Race Condition & Synchronization in C# - Coding N Design
We have heard about the term race condition in relation to threads.This is basically a scenario where two or more threads are competing(racing) to read/write from a shared memory location leading to the possibilities of leaving the program in an inconsistent state. Consider the program shown below: public class A { public int x = 0; public int y = 0... (more)

Single Assignment & readonly Fields in C# - Coding N Design
We have all heard about immutable objects, the objects whose field values cannot be altered throughout it’s lifetime.Immutable objects are simpler to deal with in case concurrent programs where they can be shared between multiple threads.The single assignment variables variables which is once assigned a value cannot be reassigned again.These are inherently immut...

Programmer's Blog: How to track visitors to your site in ASP.NET & C#
Once you have published a site in ASP.NET, you'd like to know who are your visitors. One way is to check your event log on the host server. Another option is to write your own code. You'd basically like to log the IP address, and DNS name for the visitor, and it would be nice to know which page they are visiting. To log the ip address using ASP.NET, you can call: Request.ServerVariables["HTTPXFORWARDED_FOR"] Another usefull variable is Request.ServerVariables["REMOTE_ADDR"] A combination of the ... (more)

Programmer's Blog: C# how to open a file that is locked by another process
If the file is locked by the process exclusively, it is not possible to open those files. But if the process holds only shared lock, we can open the file using c# using the following code, FileStream objf = new FileStream(”Ouput.xls”, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); Excel hold the shared lock on the files. The Following is an example program to read a file, using System.IO; public static byte[] ReadFile(string filePath){byte[] buffer;FileStream fileStream = newFileStream(... (more)

Programmer's Blog: Implementing the Repository Pattern in C# ASP .NET
Introduction Writing a C# ASP .NET web application which utilizes a database can create increasingly complex code. The more complex code gets, the more difficult it becomes to debug, maintain, and enhance. The Repository design pattern is a way of introducing architecture into your C# ASP .NET web application, which creates a clear layer of separation between your web forms and database accessible layers. The Repository pattern helps organize a web application to form a 3-tier architecture and provide... (more)

Programmer's Blog: C# yield operator
Prior to .NET 2.0, the only way you could create your own collection which could be traversed using the 'foreach' construct was by having you class implementing the IEnumerable and IEnumerator Interfaces. However since .NET 2.0 we have a new operator called 'yield'. This allows your class to be iterated by its consumer but without the need to implement the above-mentioned interfaces. Let us see a small example of how this works: // Our class does not implement any interface ! public class Sch... (more)
