  • How do I get a bundle reference from inside of a plugin with carbon?

    - by Nik Reiman
    I'm writing a C++ plugin in Mac OS X using the Carbon framework (yeah, yeah, I know, Apple is deprecating Carbon, but at the moment I can't migrate this code to Cocoa). My plugin gets loaded by a master application, and I need to get a CFBundleRef reference to my plugin so that I can access it's resources. The problem is, when I call CFBundleGetMainBundle() during my plugin's initialization routines, that returns a reference to the host's bundle reference, not the plugin's. How can I get a reference to my plugin's bundle instead? Note: I would rather not use anything determined at compile-time, including calling CFBundleGetBundleWithIdentifier() with a hard-coded string identifier.

  • Sync Services With AddressBook

    - by Marcus
    Hi, I've developed an application to sync the Mac address book with another application. I was using an NSNotification (kABDatabaseChangedExternallyNotification) which are sent every time the address book is edited to do the syncing. However I found that if I 'overloaded' the address book (by adding 20 records really quickly or something) I didn't get all of the notifications. I have since found the Sync Services framework which seems to be aimed at my kind of application and it seems to work fine. The problem is that the changes are not 'pushed' to me in the same was as an NSNotification - I have to sync every 5 minutes or so. And, from what I can understand, I shouldn't use the AddressBook API directly but push changes back through sync services. This means that changes are not instant but lagged by how often address book/my app syncs. Is there any way to make it instant? or to use the NSNotifications reliably? Thanks for your time, Marc

  • Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

    - by Jascha
    I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

  • Questions every good .NET developer should be able to answer?

    - by splattne
    My company is about to hire .NET developers. We work on a variety of .NET platforms: ASP.NET, Compact Framework, Windowsforms, Web Services. I'd like to compile a list/catalog of good questions, a kind of minimum standard to see if the applicants are experienced. So, my question is: What questions do you think should a good .NET programmer be able to respond? I'd also see it as a checklist for myself, in order to see where my own deficits are (there are many...). *UPDATE: It want to make clear that we're not testing only for .NET knowledge, and that problem solving capabilities and general programming skills are even more important to us.

  • How to build an interactive search engine web interface using python

    - by asmaier
    I have build a static web interface for searching data from some tables in my PostgreSQL database. The query website consists of a simple textfield for entering the search term, the result website presents the results as a simple html table. The server side code for searching the PostgreSQL database and returning the results is written in python using psycopg2. Now I would like to add some interactive "Ajax features" to my search engine. When entering the search term I would like to be able to see a list of possible search terms like Google does it. On the results page, I would like to be able to sort the table showing the results. What would be the easiest/recommended way to implement these features for my search engine web site? Do I need a full-fledged web framework like Django for that?

  • Practices for Foreground/Background threads in .NET

    - by Andrei Taptunov
    I work with in-house legacy communication framework which exposes some high level abstractions. These abstractions are wrappers with some logic around .NET threads. When I looked at code I've noticed that some abstractions are wrappers around foreground threads while others are wrappers around background threads. The sad thing is that I don't see any logic why in some cases foreground threads are used and background in other cases. Are there any guidelines or patterns & practices when it's better to choose one over another on server side and client side (I believe there should be some difference)?

Why UIAccessibility not included in my UIkit ?

  • How can I Convert XML to an Object using Spring 3.0 mvc while making RESTful request

    - by brock
    Hi, I'm using the Spring 3.0 RC1 framework and I'm currently testing out Spring mvc. I wanted to use Spring mvc to handle restful requests. I have set up my controller to handle the URI request. I am passing in xml with the request. So on the controller I have a method like follows: public void request(RequestObject request) { doSomething(); } I am having a hard time converting the xml to the RequestObject. I haven't seen much documentation on this and I was wondering if anyone could point me in the right direction. I'm guess that you would have to annotate the RequestObject using JAXB or something in order to tell Spring to convert the xml file to RequestObject but I'm not sure. Thanks for all of your help!!

  • Legacy Database, Fluent NHibernate, and Testing my mappings

    - by sdanna
    As the post title implies, I have a legacy database (not sure if that matters), I'm using Fluent NHibernate and I'm attempting to test my mappings using the Fluent NHibernate PersistenceSpecification class. My question is really a process one, I want to test these when I build locally in Visual Studio using the built in Unit Testing framework for now. Obviously this implies (I think) that I'm going to need a database. What are some options for getting this into the build? If I use an in memory database does NHibernate or Fluent NHibernate have some some mechanism for sucking the database schema from a target database or maybe the in memory database can do this? Will I need to manually get the schema to feed to an in memory database? Ideally I would like to get this this setup to where the other developers don't really have to think about it other than when they break the build because the tests don't pass.

