  • I'd like to learn how to do mobile development - which competitions can I join to help me learn?

    - by Oscar
    I want to start learning mobile device development, but I am someone that gets much more motivated when there is some goal to reach. Because of that, I would like to join a competition. I know about Microsoft Imagine Cup, which is a very nice competition. Are there any another mobile development competition with a deadline in the next 6~8 months? I have been googling for them, but I could not find any, maybe someone knows about something that I couldn't find.

  • Visual Studio 2010 RC &ndash; Silverlight 4 and WCF RIA Services Development - Updates from MIX Anno

    - by Harish Ranganathan
    MIX is happening and there is a lot of excitement around the various releases such as the Windows Phone 7 Developer Preview, IE9 Platform Preview and few other announcements that have been made.  Clearly, the Windows Phone 7 Developer Preview has generated the maximum interest and opened a plethora of opportunities for .NET Developers.  It also takes the mobile development to a new generation and doesn’t force developers to learn different programming language. Along with this, few other releases have been out.  The most anticipated Silverlight 4 RC is out and its corresponding templates are also out there for you to download.  Once VS 2010 RC was released, it was much of a disappointment that it doesn’t support SL4 development as well as the SL4 Business Application Development (a.k.a. WCF RIA Services).   There were few workarounds though nothing concrete.  Earlier I had written about how the WCF RIA Services Preview does work with ASP.NET Development using VS 2010 RC. However, with the release of SL4 RC and the corresponding tooling updates, one can develop for both SL4 as well as SL4 + WCF RIA Services using VS 2010 RC.  This is kind of important and keeps the continuum going until VS 2010 RTMs.  So, the purpose of this post is to quickly give the updates and links to install the relevant tools. Silverlight 4 RC Runtime Windows Runtime or the Mac Runtime Silverlight 4 RC Developer Tools for Visual Studio 2010 RC Silverlight 4 Tools for Visual Studio 2010 (this would install the Runtime as well automatically) Expression Blend 4 Beta Expression Blend 4 Beta If you install the SL4 RC Developer Tools, it also installs the WCF RIA Services Preview automatically.  You just need to install the WCF RIA Services Toolkit that can be downloaded from Install the WCF RIA Services Toolkit Of course you can also just install the WCF RIA Services for VS 2010 RC separately (without SL4 Tools) from here Kindly note, all the above mentioned links are with respect to Visual Studio 2010 RC edition.  If you are developing with VS 2008, then you can just target SL3 (as I write this, there seems to be no official support for developing SL4 with VS 2008) and the related tools can be downloaded from http://www.silverlight.net/getstarted/ Basically you need to download SL 3 Runtime, SDK, Expression Blend 3 and the Silverlight Toolkit.  All the links for the download are available in the above mentioned page. Also, a version of WCF RIA Services that is supported in VS 2008 is available for download at WCF RIA Services Beta for VS 2008 I know there are far too many things to keep in mind.  So, I put a flowchart that could help with depicting it pictorial.  Note that this is just my own imagination and doesn’t cover all scenarios.  for example, if you are neither developing for Webform, Silverlight, you end up nowhere whereas in actual scenario you may want to develop Desktop, Services, Console, Game and what not.  So, keep in mind this is just Web. Cheers !!!

  • Can anybody recommend C#/XAML Windows Store Development aggregator sites?

    - by Clay Shannon
    I used to have a couple of sites bookmarked that were Windows development article/blog post aggregators. I can't recall what they were called. What I want to do now is to keep up with all relevant C#/XAML "Windows Store" app development info, whether it be blog posts, new "Metro"-specific channel 9 videos, etc., without spending lots of time surfing about. Can anybody recommend any "C#/XAML Windows Store new information aggregators"?

    - by chossen-addict
    I'm in the final year of my Computer Science degree, and I'm starting to look at what I can work on as a final-year project. I've been looking at creating a Kinect application, but I'm not sure if I have the necessary background to get involved in its development. What should I know before starting Kinect development? Are there areas of programming I should have a background in in order to understand what I need to do to create a Kinect app?

  • Where can I find some software development freelance/contract positions? [closed]

    - by m-y
    I currently have a full time job as a Microsoft.NET developer, but I'd like to supplement my income by doing some part-time freelance development work. Are there any websites (or other sources) out there that specialize in this? While the website (or other source) does not have to be geared specifically for part-time work or Microsoft.NET development, if it is than that would be just wonderful. The only thing I could find close to this was www.vworker.com which is not that great.

