  • Passing an array for setting variable

    - by mathk
    Hi, I often see this idiom when reading php code: public function __construct($config) { if (array_key_exists('options', $config)) { ... } if (array_key_exists('driver_options', $config)) { ... } } Here I am concern with the way the parameter is used. If I were in lisp I would do: (defun ct (&key options driver_options) (do-something-with-option-and-driver_option)) But since I am in PHP I would rather have a constructor that take a list of parameter and let them be null if there a not require. So what do you guys think about having an array as parameter in other to do some initialization-or-whatever? In other to answer you have to take in account the point of view of the user of the function and the designer of the API. Also have you ever heard this has a code-smell? thanks

  • MDX query- How do I use a member property?

    - by WaggingSiberian
    I'm a complete newb to MDX / OLAP, "data warehousing" in general. I have the following MDX query and would like my results to display the month's number (1 = January, 12 = December). Luckily, the cube creator create a member property named "Month Number Of Year" When I try to run the query, I get the following... "Query (4, 8) The function expects a tuple set expression for the 1 argument. A string or numeric expression was used." Any suggestions for fixing this? Thanks! WITH MEMBER [Measures].[Tmp] as '[Measures].[Budget] / [Measures].[Net Income]' SELECT {[Date].[Month].Properties("Month Number Of Year")} ON COLUMNS, {[Measures].[Budget],[Measures].[Net Income],[Measures].[Tmp]} ON ROWS FROM [AnalyticsCube]

  • StructureMap - Injecting a dependency into a base class?

    - by David
    In my domain I have a handful of "processor" classes which hold the bulk of the business logic. Using StructureMap with default conventions, I inject repositories into those classes for their various IO (databases, file system, etc.). For example: public interface IHelloWorldProcessor { string HelloWorld(); } public class HelloWorldProcessor : IHelloWorldProcessor { private IDBRepository _dbRepository; public HelloWorldProcessor(IDBRepository dbRepository) { _dbRepository = dbrepository; } public string HelloWorld(){ return _dbRepository.GetHelloWorld(); } } Now, there are some repositories that I'd like to be available to all processors, so I made a base class like this: public class BaseProcessor { protected ICommonRepository _commonRepository; public BaseProcessor(ICommonRepository commonRepository) { _commonRepository = commonRepository; } } But when my other processors inherit from it, I get a compiler error on each one saying that there's no constructor for BaseProcessor which takes zero arguments. Is there a way to do what I'm trying to do here? That is, to have common dependencies injected into a base class that my other classes can use without having to write the injections into each one?

  • NHibernate - get List<long> representing primary keys?

    - by Nathan
    I have a situation where I definitely don't want to get the whole domain object. Basically, the entity has a primary key of long (.NET)/bigint(sql server 2005). I simply need to pass the primary key to an external system which will access the database directly - and since the list of ids could be large, I don't want to rehydrate the entire domain object just to get the Id. In linq2sql, I could accomplish this with a projection, but I am restricted to NHibernate 1.2.1.4000, which doesn't support Linq. Is there a way to accomplish this using NHibernate 1.2.1.4000? (I am open to using a named-query if that will work)

  • Entity Framework 4.1 (Code First) audit column

    - by Ken Pespisa
    I'm using Entity Framework 4.1 with a Code-First approach on an ASP.NET MVC site Say I have an entity named Profile that keeps track of a user's favorite book, and I want to track when the user updates their favorite book. UPDATED: Using the class below as an example, I want to set the FavoriteBookLastUpdated property to the current date whenever the value of the FavoriteBook property changes. public class Profile { public int Id { get; set; } public string Name { get; set; } public string FavoriteBook { get; set; } public DateTime? FavoriteBookLastUpdated { get; set; } } Right now I just update that field, if appropriate, in the controller's Edit action before calling the DBContext's SaveChanges() method. Is there a way I can put that logic in my model somehow? I'd prefer not to use triggers on the database side.

  • How do I correctly use two Not Exists statements in a where clause using Access SQL VBA?

