  • Should app using VCL migrate?

    - by Fdr
    Is VCL dead, or does it have a future as a GUI library? As CLX ended, is there any chance for cross-platform support in future releases? I've had to do some work with legacy app that uses Borland's VCL(BCB6). Now that new features have to be implemented, it's necessary to revalue alternatives. Whether to stick with VCL or migrate to some other library/framework. I've never read much what's happening in the field Embarcadero(Borland) tools. At least there seems to be only few VCL tagged questions here in SO and no much luck with google either.

  • What can cause a persistent "Reload the page to get source for" error in firebug?

    - by ripper234
    I'm trying to debug the javascript of a specific page, and I keep seeing Reload the page to get source for page.htm in Firebug. On Chrome, I'm mostly able to debug the js, but sometimes I also get a blank page. What can cause such issues? I believe I always see a blank page in Chrome if I reload while the JS console is open. If I open a new Chrome tab, load the page, and then open the JS console, everything is ok. The page I'm debugging is on a localhost server (Play Framework server), although I have seen this on other pages occasionally. This only happens with inline javascript ... js that is linked from the page is displayed fine.

  • Why is silverlight so slow? (Especially when compared to Flash)

    - by Sahat
    I hope I don't have to explain what is Silverlight to SO community. Anyway TemplateMonster.com has recently released new Silverlight themes that have been ported from Flash. Silverlight Templates | Template Monster I've noticed a significant lag on my Macbook Pro 13" in loading the template page in Silverlight. And not just Template Monster templates but other silverlight applications on the web as well. Now why is that? I've been hearing how great Silverlight is and how it's a great business platform blah blah blah. And now Microsoft plans to build Windows Phone 7 on top of Silverlight framework. As much as I want to praise Silverlight, so far it's been nothing but a disappointment to me. Could someone enlighten me, what is so great about Silverlight, and why should I put up with that starting up lag? Silverlight was really next up on my "stuff to learn" list this summer, but now I am not so sure...

  • What would be the wisest choice for a new .Net RESTful web service?

    - by Phil.Wheeler
    I want to write my first REST web service using the .Net framework. I've seen fairly passionate comments from various people about which is best and have even found some differing comments from Microsoft. My web service should be fairly simple: I want to expose bus timetable information. I figure the resources I will be concerned about are Fares Timetables (routes, stops) What would be the most appropriate (i.e. not necessarily the easiest, most fun or your personal preference) technology to use out of WCF, ADO.NET Data Services or ASP.Net MVC?

  • A consistent and simple group of IDE and tools for embedded code and unit test in C++ ?

    - by TridenT
    I’m starting a new firmware project in C++ for Texas Instrument C283xx and C6xxx targets. The unit tests will not run on the target, but will be compiled with gcc/gcov on a PC with windows (and run as well on PC) with simple metrics for tested code coverage. The whole project will be part of Cruise Control.NET for continuous integrations. My question is: what are the consistent IDE / framework / tools to work together? A/ One of the developers says CodeComposerStudio V3.1 for application and CodeBlocks + CxxUnit for the Unit tests. B/ I’m more attracted with CodeComposerStudio V4 for application, Eclipse CDT (well, as CCS V4) and CppUnit for unit test + MockCpp for mocks. I don’t want the best in class tools for each process, but a global, consistent and easy solution (or group of tools if you prefer).

  • Spring vs Hibernate

    - by Vidar
    Just trying to get my head round Spring and figuring out how I wire up an Oracle connection in xml config file, and now find out I need yet another framework! - Hibernate, this is soooo frustrating as it feels like I'm getting deeper and deeper into more and more frameworks without actually getting what I need done! I looked at Hibernate and it seems to do similar things to Spring, bearing in mind I just want to do some SQL inserts in Oracle. I am reluctant and do not have time to learn 2 frameworks - could I get away with just adopting Hibernate for the simple things I need to do?

