similar things.

This sounds interesting. I have just the perfect small project, maybe a
baby step. I attempted it in VB Script, but can't figure out fixing the bugs. I
made a show downloader to download this show I like who absolutely requires
Itunes to do it the automatic way, Juice won't work, adding it to podcast
directories breaks them, a bad feed, but that's how whatever system their
station uses must put out. The file names aren't random, and the big long
akamai url blob at the front is the same, so we can make the hour and date as
variables to make it work. We have something like
showname%205-19-10%2012pm.mp3. The same format is used for 1pm and 2pm. In the
.bvs script I just used an array to cover making it download all 3 hours, and
the date was entered into an input box tied to a variable. With this x-http dll
I registered, it worked, but it was buggy. First, there was no indication that
it was doing anything, the script goes to the background like a service, only
seen by wscript.exe as a process name, didn't intend to do that. I had an it's
done sort of message box when it finished so 20 minutes later, and I have
18mbps Uverse, why x-http takes longer than the old manual way clicking links
in the browser, it was done. The path to save was hard-coded, maybe I'd like to
change that, and if there was a way, I'd like to just have it download a range
of dates if I miss several days.
