  • Chromium et Qt rassemblés dans QtWebEngine, un prototype intègre le navigateur open source dans des interfaces Qt Quick

    Un certain temps après le port de Firefox sur Qt en lieu et place de GTK+, c'est au tour de Chromium, la version open source du navigateur Web de Google, d'être le sujet d'expérimentations. Ce projet ne se compose pas que d'un moteur de rendu, il s'agit d'une implémentation complète d'une plateforme Web, de la pile de protocoles réseau au framework multimédia, le tout disponible sur un grand nombre de plateformes (tout comme Qt). L'objectif récemment poursuivi par des employés de Digia était de laisser des développeurs Qt utiliser des briques de l'environnement Chromium, au sein même de Qt Quick 2 et des widgets. Il s'agi...

  • Vos applications valident-elles correctement les adresses e-mail ? Retour sur les détails des spécifications

    Vos applications valident-elles correctement les adresses e-mail ? Retour sur les détails des spécifications Les adresses e-mail sont au coeur de toutes les applications Web. Et s'il y a bien une seule tâche commune à tous les projets de développement Web, c'est la validation de ces adresses. Si cette validation peut sembler au premier abord simple, facilement accomplie par le test de conformité à une expression rationnelle, beaucoup de développeurs ignorent les détails des spécifications et risquent de rejeter des utilisateurs aux adresses e-mail peu habituelles certes, mais tout à fait conformes. Le problème vient essentiellement du fait que les spécifications...

  • AntClassLoader bug exposed by forgetful NetBeans

    - by vbkraemer
    Many users have run into ClassNotFoundExceptions and NoClassDefFoundErrors after working with web services that target GlassFish while developing their projects in NetBeans. The issue usually appears as a dialog similar to this This can be pretty debilitating. The bug appears to be in the AntClassLoader, which is tickled by the wsimport ant task that ships with GlassFish 3.1.2. The fix is pretty simple: Upgrade the Metro bits that ship in 3.1.2 with bits that have had a patch applied. There are detailed instruction about installing the updated Metro bits onto GlassFish. This upgrade is probably useful for any install of GlassFish 3.1, but it is critically important for folks that develop web services from inside NetBeans and deploy them onto GlassFish 3.1.2.

  • DXperience v2010 vol 2 Review

    - by kulrom
    Hi guys, this is my second review of these controls, and it will be quite different than the first. A few months ago I was engaged by a client to develop a web based application. He asked me (I guess they all ask the same) to make it good looking and attractive. The first thing I thought of when I heard this was "I must renew my DXperience subscription". And now I am glad I did that. Before I continue, I would like to say something to those readers who are totally new to DXperience. Guys, we all know that one of the more frustrating things for the ASP.NET developers is designing the good looking application. Well folks, your troubles are over! The DXperience takes much of the agony out of developing and designing an outstanding web application. Here we go!...(read more)

  • .net- open excel file, format the file and save

    - by Lock
    I have an ASP web service that uses the Crystal Reports API to download an Excel report. Now, there is a few things I do not like about the Excel report that Crystal generates: - The column widths are static (as in they are not adjusted for the content). - I can't format the header row to be bold - If I suppress a data column in the report, it comes out in the Excel spreadsheet as a blank column. I currently use PHP to open the excel file, autosize the columns, bold the heading and remove blank columns, although using the PHPExcel class for this doesn't work well when the spreadsheet is only a few 100kb in size. I am thinking if I move this activity into the .NET web service, the performance will be much better. Does anyone know an efficient way of opening a Excel file and performing the operations listed above?

  • The life saver HttpContext.Current.Items["ParameterName"]

    - by MoezMousavi
    I got stocked passing parameter to one master page for some reasons, seems the page lifecycle and dynamic loading of the master pages has got some issues with defining public properties in the masterpage within my project. It did not set my values and as a result, properties became useless. A collegue just mentioned using HttpContext. have a look what  MSDN saying "Encapsulates all HTTP-specific information about an individual HTTP request" http://msdn.microsoft.com/en-us/library/system.web.httpcontext.aspx HttpContext.Current.Items["ParameterName"] Also, Page.Items could do the same thing. Page.Items, "Gets a list of objects stored in the page context" http://msdn.microsoft.com/en-us/library/system.web.ui.page.items.aspx as your master page and content page are rendered as a single document anyway.

  • New to Maven-- Creating Java EE Projects

    - by M.C.
    Greetings-- I've been developing Java EE web apps with Eclipse for about a year. My employer doesn't use Maven, but the more I read about it, the more convinced I am that Maven + Hudson will be greatly beneficial for us. First, though, I have to become comfortable with those technologies in my spare time, so that I can create a proof-of-concept. Right now, I'm still a Maven newbie. Is there a set of best practices for creating Java EE web apps with Maven? For example, I could create a project with a basic archetype and then add all of the necessary JARs by putting dependencies in the POM for the servlet container, EJB, EclipseLink, etc... That might work, but it might not be the best way to do it. I'd greatly appreciate any guidance that you could provide on this topic. Thank you very much!

  • Part 4 of 4 : Tips/Tricks for Silverlight Developers.