  • How to later assign value to optional attribute of NSManagedObject in a NSManagedObjectModel having

    - by Kundan
    I am using coredata framework. In my NSManagedObjectModel i am using three entities that are Class, Student and Score where class and student have one-to-many & inverse relationship and Student and Score have also inverse but one-one relationship. Score entity has all optional attributes and having default '0' decimalVaue, which is not assigned at the time new Student is added. But later i want to assign them score individually and also to particular attribute not all of score attributes in a go. I am able to create and add Students to particular Class but dont have any idea how to call particular student and assign them score. For example I want to assign Score'attribute "dribbling" [there are many attributes like "tackling"] a decimal value to Student "David" of Class "Soccer" ,how i can do that? Thanks in advance for any suggestion.

  • Silverlight binaries what are .ni.dlls?

    - by BrettRobi
    In browsing around the Silverlight installation directory I see a number of framework DLLs as expected. But I also see a separate DLL with the same name but with .ni inserted between the dll name and extension. For example there is a System.dll and System.ni.dll. There appears to be a sister .ni dll for almost all of the system dlls. Looking at the quickly in Reflector they appear to include the same content, but are much bigger in binary size. Just out of curiosity, can anyone explain what these are?

  • Clean install of IIS 6 on Windows Server 2003 ignoring 'web.config'?

    - by Vario
    Hi, Any help with this would be really appreciated! As the title suggests, I'm running a brand new install of Windows Server 2003 and IIS 6 and I'm basically attempting to mirror a live web server onto a new internal development server, which runs the same setup. It's an ASP.NET site that relies heavily on URL rewriting (using Intelligencia). ASP.NET is set to run on v2.0.50727 on both servers. I've tried intentionally introduce syntax errors into the web.config and it just appears to be ignoring them completely, so given IIS 6 doesn't read the web.config, the rest of the site doesn't work at all (I get a 404 error, as a 'Default.aspx' doesn't exist since the web.config handles the default page rewriting). Having looked at the Application Mapping, '.config' files are set to use the default 'c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll' which exists. Is there anything else I may be missing? Thanks in advance.

  • Is there a strategy to back-port C# code?

    - by ianmayo
    Hi all, I intend using the Argotic framework in support of a .Net Atom server. Unfortunately my target server (over which I have no control) only has .Net 1.1 - any the Argotic library is only in .Net 2 and 3.5. So, I now need to back-port the code to 1.1. Can anybody provide any strategic tips for this undertaking? I'm aware of the merits of using Unit Tests to verify the ported code (here). should I be looking for automated tools? should I just import the code into VS2003 .Net 1.1 project and work through the compiler warnings? Any tips appreciated. cheers, Ian

  • Static vs Non Static constructors

    - by Neil N
    I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

  • ProgrammingError: (1146, "Table 'test_<DB>.<TABLE>' doesn't exist") when running unit test for Djang

    - by abigblackman
    I'm running a unit test using the Django framework and get this error. Running the actual code does not have this problem, running the unit tests creates a test database on the fly so I suspect the issue lies there. The code that throws the error looks like this member = Member.objects.get(email=email_address) and the model looks like class Member(models.Model): member_id = models.IntegerField(primary_key=True) created_on = models.DateTimeField(editable=False, default=datetime.datetime.utcnow()) flags = models.IntegerField(default=0) email = models.CharField(max_length=150, blank=True) phone = models.CharField(max_length=150, blank=True) country_iso = models.CharField(max_length=6, blank=True) location_id = models.IntegerField(null=True, blank=True) facebook_uid = models.IntegerField(null=True, blank=True) utc_offset = models.IntegerField(null=True, blank=True) tokens = models.CharField(max_length=3000, blank=True) class Meta: db_table = u'member' there's nothing too odd there i can see. the user running the tests has the same permissions to the database server as the user that runs the website where else can I look to see what's going wrong, why is this table not being created?

