This article is a contribution to the Code Lean and Mean challenge. The competition presentation states: In days of yore, it was a badge of honour to be able to fit a full file manager, spreadsheet application, appointment reminder, and Tetris Easter Egg within a 32KB executable....

A Generic - Reusable Diff Algorithm in C#  Version: 0.00     Price: $0.00

This is a generic algorithm for finding the difference between 2 objects, no matter what the type. The algorithm uses the ICompare interface to tell if the items are the same. Maybe this could be used for producing a WiKi site in ASP.NET and track revisions. I just wanted to let all you readers know, I don't have a degree in Computer Science and I haven't read or learned much about algorithm design. I haven't ever really analyzed a Diff algorithm before, but I know a little about them. If there ...

This is my entry in the Code Lean and Mean Contest. The idea of the contest is basically to create the leanest and meanest file diff program that can show the differences of Grid1.html and Grid2.html, running as fast as possible and using the least amount of memory. This article is obviously for the C++ contest which seems to have less entries than the C# category....

This article describes how to numerically solve a set of second order differential equations with initial conditions. Nystr?m modification of the fourth order Runge-Kutta method is explained first. Then the method is applied to two problems: to find the trajectory of a flying projectile and to calculate coupled oscillations of a mechanical system with two degrees of freedom. The article is intended as a continuation of my previous article about solitary differential equations....

This is a candidate entry for The Code Project's Lean and Mean competition to write an efficient text delta tool.

I was checking my emails while on vacation and I came across a Code Project daily mailing with a reminder for the LCS competition. I have enjoyed reading The Code Project articles for many years now, but until this moment I never had the opportunity to contribute....

This article is an examination of the basic greedy diff algorithm, as described by Eugene W. Myers in his paper, "An O(ND) Difference Algorithm and Its Variations". It was published in the journal "Algorithmica" in November 1986. The paper is available as a PDF here[^].

In his paper, Myers also extends his basic algorithm with the "Linear Space Refinement". This requires a sound understanding of the basic algorithm as described in this article. It is examined in part II, which is also ava...

This article is an entry for the Lean and Mean competition, which ran on The Code Project during August 2009.

It is my third entry after NLineDiff and NLineDiffConsole.

The second test file, "grid2.html", says there are 5 changes. I still haven't found the last one: "A non-visible change to the underlying HTML markup", but I thought I could do a better job of the "visible text change", which is the insertion of " lang="Text"" in line 172 of grid2.html and the "linebreak removal" at...

Linear discriminant analysis (LDA) is a method used in statistics and machine learning to find a linear combination of features which best characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification....

I need to include files from a sibling directory under a virtual directory from two different sibling subdirectories, yet make sure parent paths stay disabled (see Figure 1). The virtual include is relative to the root, so I need to know the full path \vdirTwo\subInclude\MyInclude.asp. I want to be able to include just \subInclude\MyInclude.asp from either sibling directory so the include doesn't have to be duplicated in child directories, but I want to do it without parent paths turned on....

XML is widely used for storing and formatting data. By using the current APIs, it is slightly cumbersome to handle and play with XML data.

When using Microsoft Outlook, you come across a mail notification window that appears slowly and fades off. But, when you drop your mouse back on the window, it becomes opaque, and then again on mouse away it fades off, and this process continues so on. So, eventually it either fades away or you ignore the window, or you close it or you click it to read the mail. This article describes how to build that kind of window using C#....

What exactly are lambda expressions in C#?

I while ago I watched a very interesting Channel 9 video with Erik Meijer and Charles Torre. The video is about functional programming and why that is important in the multi-core world. They talk also about LINQ and lambda expressions and by the end of the video Erik mentions that he often gets the question about what lambda expression exactly are (in C#). So what are they? To understand that we should probably go a little bit back in time. Let’s go back to the time of .NET 1.0 (C# 1.0) and star...

Using a custom VirtualPathProvider can cause OutOfMemoryExceptions

Read Reviews | Write Review |  Your Rating: 

Virtual path providers are awesome - you can serve a site from a .zip file, perform XSLT transformations to generate .aspx files as the compiler reads them, and do all sorts of unusual things. However, using them can make the StaticFileHandler buffer entire downloads in memory before sending the data to the client. (StaticFileHandler is used instead of an IIS callback (ExecuteUrl) if HTTP headers or cache policy has been modified during the pipeline)....

DNS.NET Resolver (C#)

One of the things I needed to complete my self-written spamstopper, which acts like an SMTP proxy, is resolving DNS queries, reading SPF1 records, doing reversed lookups etc. On the .NET (2.0) framework there is a simple implementation of a DNS component. But it was far from complete. The other project on DNS resolving on CodeProject, C# .NET DNS query component, By Rob Philpott is old, buggy, incomplete and not supported anymore. It was time to take the official RFC's on DNS and building the ap...
