I've been researching a jQuery drag and drop tree plugin for a project that I'm working on and so far I've found the following: 1. jsTree So far this is my favorite. It does almost everything that I want including in place editing of the tree items. One drawback is that it itself requires a ton of plugins...

Great post by Chris Eargle about a null coalescing assignment operator for c# . How would you like to be able to say: myObj ??= new MyObj(); instead of: myObj = myObj ?? new MyObj(); Seems like a trivial "enhancement" to the language but makes sense to me....

I've just learned about the [Flags] attribute for enums. I'm surprised that I hadn't stumbled across it before. Consider the following code snippet: enum Direction { North = 1, East = 2, South = 4, West = 8 } static void EnumTesting() { Direction ne = Direction.North | Direction.East; Console.WriteLine...

I was recently involved in a discussion about IP addresses and discovered that not everyone understands an IP address. I was told that an IP address is not an integer. Well, it is an integer, a 32-bit integer, but it is rarely represented as such. It is usually represented as four octets joined together...

I often need to convert a string IP to an Int32 and then back again. To facilitate converting an Int32 to its string representation I have added this extension method to my IntExtensions class in C#: public static class IntExtensions { /// <summary> /// Converts an integer that represents an IPv4...

I have a Visual Studio solution that's started taking longer and longer to load. In fact it was taking up to 5 minutes to load this solution which meant that I'd leave the solution open for days just so that I didn't have to reload it. Another symptomatic clue that all was not well in Denmark was that...

During a code review I was told that a compiled regex would work faster. I had no doubt that this was true but I wanted to know how much faster and at what cost. I setup and ran the following test. static void TestCompiledRegex() { string regexString = @"(\{{0,1}([0-9a-fA-F]){8}-([0-9a-fA-F]){4...

Following on from Is this string numeric in C# part 2 ... Curiosity got the better of me and I wanted to know what the IsDigit and TryParse functions did. There's a post here by Shawn Burke that details how to setup Visual Studio to allow you to step into the .NET source. From that I found the IsDigit...

Not sure if you were up-to-speed on the compiler version numbering that's been used with C# but just in case you weren't this is what version number the compiler calls itself when run from the \windows\microsoft.net\framework\ folders... (click image to see full size) We went from version 7 to 8 and...
