  • How to test if a string is inside a list of predinfined list of string in oracle pl/sql

    - by drupalspring
    I define a list a string which contains different country codes ( for example , USA ,CHINA ,HK ,JPN) How can I check that if a input variable equal to one of the country of the country list in pl/sql . I use the following code to test it but fail, how can I revise it? declare country_list CONSTANT VARCHAR2(200) := USA,CHINA,HK,JPN; input VARCHAR2(200); begin input := 'JPN'; IF input IN (country_list) DBMS_OUTPUT.PUT_LINE('It is Inside'); else DBMS_OUTPUT.PUT_LINE('It is not Inside'); END IF; end;

  • Always require a plugin to be loaded

    - by axon
    I am writing an application with RequireJS and Knockout JS. The application includes an extension to knockout that adds ko.protectedObservable to the main knockout object. I would like this to always be available on the require'd knockout object, and not only when I specify it in the dependencies. I could concat the files together, but that seems that it should be unnecessary. Additionally, I can put knockout-protectedObservable as a dependency for knockout in the requirejs shim configuration, but that just leads to a circular dependency and it all fails to load. Edit: I've solved me issue, but seems hacky, is there a better way? -- Main.html <script type="text/javascript" src="require.js"></script> <script type="text/javascript"> require(['knockout'], function(ko) { require(['knockout-protectedObservable']); }); </script> -- knockout-protectedObservable.js define(['knockout'], function(ko) { ko.protectedObservable = { ... }; });

  • Rails architecture questions

    - by justinbach
    I'm building a Rails site that, among other things, allows users to build their own recipe repository. Recipes are entered either manually or via a link to another site (think epicurious, cooks.com, etc). I'm writing scripts that will scrape a recipe from these sites given a link from a user, and so far (legal issues notwithstanding) that part isn't giving me any trouble. However, I'm not sure where to put the code that I'm writing for these scraper scripts. My first thought was to put it in the recipes model, but it seems a bit too involved to go there; would a library or a helper be more appropriate? Also, as I mentioned, I'm building several different scrapers for different food websites. It seems to me that the elegant way to do this would be to define an interface (or abstract base class) that determines a set of methods for constructing a recipe object given a link, but I'm not sure what the best approach would be here, either. How might I build out these OO relationships, and where should the code go?

  • static const double in c++

    - by Crystal
    Is this the proper way to use a static const variable? In my top level class (Shape) #ifndef SHAPE_H #define SHAPE_H class Shape { public: static const double pi; private: double originX; double originY; }; const double Shape::pi = 3.14159265; #endif And then later in a class that extends Shape, I use Shape::pi. I get a linker error. I moved the const double Shape::pi = 3.14... to the Shape.cpp file and my program then compiles. Why does that happen? thanks.

  • Finding cities close to one another using longitude and latitude

    - by Jamie
    Each user in my db is associated to a city (with it's longitude and latitude) How would I go about finding out which cities are close to one another? i.e. in England, Cambridge is fairly close to London. So If I have a user who lives in Cambridge. Users close to them would be users living in close surrounding cities, such as London, Hertford etc. Any ideas how I could go about this? And also, how would I define what is close? i.e. in the UK close would be much closer than if it were in the US as the US is far more spread out. Ideas and suggestions. Also, do you know any services that provide this sort of functionality? Thanks

  • XAML : How to change background color only in Design mode?

    - by Kave
    I have a control with white text foreground color and transparent background color. Later on this usercontrol will be added into a different control that carries the real background color. However during designing this, control due white foreground on white background in VS 2010, I can't obviously see anything. In there anyway to define a different color for just the design time? I have tried this: if (System.ComponentModel.DesignerProperties.IsInDesignTool) { LayoutRoot.Background = new SolidColorBrush(Colors.Blue); } But this doesn't work. Any tips? Thanks, Kave

  • Accessing WordPress categories from outside

    - by John
    So, I have a client that needs all the categories from their blog to be displayed on their homepage. The WordPress blog is in its own directory, /blog. I have tried the following code (taken from a tutorial, I changed the path to fit clients site): <?php // Include WordPress define('WP_USE_THEMES', false); require('blog/wp-load.php'); query_posts('showposts=1'); ?> But this code just redirects me to the install file of WordPress (it actually wrongly redirects me). It goes to http://www.site.com/wp-admin/install.php instead of http://www.site.com/blog/wp-admin/install.php. Is there a better way than this method? I would pull in the categories from the database table, but I do not currently have access. Thanks!