  • MS Analysis Services OLAP API for Python

    - by Kaloyan Todorov
    I am looking for a way to connect to a MS Analysis Services OLAP cube, run MDX queries, and pull the results into Python. In other words, exactly what Excel does. Is there a solution in Python that would let me do that? Someone with a similar question going pointed to Django's ORM. As much as I like the framework, this is not what I am looking for. I am also not looking for a way to pull rows and aggregate them -- that's what Analysis Services is for in the first place. Ideas? Thanks.

  • Address Book callback not called

    - by Oliver
    I have an iPhone app that makes use of the AddressBook.framework and uses Core Data to store these contacts. In order to make sure I update my own database when the Address Book is updated (whether via MobileMe or editing within my own app), I am subscribing to the notification as to when the Address Book is updating. I call this on startup: ABAddressBookRef book = ABAddressBookCreate(); ABAddressBookRegisterExternalChangeCallback(book, addressBookChanged, self); Which (supposedly) calls this on any editing. I have an ABPersonViewController which allows editing, and addressBookChanged never seems to get called. void addressBookChanged(ABAddressBookRef reference, CFDictionaryRef dictionary, void *context) { // The contacts controller we need to call ContactsController *contacts = (ContactsController *)context; // Sync with the Address Book [contacts synchronizeWithAddressBook:reference]; } Is there any reason for it to not be called?

  • WPF Skin Skinning Security Concerns

    - by Erik Philips
    I'm really new to the WPF in the .Net Framework (get that out of the way). I'm writing an application where the interface is very customizable by simply loading .xaml (at the moment a Page element) files into a frame and then mapping the controls via names as needed. The idea is to have a community of people who are interested in making skins, skin my application however they want (much like Winamp). Now the question arises, due to my lack of Xaml knowledge, is it possible to create malicious Xaml pages that when downloaded and used could have other embedded Iframes or other elements that could have embed html or call remote webpages with malicious content? I believe this could be the case. If this is the case then I two options; either I have an automated process that can remove these types of Xaml files by checking it’s elements prior to allowing download (which I would assume would be most difficult) or have a human review them prior to download. Are there alternatives I’m unaware of that could make this whole process a lot easier?

  • How do I set a dependency on Spring Web Services in my POM.xml

    - by Ben
    I get this on a lot of Maven dependencies, though current source of pain is Spring. I'll set a Spring version and include it like so: <spring-version>3.0.0.RELEASE</spring-version> <!-- Spring framework --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring-version}</version> </dependency> Which works as expected. I am however having problems setting my dependency on spring-ws-core for web services. The latest I can find in any repo is 2.0.0-M1. http://mvnrepository.com/artifact/org.springframework.ws/spring-ws-core Any clues on what I need to include in my maven POM to get Spring 3 web services to work :)

  • XCode newbie: How to find the source code for standard or system libraries?

    - by Jan Hettich
    XCode newbie question here: If I'm programming in C++ or objective C, and I #include or #import a library; e.g. #include <iostream> #import <Cocoa/Cocoa.h> I'm often not sure where to look for these header files in the directory structure on my Mac. In other development environments, you can right click the included or imported filename and have the option to jump to source. Is there such a feature in XCode? Also, for the standard C++ libraries and the Cocoa framework, is the source code for the implementation files available, or only the headers together with compiled link libraries? Thanks!

  • Scala Lift - Robust method to protect files from hotlinking

    - by sirjamm
    I'm attempting to implement a way to stop hotlinking and/or un-authorised access to resources within my app. The method I'm trying to add is something I've used before in PHP apps. Basically a session is set when the page is first called. The images are added to the page via the image tag with the session value as a parameter: <img src="/files/image/[handle]?session=12345" /> When the image is requested the script checks to see if the session is set and matches the provided value. If the condition is not met the serving page returns null. Right at the end to the code I unset the session so further requests from outside the scope of the page will return null. What would be the best implementation of this method within the lift framework? Thanks in advance for any help, much appreciated :)

  • Android: "Edit Source Lookup Path...".

    - by user307480
    I am developing on a Mac with Eclipse and have the skeleton for an app that implements the standard framework callbacks (onCreate, onDestroy, onPause, etc..). When I set breakpoints in the callbacks the debugger stops and displays a tab that says "ActivityThread.performLaunchActivity(ActivityThread $ActivityRecord,Intent)line:2477" and in the tab page body there is some red text that says "Source not found" and a button that says "Edit Source Lookup Path...". I have tried adding several paths via "Edit Source Lookup Path..." but can't see to find the one Eclipse is looking for. Can anyone point me in the right direction?

