Since widescreen format in monitors gets more and more common, how about a twist to the classic tabbed windows UI? Imagine being able to pin a tab and have it move to a side-view area in the same window. That are would keep the pinned tabs separated from the rest using a splitter / split-view [...]...

A nice quote from ClipFlair project’s (http://clipflair.net) internal mailing list (the formatting is mine for your convenience): …difference between Dissemination and Impact: Impact is the measure of dissemintation. For example: - Organising a conference is dissemintation. - Number of people attending the conference is impact. - Dissemination is how many e-mails you send. - [...]...

I had such a great time here (as a blogposter). I am moving to biboudis.wordpress.com (update your favorite RSS reader ). I always thought of blogging as a personal public notebook in which I can write some pieces for later reference. This list could be multiplied by 20, if I had taken some time every week to post various things that I liked, I wrote, I met, solved (or not). Some of my posts that I really went back to, at some point, to seek some information were the following. An Extensible WPF client layout with RibbonTab submenus using MEF CloseTabBehavior για TabItems σε Silverlight TabControl A note to self: Silverlight DataBinding awesomeness μέσα από Expression Blend, XAML και ... Silverlight animatable custom controls: quick ‘n’ dirty! [Μαθαίνοντας Design Patterns] Model – View – ViewModel Closures στη C# Πύργοι του Ανόι σε F# Εισαγωγή στα Expression Trees και στις δυναμικές μεθόδους (Visual Studio 2010)...

Below you can find a series of simple demos that can give you a nice insight on the XNA’s power for WP7. All of them are original. Feel free to use them in your code as you wish. There is also a PowerPoint presentation about those demos but unfortunately it is only in Greek. So let the games begin! The basics Demo1 Initializes the game and draws a simple image on the display Demo2 Sprite rotation and movement, Frame rate calculation, writing strings on the display, Demo3 Same as Demo2 but now Frame Rate calculator and bouncing sprite are implemented as game components leading to a more reusable and readable code. Now we can add more bouncing balls in an instant! Parameters are passed to game components through the use of game services Demo4 Multi-touch. Understanding where are the user’s fingers and what they do. A line is drawn and follows each finger that touches the display. The information is passed through game services to the components. Demo5 Gestures. Extending the previous demo to accelerate the...

Based on a nice (but alas not working) idea and as a follow up to my previous post about the fantastic Ext.NET framework [Greek language] today I present you with a how-to guide to Ext JS . First, let me remind you that Ext JS is the powerful JavaScript framework behind Ext.NET . Once again, it is worth mentioning that the Ext.NET guys have done a truly great job wrapping .NET around the JavaScript engine. In this post, we are going to see how we can build a simple HTML page featuring an Ext JS 4 grid that consumes JSON data provided by a server source. Please note that this is a pure AJAX-enabled client side scenario as opposed to the usage of the Ext.NET GridPanel server component. IIS Setup This guide requires you to use IIS as the web server. Before we move on make sure you have a web application set up and ready with the same folder structure as shown in Figure 1. Figure 1. The folder structure of the hosting web application (Tests). The client To begin with, download the Ext JS 4 library (the Open Source...

*** Προσθήκη στις 24/12/2013 *** Σε όλους όσους δεν είναι προγραμματιστές και με ρωτούν αν υπάρχουν δουλειές στους αντίστοιχους κλάδους που τους ενδιαφέρουν, η μόνη απάντηση που μπορώ να δώσω είναι "δυστυχώς δεν γνωρίζω, κ αλύτερα να έρθετε σ' επαφή με την ελληνική κοινότητα στην Ιρλανδία". Η διεύθυνση της ελληνικής κοινότητας είναι: http://www.helleniccommunity.ie/contact Ίσως κάποιος εκεί να μπορεί να σας βοηθήσει. *** Αρχικό κείμενο *** Τον τελευταίο καιρό έχω πάρει πολλά μηνύματα από ανθρώπους που με ρωτούν πώς είναι τα πράγματα στην Ιρλανδία κι αν υπάρχουν ευκαιρίες εργασίας. Σκέφτηκα λοιπόν ότι το θέμα μπορεί να ενδιάφέρει κι άλλους και αποφάσισα να γράψω δημόσια αυτά που λέω ιδιωτικά. Από το ξεκίνημα θέλω να ξεκαθαρίσω ένα πράγμα: όσα αναφέρω βασίζονται στις προσωπικές μου απόψεις και στις προσωπικές μου εμπειρίες, οπότε δεν είναι ούτε αντικειμενικά (με την επιστημονική έννοια), ούτε εγγυημένα, ούτε έχουν καθολική ισχύ. Ιδού λοιπόν μια λίστα με συνηθισμένες ερωτήσεις και τις απαντήσεις τους. Αν κάτι νομίζετε...

Let’s talk about cookies. In fact let’s revisit cookies and see how we use them and what nightmares they bring along. Cookies are all about client storage. They are all about storing persistent information at client side. The syntax for creating/reading them is as follows. Imagine that we want to store client side the value 17 in a cookie named id. This is done by the following BLOCKED SCRIPT document.cookie=”id=17;expires=Mon,6 Feb 2012 12:00:00”; When we later want to read the value of the cookie named id we need to search within document.cookie for the string “id=” and fetch the value up to the next “;” character. Based on the previous definitions we may come up with three nice Javascript functions that make our lives a littler easier: Creating a cookie function SetCookie( name , value, expirationInDays) { var now = new Date (); var expire = new Date (); var newCookie = name + " = " + value; if (expirationInDays != null && expirationInDays != 0) { expire.setTime(now.getTime() + 3600000 * 24...

