  • How to create a custom ADO Multi Dimensional Catalog with no database

    - by Alan Clark
    Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.

  • Weird generics compile error.

    - by Jouke van der Maas
    I have two classes, a base class and a child class. In the base class i define a generic virtual method: protected virtual Bar Foo<T() where T : Bar {} Then in my child class i try to do this: protected override BarChild Foo() // BarChild inherits Bar { return base.Bar<T as BarChild() } Visual studio gives this weird error: The type 'T' cannot be used as type parameter 'T' in the generic type or method 'Foo()'. There is no boxing conversion or type parameter conversion from 'T' to 'Bar'. Repeating the where clause on the child's override also gives an error: Constraints for override and explicit interface implementation methods are inherited from the base method, so they cannot be specified directly So what am i doing wrong here?

  • 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?

  • JavaScript private methods

    - by Wayne Kao
    To make a JavaScript class with a public method I'd do something like: function Restaurant() { } Restaurant.prototype.buy_food = function() { // something here } Restaurant.prototype.use_restroom = function() { // something here } That way users of my class can: var restaurant = new Restaurant(); restaurant.buy_food(); restaurant.use_restroom(); How do I create a private method that my public buy_food and use_restroom methods can call but that users of the class can't call externally. In other words, I want my method implementation to be able to do: Restaurant.prototype.use_restroom = function() { this.private_stuff(); } But this shouldn't work: var r = new Restaurant(); r.private_stuff(); How do I define private_stuff as a private method so both of those hold true? I've read Doug Crockford's writeup a few times but it doesn't seem like "private" methods can be called by public methods and "privileged" methods can be called externally.

  • Binding list of objects to WPF ListView

    - by Dave Colwell
    Hi all, I have a list of objects which i want to bind to a ListView control in my WPF application. The Objects have a DataTemplate already, so no need to define that. The list of objects is a property in the codebehind file in the format list<object> When i add one object programatically, it appears fine. But when i try to bind the ItemSource of the ListBox to the list of objects, nothing shows up. I am using the following binding: ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Portfolios}" where the name of the property i am trying to bind to is Portfolios and exists on the parent window

  • doctrine2: many-to-one with non default referencedColumnName does not persist entity

    - by timaschew
    I'm using symfony 2.1.2 with FOSUserBundle. I extend the User from FOS and define a many-to-one (bidirectional) association to a Customer entity. I don't want to use primary key for the association (referencedColumnName). I will use another integer uniqe column: customer_no use FOS\UserBundle\Entity\User as BaseUser; /** * @ORM\Entity * @ORM\Table(name="t_myuser") */ class MyUser extends BaseUser { /** * @ORM\ManyToOne(targetEntity="Customer", inversedBy="user") * @ORM\JoinColumn(name="customer_no", referencedColumnName="customer_no", nullable=false) */ $public $customer; } /** * @ORM\Entity * @ORM\Table(name="t_customer") */ class Customer extends BaseEntity // provides an id (pk) { /** * @ORM\Column(type="integer", unique=true, nullable=false) */ public $customer_no; /** * @ORM\OneToMany(targetEntity="MyUser", mappedBy="customer") */ public $user; } When I try to persist (via a form) a new MyUser entity with an (already in db existing and) loaded Customer entity from db, I get this error: Notice: Undefined index: customer_no in ...\vendor\doctrine\orm\lib\Doctrine\ORM\Persisters\BasicEntityPersister.php line 608 The schema on the db is all right. //update: I fix the inversedBy and mappedBy stuff, but this is not the problem.

  • How do I set the bake command to use a different template in cakephp

    - by Gaurav Sharma
    Hi all, I wanted bake command to bake a view of my liking. So I searched bakery and found this Modify-default-HTML-produced-by-baked-templates. But after reading this I was not able to modify the template because I wanted to define some CSS in it and those files are not containing any CSS code (they contain only php code inside them). Also if I have designed my own CSS file for the new template then how do I tell bake command to pick that specified css file for new template ? I am totally confused over here. Has anybody done this similar kinda work using cakePHP. Any help would be greatly appreciable. NOTE: I am using cakePHP v 1.3 latest stable release. Thanks

  • How to add text to path?

    - by Pritorian
    Hi all. Te question is how to add text to path element. For example, I have path: Path firstPath = new Path(); firstPath.Stroke = Brushes.Black; firstPath.StrokeThickness = 1; myCanvas.Children.Add(firstPath); LineGeometry firstLine = new LineGeometry(); firstPath.Data = firstLine; And somewhere I define line's Start and End point's. The path is binded to controls (for example - two ellipses) and when I drag one of them, the line is dynamically resized and moved to be pinned to both objects. And now I wand to add some text, that would fit to this line and follow it. Any recommendations how to do this?