    - by Bryan
    I have 3 Tables: NotHeard,analyzed,analyzed2. In each of these tables I have two columns named UnitID and Address. What I'm trying to do right now is to select all of the records for the columns UnitID and Address from NotHeard that don't appear in either analyzed or analyzed2. The SQL statement I created was as follows: SELECT UnitID, Address INTO [NotHeardByEither] FROM [NotHeard] Where NOT EXISTS( Select analyzed.UnitID FROM analyzed WHERE [NotHeard].UnitID = analyzed.UnitID) or NOT EXISTS( Select analyzed2.UnitID FROM analyzed2 WHERE [NotHeard].UnitID = analyzed2.UnitID) Group BY UnitID, Address I thought this would work since I've used the single NOT EXISTS subquery line and it has worked just fine for me in the past. The above query however returns the same data that is in the NotHeard table whereas if I take out the or NOT EXISTS part it works correctly. Any ideas as to what I'm doing wrong or how to do what I'm wanting to do?

  • How to name variables wich are structs

    - by evilpie
    Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non captialized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

  • How do I create a MessageBox in C# ?

    - by Nick Stinemates
    I have just installed C# for the first time, and at first glance it appears to be very similar to VB6. I decided to start off by trying to make a 'Hello, World!' UI Edition. I started in the Form Designer and made a button named "Click Me!" proceeded to double-click it and typed in MessageBox("Hello, World!"); I received the following error: MessageBox is a 'type' but used as a 'variable' Fair enough, it seems in C# MessageBox is an Object. I tried the following MessageBox a = new MessageBox("Hello, World!"); I received the following error: MessageBox does not contain a constructor that takes '1' arguments Now I am stumped. Please help.

  • Weak reference and Strong reference

  • Method of getting text on a windows form ( unmanaged C++ project )

    - by Donovan
    I'm in the process of learning C++. I've created a boilerplate Win32 app within VC++ 2008. I've studied through the code and am ready do do a bit of experimenting. I thought it would be cool to print all the windows messages received in the message loop to the form created via the boilerplate code. I for the life of me, can't figure out the method of getting text onto that form. I can't seem to identify and named object that I can use to reference that damn form. The best I can figure is I need to use the handle to reference the form somehow. Still, even if I did know how to reference the form, I'm not sure I know how I would create a label to display the text. Anyway, if someone could just point out what methodology I need to learn to make this happen it would be much appreciated. Thanks, Donovan

  • Using a delegate to populate a listbox

    - by Leroy Jenkins
    Ive been playing around with delegates trying to learn and I ran into one small problem Im hoping you can help me with. class myClass { OtherClass otherClass = new OtherClass(); // Needs Parameter otherClass.SendSomeText(myString); } class OtherClass { public delegate void TextToBox(string s); TextToBox textToBox; public OtherClass(TextToBox ttb) // ***Problem*** { textToBox = ttb; } public void SendSomeText(string foo) { textToBox(foo); } } the form: public partial class MainForm : Form { OtherClass otherClass; public MainForm() { InitializeComponent(); otherClass = new OtherClass(this.TextToBox); } public void TextToBox(string aString) { listBox1.Items.Add(aString); } } Obviously this doesnt compile because the OtherClass constructor is looking for TextToBox as a parameter. How would you recommend getting around the issue so I can get an object from myClass into the textbox in the form?

  • Error in Using Dynamic Data Entities WebSite in VS2012

    - by amin behzadi
    I decided to use Dynamic Data Entities website in vs2012. So, I created this website,then added App_Code directory and added a new edmx to it and named it myDB.edmx. After that I uncommented the code line in global.asax which registers the entity context : DefaultModel.RegisterContext(typeof(myDBEntities), new ContextConfiguration() { ScaffoldAllTables = true }); But when I run the website this error occurs : The context type 'myDBEntities' is not supported. how can I fix it? p.s: You now there are some differences between using L2S by Dynamic Data L2S website AND using entity framework by Dynamic Data Entities website.

  • Working effectively unit tests / Anyone tried the in-assembly approach?

    - by CodingCrapper
    I'm trying to re-introduce unit testing into my team as our current coverage is very poor. Our system is quite large 40+ projects/assemblies. We current use a project named [SystemName].Test.csproj were all the test code is dumped and organised to represent the namespaces using folders. This approach is not very scalable and makes it difficult to find tests. I've been thinking about added a Tests folder to each project, this would put the unit tests "in the developers face" and make them easy to find. The downside is the Production release code would contain references to nunit, nmocks as well as the test code and test data.... Has anyone tried this approach? How is everyone else working with unit tests on large projects? Having a Tests project per "real" project/assembly would introduce too many new projs. Thanks in advance

