  • Does table (string, string) require index?

    - by abatishchev
    In my database running on SQL Server 2008 R2 I have a special table for global variables: CREATE TABLE global_variables ( name NVARCHAR(50), value NVARCHAR(50) NOT NULL CONSTRAINT PK_global_variables PRIMARY KEY CLUSTERED ( name ASC ) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO Does such table require indexing on value or not?

  • Does -localizedDescription of NSError return the actual localized string, or does it return a key fo

    - by mystify
    Must I do something like this? NSString *errorDescription = [error localizedDescription]; NSString *errorInfoStr = NSLocalizedString(errorDescription, nil); Or do I use NSLocalizedString already when populating the userInfo dictionary with the NSLocalizedDescriptionKey key and value? So the value for that is not actually a key for NSLocalizedString, but it is the actual localized string ready to show up on screen?

  • Detect when a new property is added to a Javascript object?

    - by UICodes
    A simple example using a built-in javascript object: navigator.my_new_property = "some value"; //can we detect that this new property was added? I don't want to constantly poll the object to check for new properties. Is there some type of higher level setter for objects instead of explicitly stating the property to monitor? Again, I don't want to detect if the property value changed, but rather when a new property is added. Ideas? thanks

  • Validating event usurps button click on Windows Form

    - by triskelion
    I have a ComboBox and a Save button on my Windows Form. When I change the selected value in the ComboBox then click the Save button, the ComboBox validating event fires but the button click is lost. When the selected value is valid this results in the user thinking they have saved the change when in fact they have not. Why is the button click lost if the ComboBox is valid? Is there a work around?

  • SharePoint (2010): Field for (multi) currency...?

    - by TomTom
    Hello, old problem now getting new. Anyone has a good idea for storing currency values in a sharepoint list? Problem is - there is a currency field, but it is not multi-currency enabled. I could obviously store the value in two fields (currency lookup from a list, value in second field), but I take it as wondering whether there is a more viable approach that.

  • PHP's form bracket trick is to Django's ___?

    - by Matt
    In PHP you can create form elements with names like: category[1] category[2] or even category[junk] category[test] When the form is posted, category is automatically turned into a nice dictionary like: category[1] => "the input value", category[2] => "the other input value" Is there a way to do that in Django? request.POST.getlist isn't quite right, because it simply returns a list, not a dictionary. I need the keys too.

  • Specify a base classes template parameters while instantiating a derived class?

    - by DaClown
    Hi, I have no idea if the title makes any sense but I can't find the right words to descibe my "problem" in one line. Anyway, here is my problem. There is an interface for a search: template <typename InputType, typename ResultType> class Search { public: virtual void search (InputType) = 0; virtual void getResult(ResultType&) = 0; }; and several derived classes like: template <typename InputType, typename ResultType> class XMLSearch : public Search<InputType, ResultType> { public: void search (InputType) { ... }; void getResult(ResultType&) { ... }; }; The derived classes shall be used in the source code later on. I would like to hold a simple pointer to a Search without specifying the template parameters, then assign a new XMLSearch and thereby define the template parameters of Search and XMLSearch Search *s = new XMLSearch<int, int>(); I found a way that works syntactically like what I'm trying to do, but it seems a bit odd to really use it: template <typename T> class Derived; class Base { public: template <typename T> bool GetValue(T &value) { Derived<T> *castedThis=dynamic_cast<Derived<T>* >(this); if(castedThis) return castedThis->GetValue(value); return false; } virtual void Dummy() {} }; template <typename T> class Derived : public Base { public: Derived<T>() { mValue=17; } bool GetValue(T &value) { value=mValue; return true; } T mValue; }; int main(int argc, char* argv[]) { Base *v=new Derived<int>; int i=0; if(!v->GetValue(i)) std::cout<<"Wrong type int."<<std::endl; float f=0.0; if(!v->GetValue(f)) std::cout<<"Wrong type float."<<std::endl; std::cout<<i<<std::endl<<f; char c; std::cin>>c; return 0; } Is there a better way to accomplish this?

  • PHP OOP: Chainable objects?

    - by Industrial
    Hi everybody, I have tried to find a good introduction on chainable OOP objects in PHP, but without any good result yet. How can something like this be done? $this->className->add('1','value'); $this->className->type('string'); $this->classname->doStuff(); Or even: $this->className->add('1','value')->type('string')->doStuff(); Thanks a lot!

