  • Important additions to the Silverlight MaskedTextBox

    RadMaskedTextBox is one of the major controls in the Telerik Silverlight suite. It enables you to filter the user input and makes the work with data much more easier for the end-user. That is why in the past quarter (Q1) we put a great effort and get all the scenarios and users reports that we had so far and made this control as stable as possible. Now post Q1 we added some small, but important new features to the control. Here they are: Option to get the changed value when the focus of the control is lost. Before this change each user stroke causes the ValueChanged and ValueChanging events to be raised. Now you have to option to get these events on lost focus. This also gives you the option to enable the Regular expression validation of the new value on ValueChanging event. So if you want a complex ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Why do you hate Java? Is it the language or the framework? [closed]

    - by zneak
    According to you all, Java is the third most-hated language here. The two other most hated languages are PHP and VBScript. (It's quite funny how they stand together on the podium.) I'd like to make it known that the question mostly addresses people who don't like Java. I assume here a number of subjective opinions as facts because they're usually considered true among people who don't like Java, and I don't want to be convinced otherwise here. If you're a Java enthusiast, you might find this question frustrating. It's never been made clear if people hate Java itself, or if they hate it because of the framework, or if it's a mixture of the two. On a side you have the language, where you have: the "everything should be an object" philosophy, even in instances where it should obviously be something else (event handlers I'm pointing you); checked exceptions; the idea that all logic should be presented as methods and properties is a big no-no; the fact that "closures" created by anonymous types only include final variables and arguments, but will allow write access to any member of the parent class; a few more. On the other side, you have the JDK, with... its load of inconsistencies and overengineering; monolithic class hierarchies; meaningless base exceptions like IOException (though other frameworks have similar exception hierarchies); sluggish responsiveness even with Swing; a few more. My question is, do you think that, if either one (Java or the JDK) was taken alone, and the other was dropped in favor of something else, the new combination would be better? For instance, if you could use the C# syntax with the JDK (adapting get*/set* methods into properties, and interfaces with only one method into delegates), or the Java syntax with the .NET Framework (doing the inverse transformations), would things get better in your opinion?

  • Researching runtime technologies (Xmas fun with HTML5)

    - by Eric Nelson
    The Internet Explorer 9.0 team just posted about Pirates love Daises. This is a showcase game for the power of HTML 5 running inside IE 9.0 – and the author has done a fantastic job (you can get more details from Grant’s blog post). A game developer is an ISV (Independent Software Vendor) – a B2C  ISV. In my role I don’t (typically) work with B2C ISVs, hence a reasonable question is “Why blog about it?”. I think applications like this demonstrate the power of HTML 5 and IE9 for delivering really rich user experiences which have the promise of working cross browser and cross platform - in the future as HTML5 capable browsers become the norm. Microsoft is investing heavily in implementing a great “run time” in IE9 if cross platform is an important requirement for your UX. And the other reason for blogging this… it is nearly Xmas and we all should be having a little more fun on the run in. Hence you can play with confidence that your defence to your manager is “I’m just researching a powerful runtime that Microsoft is working on which could be significant to our future B2B product directions” Play now (Needs HTML 5 browser such as IE9) Related Links: To install IE9 Beta or the Preview (which won’t replace your existing IE) check our the IE9 TestDrive center. Learn about our other important UX runtime with the on-demand recordings of the Silverlight FireStarter event.

  • Windows Server 2003 Standby/Sleep Results in Cold Boot when Resuming

    - by Simon Chadwick
    I'm running Windows Server 2003 sp2 on a Dell Inspiron e1705. There has never been a problem going to standby/sleep mode (by closing the laptop lid, or from the Start menu), and then resuming later. Today I did a Windows Update to install the latest patches and fixes. I don't know if there is a correlation, but now when I resume from standby/sleep mode, the machine does a cold boot. The AC adapter is connected. The battery is 2 months old, and all its LEDs light up when pressing its test button. The Power Management shows it at "99% (charging)" all the time. There is nothing suspicious in any of the event logs. Any ideas?

  • How to explain pointers to a Java/VB programmer

    - by Skeith
    I am writing a game and my friend has offered to help me as it is a RPG and will take a long time to do the "scripting" bit of the game. The problem is IMO he's not that good a programmer :( (add flame war here). He has only programmed in Java and VB and keeps saying really stupid things to me like "Why don't you drag and drop an onClick event" to design my UI when I'm using DirectX. I tried explaining pointers to him but his response was, if it's just a variable that holds a memory address, why don't you just use an int? I create an instance of an attack class and give the creature a pointer to it so if several creatures use the same attack there is only one instance of it. He keeps saying why not put if statements in the creature class for every attack class and set true for the ones that are there. He has programmed mainly in VB and a little in Java just to learn OOP. How can I explain advanced C++ concepts like pointers and memory management to him? He just doesn't understand there are no super functions like form.show in C++.