    Hey, i'm trying to create a c++ stomp client, my client constructor is : Client(std::string &server, short port, std::string &login, std::string &pass, Listener &listener); it gets a listener object which when Listener is the following interface : class Listener { virtual void message(StmpMessage message) =0; }; now i attempt to instantiate a client in a test class : class test : public virtual Listener { public: void message(StmpMessage message) { message.prettyPrint(); } int main(int argc, char* argv[]) { Client client("127.0.0.1", 61613, *this); return 0; } }; i'm sending this to the client because this is a listener object, i get the following error : /Users/mzruya/Documents/STOMPCPP/main.cpp:18: error: no matching function for call to 'Client::Client(const char [10], int, test&)' /Users/mzruya/Documents/STOMPCPP/Client.h:43: note: candidates are: Client::Client(std::string&, short int, std::string&, std::string&, Listener&) /Users/mzruya/Documents/STOMPCPP/Client.h:37: note: Client::Client(const Client&)

  • Making the #include square

    - by David
    I'm trying to write a makefile using CC on Solaris 10. [Only the first bit of that really matters, I think]. I have the following rule for foo.o: foo.o: foo.cc common_dependencies.h CC -c foo.cc -I../../common Unfortunately, common_dependencies.h includes all sorts of idiosyncratic trash, in directories not named '.' or '../../common' . Is this just going to have to be a brute force makefile where I ferret out all of the dependency paths? All of the dependencies are somewhere under '../..', but sometimes 1-level down and sometimes 2-levels down.

  • Rails - default value in text_field but only for new_record?

    - by jyoseph
    On a Content model have an attribute named slug. When creating a new record, I want to use a helper to populate this field, but on an existing record I want to use the value from the database. Currently I have: <%- if @content.new_record? -%> <%= f.text_field :slug, :value => "#{generate_slug(6)}" %> <%- else %> <%= f.text_field :slug %> <%- end %> But that seems a bit verbose. Is this the best way, or is there no other way? (Rails newb just trying to find the "Rails way" on issues I'm unsure of) Edit I should note that the helper is currently in /app/helpers/application_helper.rb

  • What, if any, is wrong with this definition of letrec in Scheme?

    - by Lajla
    R5RS gives proposed macro definitions for library forms of syntax: http://schemers.org/Documents/Standards/R5RS/HTML/r5rs-Z-H-10.html#%_sec_7.3 Which also defines letrec, in a very complicated way, certainly not how I would define it, I would simply use: (define-syntax letrec2 (syntax-rules () ((letrec2 ((name val) ...) body bodies ...) ((lambda () (define name val) ... body bodies ...))))) As far as I understand the semantics of letrec, which I use very often as a named let. It works in this way, however as I've had my fair share of debates with philosophers who think they can just disprove special relativity or established phonological theories, I know that when you think you have a simple solution to a complex problem, it's probably WRONG. There has got to be some point where this macro does not satify the semantics of letrec else they'd probably have used it. In this definition, the definitions are local to the body of the letrec, they can refer to each other for mutual recursion, I'm not quite sure what (if any) is wrong.

  • How do you set up your JScript (NOT JScript.NET) development environment?

    - by jJack
    In my environment, if I create a class in JScript syntax: class test{ } and then save it to a file named "test.js" and run it with wscript, I get a Microsoft JScript "Syntax error" at line 1. However, if I simply, say, write a function: function getInput() { var wshell = WScript.CreateObject("WScript.Shell"); wshell.Popup ("Do you want to continue?"); return userInput } getInput() and run it the same way, it works. Hopefully, there is something fundamentally wrong with my class definition. If that is the case, I am excited to find out.

  • How to import a module from a directory?

    - by Roman
    On my system I have two versions of Python (to call them I type python and python2 in the command line). When I use the first version of Python, I cannot import sklearn module but I can do it in the second version of Python. I would like to use the first version of python (because other modules are available there) and, at the same time, I would like to be able to import sklearn from this version of Python. My solution was to use: import sys sys.path.append('location_of_the_sklearn_module') To find the location of the sklearn module I started a python session (using the second version of python, in which sklearn works). The I type: import sklearn sklearn.__file__ As a result I got: /home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn/__init__.pyc In the session of the first version of Python I tried: import sys sys.path.append('/home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn') import sklearn Unfortunately it did not work. As a result I got: ImportError: No module named sklearn Does anybody know what I am doing wrong and if it is possible to reach the goal in the way I try?
