  • Code Signing Services

    - by bogdan
    I'm developing a System Preference Pane that runs a background application. I'm planning on codesigning the background application and I'll be using the kill flag of codesign (http://gemma.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man1/codesign.1.html). From my understanding, this kill flag will not allow the background application to be run if it's signature doesn't match. My problem with this approach is that it doesn't provide any feedback to the user and, for somewhat reason, the application gets corrupted, it will refuse to launch without any information. I'd like to use the Code Signing Service from the System Preference Pane to check the validity of the background application. However, I couldn't find how to use it to check the validity of an external file. Is this possible using the Code Signing Service or should I NSTask codesign directly? My application is targeted for 10.6 so it doesn't matter which I use. Thank you!

  • Computer Vision application(+web interface) for face detection and recognition from database

    - by Kush
    My project is a computer vision java application which should implement the following : A web interface through which the form entry+images(for example a student data) will be stored into a database(Mysql) & images into directory common to my java application. Then the data & images can be retrieved from my java Gui application and I can perform the following operations of image processing through OpenCV. Actually,I want to run the face detection on images retrieved and discard the false entries(no proper face). Also the application user/admin can search an image based on text search(By Id) or By another reference image using face recognition. I am well familiar with Java but the problem is that I need a guidance on how to organise it in a stepwise manner(links appreciated).OpenCv,Php and mySql are really messy.I know doing the openCV stuff within java is real overhead but i really want to do it.But If there is any suggestion to do it elseway please guide me.So any kind of help is a ray of hope for me. Thanks.

  • DataBinding a DropDownList in ASP.NET MVC 2

    - by Daniel Coffman
    I'm extremely frustrated trying to switch to MVC after a couple years of webforms development. Here's my extremely simple problem that I can't manage to solve: I have a list of States in a table called StateProvince. I have a DropDownList. I want the DropDownList to display all of the States in the StateProvince table and post the selected state back on HTTP PUT. This is what I'm doing: <%: Html.DropDownListFor(model = model.StateProvinceId, new SelectList(Model.StateProvinces, "StateProvinceId", "Name") )% I'm getting an Object reference not set to an instance of an object. Why? How can I make this work? Keep it simple, I know nothing about MVC.

  • Distribute EXE without config file (Webservice in WinForm)

    - by Marc vB
    I have created a WinForm app (VB.NET 2008) that references to a webservice which was added via "Add Service Reference". The app works ok. Question is about distribution of the app. It looks like I need to install the app's config file with the EXE, however I don't want that because the config files shows the actual url of the web service which is not whatt I want. So, is it possible to use a webservice in a WinForm app and only have to install the resulting EXE?

  • Access 2003 - Embedded ppt slide or Excel Spreadsheet in a form, how do I communicate?

    - by Justin
    So if I was to take a an access form, and embed either an excel spreadsheet into it, or a powerpoint slide/pres, how would I reference it in VBA code? So I know I have to set the libraries, name the frame of the OLE object, and use applicable syntax to whatever I want to do, with whatever I stick in the form, however the only things I have ever done with excel and/or powerpoint is automate the opening of a seperate window/application from access, not within the access form....so I am not sure?? if I said its a new Excel.Application, then set xls = to (the ss in the file, and not some file path of another excel file somewhere)? does that make sense?

  • Trouble setting up php Zend include path

    - by behrk2
    Hello, I am trying to set up a PHP path to my Zend Framework. I am very confused on how to do this. My Zend Framework is located at the following location on my server: amazon/ZendFramework-1.10.3-minimal I am going to be creating a couple of php files in the amazon/ directory that will require the Zend Framework. My include path is: include("ZendFramework-1.10.3-minimal/library/Zend/Service/Amazon.php"); This works, however inside of Amazon.php is the line require_once 'Zend/Rest/Client.php'; ...and then Client.php has more dependencies set up like that, and so on. How can I set up my include path so that Amazon.php and Client.php (and so on) can correctly reference the location of the Zend Framework? Thanks

Can anyone help. I'm new to appscript and python in general.

