• Robotium Uniting Testing on an application having multiple processes

  - by warenix

  I have written an application running activities in multiple processes. I tried Robotium by creating a new test project set target package to my application. When I executed it, the test stopped with the following error message: Error in testDisplayBlackBox: java.lang.RuntimeException: Intent in process com.abc.def resolved to different process com.abc.def:mail: Intent { act=android.intent.action.MAIN flg=0x10000000 cmp=com.abc.def/com.abc.def.email.activity.Welcome } at android.app.Instrumentation.startActivitySync(Instrumentation.java:377) at android.test.InstrumentationTestCase.launchActivityWithIntent(InstrumentationTestCase.java:119) at android.test.InstrumentationTestCase.launchActivity(InstrumentationTestCase.java:97) at android.test.ActivityInstrumentationTestCase2.getActivity(ActivityInstrumentationTestCase2.java:104) at com.abc.def.test.TestApk.setUp(TestApk.java:31) at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:190) at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:175) at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:555) at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1584) Test results for InstrumentationTestRunner=.E Time: 0.027 FAILURES!!!

• fastest (low latency) method for Inter Process Communication between Java and C/C++

  - by Bastien

  Hello, I have a Java app, connecting through TCP socket to a "server" developed in C/C++. both app & server are running on the same machine, a Solaris box (but we're considering migrating to Linux eventually). type of data exchanged is simple messages (login, login ACK, then client asks for something, server replies). each message is around 300 bytes long. Currently we're using Sockets, and all is OK, however I'm looking for a faster way to exchange data (lower latency), using IPC methods. I've been researching the net and came up with references to the following technologies: - shared memory - pipes - queues but I couldn't find proper analysis of their respective performances, neither how to implement them in both JAVA and C/C++ (so that they can talk to each other), except maybe pipes that I could imagine how to do. can anyone comment about performances & feasibility of each method in this context ? any pointer / link to useful implementation information ? thanks for your help

• Rails - how can I query the db w/o touching the sessions table

  - by sa125

  Hi - I'm trying to provide a HTTP api to my app that queries a db that's read-only (for replication purposes). I find that my app crashes repeatedly when making a request b/c the call is trying to update the sessions table whenever I query the db. This doesn't happen when I return some text without hitting the database for info. class APIController < AplicationController def view data = Product.find(params[:id]).to_json # will fail data = { :one => 1, :two => 2 }.to_json # will succeed respond_to do |format| format.html { render :json => data } end end end How do I restrict it from touching the sessions table on this request (it's currently issuing an UPDATE on the updated_at field for that session). thanks.

• How to "host' an application on one mac and run it on another

  - by Fred Jenson

  I recently replaced my mac computer and would like to know if it is possible to run software on that computer that actually runs on another computer. My problem is that I use a terminal emulator that speaks SCO-ANSI on my old computer, but it is not compatible with the new version of OS X. I don't want to pay the exorbitant ($200+) licensing fee to get a current version of the software, so I'd like to know if it's possible to run the emulator on the old computer and just "stream" its window somehow to my new Mac computer. Is this possible? Thanks very much!!!

• MS Office 2007 std, on a 2008R2 RDS session - additional language and proofing tools question

  - by dyasny

  Hi all, I have a terminal server, with a bunch of users running MS Office 2007 std in. Some of them have recently been asking for better multilanguage support. Since I'm in a select agreement, I've gone into the Volume Licensing Service Center and downloaded the following three ISOs: Office Multilanguage Packs 2007 (DVD) Office Multilanguage Packs 2007 (CD) Office Multilanguage Pack 2007 Service Pack 1 But having mounted the ISOs in my RDS host, I still can't install anything they contain. I am quite probably doing something wrong, or maybe I need to be running Office pro version? please F1

• Can I use PLink and Pageant with Cygwin's ssh?

  - by Jerph

  I'm now using msysgit because of the GUI tools, which use Putty's Pageant and PLink utilities, but I use Cygwin as a general SSH terminal. I had been using ssh-agent on Cygwin, but that means I have to enter my SSH key passphrases for both SSH key managers. Is it possible to configure all my Unix-port tools (msys, git, cygwin, Ruby Net:SSH, etc.) to use PLink/Pageant instead of ssh-agent? It seems that's the kind of thing PLink was made for, but I can't find documentation on how.