  • Project collision shapes to plane for 2.5D collision detection

    - by Jkh2
    I am working on a top down 2.5D game. In the game anything that overlaps on the screen should be 'colliding' with each other regardless of whether they are on the same plane in the 3D world. This is illustrated below from a side-ways view: The orange and green circles are spheres floating in the 3D world. They are projected onto a plane parallel to the viewport plane (y = 0 in the image) and if they overlap there is a collision event between them. These spheres are attached to other meshes to represent the sphere bounding boxes for collisions. The way I plan to implement this at the moment is the following: Get the 3D world position at the center of the sphere. Use Camera.WorldToViewportPoint to project the point to the viewport plane. Move a Sphere Collider with the radius of the sphere to that point. Test for collisions using unity colliders. My question is how to extend this to work for rotated cuboids. For instance if I have two rotated cuboids, if I follow the logic above it would not work as intended as the cuboids may not collide but they could still be intersected on the view plane. An example is below: Is there a way to project a cuboid that would be aligned with the plane? Would it be a valid cuboid for all rotations if I did this?

  • Windows Live Writer fails to start

    - by Albert Bori
    I installed windows live writer and configured it to connect to my xmlrpc enabled blog engine. After doing so, it threw an unrecoverable error and closed down. After attempting to restart windows live writer, it throws the following exception each time: Description: Windows Live Writer has encountered a problem: Invalid URI: The hostname could not be parsed. Problem signature: Problem Event Name: WindowsLiveWriter Problem Signature 01: CreateThis Problem Signature 02: 115 Problem Signature 03: System.UriFormatException Problem Signature 04: 15.4.3555.308 Problem Signature 05: 2.0.50727.5456 Problem Signature 06: Windows Live Writer OS Version: 6.1.7601.2.1.0.256.1 Locale ID: 1033 Since I was unable to start windows live writer at all, I tried uninstalling it and removing all files associated with it in my "C:/users/[username]/appdata" folder. After that, I re-installed it and still get the error every time I try to launch the application. Does anyone know how I can get around this?

  • How to Reach German Developers: dotnet Cologne 2011

    - by WeigeltRo
    If you want to promote tools, technologies, libraries, trainings or anything else of interest to software developers, you want to reach the right audience. Not the 9-to-5 people, but those who have the knowledge and passion that make them important multipliers. A great way to reach these people are community conferences. They are not the kind of conference that the 9-to-5 folks are “sent to” by their company, but that the right people hear of via Twitter, Facebook, blogs or plain old word-of-mouth and choose to go to, often covering the costs for the day themselves (travel, entrance fee, hotel, taking the day off). If you want to reach German developers there is one conference that has emerged as the large .NET community conference in Germany, quickly growing beyond being just a local event: The dotnet Cologne, that will be held for the third time on May 6, 2011 and that I’m co-organizing (this interview gives you a good idea of the history). This year’s dotnet Cologne 2010 with its 300 attendees was a huge success. As in the year before, the conference was sold out weeks in advance, and feedback by attendees and sponsors was positive throughout. And the list of speakers and attendees sounded like a “who is who” of the German .NET community. Whether you‘d like to present a product, a service or your company: you will meet the right target audience at dotnet Cologne. We’re offering a broad variety of sponsorship opportunities, ranging from being a donor for the large raffle at the end of the day (software licenses, books, training vouchers, etc.) up to having a booth and/or giving a sponsored talk about your product (not necessarily in German, English is not a problem). Among the various sponsorship levels (bronze/silver/gold/platinum) there’s most likely a package that will suit your needs – and if not, we’re open for suggestions. We’re happy to announce that already at this point in time (with over five months to go) we have a steadily growing list of partners: Microsoft, Intel, IDesign, SubMain, Comma Soft AG, GFU Köln, and EC Software. If you want to become a sponsor for the dotnet Cologne 2011, drop me a line at Roland.Weigelt at dotnet-koelnbonn.de and I’ll send you our sponsor info.