  • Using GWT to output XML, JSON and regular HTML

    - by Artem
    Sorry, this is a very basic question, as we are just getting started with exploring GWT. We would like to know if it's easy and possible to get GWT to "output" XML, JSON and regular HTML. I would like to know this because ideally we would port parts of our backends over slowly, and it would be nice to drop in GWT in place of AJAX wherever we need it during the transition period. Places that we would like to be able to use: 1) We have a pure XML page that we return to our client (mobile) app and right now this is handled through Spring MVC with a nice template. What's the best replacement for this? 2) We have a regular AJAX page that makes async requests and expects replies in JSON. Can we easily replace this backend? 3) We have some regular webpages where we use templates to output them, and we would like to first switch them over in the simplest possible way, without converting them to the regular GWT UI framework. Thanks!

  • VS 2010: Can't insert snippet using shortcut - incompatibility with resharper 5???

    - by mark smith
    Hi there, i recently installed some snippets that come with a framework i am using. And sure enought i checked via Tools > Code Snippet Manager and they are installed under "My Code Snippets". If i do insert Snipper (right click in code window) or CTRL K + CTRL X then i can search within all available snippets.... But i do believe its possible to just type the shortcut key (in this case it is mvvmlocatorproperty) and pressing tab inserts the snippet BUT when i type the shortcut key it is not recognizing anything... What am i doing wrong?? This is not an incompatibility with resharper 5? - which i have installed Any ideas really appreciated

  • MVC without ORM is not real MVC?

    - by ajsie
    at the moment im integrating ORM (doctrine) into a MVC framework (codeigniter). then it hit me that this was the obvious way of setting up a MVC: the controller calls the models that are representing database tables. look at this picture: MVC + ORM then i wondered, how can a MVC without ORM be real MVC? cause then the models are not real objects, rather aggregations of different functions that perform CRUD, then returning the result to the controller. and there is no need for a state (object properties) i guess so the functions would be all static? correct me if im wrong on this one. i guess a lot of people are using models without ORM. please share your thoughts. how do your models look like?

  • What XSS/CSRF attacks (if any) to be aware of when allowing video embeds?

    - by fireeyedboy
    I've been assigned a project for a website where users will be allowed to upload video's (using a YouTube API) but more importantly (for me) they will also be allowed to submit video embed codes (from numerous video sites, YouTube, Vimeo, etc. etc.). Having no experience with allowing users to embed video: How can I best protect against cross site scripting and/or cross site request forgery attacks specifically for video embedding? What are some of the common pitfalls to watch for? At a minumum I would think to strip all tags except <object> and <embed>. But I have a feeling this will not be enough, will it? If it is of importance, the environment will be: PHP/Zend Framework MySQL Bonuspoints: Is there a common minimum golden rule/code template for video embed codes that are valid across all video sites that I could use to filter the input?

  • Offline mode app in a (HTML5) browser possible?

    - by Horace Ho
    Is it possible to build an application inside in browser? An application means: 1 Where there is connection (online mode) between the browser and an remote application server: the application runs in typical web-based mode the application stores necessary data in offline storage, to be used in offline mode (2) the application sync/push data (captured during offline mode) back to the server when it is resumed from offline mode back to online mode 2 Where there is no connection (offline mode) between the browser and an remote application server: the application will still run (javascript?) the application will present data (which is stored offline) to user the application can accept input from user (and store/append in offline storage) Is this possible? If the answer is a yes, is there any (Ruby/Python/PHP) framework being built? Thanks

  • Ruby on Rails, PHP or C++ for web social network

    - by faya
    Hello, I have chosen diploma work in university. It's a mini social network. But now I am really stuck with which technology I should stick. I am average at C++ ISAPI web services development, below average PHP(had few projects with it) and new to Ruby and its framework RAILS. I have a deadline 1.5 month to develop it(about 5 hours every day after my full time job). Also I heard that its very easy to learn and develop with Ruby on Rails. Considering C++ I know that I have to do lots of coding and work by myself and PHP looks almost the same to me. So I am looking for you skilled developers advise what would you do in my position? Learn RoR, stick with C++ or PHP or maybe use something else?

