Binary Trees are tree type data structures that contain two child nodes. They can be used to implement Binary Search trees, structures where the left child has a value lesser than the node and the right child has a greater value. Usually Linear collection objects require iteration linearly over the list. In the [...]

Though MVC is an age old architectural style that has existed since the 70s, its a relatively new entrant in the .NET world. I had written a general introduction about MVC earlier. That post is available here. While Java, Ruby, Python all had their MVC frameworks for quite some time, ASP.NET was quite comfortable [...] In continuation to my earlier post about multithreading in .NET, I am writing about the ReaderWriterLock class which is one more method of thread synchronization. The ReaderWriterLock is based on the fact that the Monitor locking (lock keyword in C#) doesnt really make any distinction whether the thread accessing the variable is [...] I got an interesting problem by email recently where someone had asked me to solve the given below problem:- A squad of robotic rovers are to be landed by NASA on a plateau on Mars.This plateau, which is curiously rectangular, must be navigated by therovers so that their on-board cameras can get a complete view of [...] How often have you faced the irritating not responding screen while the application waits for the data that you requested for. The problem is not with bad code or a slow database, the problem with conventional applications is that all the code is executed on a single thread. i.e. whenever an operation is [...] Events and Delegates are quite tied together in .NET, but there are differences in terms of usage. Events are implemented through delegates, but they are not quite interchangeable. The event keyword is an access modifier on the delegate which restricts its usage outside the class which it belongs to. First the similarities. [...] In the previous post we saw how anonymous methods can help reduce verbose delegate code. With C# 3.0, there was a new language feature introduced which further reduces the delegate code – Lambda expressions. Lambda expressions use automatic type inference, which relieves you of explicitly declaring the type. Here is a simple example of lambda [...] Anonymous methods are a convenient way of using delegates in .NET 2.0 and above. For e.g. if we use a delegate for a simple 2-3 line functionality, declaring a separate method and then passing the target to the delegate seems like overkill. Anonymous methods provide an easy way out, just declare the body [...] The word Asynchronous means something that is not synchronized (duh!!) i.e. which occurs out of step and is not coordinated. In programming parlance, asynchronous processes are which take place independently of other processes. For e.g. a method call. A conventional method call is blocking. i.e the calling thread waits for the method to [...] I didn’t know this was possible until a few days back when a user asked about it on one of the MSDN forums. The query was on how to integrate Winforms and WPF i.e. how to display WPF user controls in Winform application. This feature can be extremely useful because some elements [...] |
