FIR stands for Finite Impulse Response.

In the analogue world, if you wished to filter a signal, you would use capacitors, resistors and inductors wired together to create the filter of your choice. In the digital world, you can still apply a filter to a sampled signal being received by a method of multiplying the samples by as series of coefficients and summing to create a new (filtered) sample stream....

Sometimes you want your application to run single instance. For example, if you wrote a server application you probably only want a single instance to run at a time on the localhost.

This code was developed primarily for a server application running on a Win2KPro Multi-Processor server. It is intended to make absolutely certain that only one instance of the application runs at a time regardless of logged on users. The code detects all processes running in all desktops and all service exec...

There are many, many examples of how to do encryption and decryption in .NET. So why one more? Well, for one thing, I find that the majority of good code examples of any type are issued in C#. This isn't surprising, since those from a C++ or Java background will have an easier transition to C# than a similarly experienced Visual Basic developer moving to VB.NET. It will take time for the VB.NET community to develop into what the C++ and Java community already has at its disposal. So, I thought t...

Since I am learning C#, I thought it would be helpful for me to port my C++ CTaskbarNotifier class (http://www.codeproject.com/dialog/TaskbarNotifier.asp[ ^])

As a result, I coded a MSN Messenger-like skinnable popup, with a close button which looks almost like Microsoft's one (with the associated skin).

The TaskbarNotifier class inherits from System.Windows.Forms.Form and adds a few methods to it....

When using an OpenFileDialog in .NET, it is often useful to be able to ascertain if the file selected resides on a network drive. If this is the case and you will be storing the file path for others to use (in a database for example), then you are relying on all users having the same drives mapped to the same letters....

We know that most of the times MTS objects are stateless. But sometimes it becomes necessary to persist properties or state of the object. MTS provides this functionality via Shared Property Manager.

There are three objects which we need to deal with :

* SharedPropertyManager
* SharedPropertyGroup
* SharedProperty

SharedPropertyManager is at top level in the hierarchy. It allows a property to be shared across multiple clients....

In the Part 2 of this series we learnt to use Secret Key Encryption techniques using Triple-DES algorithm. More often to transfer data encrypted via secret key encryption public key encryption is used. This puts one extra layer of security over the data being transferred. From Part 1 we know that public key encryption consists of two keys - public key and private key. Data encrypted by public key can be decrypted only by the corresponding private key and vice a versa. One of the most popular alg...

When browsing the web using your mobile phone, it will generally be receiving web content in a format called WML (Wireless Markup Language). This is a derivative of XML, specific to wireless devices. It displays content in a manner suitable for the small screen on a mobile phone. When these WML pages are sent from the network to the phone, the pages are compressed to reduce the number of bytes required for transmission (and hence the cost of the download to the customer) and also to generally sp...