• Programming a windows service

  - by xarzu

  I have started prgramming a windows service. I have added a notify icon from the toolbox. It has the small notify icon that appears in the systray as a member of those icons. It works so far. So far I have a blank form. I have used the DoubleClick for the notifyIcon to bring up the form (I will use the form for something later). Now I have a list of things I want to accomplish to make this work like a true windows service. First of all, if possible, I owuld like to remove the maximize and cancel button on the form. Most windos service apps that I have seen offer the ability to close the app by right-mouse-button clicking on the notify icon which brings up a menu of options. I see in the properties of the form under Misc there is an CancelButton. But I do not see how do deactivate it. In the Properties of the forum I see under Window Style there is a ControlBox option that, if I turn to false, all three buttons, (minimize, maximize and cancel) go away. These are not what i am looking for. I would not like the option for them to resize, maximize or close the form here. I suspect people will close the box intending to make the box go away while still wanting the app to run. Under the "Focus" caption in Properties, there id "Deactivate". I have created my own event/method/function for this and in debug I noticed that when you click on the x-box in the upper right corner, this function is called. The problem is that after the function is over, the app closes anyway. How do I over-ride this function? Secondly, how do you catch the right button click event on the notify icon in the systray? I can see how to create events for "Click" and "MouseClick" etc. but how so I determine which button was click? Using the right buton click is how such programs know when to pull up a menu. So I would like to know how to do this as well.

• iPhone link to map directions using string "current location" not lat and lng for saddr

  - by Nick

  I know there are numerous questions about how to construct a sharedApplication link to the maps app specifying the start and end address with coordinates. I've got that working no problem. Has anyone found a way to link with a source address generically specified as "current location". I ask because the scenario I'm working on having Core Location or a UIMapView would only be necessary in order to determine the user location prior to handing off to the map app where the user locating would seem to just happen again. I've tried throwing UTF8'd "Current Location" and "[Current Location]" into the saddr parameter which amusingly starts from Current Montana. I've also tried simply excluding the saddr param. I know this is often tread territory but this particular situation wasn't covered by anything I found searching here or on mapki. Before I add the core location code I just wanted to make sure there wasn't a more limited way to tackle this. Thanks

• Understanding the Linux Root

  - by Zac

  I've been using Linux (Ubuntu) for about 2 weeks now and am still struggling with some basic concept surrounding the root user: (1) Some terminal operations (such as making subdirectories inside a FHS directory such as /opt) require me to prefix the command with sudo - why? I guess what I'm choking on is: if I'm already logged in as a valid system user, why do I have to be a superuser/root in order to modify things that the sysadmin has already deemed me worthy of accessing? (2) Is there a GUI (Gnome, KDE) equivalent to sudo? Is there a way to assume a superuser role through a graphical context, rather than from inside a new shell? (3) I can't access the /root directory logged in as myself... but I installed the system to begin with and was never asked to create a root account! How do I log in as root and gain access to /root?!? Thanks for all feedback & input!