I need to write these title's to an array?

  • Real world examples of Ecmascript functions returning a Reference?

    - by Bergi
    Read the EcmaScript specification, section 8.7 The Reference Specification Type: The Reference type is used to explain the behaviour of such operators as delete, typeof, and the assignment operators. […] A Reference is a resolved name binding. Function calls are permitted to return references. This possibility is admitted purely for the sake of host objects. No built-in ECMAScript function defined by this specification returns a reference and there is no provision for a user-defined function to return a reference. Those last two sentences impressed me. With this, you could do things like coolHostFn() = value (valid syntax, btw). So my question is: Are there any EcmaScript implementations that define host function objects which result in Reference values?

  • Can I use memcpy in C++ to copy classes that have no pointers or virtual functions

    - by Shane MacLaughlin
    Say I have a class, something like the following; class MyClass { public: MyClass(); int a,b,c; double x,y,z; }; #define PageSize 1000000 MyClass Array1[PageSize],Array2[PageSize]; If my class has not pointers or virtual methods, is it safe to use the following? memcpy(Array1,Array2,PageSize*sizeof(MyClass)); The reason I ask, is that I'm dealing with very large collections of paged data, as decribed here, where performance is critical, and memcpy offers significant performance advantages over iterative assignment. I suspect it should be ok, as the 'this' pointer is an implicit parameter rather than anything stored, but are there any other hidden nasties I should be aware of?

  • dynamic access magic constants in php

    - by Radu
    Hello, Is there a way to shortcut this: function a($where){ echo $where; } function b(){ a(basename(__FILE__).'::'.__FUNCTION__.'()::'.__LINE__); } to something like this: define("__myLocation__", ''.basename(__FILE__).'::'.__FUNCTION__.'()::'.__LINE__.''); function a($where){ echo $where; } function b(){ a(__mYLocation_); } I know that this cannot be done with constants (is just an theoretical example), but I can't find a way to shorthen my code. If a use a function to get my line it will get the line where that function is not the line from where the function was called. I usualy call a function that prints directly to the log file, but in my log I need to know from where the function was called, so i use basename(__FILE__).'::'.__FUNCTION__.'()::'.__LINE__ this will print something like: index.php::b()::6 It is a lot of code when you have over 500 functions in different files. Is there a shorten or better way to do this? Thank you.

  • bitfield mask calculation macro

    - by Aidan Cully
    We have a set of C macros, here, for using the preprocessor to do bitfield operations, and we run into warnings when attempting to use these macros in visual studio. The problem can be demonstrated very easily: #define BITFIELD_WIDTHMASK(Width) \ ((Width) >= 32 ? ~0x0ul : (1ul << (Width)) - 1) unsigned long foo(void) { return BITFIELD_WIDTHMASK(32); } Compiling this with MSVC yields the warning: test.c(12) : warning C4293: '<<' : shift count negative or too big, undefined behavior This isn't a behavior problem - the << operator won't be used in this case, and that should be detected at compile time. But does anyone have any suggestions about how to rewrite the macro to avoid the warning? Or, failing that, how to redesign the macro interface for this? Thanks in advance

  • Using selector to change TextView text color

    - by rafuru
    I'm trying to use a TextView to define the style of a TabWidget on a tabhost. I just created a selector for bgcolor and works fine, but i want to make a selector for textColor but the text color don't change: This is my tab_text_selector.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_selected="true" android:color="@android:color/white" /> <item android:state_focused="true" android:color="@android:color/white" /> <item android:state_pressed="true" android:color="@android:color/white" /> </selector> And this is the code when i'm trying to use on a textView: TextView txtTab=new TextView(this); txtTab.setTextColor(R.drawable.tab_text_selector); txtTab.setBackgroundResource(R.drawable.tab_bg_selector); txtTab.setGravity(Gravity.CENTER); txtTab.setText("Agregar Idea"); I know the text color must be white in any case but it doesn't.