  • JAMES Mailet development process

    - by itsadok
    I'm starting a project that involves writing mailets for Apache James. As far as I can tell, the only way to test a change in my code (on Windows) is through the following steps: Compile the mailet code Build a jar file containing the mailet Copy the jar file into the apps/james/SAR-INF/lib directory Start JAMES from run.bat Run test Stop JAMES by telneting to port 4555 and issuing a shutdown command (I guess on Linux a SIGTERM would suffice) I can automate all these steps using Ant and some scripting magic, but I was wondering if I was missing something. Does anyone here have experience developing mailets? Did you use a similar process, or is there an easier way? For example, is there a way to make a running James instance reload the mailets JAR?

  • image filters for iphone sdk development

    - by plsp
    Hi All, I am planning to develop an iphone app which makes use of image filters like blurring, sharpening,etc. I noticed that there are few approaches for this one, Use openGL ES. I even found an example code on apple iphone dev site. How easy is openGL for somebody who has never used it? Can the image filters be implemented using the openGL framework? There is a Quartz demo as well posted on apple iphone dev site. Has anybody used this framework for doing image processing? How is this approach compared to openGL framework? Don't use openGL and Quartz framework. Basically access the raw pixels from the image and do the manipulation myself. Make use of any custom built image processing libraries like this one. Do you know of any other libraries like this one? Can anybody provide insights/suggestions on which option is the best? Your opinions are highly appreciated. Thanks!

  • Facebook Game Development - Which Programming languages?

    - by Ben
    Hi folks, I am going to develop a facebook game as topic for my thesis. I am wondering which programming languages i should choice. I am used to programming in .NET. But i am also comfortable in C++ and Java. I don't want to use Flash as the graphical frontend since i don't like it. So i guess i'll go with ASP.NET + Silverlight. What do you think?

  • iPhone Development with Bluetooth SPP OS 3/4

    - by nigel-jewell
    Hi all, I am in the process of developing an iPhone application that communicates with a number of Bluetooth devices that all support Serial Port Profile - well I assume that it is SPP as they show on my MacBook as Serial Port DevB etc. I understand that iPhone OS 3.x does not support SPP - is that correct? Does anyone know if that has been "fixed" in OS 4? I've seen reports of OS 4 supporting keyboards, but is that a locked version of HID, or will SPP be available via the SDK? Kind Regards, Nige.

  • Exception seem in an eclipse GMF application when file not present in workspace

    - by rush00121
    I am developing a GMF application . In this situation , I start my workspace and load a file in the workspace . Then I close the workspace and then delete the file from the workspace . After that, I try to restart my application and restore the workspace . Of course , now since the file does not exist , there are going to be exceptions . I tried a lot to handle these exceptions but if I try to get rid of one exception , then another pops up . Does anyone know what methods do I have to override in order to handle this situation correctly . I am attaching the stacktrace that I get in this exception for a better picture . org.eclipse.core.runtime.CoreException: ERROR at org.eclipse.gmf.runtime.diagram.ui.resources.edito r.parts.DiagramDocumentEditor.createPartControl(Di agramDocumentEditor.java:1509) at com.fnfr.itest.topology.tbml.diagram.custom.part.S ingleFileTbmlDiagramEditor.createPartControl(Singl eFileTbmlDiagramEditor.java:120) at org.eclipse.ui.internal.EditorReference.createPart Helper(EditorReference.java:662) at org.eclipse.ui.internal.EditorReference.createPart (EditorReference.java:462) at org.eclipse.ui.internal.WorkbenchPartReference.get Part(WorkbenchPartReference.java:595) at org.eclipse.ui.internal.EditorAreaHelper.setVisibl eEditor(EditorAreaHelper.java:271) at org.eclipse.ui.internal.EditorManager.setVisibleEd itor(EditorManager.java:1417) at org.eclipse.ui.internal.EditorManager$5.runWithExc eption(EditorManager.java:942) at org.eclipse.ui.internal.StartupThreading$StartupRu nnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableL ock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessa ges(Synchronizer.java:134) at org.eclipse.swt.widgets.Display.runAsyncMessages(D isplay.java:3855) at org.eclipse.swt.widgets.Display.readAndDispatch(Di splay.java:3476) at org.eclipse.ui.application.WorkbenchAdvisor.openWi ndows(WorkbenchAdvisor.java:803) at org.eclipse.ui.internal.Workbench$28.runWithExcept ion(Workbench.java:1384) at org.eclipse.ui.internal.StartupThreading$StartupRu nnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableL ock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessa ges(Synchronizer.java:134) at org.eclipse.swt.widgets.Display.runAsyncMessages(D isplay.java:3855) at org.eclipse.swt.widgets.Display.readAndDispatch(Di splay.java:3476) at org.eclipse.ui.internal.Workbench.runUI(Workbench. java:2316) at org.eclipse.ui.internal.Workbench.access$4(Workben ch.java:2221) at org.eclipse.ui.internal.Workbench$5.run(Workbench. java:500) at org.eclipse.core.databinding.observable.Realm.runW ithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWork bench(Workbench.java:493) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(Pl atformUI.java:149) at com.fnfr.svt.rcp.Application.runWorkbench(Applicat ion.java:205) at com.fnfr.svt.rcp.Application.start(Application.jav a:190) at org.eclipse.equinox.internal.app.EclipseAppHandle. run(EclipseAppHandle.java:194) at org.eclipse.core.runtime.internal.adaptor.EclipseA ppLauncher.runApplication(EclipseAppLauncher.java: 110) at org.eclipse.core.runtime.internal.adaptor.EclipseA ppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.ru n(EclipseStarter.java:368) at org.eclipse.core.runtime.adaptor.EclipseStarter.ru n(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Nativ e Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknow n Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Un known Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework( Main.java:559) at org.eclipse.equinox.launcher.Main.basicRun(Main.ja va:514) at org.eclipse.equinox.launcher.Main.run(Main.java:13 11) Add to rshah's Reputation

