Anyone out there know how this should be written in VB.Net? (the problem spot is the "select new {...") PeopleData...
I use log4net all the time, but one thing I've never figured out is how to tell what's going on on the inside. For example, I've got a console appender and a database appender in my project. I made a few changes to the database and the code, and now the database appender doesn't work anymore. I'll figure out why eventually, but it would ...
We have an application that stores a sparse matrix. This matrix has entries that mostly exist around the main diagonal of the matrix. I was wondering if there were any efficient algorithms (or existing libraries) that can efficiently handle sparse matrices of this kind?

I have a very strange requirement using DataTable. I have a datatable with some columns. Nwo whenever there is any change in any of the DataRow in the datatable; then the state of DataRow is set to modified. That is OK. But for one exceptional column I don't want this behavior. I want that any change in any row for this particular column...

I would like to introduce unit testing to our C++ product and wanted to investigate the pros and cons of trying to use the CLR-based unit tests. I've read that if you compile with the /clr:safe option, you can call your existing C++ code. I'm strictly a .NET developer, so I'm at a loss for how this would affect our codebase. What shou...
Does the absolute value protect the following code from the Environment.TickCount wrap? If Math.Abs((Environment.TickCount And Int32.MaxValue) - StartTime) > Interval Then StartTime = (Environment.TickCount And Int32.MaxValue) . . . End If Is there a better method of guarding against the Environment.TickCount() wrap? (This ...
The situation is as follows. public interface IFoo { } public abstract class FooBase : IFoo { } Now I need a collection of IFoo with some additional methods. public class IFooCollection : List<IFoo> { public void UsefullMethod() { } } The problem is that IFooCollection looks like an interface while it is a class.

I'm using ASP.Net AJAX and I created a web service in my application. The service has one method (AddWatchedFolder) and it takes a Name.Space.WatchedFolder as the only parameter. The problem is, ASP.Net AJAX isn't generating a javascript type for Name.Space.WatchedFolder even though I've added the service to a ScriptManager. I am able t...
Edit: I have asked question to understand why C# designers chose it to behave in particular fashion? Similar question has been asked, but this is little different. Should following code give warning? class Foo { public void Do() { /*...*/ } /*...*/ } class Bar : Foo { public static void Do() { /*...*/ } /*...*/ } It gives: "warning...

My objective is to move visual elements drawn using methods of a Graphics object across a Form with no flicker or artifacting (in .NET 3.5). I can successfully achieve flickerless movement by either using automatic double buffering (setting the Form's DoubleBuffered property to true) or implementing a back-buffer myself. I am however s...
