  • Accessing smart card with Java

    - by Tom Brito
    I'm trying to learn about how does Java access smart cards, due to a project analysis. I wonder if there is any kind of virtual smart card which I could use to make some tests with Java? By the way, I've read about Java Card, and looks like it is used to run Java in cards, not to smart card data access, right?

  • why can't i delete this file on my pc

    - by ooo
    i am trying to install some software and it requires removing the following file: cd %SYSTEMROOT%\assembly\GAC rename Microsoft.Office.Interop.Outlook Microsoft.Office.Interop.Outlook.Old the problem is when i do the rename it looks like its successful but it doesn't seem to actually delete Microsoft.Office.Interop.Outlook i tried to explicitally do: del Microsoft.Office.Interop.Outlook and again it looks like it works but then when i do a "dir" i still see that file. Do you have any suggestions on why this wouldn't allow me to delete this file. I have outlook closed when i am doing this so i wouldn't think outlook is locking the file.

  • Ruby on Rails - Calendar Display

    - by user335725
    We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

  • Testcase with multitouch on Android?

    - by makke
    The TouchUtils class in the android documentation has functions like drag() [http://developer.android.com/intl/de/reference/android/test/TouchUtils.html#drag(android.test.InstrumentationTestCase,%20float,%20float,%20float,%20float,%20int)], but they do not support multi touch gestures, like a two finger swipe. Looking at the MotionEvent.obtain() methods, there does not seem to be any way of invoking a "virtual" multi touch event from a testcase. Anyone has got it working?

  • How to implement tail calls in a custom VM

    - by DeadMG
    How can I implement tail calls in a custom virtual machine? I know that I need to pop off the original function's local stack, then it's arguments, then push on the new arguments. But, if I pop off the function's local stack, how am I supposed to push on the new arguments? They've just been popped off the stack.

  • Can I extends a sub class of Proxy class?

    - by KCBérenger
    I want to create a complete (and real) 2-dimensional array. In order to use a maximum of Adobe code, I want to use ListCollectionView which can manage sort and filters. But to use a second dimension, I need to override getProperty method, like following code. package { import flash.utils.flash_proxy; import mx.collections.ListCollectionView; public class SubClass extends ListCollectionView /* extends Proxy */ { override flash_proxy function getProperty(name : *) : * { ... } override flash_proxy function setProperty(name : *, value : *) : void { ... } } } This code doesn't work. Flash Builder 4 said to me: 1004 Namespace was not found or is not a compile-time constant. If anyone has a solution or a clue...

  • How to change the size of NSImageView control from within program?

    - by Adam
    The following line of code displays an image on my application window, within an NSImageView control named outputImageView. I used Interface Builder to put the NSImageView control onto the window, initially (then bound it to outputImageView). How do I change the size of the NSImageView control within my program, so that it matches the size of the actual image I am displaying (which may change, periodically)? And what if I wanted to change the anchor point for the image (i.e., centered, left edge, bottom right, or whatever? Thanks in advance! [outputImageView setImage: outputImage];

  • How can I reference only a portion of a TextArea's htmlText block?

    - by Charles Shoults
    I have a number of very poor-quality pdf documents that look like 80's photocopies, which I'm rebuilding in Flash (Flex Builder 3 MXML application), representing paragraphs of text in TextAreas so that selected portions can be bold or italic, or whatever I need. I need a way to apply toolTips or event listeners to individual words within the block of text to link those words to a glossary. I'm perfectly happy to create a definition panel that is populated and made visible with a mouseOver, but don't know how to do it to just a portion of the text. Is there a good / clean / easy way to do this?

  • Assign TableView column binding to a specific core-data object in to-many related entity based on se

    - by snown27
    How would I assign a column of a TableView to be a specific entry in a Core Data entity that is linked to the NSArrayController via a to-many relationship? For example Entity: MovieEntity Attributes: title(NSString), releaseDate(NSDate) Relationship: posters<-->> PosterEntity Entity:PosterEntity Attributes: imageLocation(NSURL), default(BOOL) Relationships: movie<<--> MovieEntity So I have a three column table that I want to display the Poster, Title, and Release Date attributes in, but as one movie could potentially have several different style's of posters how do I get the poster column to only show the one that's marked default? Since the rest of the table is defined in Interface Builder I would prefer to keep it that way for the sake of keeping the code as clean as possible, but if this can only be done programmatically then I'm all ears. I just wanted to give preference in case there's more than one way to skin a cat, so to speak.