  • Open source clone for Starcraft

    - by sinekonata
    Two questions about a SC:Broodwar clone. Is there one yet? How likely is legal pursuit? Since almost all games I usually play now have an FOS alternative from alpha to way polished, I was wondering why can't I find one for SC, one of the biggest titans of the gaming community? So my first question is, is there a game that was made with the intention to emulate SC? Is it that I didn't look well enough? Could it really be that no one tackled what seems like a small effort compared to the creation of a game engine like Spring or games like Rigs of Rod or Minetest? And since SC is not being maintained at all shouldn't the incentive to see a bug free modable balanced version huge? What am I not getting here? In the event that there is none, is it a legal problem? Could it be that people expect Blizzard to release sources themselves? Or that developers don't see the point in having SC mechanics without the patented lore and aesthetics? And the trickier question, if I were to make SC an open source game, a total clone of it for the purposes of maintenance, modability, etc. Would Blizzard really sue a team of developer fans that just do them a favour knowing they don't lose any money from Korea broadcasts? Or would they do it not to set precedents. So thanks for reading all that, hope I'm not the only one to think it's weird that no one talks about it. See you.

  • Monitoring bespoke software with Zenoss

    - by Andy S
    We've got a lot of back-end applications that we need to monitor the performance of (metrics such as orders waiting to be processed, time since last run, etc). Currently, this is done by an in-house watchdog application that fires out emails whenever a threshold is exceeded, but there's no way to acknowledge an issue and squelch these alerts. Rather than build our own complete alerting system, we'd like to tie in to the Zenoss installation we use to monitor our servers. I've found a few articles on creating events programmatically, but I'd rather Zenoss itself monitors the values that the current watchdog app is looking at (so we get the benefits of graphing and history as well). Is it possible, then, to programmatically provide a data feed (rather than an event) to Zenoss? Or is there another way to go about this?

  • Fedora14 serial console how-to needed

    - by lamba2
    Has anyone ever got a serial console working in fedora 14 ? Is it as simple as adding to grub: serial --unit=0 --speed=38400 terminal --timeout=10 serial console and add to the kernel lines: console=tty0 console=ttyS0,38400 ??? If so, this isn't working for me. I have agetty installed, and im using minicom, although i've heard you can also use "screen /dev/ttyUSB0" on the client side. The /etc/init/serial.conf file suggests it should be working, but nothing. Currently getting no joy from any of this after 2 days. Does anyone know a method that definitely works on fedora 14 ? (no /etc/event.d/ needed or such) edit: Client side im using a null modem cable and usb-serial adaptor.

  • Validar Textbox para aceptar solo n&uacute;meros

    - by Jason Ulloa
    Una de las necesidades más habituales en el desarrollo es poder validar los controles Textbox para que solo acepten valore numéricos. En este post eso es lo que haremos, nos apoyaremos en el lenguaje javascript para validar nuestro textbox del lado del cliente. Nuestro primer paso será crear la función JavaScript que hará el trabajo, para ello agregamos las etiquetas de javascript <script type="text/javascript"> </script> Posteriormente dentro de esas etiquetas agregaremos el script que hará el trabajo function ValidNum(e) { var tecla= document.all ? tecla = e.keyCode : tecla = e.which; return ((tecla > 47 && tecla < 58) || tecla == 46); } Por último iremos al code behind de la página y en el evento Load agregaremos un nuevo evento al textbox para que reconozca el script. protected void Page_Load(object sender, EventArgs e) { TextBox1.Attributes.Add("onkeypress", "javascript:return ValidNum(event);"); } Con esto, tenemos el textbox validado para aceptar solo números y el punto.

  • PC On/Off Time Charts Windows Uptime; No Logging Necessary

    - by Jason Fitzpatrick
    Windows: PC On/Off Time is a graphical tool that displays your PC’s uptime, downtime, errors, and more all in a clear and portable package. One of the hassles of using logging tools is that you usually have to enable the logging and then wait for results to pile up before seeing anything useful (such as when you turn on the logging on your router). PC On/Off Time taps right into the event logs your Windows PC is already keeping so you get immediate access to your uptime history. If you look at the screenshot above you can see an accurate picture of the last few weeks of uptime on my computer. October 23-24 I didn’t boot down my PC, the rest of the time I hibernated it overnight when I wasn’t using it, November 1st I installed an SSD (you can see the burst of reboots and short uptimes) and then November 9th there was a brief power outage that caused an unexpected stop (the red arrows on the timeline for the 9th). The free version offers a three-week peek back into your uptime history (upgrade to the Pro version for $12.75 or for free using Trial Pay to unlock your completely uptime history).PC On/Off Time is Windows only.

  • Is there a design pattern for chained observers?