  • Sencha Touch 2: List does not display in Panel

    - by jrboddie
    I am working on an MVC app in Sencha Touch 2 and am having trouble getting a list to display in a nested panel. The structure of the app has a main view which is a tab panel. One of the items in the tab panel is a defined panel, xtype: 'homepanel'. An item in this panel is the list, xtype: 'newslist' that is linked to the appropriate store and model files. The list does not display unless I change its parent 'homepanel' to a type, Ext.navigation.View. What am I missing in the definition of 'homepanel' as a Panel that prevents the display of the list? Ext.define('ACSO.view.Home', { extend: 'Ext.Panel', //<--works if Ext.navigation.View xtype: 'homepanel', requires: [ 'Ext.TitleBar', 'ACSO.view.NewsList' ], config: { title: 'Home', iconCls: 'home', cls: 'home', scrollable: true, styleHtmlContent: true, items: [ { xtype: 'newslist' } ] } });

  • How do I get real integer overflows in MATLAB/Octave?

    - by marvin2k
    I'm working on a verification-tool for some VHDL-Code in MATLAB/Octave. Therefore I need data types which generate "real" overflows: intmax('int32') + 1 ans = -2147483648 Later on, it would be helpful if I can define the bit width of a variable, but that is not so important right now. When I build a C-like example, where a variable gets increased until it's smaller than zero, it spins forever and ever: test = int32(2^30); while (test > 0) test = test + int32(1); end Another approach I tried was a custom "overflow"-routine which was called every time after a number is changed. This approach was painfully slow, not practicable and not working in all cases at all. Any suggestions?

  • How can I refactor this to use an inline function or template instead of a macro?

    - by BillyONeal
    Hello, everyone :) I have a useful macro here: #define PATH_PREFIX_RESOLVE(path, prefix, environment) \ if (boost::algorithm::istarts_with(path, prefix)) { \ ExpandEnvironmentStringsW(environment, buffer, MAX_PATH); \ path.replace(0, (sizeof(prefix)/sizeof(wchar_t)) - 1, buffer); \ if (Exists(path)) return path; \ } It's used about 6 times within the scope of a single function (that's it), but macros seem to have "bad karma" :P Anyway, the problem here is the sizeof(prefix) part of the macro. If I just replace this with a function taking a const wchar_t[], then the sizeof() will fail to deliver expected results. Simply adding a size member doesn't really solve the problem either. Making the user supply the size of the constant literal also results in a mess of duplicated constants at the call site. Any ideas on this one?

  • IDL in ATL/COM: Can I publish a const of a complex type?

    - by Ptah- Opener of the Mouth
    I know how to publish a const of a simple type in IDL, for example: const long blah = 37 But I want to publish consts of complex types, with methods, or at least readable struct-like member fields. For example, perhaps a type called CarType, which has accessor fields like "get_Make", "get_Model", "get_Year", "get_BasePrice", et cetera. Then I would like to publish const instances, such as FORD_PINTO_1973. (Please don't read too much into the example, to tell me that this particular example would lend itself better to just regular classes without const instances or something like that). I have no idea how I would define, in IDL, the fact that FORD_PINTO_1973 has a Year field of 1973. Thanks in advance for any help.

  • Sum of path products in DAG

    - by Jules
    Suppose we have a DAG with edges labeled with numbers. Define the value of a path as the product of the labels. For each (source,sink)-pair I want to find the sum of the values of all the paths from source to sink. You can do this in polynomial time with dynamic programming, but there are still some choices that can be made in how you decompose the problem. In my case I have one DAG that has to be evaluated repeatedly with different labelings. My question is: for a given DAG, how can we pre-compute a good strategy for computing these values for different labelings repeatedly. It would be nice if there was an algorithm that finds an optimal way, for example a way that minimizes the number of multiplications. But perhaps this is too much to ask, I would be very happy with an algorithm that just gives a good decomposition.

  • Can Entity Framework be used for the purpose of entity/schema definition at application runtime?

    - by Kabeer
    Hello. Can 'Entity Framework' be used for the purpose of entity definition at application runtime? Ok, to make it simple, here is what I want to achieve: My application is a product. I should be able to define entities at runtime on the basis of inputs gathered from an 'authoring' user (in effect this means 'model first' approach). These entities are of course persistable. Further, after having defined the entities and their relationships, I should be able to make complex queries across them for many reasons, including reports. Is the above possible and how? So far what I have realized is that there is a dependency on Visual Studio.

  • WCF DataContract with readonly properties

    - by Asaf R
    I'm trying to return a complex type from a service method in WCF. I'm using C# and .NET 4. This complex type is meant to be invariant (the same way .net strings are). Furthermore, the service only returns it and never recieves it as an argument. If I try to define only getters on properties I get a run time error. I guess this is because no setters causes serialization to fail. Still, I think this type should be invariant. Example: [DataContract] class A { [DataMember] int ReadOnlyProperty {get; private set;} } The service fails to load due to a problem with serialization. Is there a way to make readonly properties on a WCF DataContract? Perhaps by replacing the serializer? If so, how? If not, what would you suggest for this problem? Thanks, Asaf

  • memcpy(), what should the value of the size parameter be?

