OK, I made another post that has the exe file in them. Here is a link to that post. Go to the bottom of the post and download the zip files. Simply put the two files in the zip in their own directory and make a shortcut to the exe file. BTW, I’ve tested these files with both XP and Vista. If anyone else is using another OS, please post your results.

Got the host file changed, as other poster – no exe, plus does this work on XP?

There is no exe file in the project. You must build it. I’ve sent you an exe as a separate email.

Peter,
I got Mike’s gadget working fine and downloaded your .zip file. However, I don’t see an .exe file anywhere in the TivoSummaries folder. Am I missing something on this install?
Thanks.

Just a quick note that makes installation easier. You can simply put your IP address of your TiVo in the service number field and then you don’t have to mess with your hosts file. I’ll fix this and make a new post after I’ve got several other changes incorporated (Like Fabrice’s in the previous comment).

Nice work, Peter! Impressive.

Your blog engine removed the angle brackets. The method’s signature should be:
public static IDictionary[String, Int64] GetSpaceByCategory(String xmlString)
where the square brackets represent angle brackets.

Peter, good work.
Here is how you can further improve your code.

public static IDictionary GetSpaceByCategory(String xmlString)
{
XNamespace ns1 = “http://www.tivo.com/developer/calypso-protocol-1.6/”;
XElement root;

using (StringReader stringReader = new StringReader(xmlString))
{
root = XElement.Load(stringReader);

var shows =
from item in root.Elements(ns1 + “Item”)
let details = item.Element(ns1 + “Details”)
let links = item.Element(ns1 + “Links”)
where links.HasElements == true
let customIcon = links.Element(ns1 + “CustomIcon”)
where customIcon != null
select new TivoShowInfo
{
Title = (String)details.Element(ns1 + “Title”),
Duration = (Int32)details.Element(ns1 + “Duration”),
NumberBytes = (Int64)details.Element(ns1 + “SourceSize”),
ShowType = (String)customIcon.Element(ns1 + “Url”)
};

Int64 totalBytes = shows.Sum(show => show.NumberBytes);

var categories =
from s in shows
group s by s.ShowType into g
select
new
{
ShowType1 = g.Key,
TotalBytes = g.Sum(s => s.NumberBytes)
};

var result = categories.ToDictionary(cat => cat.ShowType1, cat => cat.TotalBytes);
return result;
}
}

This is only GetSpaceByCategory, but it’s your main method.
For it to work this way, all you need is to add a parameterless constructor to your TivoShowInfo class. You could also use the current constructor in the query if you prefer.

Great job, Peter. This is a fantastic way to view the space on your TiVo. I learned a bit about LINQ too!