• Having trouble getting MEF imports to be resolved

  - by Dave

  This is sort of a continuation of one of my earlier posts, which involves the resolving of modules in my WPF application. This question is specifically related to the effect of interdependencies of modules and the method of constructing those modules (i.e. via MEF or through new) on MEF's ability to resolve relationships. First of all, here is a simple UML diagram of my test application: I have tried two approaches: left approach: the App implements IError right approach: the App has a member that implements IError Left approach My code behind looked like this (just the MEF-related stuff): // app.cs [Export(typeof(IError))] public partial class Window1 : Window, IError { [Import] public CandyCo.Shared.LibraryInterfaces.IPlugin Plugin { get; set; } [Export] public CandyCo.Shared.LibraryInterfaces.ICandySettings Settings { get; set; } private ICandySettings Settings; public Window1() { // I create the preferences here with new, instead of using MEF. I wonder // if that's my whole problem? If I use MEF, and want to have parameters // going to the constructor, then do I have to [Export] a POCO (i.e. string)? Settings = new CandySettings( "Settings", @"c:\settings.xml"); var catalog = new DirectoryCatalog( "."); var container = new CompositionContainer( catalog); try { container.ComposeParts( this); } catch( CompositionException ex) { foreach( CompositionError e in ex.Errors) { string description = e.Description; string details = e.Exception.Message; } throw; } } } // plugin.cs [Export(typeof(IPlugin))] public class Plugin : IPlugin { [Import] public CandyCo.Shared.LibraryInterfaces.ICandySettings CandySettings { get; set; } [Import] public CandyCo.Shared.LibraryInterfaces.IError ErrorInterface { get; set; } [ImportingConstructor] public Plugin( ICandySettings candy_settings, IError error_interface) { CandySettings = candy_settings; ErrorInterface = error_interface; } } // candysettings.cs [Export(typeof(ICandySettings))] public class CandySettings : ICandySettings { ... } Right-side approach Basically the same as the left-side approach, except that I created a class that inherits from IError in the same assembly as Window1. I then used an [Import] to try to get MEF to resolve that for me. Can anyone explain how the two ways I have approached MEF here are flawed? I have been in the dark for so long that instead of reading about MEF and trying different suggestions, I've added MEF to my solution and am stepping into the code. The part where it looks like it fails is when it calls partManager.GetSavedImport(). For some reason, the importCache is null, which I don't understand. All the way up to this point, it's been looking at the part (Window1) and trying to resolve two imported interfaces -- IError and IPlugin. I would have expected it to enter code that looks at other assemblies in the same executable folder, and then check it for exports so that it knows how to resolve the imports...

• Word 2007 cannot open old doc files anymore

  - by nilsi

  Since last week I am unable to open old doc files with Microsoft Word 2007. Whenever I try that I first get a warning about converters being a security issue. (I can disable that in the registry). After accepting (or disabling) this warning, however, I just get the following error message: Unglütiger Datentyp (Word 6.0/95 für Windows & Macintosh which means in English: Invalid document type (Word 6.0/95 for Windows & Macintosh I tried to goolge both the German and the translated error message but did not find anything related. The files in question can be opened by other users for the windows terminal server without problems.

• How to JBoss/Blazeds clustering and channel failover

  - by Francesco

  Hi, I'm stuck with jboss and blazeds clusterization. What I have now is : 2 Jboss Instances, running in all mode One load balancer with apache and mod_jk, as suggested by Jboss docs A spring/flex integration app A flex application that I do not want to throw errors when one of my JBoss instances falls I find Adobe documentation really lacking, and being new at clustering, jgroups and balancing I cannot find how to deploy my app in clustered environment. From what I understood if configured correctly blazeds should tell flex client about failover servers upon connection. Then if flex client can't connect to the main server it goes to another. But the hard part for me is getting there. Can someone point me to the right direction? Thanks in advance

• Ending php sessions for debugging purposes

  - by Bill Zimmerman

  Hi, This might be very easy to do, but I haven't been able to figure it out. Basically, I have a loosely couple web-app written in python and php. The python code uses PHP sessions (generated from the PHP app when the user logs in) to check if the user is logged in/has permission to access the given python resource. My question is this: What is the easiest way to force all active sessions to timeout. I would like to do this for debugging purposes, to test out the python code. I tried changing the session.max_lifetime PHP variable, but that still doesn't guarantee that the session has ended and is removed. I tried just deleting the file, but this seems to cause problems (when i refresh the php page, errors show up in my apache logs and it won't reload quickly) Any ideas?

