Windows Phone 7.5 - Manipulating camera stream In the previous article from this series I've introduced how to access the cameras of the phone and emulate a photo camera using the Windows Phone API. These API are really straightforward and almost everyone can take pictures easily for the purposes of the application. But for the most demanding, taking pictures does not suffice. As an example you can think to an application that needs to measure the light incoming from the lens or that is able to read a barcode without asking the user to click a button. These two samples, but also lot of other I can imagine, require the access to the raw stream coming from the camera. Only in this way the developer can examine the stream, detect shapes, perform calculations, and so on. Download the source code Accessing the raw stream For the purpose of demonstrating how to access the camera stream, I've created a simple histogram calculator app. 1: public Histogram() 3: InitializeComponent(); 5: // add here further initializations 14: else
Débuter avec une carte Arduino La famille Arduino est apparue en 2006 sous forme d’une carte programmable avec un port série. Puis de nouvelles versions sont apparues, toujours aussi simples, avec différents formats : petites, grandes, plus puissantes, plus économiques, avec USB, avec Ethernet, compatible Androïd, etc... On peut les utiliser pour récupérer les informations de capteurs, pour contrôler des moteurs, pour communiquer avec un ordinateur, avec un téléphone portable, pour envoyer et lire des messages sur Internet, pour éteindre des appareils électriques, pour piloter un robot mobile, pour servir de cerveau à un humanoïde, ou tout simplement pour apprendre l’électronique, et encore bien d’autres usages. Retrouvez grâce au lexique tous nos articles traitant de la carte Arduino. Arduino, c’est une grande famille et une solution reconnue avec des publications dédiées. Différents modèles, une même passion Présentation Voici ses caractéristiques principales pour le modèle le plus courant : hardware software Premiers pas
Interview Questions Open Database - GeekInterview HTML5 - Web developer guides HTML5 is the latest evolution of the standard that defines HTML. The term represents two different concepts. It is a new version of the language HTML, with new elements, attributes, and behaviors, and a larger set of technologies that allows the building of more diverse and powerful Web sites and applications. This set is sometimes called HTML5 & friends and often shortened to just HTML5. Designed to be usable by all Open Web developers, this reference page links to numerous resources about HTML5 technologies, classified into several groups based on their function.

Native, HTML5, or Hybrid: Understanding Your Mobile Application Development Options Navigation: Developer Force | Salesforce Mobile Services | Native, HTML5 or Hybrid Screens are small, apps are big, and life as we know it is on its head again. In a world that's increasingly social and open, mobile apps play a vital role, and have changed the focus from what's on the Web, to the apps on our mobile device. Mobile apps are no longer an option, they're an imperative. You need a mobile app, but where do you start? Like Goldilocks, you may have to try a couple beds that are too soft or too hard, before you find the one that’s just right. While this article addresses mobile app development in general, it is specifically targeted at developers looking to create mobile applications that interact with Salesforce.com, Force.com, or Database.com. Native apps are specific to a given mobile platform (iOS or Android) using the development tools and language that the respective platform supports (e.g., Xcode and Objective-C with iOS, Eclipse and Java with Android).
Writing user defined functions for Excel in .NET - .NET4Office I've updated this article with some new guidance--for the details, see this post. Excel enables the creation of user defined functions that can be used in Excel formulas. A developer must create a special kind of DLL called an XLL. Fortunately, there is an easier way to create a user defined function that doesn’t require you to create an XLL dll. First, launch Visual Studio 2005 or Visual Studio 2008 and create a new C# class library project called AutomationAddin for this example. Then, in your Class1.cs file, enter the code shown below. using System;using System.Runtime.InteropServices;using Microsoft.Win32; namespace AutomationAddin{ // Replace the Guid below with your own guid that // you generate using Create GUID from the Tools menu [Guid("5268ABE2-9B09-439d-BE97-2EA60E103EF6")] [ClassInterface(ClassInterfaceType.AutoDual)] [ComVisible(true)] public class MyFunctions { public MyFunctions() { return result; } Registry.ClassesRoot.CreateSubKey( GetSubKeyName(type, "Programmable")); 1. 2.