  • Unity Register two interfaces as one singleton

    - by Christian
    Hi all, how do I register two different interfaces in Unity with the same instance... Currently I am using _container.RegisterType<EventService, EventService>(new ContainerControlledLifetimeManager()); _container.RegisterInstance<IEventService>(_container.Resolve<EventService>()); _container.RegisterInstance<IEventServiceInformation>(_container.Resolve<EventService>()); which works, but does not look nice.. So, I think you get the idea. EventService implements two interfaces, I want a reference to the same object if I resolve the interfaces. Chris

  • HyperJAXB and IDREFs

    - by finrod
    I have eventually managed to fiddle HyperJAXB so that when XSD has complexType A and this has an IDREF to complexType B, then HyperJAXB will generate @OneToOne JPA annotations between the the two generated entities. However now I'm facing another problem: the XSD has complex type X that can IDREF to either complex type Y or complex type Z. In the end, I need instance of complex type X contain reference to either instance of class Y or class Z. Do you have any wild ideas how can this be done without manual alterations to the generated classes? And at the same time to make sure these entities are marshalled to a correct XML? How about using the JAXB plugin that allows generating classes so that they implement a particular interface? Could that lead anywhere?

  • Why am I getting unexpected output trying to write a hash structure to a file?

    - by Harm De Weirdt
    I have a hash in which I store the products a customer buys (%orders). It uses the product code as key and has a reference to an array with the other info as value. At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items) This is how I do rewrite the inventory: sub rewriteInventory{ open(FILE,'>inv.txt'); foreach $key(%inventory){ print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n" } close(FILE); } where $inventory{$key}[x] is 0 → Title, 1 → price, 2 → quantity. The problem here is that when I look at inv.txt afterwards, I see things like this: CD-911|Lady Gaga - The Fame|15.99|21 ARRAY(0x145030c)||| BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12 ARRAY(0x145bee4)||| Where do these ARRAY(0x145030c)||| entries come from? Or more important, how do I get rid of them?

  • Configuring log4net appenders via XML file *and* code

    - by Dave
    I started to play with log4net today and so far, I really like it. In order to preserve our current logging functionality, the app needs to create a new log file whenever the application is started. The log file name has the date and time stamp encoded in it. Currently, I've got log4net configured via an XmlConfigurator, which works great, except that the filename for my RollingFileAppender is hardcoded in the configuration XML file. I'd like to continue to use the XmlConfigurator, but after calling Configure(), I want to get at the RollingFileAppender and, in code, change its file value to be a dynamically-generated string. The sample documentation online seems to be down right now, but I've poked through the SDK reference, and it looks like I could use the Heirarchy and GetAppenders() to do what I need to do. Am I on the right track?

  • [Python] Detect destination of shortened, or "tiny" url

    - by conradlee
    I have just scraped a bunch of Google Buzz data, and I want to know which Buzz posts reference the same news articles. The problem is that many of the links in these posts have been modified by URL shorteners, so it could be the case that many distinct shortened URLs actually all point to the same news article. Given that I have millions of posts, what is the most efficient way (preferably in python) for me to detect whether a url is a shortened URL (from any of the many URL shortening services, or at least the largest) Find the "destination" of the shortened url, i.e., the long, original version of the shortened URL. Does anyone know if the URL shorteners impose strict request rate limits? If I keep this down to 100/second (all coming form the same IP address), do you think I'll run into trouble?

  • MEF part unable to import Autofac autogenerated factory

    - by Michael Wagner
    This is a (to me) pretty weird problem, because it was already running perfectly but went completely south after some unrelated changes. I've got a Repository which imports in its constructor a list of IExtensions via Autofacs MEF integration. One of these extensions contains a backreference to the Repository as Lazy(Of IRepository) (lazy because of the circular reference that would occur). But as soon as I try to use the repository, Autofac throws a ComponentNotRegisteredException with the message "The requested service 'ContractName=Assembly.IRepository()' has not been registered." That is, however, not really correct, because when I break right after the container-build and explore the list of services, it's there - Exported() and with the correct ContractName. I'd appreciate any help on this... Michael

  • Java method overloading + double dispatch

    - by Max
    Can anybody explain in detail the reason the overloaded method print(Parent parent) is invoked when working with Child instance in my test piece of code? Any pecularities of virtual methods or methods overloading/resolution in Java involved here? Any direct reference to Java Lang Spec? Which term describes this behaviour? Thanks a lot. public class InheritancePlay { public static class Parent { public void doJob(Worker worker) { System.out.println("this is " + this.getClass().getName()); worker.print(this); } } public static class Child extends Parent { } public static class Worker { public void print(Parent parent) { System.out.println("Why this method resolution happens?"); } public void print(Child child) { System.out.println("This is not called"); } } public static void main(String[] args) { Child child = new Child(); Worker worker = new Worker(); child.doJob(worker); } }

  • Populating an association with children in factory_girl

    - by Craig Walker
    I have a model Foo that has_many 'Bar'. I have a factory_girl factory for each of these objects. The factory for Bar has an association to Foo; it will instantiate a Foo when it creates the Bar. I'd like a Factory that creates a Foo that contains a Bar. Ideally this Bar would be created through the :bar factory, and respect the build strategy (create/build) used to create the Foo. I know I could just call the :bar factory and then grab the Foo reference from the new Bar. I'd like to avoid this; in my test case, the important object is Foo; calling the Bar factory seems a bit circuitous. Also, I can see the need for a Foo with multiple Bars. Is this possible in factory_girl? How do you define this relationship in the parent?