  • SQL Analysis Services - Dimension attributes with a "many" cardinality

    - by MonkeyBrother
    I am creating a cube with the following tables: Customer CustomerID, Name Customer Rep CustomerID, RepID Rep RepID, Name The important thing here is that there is a many to many relationship between Reps and Customers. I want to be able to ask the question "How much sales for customers working with rep 'A'?" In the data source view i set up the relationships between both customerid columns and both repid columns. I set up the rep attribute in the dimension builder and when I try to build the cube I get this error: Errors in the high-level relationship engine. the 'Rep' table that is required for a join cannot be reached based on the relationships in the data source view.

  • ASP.NET app on Apache Mono Ubuntu compiler error as log4net is unable to be found

    - by Jingo
    I'm trying to get a vulnerable practice ASP.NET web application (WebGoat.NET) installed on Apache Mono on Ubuntu. I've followed this guide and it all went smoothly; however, whenever I try to run the app I get this error: The type or namespace name `log4net' could not be found. Are you missing a using directive or an assembly reference? Log4net.dll is in the lib folder of the application directory. It's also in the /usr/lib/mono/gac directory. I'm not sure where else it needs to be. Any suggestions? Thanks!

  • How can I prevent javascript errors in my selenium tests from hanging my build system?

    - by lowellk
    We are having a problem with our selenium tests which run in IE on a virtual machine. Whenever there is a javascript error, a popup shows up and puts our system into a 'stuck' state - a user has to go clear that and restart the selenium test run. Is there a way to prevent the javascript error popup from putting the system into its stuck state? Would setting window.error be of any help here?

  • Passing data to overridden base method in C#

    - by UpTheCreek
    Bit of a dumb question, but I'm wondering what the accepted way of passing data from back to an overridden base method is in c#. e.g. I guess I could do: class A { int x; public virtual void DoStuff() { Console.WriteLine(x); } } class B : A { public override void DoStuff() { x = 1; base.DoStuff(); } } But is there a better method that for example doesn't require the use of a member variable?

  • Robotium BDD with Cucumber

    - by LucasGomes
    I want to know if you guys know how to make BDD tests with Robotium. As I research Robotium works with a different Virtual Machine (Dalvik) so I cannot run as Junit Test (Only with Android Junit Test). So I found a possible solution to run Robotium with Junit with RoboRemote https://github.com/groupon/robo-remote. But when i tried to integrate with cucumber the tests became unstable. So you guys know some way to make BDD tests using Robotium?

  • Print layout of C++ object with g++ compiler

    - by zaheer
    Is there a way to print the layout of a C++ object using the g++ compiler or any other means. A simplified example (assuming int takes 4 bytes) class A{ int a; }; class B:public A{ int b; } so the output would be A - 0 4 + a + B- 0 4 8 + A.a + b + It would be useful to understand the layout of objects (in my case virtual machine code). Thanks in advance. Regards, Zaheer

  • C++ Performance/memory optimization guidelines

    - by ML
    Hi All, Does anyone have a resource for C++ memory optimization guidelines? Best practices, tuning, etc? As an example: Class xxx { public: xxx(); virtual ~xxx(); protected: private: }; Would there be ANY benefit on the compiler or memory allocation to get rid of protected and private since there there are no items that are protected and private in this class?

  • ActiveX Deployment

    - by balexandre
    We have used for 8 years an ActiveX builder in Delphi and we are now using it on Internet Explorer over the internet (and not on local machine as it was always been the process until here) As today we use this object in the HTML: <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14"> <param name="tabName" value="AccountPlan"> </object> My question is, what are the viable methods to deploy an Active X Control over HTTP/S, what parameters should I need to append to tell where to find it (http url) and download a new one if newer is available? I got into this article from MSDN Library but refers to VB5.0 and it's dated 1997 ... Just wanna know what can I do now, as probably the tools evolved since last century All help is appreciated, Thank you.