    - by mbcrump
    Part 1 | Part 2 | Part 3 | Part 4 I wanted to create a series of blog post that gets right to the point and is aimed specifically at Silverlight Developers. The most important things I want this series to answer is : What is it?  Why do I care? How do I do it? I hope that you enjoy this series. Let’s get started: Tip/Trick #16) What is it? Find out version information about Silverlight and which WebKit it is using by going to http://issilverlightinstalled.com/scriptverify/. Why do I care? I’ve had those users that its just easier to give them a site and say copy/paste the line that says User Agent in order to troubleshoot a Silverlight problem. I’ve also been debugging my own Silverlight applications and needed an easy way to determine if the plugin is disabled or not. How do I do it: Simply navigate to http://issilverlightinstalled.com/scriptverify/ and hit the Verify button. An example screenshot is located below: Results from Chrome 7 Results from Internet Explorer 8 (With Silverlight Disabled) Tip/Trick #17) What is it? Use Lambdas whenever you can. Why do I care?  It is my personal opinion that code is easier to read using Lambdas after you get past the syntax. How do I do it: For example: You may write code like the following: void MainPage_Loaded(object sender, RoutedEventArgs e) { //Check and see if we have a newer .XAP file on the server Application.Current.CheckAndDownloadUpdateAsync(); Application.Current.CheckAndDownloadUpdateCompleted += new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted); } void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e) { if (e.UpdateAvailable) { MessageBox.Show( "An update has been installed. To see the updates please exit and restart the application"); } } To me this style forces me to look for the other Method to see what the code is actually doing. The style located below is much easier to read in my opinion and does the exact same thing. void MainPage_Loaded(object sender, RoutedEventArgs e) { //Check and see if we have a newer .XAP file on the server Application.Current.CheckAndDownloadUpdateAsync(); Application.Current.CheckAndDownloadUpdateCompleted += (s, e) => { if (e.UpdateAvailable) { MessageBox.Show( "An update has been installed. To see the updates please exit and restart the application"); } }; } Tip/Trick #18) What is it? Prevent development Web Service references from breaking when Visual Studio auto generates a new port number. Why do I care?  We have all been there, we are developing a Silverlight Application and all of a sudden our development web services break. We check and find out that the local port number that Visual Studio assigned has changed and now we need up to update all of our service references. We need a way to stop this. How do I do it: This can actually be prevented with just a few mouse click. Right click on your web solution and goto properties. Click the tab that says, Web. You just need to click the radio button and specify a port number. Now you won’t be bothered with that anymore. Tip/Trick #19) What is it? You can disable the Close Button a ChildWindow. Why do I care?  I wouldn’t blog about it if I hadn’t seen it. Devs trying to override keystrokes to prevent users from closing a Child Window. How do I do it: A property exist on the ChildWindow called “HasCloseButton”, you simply change that to false and your close button is gone. You can delete the “Cancel” button and add some logic to the OK button if you want the user to respond before proceeding. Tip/Trick #20) What is it? Cleanup your XAML. Why do I care?  By removing unneeded namespaces, not naming all of your controls and getting rid of designer markup you can improve code quality and readability. How do I do it: (This is a 3 in one tip) Remove unused Designer markup: 1) Have you ever wondered what the following code snippet does? xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" This code is telling the designer to do something special with this page in “Design mode” Specifically the width and the height of the page. When its running in the browser it will not use this information and it is actually ignored by the XAML parser. In other words, if you don’t need it then delete it. 2) If you are not using a namespace then remove it. In the code sample below, I am using Resharper which will tell me the ones that I’m not using by the grayed out line below. If you don’t have resharper you can look in your XAML and manually remove the unneeded namespaces. 3) Don’t name an control unless you actually need to refer to it in procedural code. If you name a control you will take a slight performance hit that is totally unnecessary if its not being called. <TextBlock Height="23" Text="TextBlock" />   That is the end of the series. I hope that you enjoyed it and please check out Part 1 | Part 2 | Part 3 if your hungry for more.  Subscribe to my feed CodeProject

  • Stores Still Matter In The World Of E-Commerce

    - by Michael Hylton
    You may think that more and more consumers are moving their purchasing to the Web or mobile device.  However, according The NPD Group, Inc., a leading market research company, 15-20 percent of consumers in 2011 checked out products in stores before buying online, or called “showrooming”, for product categories like stand mixers, electric knives, sewing machines, and some floor cleaners. Other categories like power tools, hairsetters, and robotic vacuums are now beginning to show signs of the “showrooming” trend as well. It is doubly important to present a consistent, personalized, and relevant shopping experience for your customers, no matter whether they interact with you in-person in your store, with your sales agents or call center agents, over the Web, or using a mobile device.  Your goal is to make that experience across touchpoints as seamless as possible.

    Java Is an awesome programming language and platform. One of its better features is automatic garbage collection. Ever wondered how that works? I have written an online web course outlining the basics. Much of what is included has been published before in various white papers and such. However, this is updated for JDK 7 and includes some nice illustrations of the steps involved. Hope you like it. Garbage Collection Basics. A follow-on web course on the G1 garbage collector should follow in a week or so.

  • Syncing between computers / batch download

    - by Eric
    I have synced files from two different devices. Now I want to copy to contents of the synced files to the other device. Using the web interface, it seems only possible to download one file at a time. Is there a way to setup automatic sync or to download all the files in a folder with one step? Thanks in advance for your time. I was using the web interface to ubuntu, but an answer for Ubuntu One would also be ok.