• Qt4: QMenuBar/QMenu doesn't show up on Mac OS X

  - by Erick

  Hello, I'm having difficulties to make a QMenuBar display a QMenu with a QAction under Mac OS X (Snow Leopard). Here is the code I'm using for creating the menu: void ClientWindow::setUpMenu () { QMenu * file = menuBar()->addMenu("&File"); QAction * quit = new QAction("&Quit", this); file->addAction(quit); connect(quit, SIGNAL(triggered()), this, SLOT(quit())); } Here is the ClientWindow class interface: class ClientWindow : public QMainWindow { public: ClientWindow (QWidget * parent = 0); void setUpMenu (); }; And here is my main() method: int main (int argc, char * argv[]) { QApplication app(argc, argv); ClientWindow window; window.setUpMenu(); window.show(); return app.exec(); } Any ideas why it wouldn't show up on the menu bar? Thank you all.

• Running Mac OS X 10.6 my users home directory is wrong

  - by Erik Miller

  Somehow my home directory on my Mac has been changed and I'm not sure how to go about changing it back, I'm more of a linux guy and Mac OS X has some other mechanism for storing that information. Basically when I log into the machine normally than start a terminal window. I start in the /Users/erik_miller directory, which is my home directory, but when I run some this like cd ~ The machine tries to change to /Users/erik_miller. Yes, the same path with a period on the end. I can change my $HOME environment variable for the session, but the next time I start the machine it reverts. So, I think if I can find where that information is stored I can just change it there and hopefully all will be well.

• How to check a local wifi connection

  hi all, I'm writing an app which connects to a static ip adress in a local network. How can I check if I have a local network connection? I want to connect to http://192.168.2.5 and i tried using the Rechability class but it returns FALSE, while the device is definately connected ( when i don't do the check, the app works fine so there is a connection ): Reachability *r = [Reachability reachabilityWithHostName:@"http://192.168.2.5"]; NetworkStatus internetStatus = [r currentReachabilityStatus]; How should work this out?

• Ubuntu: On-screen keyboard

  - by Paul Lammertsma

  On a similar note to this question, I recently booted Ubuntu to recover a Windows partition, but couldn't in any way get the keyboard to register. I recall back in 8.x that you could easily reach the on-screen keyboard (Virtual Keyboard?) via "Assistive Technologies". It seems to have disappeared since 9.x. For future reference, how can I easily get to it? Recall that in this scenario I won't have a keyboard to enter terminal commands (e.g. to install xkbd or something of the like).

• Free hosting service for private and public git repositories

  - by Alexander

  Hi, does anyone know a free service for hosting private and public git repositories? There are a lot of services like for example the well known github. Most of them only allow hosting of public repositories. I want to host one or more of my private programming projects using git, but not all of them should be public (at least not for now). I also found the free service GitFarm which is build using the Google App Engine technology, but i couldn't find any information how it works (don't know what "built on Google App Engine technology" means) or if there are any other limitations. Also it seams like there is no web front-end available. An integrated web front-end, bug tracker and stuff like this would also be a big plus!

• Frame Redirect in C#

  - by Simon Linder

  I would like to execute a frame redirect in C# from my managed module for the IIS 7. When I call context.Response.Redirect(@"http://www.myRedirect.org");the correct page is shown but also the address is shown in the browser. And that is exactly what I do not want. So I want something like: private void OnBeginRequest(object sender, EventArgs e) { HttpApplication app = (HttpApplication)sender; HttpContext context = app.Context; // make a frame redirect if a specified page is called if (context.Request.ServerVariable["HTTP_REFERER"].Equals(@"http://www.myPage.org/1.html")) { // perform the frame redirect here, but how? // so something like context.Response.Redirect(@"http://www.myRedirect.org"); // but as I said that doesn't redirect as I want it to be } } Any ideas about that?

• Sharing ASP.NET State databases between multiple apps

  - by MikeWyatt

  Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.

• Externalize Javascript in YAP

  - by Haseeb Khan

  I am working on a Yahoo! App which requires certain external Javascript Frameworks to be loaded and used. Also in the Yahoo! App Best Practices Guide, it is also mentioned that the sources should be externalized, however, externalization isn't working for me. I am using the standard procedure to load the external JS file like the following: <script src="http://www.google.com/js/nxsl.1.js"></script> But the above statement is giving me an error that external sources are not allowed. Is there any way to use external JS files as I don't want to include all of my JS Login inline, it doesn't make sense to me and majorly my code won't be re-usable. Any thoughts ?
