  • mingw 3.4.5 missing dlfcn.h?

    - by lurscher
    Hi, is it possible that my mingw 3.4.5 installation is faulty? or is this provided on some other library floating around? in case you are wondering, dlfcn.h is where stuff like dlopen and dlclose are defined, so it should be pretty standard

  • Get methods covered by a unit test

    - by Victor Hurdugaci
    Is is possible to do the following from a Visual Studio 2010 plugin? If yes, how? Run all unittests in solution (with code coverage enabled) Wait for all tests to complete For successfully completed tests: Determine which methods were called during each test (directly by the test or indirectly by the tested methods). What I actually don't know is how to interact with the testing framework...

  • What does the * symbol do near a function argument and how to use that in others scenarios?

    - by user502052
    I am using Ruby on Rails 3 and I would like to know what means the presence of a *simbol near a function argument and to understand its usages in others scenarios. Example scenario (this method was from the Ruby on Rails 3 framework: def find(*args) return to_a.find { |*block_args| yield(*block_args) } if block_given? options = args.extract_options! if options.present? apply_finder_options(options).find(*args) else case args.first when :first, :last, :all send(args.first) else find_with_ids(*args) end end end

  • Getting Dictionary<string,string> from List<Control>

    - by codymanix
    I want a dictionary containing the names and text of all controls. Is it possible with predefined framework methods/LINQ/colection initializers or do I have to make a loop and add all entries by myself? This gives me an error message: List<Control> controls; // .. initialize list .. controls.ToDictionary((Control child,string k)=>new KeyValuePair<string,string>(child.Name, child.Text));

  • GPL liscensed frameworks on eccommerce websites

    - by Adam McMahon
    Ok this may be a foolish question, but I just want some clarification on this. If you build a website on a GPL licensed web framework, let's say a browser based game or some kind of kind of sophisticated web application are you required to redistribute all the code? If this is so what licenses would allow you to build on top of an opensource project without requiring you to redistribute the code?

  • Pintura OR Perserve 2.0 - Production Ready?

    - by Scott
    I'm very interested in this framework, coupled with a NoSQL backend like MongoDB. Basically, my blue-sky vision is this: ExtJS/Pintura/MongoDB. I would probably plug in Rhino as the js engine. Is there anybody here using Pintura in a production environment? What are the pitfalls? What is your general experience? Thanks.

  • How does the setup bootstrapper detect if prerequisites are installed?

    - by Marek
    Trying to solve this problem. I would like to learn how the bootstrapper detects if prerequisites (specifically .NET 3.5) are installed. According to this reference, a way to detect if .NET is installed is to check the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5 Using process monitor, I have inspected registry queries done by the bootstrapper (setup.exe) and it did not show any access to this registry key. Does anybody know how the bootstrapper determines whether the prerequisites are installed on the target system?

  • How do I validate XML via RELAX NG in Ruby?

    - by cdleary
    The REXML module appears to have support for RELAX NG validation, but the docs don't have any real information on using the validation portion of the framework. How would you validate an XML document with a RELAX NG schema? A code snippet would be most helpful. TIA!

  • Reasons to start a new project in COBOL

    - by luvieere
    Are there any feasible reasons to start a new project in COBOL? What benefits of this language one would find convincing enough to start a new project in it? I'm thinking more about viewing the language in terms of Behavior Driven Development, something related to the steps involved in using a framework such as Cucumber, only that behavior description and step definition would be integrated into one unit by using tha language's features.

  • In Jetty, can NCSARequestLog be configured to auto-detect the time zone?

    - by David Moles
    It looks as though in 2003 or so NCSARequestLog would pick up the system time zone using TimeZone.getDefault().getID(), but in more recent versions it seems as though it's hard-coded to GMT, unless you override it in jetty.xml or programmatically. If true, this kind of annoying, since it means if you don't want GMT logging you have to edit jetty.xml for every installation (not to mention twice a year for daylight saving time). Is there a workaround that will let Jetty pick the time zone up from the system?

  • How to select and AMI when creating an instance of EC2

    - by Prashant
    I am using Amazon EC2 for the first time, and need to create an instance that runs Windows, MSSQL Server 2008, .Net Framework 3.5 SP1 and IIS Server 6.0. I am unable to decide what AMI (out of the huge list of community AMIs) should I choose to meet my requirements. Is there a way I can make this decision without doing trial and error.

  • Validating method arguments with Data Annotation attributes

    - by schemer
    The "Silverlight Business Application" template bundled with VS2010 / Silverlight 4 uses DataAnnotations on method arguments in its domain service class, which are invoked automagically: public CreateUserStatus CreateUser(RegistrationData user, [Required(ErrorMessageResourceName = "ValidationErrorRequiredField", ErrorMessageResourceType = typeof(ValidationErrorResources))] [RegularExpression("^.*[^a-zA-Z0-9].*$", ErrorMessageResourceName = "ValidationErrorBadPasswordStrength", ErrorMessageResourceType = typeof(ValidationErrorResources))] [StringLength(50, MinimumLength = 7, ErrorMessageResourceName = "ValidationErrorBadPasswordLength", ErrorMessageResourceType = typeof(ValidationErrorResources))] string password) { /* do something */ } If I need to implement this in my POCO class methods, how do I get the framework to invoke the validations OR how do I invoke the validation on all the arguments imperatively (using Validator or otherwise?).

  • Adobe Flex 4.0 vs Silverlight 4.0

    - by Jason Towne
    While this not necessarily a technical question, I believe it will help a lot of developers (including myself!). With Silverlight 4.0 and Flex 4.0 both in beta, I thought I would put out an open question to the community and see what everyone likes and dislikes about each framework and why. I've worked with Flex in the past but have decided to take another look at Silverlight with the new version being released. Thoughts anyone? Edit: Made it a community wiki. :)
