• How to determine JAVA_HOME on Debian/Ubuntu?

  - by Witek

  On Ubuntu it is possible to have multiple JVMs at the same time. The default one is selected with update-alternatives. But this does not set the JAVA_HOME environment variable, due to a debian policy. I am writing a launcher script (bash), which starts a java application. This java application needs the JAVA_HOME environment variable. So how to get the path of the JVM which is currently selected by update-alternatives?

• NTLM Authentication fails ONLY with IE against 2k8 App server behind 2k8 IIS7 Reverse Proxy

  - by CptSkippy

  I'm developing an ASP.NET application for an intranet site that is using Windows/NTLM/WIA/whatever authentication. The application is hosted on a Windows 2k8 server but is accessed through a Reverse Proxy using IIs7 on another 2k8 machine. Authentication works fine in FireFox, Chrome and Safari but fails in IE8. If I circumvent the Proxy and access the application server directly then it works fine so it has something to do with proxy. There's nothing in the Event Viewer on any of the 3 machines to indicate what might be happening. If you connect using IE8 it prompts for your credentials instead of automatically passing them, yes I've setup an explicit trust over an above the domain trust, but it still errors out with a 401 error returned from the proxy. Any ideas where to start troubleshooting this?

  In my application, I am trying to play a sound file in ogg format, stored in raw folder in res directory of my application.

What am I doing wrong? private void playbeep() { mPlayer = MediaPlayer.create(this, R.raw.beep); mPlayer.start(); mPlayer.release(); }

• How to disable Skype from using system tray (notification area) on Linux?

  - by Ivan

  I use AWN dock on Linux (which behaves much like Windows 7 panes, using one icon for launching an application and managing its windows). It loses Skype (as well as any other application) when it goes minimized to system tray (notification area). Can I disable Skype from minimizing to system tray favouring Win7-like behaviour? Skype version I use is 2.1 beta, but I would not mind reinstalling it in favour of another version. I use Arch Linux with all the latest kernel, x.org and xfce.

• Simplest way to extend doctrine for MVC Models

  - by RobertPitt

  Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

• Moving from WCF RIA RC to Release: best practices?

  - by Duncan Bayne

  I have an existing WCF RIA project built on the Release Candidate; I'm now moving to the Release version & have discovered many changes. David Scruggs made the following comment on his (MSDN) blog: "If you’ve written anything in SIlverlight 4 RIA Services, you’ll need to rewrite it. There has been a lot of refactoring and namespace moves." Having made a brief attempt to compile the old solution with the new RIA framework I'm inclined to agree. My current plan is to: remove the Silverlight Business Application projects from the Solution rebuild the EF4 items from the database create a new Silverlight Business Application project re-add the files (XAML, CS) from the old Silverlight Business Application project Does this sound like a reasonable approach? I think it's cleaner than trying to manually alter the existing project.

• Missing DLL Problem

  - by Liran

  Hi everyone. I have a C++ native application that was built under VS2005 (sp1),On machine A. (Debug Mode) Now,I need to run this application on a "clean" computer, Clean means it has no VS installed on. When i copy the runtime folder from machine A to the "clean" machine and try to activate the application it demands to reinstall the application. obviously missing DLLs are causing this problem cause on machine A the app works just fine, Is there any "clean" solution for this kind of problem besides gessing which DLLs are missing ? maybe a smart tool or installer that indicates which DLLs are missing at the runtime ? Thanks, Liran

• How to avoid Modal Storyboard infinite loop

  - by misthills

  I've written a number of iOS applications a year ago on an old version of Xcode. I've just started a new project and discovered the storyboard feature in the latest Xcode. It turns out this is perfect for the application I am writing as it consists of ~30 interlinked screens. My question is, how do I structure my storyboard and segues to allow my application to follow a circular path through my screens. I have seen a number of examples that simply segue screen 1 to screen 2 and then screen 2 to screen 1 using the modal option. This clearly works but when I debug an application built this way, it instantiates a new instance of each screen (view controller) for every segue performed. In the diagram below (apologies, I drew a nice picture but due to my newbie status, was not able to post it), how do I go from screen 1 to screen 2 to screen 3 and back to original screen 1 without creating a new instance? // Screen 1 --> Screen 2 --> Screen3 // ^ | // | | // +-------------------------+

