I was using an XSL style sheet to do the sorting but it seems to be very slow. Is there a more efficient way? It is a flat list of nodes, if I convert the nodes to an object and sort in a GenericList would it help? EDIT I don't need the end result to be XML. ...
I have a web application that allows a user to search on some criteria, select an object, edit it and then return to the previous search. All the editing takes place on a separate page linked to the datagrid of returned results.

I'm using .NET typed datasets on a project, and I often get into situations where I prefetch data from several tables into a dataset and then pass that dataset to several methods for processing. It seems cleaner to let each method decide exactly which data it needs and then load the data itself. However, several of the methods work with ...

I've been trying to compare the memory footprint between a VB6 application and .Net application. Trying to determine what's the average difference between the two. The .Net code is for the most part a direct translation of the VB6 and for the most part has the same instructions as they would be programmed in C#. So while it's an apple t...
As a developer who is always looking for new resources and information, I loved Mike Gunderloy's blog "The Daily Grind" on www.larkware.com ("We get up early, so you don't have to.") Unfortunately (for me) Mike decided to discontinue the blog in December 2007. So, my question: is there a similar blog / site which provides such good link...

How can I make a SQL Compact 2008 application for the desktop? I know how to connect to a .SDF file with SQL Management Studio 2008, but I can't figure out how to connect to it with my app. I have seen tutorials about this and I can see in the C# code they are referencing some special namespaces, but I can't seem to get it to work. Wh...
Currently I'm using var x = dict.ContainsKey(key) ? dict[key] : defaultValue I'd like some way to have dictionary[key] return null for nonexistant keys, so I could write something like var x = dict[key] ?? defaultValue; this also winds up being part of linq queries etc. so I'd prefer one-line solutions. ...
I am going to be making an application that lets users input several parameters for a bowling ball layout, and then show what that layout would look like on the ball. I have found some good resources for sphere math, so if I have a sphere whose center is (0,0,0), I will be able to get the values of the points I need on the surface of th...

I've done numerous searches and I realize that I can just download this file and install it either in windows/system32 or in the application's directory. My question is, how does this dll generally get installed on Vista? I tried installing the .net framework 3.5 and it didn't get installed with that. Background: I'm running a java.jar...