I saw one of my students do a crazy thing the other day. He and his friends were watching videos on YouTube but with a twist; before each video started they had had its title changed with the help of Firebug (the Firefox’s extension, which allows you to view and manipulate the DOM of a web page). Clearly, they were extremely happy with the results but they knew it wasn’t a permanent thing. But what if it could be? At that very moment, two questions crossed my mind. First, why on earth don’t we just drop the read only nature of web pages? We have excellent tools to play with the DOM and we are comfortable enough with their usage, apparently. Even school kids understand Firebug and Firebug is not a toy, mind you. So, what if we had a Rights Management scheme applied to web pages thus allowing changes by everyone granted with write permissions? But what about dynamic content? Which –somehow, made me ask the second question. Why do we still use online Content Management Systems? Back in the desktop PC era we couldn’t...

Στο σημερινό Sunday’s Dev Digest παρουσιάζω ένα απλό παράδειγμα χρήσης του Ext.NET GridPanel. Τι θα χρειαστούμε : Ένα ASP.NET Empty Web Application (Visual Studio –> File –> New –> Project –> ASP.NET Empty Web Application) Μια ASPX σελίδα (Δεξί κλίκ στο project –> Add –> New Item –> Web Form) Εγκατάσταση του Ext.NET στο project. Ο πιο εύκολος τρόπος είναι να κάνουμε χρήση του NuGet package και στο Package Manager Console (View –> Other Windows –> Package Manager Console) γράφουμε: install-package ext.net Για την χρήση των Ext.NET components στην ASPX σελίδα μας χρειαζόμαστε οπωσδήποτε την δήλωση του Ext.Net Assembly: <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %> και χρήση του Ext.Net ResourceManager component στην αρχή της σελίδας (θεωρείτε, αν θέλετε, τον ResourceManager κάτι σαν τον ScriptManager του ASP.NET AJAX): < ext:ResourceManager runat ="server" /> Το Ext.NET GridPanel Για να χρησιμοποιήσουμε το GridPanel...

Hello Microsoft, can you count?

More importantly, in the popup shown when [...]...

Not too long ago, Microsoft released, NuGet , an automated packagemanager for Visual Studio. NuGet makes it easy to download and installassemblies, and their references, into a Visual Studio project. Theseassemblies, which I loosely refer to as packages, are often open source, andinclude projects such as Nhibernate .In this post, I'll explain how to get started in using NuGet with your projectsto include: installng NuGet, installing/uninstalling Nhibernate via consolecommand, and installing/uninstalling Nhibernate via graphical reference menu. Installing NuGet The first step you'll need to take is to installNuGet. Visit the NuGet site, at http://nuget.org/ , click on the Install NuGet button,and download the NuGet.Tools.vsix installation file, shownbelow. Each browser is different (i.e. FireFox, Chrome, IE, etc),so you might see options to run right away, save to a location, or access to thefile through the browser's download manager. Regardless of how youreceive the NuGet installer, execute the downloaded NuGet.Tools.vsix...

Although a bit outdated its better to publish it now than never. Your eXpand collaborations never stop, so it’s a shame to keep them secret from the rest of the community. Latest Collaborations Logic modules( AdditionalViewControlsProvider , MasterDetail , ConditionalDetailViews , ModelArtifact ) as well as ModelDifference , PivotChart were migrated to the new XAF security system. The new custom permissions are located under the Security.Improved namespace in each module. Out of the box support for support for CachedDataStoreService (see also http://goo.gl/BtYxw ) Minor bugs in MasterDetail, PivotChart, ExceptionHandling An eXpand based version of SecurityDemo solution added to our sources. AdditionalViewsControls now have better support for custom controls (see also http://goo.gl/SyvOz ) eXpand has build in support for Sequence objects and we make it possible to to use a custom one. In addition to the big list of runtime member types we added a new custom member type, which allows to specify an callback which...

Για όσους δεν το γνωρίζουν, είναι το Ext.NET μια φανταστική συλλογή εργαλείων για ASP.NET. Το πρώτο ενδιαφέρον στοιχείο είναι το dual licensing που εκτός της επί πληρωμής Pro έκδοσης περιλαμβάνει την απολύτως δωρεάν Community έκδοση με την οποία μπορείτε να πειραματιστείτε ή/και να την χρησιμοποιήσετε στα προσωπικά ή ενδο-εταιρικά σας projects. Πληροφορίες και για τα δυο licenses εδω . Παρόλο που η Community έκδοση είναι πλήρως λειτουργική, υπάρχουν πράγματα που παρέχονται μόνο στην Pro όπως για παράδειγμα το localization του Calendar component (στην Community είναι μόνο στα Αγγλικά). Τεχνικά το Ext.NET είναι ένα wrapper framework γύρω από την βιβλιοθήκη JavaScript Ext JS . Η ενσωμάτωση στο Visual Studio και η χρήση στα projects σας είναι απρόσκοπτη και όλα πραγματικά λειτουργούν άψογα εφόσον κάνετε την απλούστατη δήλωση: <%@ Register Assembly= "Ext.Net" Namespace= "Ext.Net" TagPrefix= "ext" %> Η εργαλειοθήκη περιλαμβάνει πάνω από 100 components (όχι και άσχημα, έτσι;...

According to a poll at Framework Programme Sevent (FP7) group on LinkedIn, Horizon 2020 (http://ec.europa.eu/research/horizon2020) may include a cost model change to cover 100% of all direct costs, but limit the overhead rate to a flat 20%. From my perspective this is a change for the better: • now some research organizations’ bureaucratic mechanisms [...]...