  • C# Windows Forms Print Dialog box click OK twice to respond

    - by sbartlett007
    I'm using Visual Studio 2008, .net Framework 3.5 for a Windows forms client-server app that I'm working on. There is a weird bug when I run the program and try to print. The print dialog box opens, but I have to click the OK button twice for it to work. After the second click it works fine, no errors. When I put a breakpoint on: if (result == DialogResult.OK) , the breakpoint doesn't trigger until the second click. Here is the code: private void tbPrint_Click(object sender, EventArgs e) { try { printDialog1.Document = pDoc; DialogResult result = printDialog1.ShowDialog(); if (result == DialogResult.OK) { pDoc.PrinterSettings.PrinterName = printDialog1.PrinterSettings.PrinterName; pDoc.Print(); } ... This is driving me crazy, and I can't see anything else that would interfere with it.

  • Clarification required re use of .NET Assemblies in GAC - Use to use Globally?

    - by Cognize
    Hi, I've done much reading and experimentation today regarding sigining of assemblies, and their installation into the GAC via various methods (mscorcfg.msc / drag and drop). What I thought, was that once a file was in the GAC, you did not need to make references from projects in Visual studio. I know that you CAN make references via the usual Add Reference, Browse etc, but I thought it was automatic. Testing proves this not to be the case. I came across a forum post looking to achieve the same outcome that suggested adding to the machine.config file under system.web as below. This did not work, it in fact broke visual studio until I removed it. <assemblies> <add assembly="Blah.Framework.Logging, Version=1.0.3806.25580, Culture=neutral, PublicKeyToken=0beed4b631ebc3cd" /> </assemblies> What I want to know, is am I right in my assumed use of assemblies in the GAC, and is there a way of making them globally available?

  • Good reasons to migrate PHP libraries to namespaces

    - by Joseph Mastey
    I have a significant number of object libraries written for PHP 5.2.5, and I'm trying to weigh the benefits of retrofitting them for namespaces. I don't have any concerns about the server PHP version at the moment, since any relevant machines are under my control, so I'm not worried about backwards compatibility. As far as the structure of the libraries, I use the same convention as Zend Framework, (Library_Module_Class_Name e.g.) so I don't currently have any naming conflicts internal to the libraries. I'd anticipate moving the Library and Module parts of those classnames to namespaces. That said, if the code is already written, is there any good reason to move over to namespaces? Thanks, Joe

  • DataAnnotations in ASP.NET MVC 2 - Stop MVC from applying RequiredAttribute to Non-nullable DateTime

    - by jwwishart
    Im trying to create a custom version of the RequiredAttribute to replace the built in one and I've got it working for properties that have strings values, but with properties that are DateTime or integer for example, the default RequiredAttribute seems to be applied automatically (IF the property is not nullable!) My problem is that i want to be able to specify a DateTime property as required using my custom required validator which gets the error message from a resources file (I don't want to have to tell the RequiredAttribute the type of the resource file and the key every time i apply it. That is why I'm making a custom one.) How can i prevent the framework from applying the required attribute to properties of type DateTime and int etc without changing them to nullable. Thanks

  • Python Django vs ASP.NET MVC

    - by eddyc05
    Hey guys ! i'm fairly new at web development scene and i was wondering if you guys can help me break up the pros and cons of using python django vs asp.net mvc besides the maturity level of its framework. I have intermediate experience with JAVA. As of right now, i'm leaning towards python but i just wanted to make sure i am making the right choice. I find myself limited with books available on asp.net web developments. I am aware that there is the storefront example on the official asp.net site. However, that tutorial was a little hard for me to follow. I've done a research around and was hoping python could be my next available choice. There are more tutorials available online for python anyways. What do you guys think??

  • ExpectedException on TestMethod Visual Studio 2010

    - by Joop
    Today I upgraded my solution with all the underlying projects from VS2008 to VS2010. Everything went well except for my unit tests. First of all only the web projects had as target framework .NET 4. All the other projects still had .NET 3.5. I changed them all to .NET 4. Now when I debug my unit tests it breaks on every exception. In 2008 it just wouldn't pass and tell me that an exception occurred. Even when I have the ExpectedException attribute defined it stops debugging on every exception. And example of one of my tests: [TestMethod] [ExpectedException(typeof(EntityDoesNotExistException))] public void ConstructorTest() { AddressType type = new AddressType(int.MaxValue); } The EntityDoesNotExistException is a custom exception and inherits Exception.