    - by Tomas
    Hi, I want to copy an int array to another int array. They use the same define for length so they'll always be of the same length. What are the pros/cons of the following two alternatives of the size parameter to memcpy()? memcpy(dst, src, ARRAY_LENGTH*sizeof(int)); or memcpy(dst, src, sizeof(dst); Will the second option always work? Regardless of the content? One thing that favors the last one is that if the array were to change, it'll be some house-keeping to update the memcpy()'s. Thanks

  • Using thrift with PHP and Java

    - by Christopher McCann
    I am getting myself a bit confused about how to go about this. My plan is to use PHP to perform the final page construction and this PHP web app will contact multiple services, which i will also to develop, for the data. Lets say one of those services was done in Java. I would define a Java interface which was implemented by a concrete class. This is where I get confused - how does Thrift link the PHP web app with the java service or am I getting totally mixed up?? Thanks

  • Popularity Algorithm - SQL / Django

    - by RadiantHex
    Hi folks, I've been looking into popularity algorithms used on sites such as Reddit, Digg and even Stackoverflow. Reddit algorithm: t = (time of entry post) - (Dec 8, 2005) x = upvotes - downvotes y = {1 if x > 0, 0 if x = 0, -1 if x < 0) z = {1 if x < 0, otherwise x} log(z) + (y * t)/45000 I have always performed simple ordering within SQL, I'm wondering how I should deal with such ordering. Should it be used to define a table, or could I build an SQL with the ordering within the formula (without hindering performance)? I am also wondering, if it is possible to use multiple ordering algorithms in different occasions, without incurring into performance problems. I'm using Django and PostgreSQL. Help would be much appreciated! ^^

  • Recursive Syntax in Oslo

    - by Kevin Lawrence
    I'm writing my first DSL with Oslo and I am having a problem with a recursive syntax definition. The input has sections which can contain questions or other sections recursively (composite pattern) like this: Section: A Question: 1 Question: 2 Section: B Question: 1 End End My definition for a Section looks like this syntax Section = "Section:" id:Text body:(SectionBody)* "End Section"; Which works (but doesn't handle recursive sections) if I define SectionBody like this syntax SectionBody = (Question); but doesn't work with a recursive definition like this syntax SectionBody = (Question | Section); What am I missing?

  • Loading Youtube Iframe API with RequireJS

    - by davidgnin
    I'm trying to use the Youtube Iframe API inside a module definded with Require JS. As this API is loaded async and calls a function once is loaded, I used a requireJS plugin called "async", that worked before with google maps api. However, this time something isn't working. My module starts this way: define(['text!fmwk/widgets/video/video.html','fmwk/utils/browser','async!http://www.youtube.com/iframe_api'], function (videoTpl,root) { ... }); and chrome console fires this error: Uncaught Error: Load timeout for modules: async!http://www.youtube.com/iframe_api_unnormalized3,async!http://www.youtube.com/iframe_api http://requirejs.org/docs/errors.html#timeout If I don't use async plugin the object YT or its functions are undefinded, and the same happens if I download the API code. The API is loaded sometimes if I put an script tag in the head tag of the html file. All this is expected, but I don't understand because async plugin fails. Thank you for your attention and help :)

  • What Belongs to the Aggregate Root

    - by jlembke
    This is a practical Domain Driven Design question: Conceptually, I think I get Aggregate roots until I go to define one. I have an Employee entity, which has surfaced as an Aggregate root. In the Business, some employees can have work-related Violations logged against them: Employee-----*Violations Since not all Employees are subject to this, I would think that Violations would not be a part of the Employee Aggregate, correct? So when I want to work with Employees and their related violations, is this two separate Repository interactions by some Service? Lastly, when I add a Violation, is that method on the Employee Entity? Thanks for the help!

  • How long (max characters) can a datastore entity key_name be? Is it bad to haver very long key_names

    - by indiehacker
    What is the maximum number of characters that can be used to define the key_name of a datastore entity? Is it bad to have very long key_names? For example: Lets say we use key_names of a 170 characters, which is the length of a Twitter message 140 plus 10 numeric characters for latitude and 10 for longtitude and 10 for a timestamp. (Reasoning of such a key_name: So by using such a key_name we can easily and quickly be sure of no duplicate postings, since the same message should not come from the same place and time more than once.)

  • Global find object references in NHibernate

    - by Miral
    Is it possible to perform a global reversed-find on NHibernate-managed objects? Specifically, I have a persistent class called "Io". There are a huge number of fields across multiple tables which can potentially contain an object of that type. Is there a way (given a specific instance of an Io object), to retrieve a list of objects (of any type) that actually do reference that specific object? (Bonus points if it can identify which specific fields actually contain the reference, but that's not critical.) Since the NHibernate mappings define all the links (and the underlying database has corresponding foreign key links), there ought to be some way to do it.

  • Ruby on rails link_to syntax

    - by mizipzor
    After following a tutorial Ive found. Im now redoing it again, without the scaffolding part, to learn it better. However, editing my \app\views\home\index.html.erb to contain: <h1>Rails test project</h1> <%= link_to "my blog", posts_path> I get an error: undefined local variable or method `posts_path' for #<ActionView::Base:0x4e1d954> Before I did this, I ran rake db:create, defined a migration class and ran rake db:migrate, everything without a problem. So the database should contain a posts table. But that link_to command cant seem to find posts_path. That variable (or is it even a function?) is probably defined through the scaffold routine. My question now is; how do I do that manually myself, define posts_path?