  • Installshield Development Error durring the Installation process

    - by Alopekos
    Hey guys, I've been stuck by a problem for the past couple days that makes no sense to me. My installer builds fine in the Installshiled IDE but when it is about to finish the installation, int gets two errors then rollbacks: installation failure. Right when the install bar is at about 100%, an error box pops up that states this: "Error 1001.Exception occurred while initializing the installation: System.IO.FileLoadException: Attempt to load an unverifiable executable with fixups (IAT with more than 2 sections or a TLS section.) (Exception from HRESULT: 0x80131019)." The box pops up once, then the installer flashes its status to "rollback" then pops up another error box, then once 'ok'ed it procedes to rollback as usual. I don't understand that error message so i looked in the msi loggings and found this: "InstallShield 13:20:08: Initializing Property Bag...

For some reason it looks like to me that installshield is trying to launch my program before it finishes the installation, even when I told it to prompt the user to decide to launch. Is this a registering command system that makes it attemp or what? I've been scouring the web all day and I've found some ideas, but I havent seen any solutions as of yet. The installers that I've tried(and failed) have always needed to be Setup.exes, when i try to build a .msi only setup I get this error message. It may help someone who knows more about this system than I do. Your project contains InstallShield prerequisites. A Setup.exe setup launcher is required if you are build a release that includes InstallShield prerequisites. Change your release settings to build Setup.exe, or remove the prerequisites from your project. -7076 There's nothing on the site that has anything from the error code, so I'm at a loss. Thanks for any help possible, I'm an intern and I'm fresh out of ideas... Josh System: XP SP3 Installshield 2010 Pro Install being tested on a VirtualPC

  • Best Non-Microsoft/.NET Development Blogs and Podcasts

    - by Mark Lubin
    I really don't want to rile anyone's feathers and I really enjoy blogs like Joel, Coding Horror, Scott Hanselman, etc. However, what are some good blogs/podcasts that focus on other platforms besides Microsoft based ones or maybe even no particular platform at? In particular I am interested in areas like Python, Ruby, Java, C, but any area besides Microsoft fits the bill. There may be other similar questions to this but I think this one is unique since we might get some answers we wouldn't see otherwise, that is, everyone knows Coding Horror is great. Please try to refrain from religious debates; the content of the blog is more important than the platform they are talking about, I just want to get an idea of what is out there and worth the time.

  • iPhone Development: CoreLocation and MapKit

    - by Mustafa
    How bad is it to use Location Manager to retrieve the location information when MapView.showUserLocation is also TRUE? I have a situation where i want to show the blue dot to indicate the user's current location, and i want to record the user's current location after some time interval. Having said that, there may be situations where the user's current location is now being shown, but i still want to get the user's current location. I think i'll have to use the Location Manager in my controller class, but setting showUserLocation = YES would mean that i'll be draining more battery since two Location Managers are working at the same time? Is this assumption correct?