    I'm having a string where i'm using some placeholders to replace it with some values based on an object. It is like the following: Hello User <#= UserName #> I need to replace the <#= UserName # with a value. How can this be done with a regex? Please help. I dont want a string replace solution. There are somany placeholders and hardcoding the <#= UserName # and replace with the value is pointless

  • Convert from float to QByteArray

    - by radix07
    Is there a quick way to convert a float value to a byte wise (hex) representation in a QByteArray? Have done similar with memcpy() before using arrays, but this doesn't seem to work too well with QByteArray. For example: memcpy(&byteArrayData,&floatData,sizeof(float)); Can go the other way just fine using: float *value= (float *)byteArrayData.data(); Am I just implementing this wrong or is there a better way to do it using Qt? Thanks

  • Controling page number shwon in printing dialog

    - by Matthias Wandel
    I'm trying to implement printing a range of pages in c# While printing, the .net framework throws up a message box that says "Page # of document". This starts at 1, and counts up to the number of pages printed. If I'm printing pages 10-11, I want that count to start at 10, not 1. Is there a way to set the starting value? The logical thing would be if it started at PrinterSettings.FromPage, but it ignores that value.

  • What do I need to change to get this 'acts_as_rateable' Rails plugin working with this code from the

    - by tepidsam
    Hello! I'm working my way through the 'Foundation Rails 2' book. In Chapter 9, we are building a little "plugins" app. In the book, he installs the acts_as_rateable plugin found at http://juixe.com/svn/acts_as_rateable. This plugin doesn't appear to exist in 2010 (the page for this "old" plugin seems to be working again...it was down when I tried it earlier), so I found another acts_as_rateable plugin at http://github.com/azabaj/acts_as_rateable. These plugins are different and I'm trying to get the "new" plugin working with the code/project/app from the Foudations 2 book. I was able to use the migration generator included with the "new" plugin and it worked. Now,though, I'm a bit confused. In the book, he has us create a new controller to work with the plugin (the old plugin). Here's the code for that: class RatingsController < ApplicationController def create @plugin = Plugin.find(params[:plugin_id]) rating = Rating.new(:rating => params[:rating]) @plugin.ratings << average_rating redirect_to @plugin end end Then he had us change the routing: map.resources :plugins, :has_many => :ratings map.resources :categories map.root :controller => 'plugins' Next, we modified the following to the 'show' template so that it looks like this: <div id="rate_plugin"> <h2>Rate this plugin</h2> <ul class="star-rating"> <li> <%= link_to "1", @plugin.rate_it(1), :method => :post, :title => "1 star out of 5", :class => "one-star" %> </li> <li> <%= link_to "2", plugin_ratings_path(@plugin, :rating => 2), :method => :post, :title => "2 stars out of 5", :class => "two-stars" %> </li> <li> <%= link_to "3", plugin_ratings_path(@plugin, :rating => 3), :method => :post, :title => "3 stars out of 5", :class => "three-stars" %> </li> <li> <%= link_to "4", plugin_ratings_path(@plugin, :rating => 4), :method => :post, :title => "4 stars out of 5", :class => "four-stars" %> </li> <li> <%= link_to "5", plugin_ratings_path(@plugin, :rating => 5), :method => :post, :title => "5 stars out of 5", :class => "five-stars" %> </li> </ul> </div> The problem is that we're using code for a different plugin. When I try to actually "rate" one of the plugins, I get an "unknown attribute" error. That makes sense. I'm using attribute names for the "old" plugin, but I should be using attributes names for the "new" plugin. The problem is...I've tried using a variety of different attribute names and I keep getting the same error. From the README for the "new" plugin, I think I should be using some of these but I haven't been able to get them working: Install the plugin into your vendor/plugins directory, insert 'acts_as_rateable' into your model, then restart your application. class Post < ActiveRecord::Base acts_as_rateable end Now your model is extended by the plugin, you can rate it ( 1-# )or calculate the average rating. @plugin.rate_it( 4, current_user.id ) @plugin.average_rating #=> 4.0 @plugin.average_rating_round #=> 4 @plugin.average_rating_percent #=> 80 @plugin.rated_by?( current_user ) #=> rating || false Plugin.find_average_of( 4 ) #=> array of posts See acts_as_rateable.rb for further details! I'm guessing that I might have to make some "bigger" changes to get this plugin working. I'm asking this question to learn and only learn. The book gives code to get things working with the old plugin, but if one were actually building this app today it would be necessary to use this "new" plugin, so I would like to see how it could be used. Cheers! Any ideas on what I could change to get the "new" plugin working?

  • How to build array of 'bad' values

    - by JM4
    I am processing a form and in turn, receiving a response code based on the information submitted. I have a list of approximately 40 response codes (and their meaning) in my hands and am trying to build an 'if' statement that checks against a predefined array and returns a specific value. Just not sure how to do this First pass conceptually: $bads = array (1,2,3,4,5,6) if ($output['responsecode'] == (any value in $bads) { echo "you suck"; }