• Visual Studio: Link executable

  - by smerlin

  Lets say I have: a static library project called "LIB" a application project called "LIBAPP" a application project called "APP" a application project called "APPTEST" When i add "LIB" to LIBAPP Project Dependencies, Visual Studio automatically links "LIBAPP" against LIB. But when i add APP to APPTEST Project Dependencies, it doesnt. Since i am doing unit tests of APP's classes in APPTEST, i have to link against APP, therefore i am currently manually linking against all *.obj files of APP (hundreds...) Since i have to change the link targets of APPTEST everytime i add or remove a *.cpp file from APP, this isnt a nice solution. So is there a way to force Visual Studio to do this for me automatically, like it does when adding a static library Project Dependency ?

• How to handle server-client requests

  - by Layne

  Currently I'm working on a Server-Client system which will be the backbone of my application. I have to find the best way to send requests and handle them on the server-side. The server-side should be able to handle requests like this one: getPortfolio -i 2 -d all In an old project I decided to send such a request as string and the server application had to look up the first part of the string ("getPortfolio"). Afterwards the server application had to find the correct method in a map which linked the methods with the the first part of the string ("getPortfolio"). The second part ("-i 2 -d all") got passed as parameter and the method itself had to handle this string/parameter. I doubt that this is the best solution in order to handle many different requests.

• Why does System.Threading.Timer callback successfully update UI?

  - by Geo P

  I have several System.Threading.Timers on my form application with callbacks that update the UI...successfully - i.e. without throwing errors. I had built these earlier, before I knew that UI should not be updated on any thread other than the UI thread. Now I am confused as to why it does not throw cross-thread exceptions when I am updating UI on these separate threading.timer threads? I will be changing these callbacks so that the UI updates are invoked on UI thread, but I am curious as to why this works. Edit: My application is a WinForms Application.

• access models and forms within modules

  - by sims

  Hi Stackers, What is the best way to access my models and forms from a controller of a module? Let's explain with "pictures": /application/module/storage/controllers/IndexController.php needs to call readAction in the class called storage_Model_Files in /application/module/storage/models/Files.php I've made this app's dir structure and these forms and models with zf.sh (Zend_Tool). I've read about all sorts of ways of manually including these files. I want to lazy load them much like everything is done automatically with the default module. I can't seem to find how in the docs. Does that make sense? I have: resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" in my application.ini file. So I can access my controllers fine. Thanks for your help!

• Can I get information about the IIS7 virtual directory from Application_Start?

  - by Keith

  I have 3 IIS7 virtual directories which point to the same physical directory. Each one has a unique host headers bound to it and each one runs in its own app pool. Ultimately, 3 instances of the same ASP.NET application. In the Application_Start event handler of global.asax I would like to identify which instance of the application is running (to conditionally execute some code). Since the Request object is not available, I cannot interrogate the current URL so I would like to interrogate the binding information of the current virtual directory? Since the host header binding is unique for each site, it would allow me to identify which application instance is starting up. Does anyone know how to do this or have a better suggestion?

• How to configure Spring-DM OSGi service for new instance per call?

  - by Bhav

  I'm starting to delve into using Spring DM and OSGi services in an RCP application. I've created a service which is used by another bundle in the RCP application. It does a lookup of the service via calls to getBundleContext().getServiceReference() using the explicit bundle names and service class names. I'm not using DI anywhere yet. The issue I'm running into is that the service that is returned in the requesting bundle is a singleton. At times I notice a threading issue since it is a "stateful" service. How do I configure the application to get back a new service instance with each call? Here is my spring xml file contents which registers the service: <bean id="myServBean" class="com.xyz.ClassImpl"/> <osgi:service ref="myServBean" class="com.xyz.Class"/>

• Mixing .NET 3.5 with 4/4.5 assemblies in the same process

  - by lysergic-acid

  Our team builds a .NET 3.5 WinForms based application that we'd like to migrate to the latest .NET version (4.5). Our application uses many "external" components (can be thought of as plugins) that are also currently .NET 3.5 based. I'd like to know what runtime/core libraries are used in case we convert ONLY THE APPLICATION to compile using .NET 4.5? Should this scenario properly work? (loading .NET 3.5 assemblies in a 4.5 process)? * The plugin assemblies are loaded via reflection. How does the CLR runtime handle such a scenario? is this a safe practice?

• Integrate ClickOnce update in a setup

  - by Erick

  As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).