  • How to call an event when the user "finally" selects an item in a list?

    - by herzmeister der welten
    When a user clicks once on an item in a Grid or a ListBox, that item is usually selected, hence most UI frameworks have a onSelected event or the like for that. However, how can we generally call the next step when a user "finally" selects an item by e.g. double clicking an entry? You know when some popup might appear in the context of the selected item and the user can do further stuff. Strangely enough, I think I have never seen a word for that in any UI framework. onPicked, onAccepted, onChosen, onFinallySelected, onResult? All kinda awkward or too special. Any other ideas?

  • Is there a Java equivalent for Ruby on Rails "url_for"?

    - by Oren Ben-Kiki
    I have written something like this pretty easily in C# (string GetUrl(new { controller = "foo", action = "bar", baz = "fnord" }), based on the existing capabilities of the XmlRouteCollection class provided by the ASP.NET MVC framework (why it isn't there out of the box is beyond me; the additional required code was trivial). I am now faced with a JSP project, and I need the same ability: centralize the logic for generating all URLs in one place, based on a list of routing rules. Is there some code somewhere I could reuse/adapt to do this in Java? It seems like a common enough requirement, but google proved surprisingly unhelpful in finding something like this.

  • Examples of mobile frameworks that support AdSense for mobile content ads?

    - by David Sky
    I’ve tried, I really have, to find examples of serving up AdSense for mobile content ads in any of the popular mobile frameworks, but can’t find running webpages with ads, nor tutorials, etc.... I’ve done some iUI work, but would consider jQueryMobile, iWebKit, even sencha-touch if I could find an example that actually displays ads within the framework on an iPhone, iPod touch,etc... I realize there are issues with the HTML adSense generates, but hasn’t anyone found a work-around? Surely some mobile HTML sites must be serving up ads? Links to tutorials would be much appreciated!

  • How to access Grails domain classes in Java service layer?

    - by batmannavneet
    How can I use grails domain classes (which is in groovy) in service layer which is in Java/Spring. When using the grails MVC, everything is fine as I can use controller to access domain objects and call CRUD and other dynamic methods on them. But, what I am wondering is is there a clean way to do it from Java - say the service layer. For example, I may want to develop a reporting framework where I need to use domain objects to access the DB. I Hope the question is clear. This should be a standard problem that everybody must have faced in a reasonably sized project. I am just wondering how it is solved..maybe I am missing something here. thanks.

  • ASP.NET MVC v1 project upgraded to VS 2010 no longer will debug. Why?

    - by Todd Brooks

I have a S#arp Architecture project (ASP.NET MVC v1) that has been opened and upgraded to be used in VS 2010. I can no longer debug the project. I'm running Windows 7 Ultimate x64 and Visual Studio 2010 Ultimate. I have IE set to be my default browser. I have the build set to debug. System.Web.Mvc is referenced in my project's lib dir. I've cleaned the solution. I've recompiled the solution. It's set to use .NET Framework 3.5. PDBs are being created and dropped into the bin directory with the DLLs. Any help will be greatly appreciated.

  • How can I receive messages over http without MSMQ

    - by pduncan
    I need a reliable messaging framework that runs over http/https (due to client security requirements) and that doesn't use MSMQ (because some clients will use Windows XP Home). The clients only need to be able to receive messages, not send them. We already have a message queue on the server for each user, and the receivers have been getting messages by connecting to an HttpHandler on the server and getting a Stream from WebResponse.GetResponseStream() We keep this stream open, and pull messages off of it using Stream.Read(). This MOSTLY works, but Stream.Read() is a blocking call, and we can't reliably interrupt it. We need to be able to stop and start the receiver without losing messages, but the old stream often hangs around, even after we call Thread.Abort on its thread. Any suggestions?
