The sliding scale is a very simple, but fast, performing, and powerful .NET user control, figured as a graphical scale gauge with a linear representation of data. The instrument consists of a static pointer (needle) and a movable linear scale. The static needle refers to the current position of the moving scale, and shows the input values through a graphical position along the scale. The sliding scale is endless, and can represent an unlimited value (type double) at a certain moment....

Here are a couple of really cool methods that makes it very easy to sort generic List s and IEnumerable collections by the collection item object property name. I was working on a project and needed to bind a generic list to a GridView control. I was dynamically binding the list, and I needed an easy way to change the list sort using only a property name. I came up with a couple of methods that makes this really easy. The first method allows you to directly sort a generic List<> object using Ref...

Pop-up windows are everywhere. Each tooltip is a pop-up window; each combobox has its pop-up list; many advertisements are also shown in pop-up windows. At first, we might choose the Form class as a base class for our pop-up control. Unfortunately, it's a bad choice because when we show our pop-up form, the parent form loses its focus. A pop-up window shouldn't cause that. Luckily, there is a class that does not cause loss of focus. We can use it as a base class for our pop-up control. It's the ...

Ihave long extolled the virtues of the asynchronous programming model (APM), emphasizing that performing I/O-bound operations asynchronously is the key to producing scalable and responsive applications and components. Achieving these goals is possible because the APM allows you to use a very small number of threads to execute a large amount of work without blocking any of the threads. Unfortunately, using the APM to build a typical application or component is difficult, so many programmers just ...

Have you ever opened a file stream with FileShare.None so that external programs could not alter its contents, only to be frustrated when other parts of your same program needed to open the file in read mode? Have you ever wanted to read data from a binary file that contains a fixed size header and treat the data section as if it were a standalone stream? Have you ever been given a COM stream and needed to use it in multiple places but couldn't? I have! In the past, I had developed a kludgy code...

Google Web Toolkit is a Web Application Framework dealing with Servers and Clients. When a Server is required to do some processing in a web-app Services must be used. A service is used to invoke server-side code from the client (and vice-versa occasionally).
In GWT the Client side code pages run more like an application within the Client (Browser), so requesting the HTML pages from the Server is not necessary. But in common with all Server-Client Architectures, even GWT needs to contact the ...

Abstract class is a class that has no direct instances, but whose descendants may have direct instances. There are case i which it is useful to define classes for which the programmer never intends to instantiate any objects; because such classes normally are used as bae-classes in inheritance hierarchies, we call such classes abstract classes These classes cannot be used to instantiate objects; because abstract classes are incomplete. Derived classes called concrete classesmust define the missi...

At times you need to define a class only to serve other class and there are no other reasons to make it visible. The best way to implement this is through nested classes. A nested class is a class defined within the scope of another class....

Wireshark is a powerful open source tool used to dissect Ethernet packets. Have you ever wondered what it takes to implement your own custom dissector? Furthermore, have you attempted to learn Wireshark's API and found it difficult to understand? This article will attempt to demystify the development of your very own protocol dissector. This article uses Amin Gholiha's "A Simple IOCP Server/Client class," as a basis for dissection, thus producing the AMIN protocol....

One of my recent projects at Raizlabs required the distribution of PHP software to customers as a trial demo. We wanted to allow customers to demo the software before they committed to a purchase. To limit piracy, we wanted to protect the PHP code itself.
We looked into various solutions for PHP source code protection, among them other open source encoders and obfuscators, as well as some closed source byte-code compilers. Our issue with the byte-code compilers was that in every case, the...

In a world where disconnected systems are the norm, and guaranteed delivery is crucial, asynchronous processing is a godsend. Your ecommerce system can accept an order online, fire off a message, forget about it, and send the customer on his merry way. Your billing system can be notified, along with your inventory system, as well as your delivery system, all from a single message or file. Life is good. OK, so life is good if you have a way to capture that message or file and process it. I can re...

The histogram in the context of image processing is the operation by which the occurrences of each intensity value in the image is shown. Normally, the histogram is a graph showing the number of pixels in an image at each different intensity value found in that image. For an 8-bit grayscale image there are 256 different possible intensities, and so the histogram will graphically display 256 numbers showing the distribution of pixels amongst those grayscale values. More about the histogram can be...

Hello! This is my first article, and I'm a medium-level begginer at C#. I has nothing to do one day so I thought it would be nice to create a basic Office 2007 Style Ribbon with all 3 styles. I hope you enjoy this. I can't seem to render some of the ribbon though, and it usually flickers when you mess with it. This contains a couple of controls, so I'll walk you through some of them....