  • Does a Collection<T> wrap an IList<T> or enumerate over the IList<T>?

    - by Brian Triplett
    If I am exposing a internal member via a Collection property via: public Collection<T> Entries { get { return new Collection<T>(this.fieldImplimentingIList<T>); } } When this property is called what happens? For example what happens when the following lines of code are called: T test = instanceOfAbove.Entries[i]; instanceOfAbove[i] = valueOfTypeT; It's clear that each time this property is called a new reference type is created but what acctually happens? Does it simply wrap the IList<T> underneath, does it enumerate over the IList<T> and to create a new Collection<T> instance? I'm concerned about performance if this property is used in a for loop.

  • Java annotations for design patterns?

    - by Greg Mattes
    Is there a project that maintains annotations for patterns? For example, when I write a builder, I want to mark it with @Builder. Annotating in this way immediately provides a clear idea of what the code implements. Also, the Javadoc of the @Builder annotation can reference explanations of the builder pattern. Furthermore, navigating from the Javadoc of a builder implementation to @Builder Javadoc is made easy by annotating @Builder with @Documented. I've being slowing accumulating a small set of such annotations for patterns and idioms that I have in my code, but I'd like to leverage a more complete existing project if it exists. If there is no such project, maybe I can share what I have by spinning it off to a separate pattern/idiom annotation project. Update: I've created the Pattern Notes project in response to this discussion. Contributions welcome! Here is @Builder

  • Copying data across tabs

    - by Guillermo
    Hello, I got two different forms in two different tabs. One has data from our system and the other one is an interface of another, external, system in wich we need to copy data into (XML or API integration not an option here) The this is that, having open both forms - in two different tabs - i need a greasemonkey script or something similar that allows my to copy data from one form to the other (using the getValue method in Javascript). The problem right now is that I cannot figure out how to reference with a greasemonkey script one particular tab or window (to rad data from or write data to). Do you think it would be possible to do what I'm thinking to do? THANKS

  • Spreadsheet ML Text Color (Colour) Rendering

    - by Chris Roberts
    Hi All, I am writing a tool which generates some Spreadsheet ML (XML) to create an Excel spreadsheet for my users. I have defined a style as follows: <Style ss:ID="GreenText"> <Font ss:FontName="Arial" ss:Size="9" ss:Color="#8CBE50" /> </Style> This works to an extent, but when I open it in Excel the colour rendered for the text isn't the one I specified - it's a brighter version. I can use the same colour reference for a cell border and the colour is rendered correctly. Can anyone shed any light on why the text colour isn't rendered correctly? Thanks!

  • AES Encryption. From Python (pyCrypto) to .NET

    - by Why
    I am currently trying to port a legacy Python app over to .NET which contains AES encrpytion using from what I can tell pyCrpyto. I have very limited Python and Crypto experience. The code uses the snippet from the following page. http://www.djangosnippets.org/snippets/1095/ So far I believe I have managed to work out that it that it calls Crypto.Cipher with AES and the first 32 character of our secret key as the password, but no mode or IV. It also puts a prefix on the encrpyed text when it is added to database. What I can't work out is how I can decrypt the existing ecrypted database records in .NET. I have been looking at RijndaelManaged but it requires an IV and can't see any reference to one in python. Can anyone point me in the dirrection to what method could be used in .NET to get the desired result.

  • Seeking to zoom in on an image, slowly, on page load, using Jquery

    - by Heath Waller
    Hello, I am looking to give the impression of zooming in from a large image to a detailed area of that image, over time, when the page loads - using javascript (jquery, preferably). I have been given the following flash site as a reference (action happens just after title fades in): http://www.delicatessennyc.com/ Not sure if this is even possible. I know I could switch out the large image for a smaller one - but my boss is hellbent of achieving this flash-type action using javascript. Please note, I've searched the plugins and I've not found anything like what I'm looking for. And I'm so new to this type of coding that cobbling it together from scratch seems daunting. Thank you all so much.
