Debugging is a major part of the development lifecycle. Sometimes challenging, sometimes puzzling, sometimes annoying, one for sure - it is unavoidable for any not-so-trivial program. The progress of debugging tools over the last years has made many debugging tasks much easier and less time-consuming.
This article summarizes 10 debugging tricks and techniques that can save you a lof of time when using Visual Studio.
If you’re excited about HTML5, I want to help you turn that excitement into ideas you can put into practice immediately. If you’re skeptical, I want to help you understand just why HTML5 is important.

HTML5 applications are obviously written using JavaScript. But compared to other kinds of development environments (like native ones), JavaScript historically suffers from an important limitation: all its execution process remains inside a unique thread.
This could be pretty annoying with today’s multi-core processors like the i5/i7 containing up to 8 logical CPUs—and even with the latest ARM mobile processors being dual or even quad-cores. Hopefully, we’re going to see that HTML5 offers the Web a better way to handle these new, marvelous processors to help you embrace a new generation of Web applications.
I’ve decided to use EaselJS which was used to write PiratesLoveDaisies, a great HTML5 Tower Defense game. We’re going to see in this tutorial how to use your existing sprite elements and animate them.
In this article, we’ll elaborate how to call methods asynchronously. As we all know, delegates are used to call methods asynchronously, but here we’ll combine asynchronous function calling and the event handling concept for achieving Asynchronous Processing. To avoid confusion, let’s define what we are going to do in this example shortly.
- We’ll develop a Task class that contains an
IterateFile()method and three events –StatusEvent,Complete,ProgressChanged.StatusEventwill keep track of the file status during file processing. The Complete event is raised when file processing completes. TheProgressChangedevent is raised when the iteration completes.- We’ll also develop the
FileProcessingclass that contains theProcessing()method andStatusEvent.StatusEventis raised when file processing status changes.- We’ll have a Windows Form that displays all this information.
Most of us at one time or another has used Facebook to share a URL link. When you did, you might have noticed that Facebook gives a "preview" of the site contained in the URL. Recently having a need for a user control that does something similar, I tried looking around the Internet for something similar but with no luck. So that is what inspired me to write this user control. The control presented here is a complete multithreaded website previewer, complete with multiple image control.
Today, we are going to provide the Top 5 Best 10-inch Android Tablets You Must Buy in this New year 2012. All these devices are loaded with high end configurations to deliver extreme performance and all this tablet will definitely satisfy all you needs without any compromise.A lot of companies announced various tablets that are not on market even after a few months after the initial announcement. The strongest sub-niche is the 10 inch tablet, which currently features the Apple iPad 2 at the crown (its screen is actually 9.7 inches) plus a lot of Android tablets trailing it, models that look really interesting and have raised consumer’s attention to this growing segment making for a sizable percentage of the 2011 sales. 2012 is expected to see new members from the Windows 8 family, but right now the ten inch tablet niche is dominated by iOS and Android models (Honeycomb and Ice Cream Sandwich). Here's a list of best 10'inch Android Tabs.

Introduction to article by Meshack MusundiI have on several occasions scoured the net for a simple to use WPF webcam control and either my search queries were awful or I just wasn't comfortable with whatever I found. This webcam interest was recently increased when I read an article, here on CodeProject, that referred to an application that made use of a webcam. It was a Silverlight article and the ease with which one could utilize a webcam in Silverlight made me envious of WPF's little brother (or is it sister?). The VideoBrush in Silverlight is especially a nice touch.
It is with this pain and envy in mind that I decided to try my hand at creating a WPF control that could;
- Display webcam video with little coding effort
- Allow saving of webcam video to harddisk, with little coding effort
- Save the webcam video in a variety of video formats
Simple but presentable message boxes for Silverlight developers. Designed for ease of integration with existing projects
GIFs are one of the oldest image formats used on the web. Throughout their history, they have served a huge variety of purposes, from functional to entertainment. Now, 25 years after the first GIF was created, they are experiencing an explosion of interest and innovation that is pushing them into the terrain of art. In this episode of Off Book, we chart their history, explore the hotbed of GIF creativity on Tumblr, and talk to two teams of GIF artists who are evolving the form into powerful new visual experiences.