    - by sharakan
    Several times, I've found myself in a situation where I want to add functionality to an existing Observer-Observable relationship. For example, let's say I have an Observable class called PriceFeed, instances of which are created by a variety of PriceSources. Observers on this are notified whenever the underlying PriceSource updates the PriceFeed with a new price. Now I want to add a feature that allows a (temporary) override to be set on the PriceFeed. The PriceSource should still update prices on the PriceFeed, but for as long as the override is set, whenever a consumer asks PriceFeed for it's current value, it should get the override. The way I did this was to introduce a new OverrideablePriceFeed that is itself both an Observer and an Observable, and that decorates the actual PriceFeed. It's implementation of .getPrice() is straight from Chain of Responsibility, but how about the handling of Observable events? When an override is set or cleared, it should issue it's own event to Observers, as well as forwarding events from the underlying PriceFeed. I think of this as some kind of a chained observer, and was curious if there's a more definitive description of a similar pattern.

  • Macro to manage sport ranking and calendar?

    - by Ale
    I need to write a macro to manage ranking and calendar for curling turnament. The event will follow the Shenkel system first match determined by general draw after that every team has played one match is possible to determine the first ranking second match determined by the rule: 1st vs. 2nd - 3rd vs. 4th - 5th vs. 6th and so on after that every team has played two matches is possible to determine the second ranking and so on until the end (3 to 5 matches normally). Another rule is that from the second match is not possible to play against a team that I played before! I was thinking to use MS-excel but also Calc (both LibreOffice/OpenOffice) should be fine. Thanks in advanced

  • "A device attached to the system is not functioning" when reconnecting to XenApp 6 session

  • Recurring events repeatedly saves a draft every minute

    - by Henrik Rasmussen
    Using Outlook 2010, some of my recurring (planned, not drafts) events is saving a draft to my Drafts folder every single minute as long as it's active. An example taken from real life is that I have a calendar entry (Appointment) occuring every day from 24-09-2012 until 28-09-2012 from 08:00 to 16:00 (GMT+1) with a blue category, only one participant (me) with subject but without a place. So every minute from 24-09-2012 until 28-09-2012 from 08:00 to 16:00, but not from 16:00 to 08:00, a new draft is automatically saved in my Drafts folder. How do I get rid of that behaviour? Addition here: Removing the offending event just allows a new one to take its place. There doesn't seem to be much on the sites - Microsoft calls it a "personal" issue, but there are more and more instances.

  • Scientists Demonstrate First-Person Shooter Games Improve Vision

    - by Jason Fitzpatrick
    Need an excuse to log a few more hours playing Call of Duty or Medal of Honor? Scientists demonstrated improved vision in test subjects after daily doses of first-person shooter games. Scientists at McMaster University took subjects who, as the result of surgery correcting congenital cataracts, had less than 20/20 vision. Subjects played Medal of Honor for a total of 40 hours over the course of 4 weeks before having their vision retested. The results? The CBC reports: The participants found improvements in detail, perception of motion and in low contrast settings. In essence, players could now read about one to one-and-a-half more lines on an optometrist’s eye chart. “We were thrilled,” Lewis said. “It’s very exciting to open up a new world of hope for these people.” How to Get Pro Features in Windows Home Versions with Third Party Tools HTG Explains: Is ReadyBoost Worth Using?

  • How&rsquo;s your Momma an&rsquo; them?

    - by Bill Jones Jr.
    When a Southern “boy” like me sees somebody that used to be, or should be, a close friend or relative that they haven’t seen in a long time, that’s a typical greeting.  Come to think of it, we were often related to close friends. So “back in the day”, we not only knew people but everybody close to them.  When I started driving, my Dad told me to always drive carefully in Polk county.  He said if I ran into anybody there, it was likely they would be related or close family friends. Not so much any more… the cities have gotten bigger and more people come south and stay.  One of the curses of air conditioning I guess. Anyway, it’s been a while.  So “How’s your Momma and them”?  Have you been waiting for me to blog again?  Too bad, I’m back anyway <smile>. Here in Charlotte we just had another great code camp.  The Enterprise Developers Guild is going strong, thanks to the help of a lot of dedicated people.  Mark Wilson, Brian Gough, Syl Walker, Ghayth Hilal, Alberto Botero, Dan Thyer, Jean Doiron, Matt Duffield all come to mind.  Plus all the regulars who volunteer for every special event we have. Brian Gough put on a successful SharePoint Saturday.  Rafael Salas and our friends at the local Pass SQL group had a great SQL Saturday.  Brian Hitney and Glen Gordon keep on doing their usual great job for developers in the southeast as our local Microsoft reps. Since my last post, I have the honor of being designated the INetA Membership Mentor for Georgia in addition to mentoring the groups in the Carolinas for the past several years.  Georgia could be a really good thing since my wife likes shopping in Atlanta, not to mention how much we both like Georgia in general.  As I recall, my Momma had people in Georgia.  Wonder how their “Mommas an’ them” are doing?   Bill J

  • Is it bad practice for services to share a database in SOA?

    - by Paul T Davies
    I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?