  • C++ design with static methods

    - by user231536
    I would like to define as class X with a static method: class X { static string get_type () {return "X";} //other virtual methods } I would like to force classes which inherit from X to redefine the get_type() method and return strings different from "X" (I am happy if they just redefine get_type for now). How do I do this? I know that I cannot have virtual static methods. Edit: The question is not about the type_id, but in general about a static method that should be overriden. For example class X { static int getid() {return 1;} }

  • Is XML-RPC bad used as a protocol for a public API implementation?

    - by Jack Duluoz
    I need to implement a web API for a project I'm working on in this period. I read there are many standard protocols to do it: XML-RPC, SOAP, REST. Apparently, the XML-RPC one is the easiest one to implement and use from what I saw, but I didn't find anything about using it to implement an API. Instead I found many tutorial about creating a REST API in PHP, for example. Is there any counter-indication for using XML-RPC to implement a public web API? Also, more generally speaking, I could (sort of) define a custom protocol for my API, to keep things simpler (i.e. accepting only GET request containing the parameters I need): would this be so bad? Is using a standard protocol a must-do?

  • Random access view in boost::multi_array

    - by linai
    Here is a boost example: typedef boost::multi_array<double, 1> array_type; typedef array_type::index index; array_type A(boost::extents[100]); for(index i = 0; i != A.size(); ++i) { A[i] = (double)i; } // creating view array_type::index_gen indices; typedef boost::multi_array_types::index_range range; array_type::array_view<1>::type myview = A[ indices[range(0,50)] ]; What this code does is creating a subarray or view mapping onto the original array. This view is continuous and covers from 0th to 50th elements of an original array. What if I need to explicitly define elements I'd like to see in the view? How can I create a view with indices like [1, 5, 35, 23] ? Any ideas?

  • How to make a file with .pt extension, with xml syntax highlighting and vim's plugin snipmate load p

    - by Somebody still uses you MS-DOS
    I have the following in my .vimrc: au BufNewFile,BufRead *.pt set filetype=xml This is needed because although I'm editing a file with *.pt extension, it's indeed a valid xml file: setting the filetype like this I can have syntax highlighting. I'm using vim's snipmate plugin, and tried to create pt.snippets to specific needs since these files are Zope Page Templates (ZPT with TAL). Now, I have a problem: I don't want to create these snippets in xml.snippets, since they aren't really generic xml snippets, but my *.pt files are set to xml, so when I define my pt snippets they aren't loaded unless I run :set filetype=pt on my pt file on vim - but then I lose syntax highlighting. I would like to be able to have a pt file, with xml syntax highlighting, to be able to load a pt.snippets file from snipmate. How can I do it? (I would like to avoid putting my snippets in a generic snippet file, I would like it to be present only in pt.snippets to be easier to maintain.)

  • Expected Class-name before { token

    Hi All, I am trying to figure out whey I get an error: expected class-name before { token Here is the relative source to the error: #pragma once #ifndef H_FXACTION #define H_FXACTION #include "CP_M_RefCounted.h" #include "FxTypes.h" #include "string" #include "FxString.h" #include "FxPixels.h" #include "CP_Rect.h" #include "FxStreamable.h" #include "FxPoint.h" #include "FxPtr.h" #include "FxImage.h" #include "FxSleekStreaming.h" typedef FxID FxActionType; typedef FxUInt32 FxActionID; FxActionID FrMakeUniqueActionID(void); class FxActionData; class FxActionData : public CP_M_RefCounted { public: FxActionData(); FxActionData(FxBool final) :mFinal(final) { } virtual ~FxActionData(); I get the error at this line: class FxActionData : public CP_M_RefCounted What I dont get is why the line: class FxActionData; is there when you are creating the class directly under it. Isn't this a forward declaration? What things could be going on here?

  • How to determine MIME Type set by htaccess in PHP

    - by Ed Marty
    I have a .htaccess file set up to define specific MIME types in directory root/a/b/, and all of the files are in the same directory. I have a php file that wants to serve those files, in directory root/c/, and needs to determine the content-type as defined by the .htaccess file. Is there any way to do this? PHP version is 5.1.6. mime_content_type returns text/plain, and I'd rather not try to parse the .htaccess file manually. I can move the file if necessary.

  • Why does OSX document atoi/atof as not being threadsafe?

    - by Larry Gritz
    I understand that strtol and strtof are preferred to atoi/atof, since the former detect errors, and also strtol is much more flexible than atoi when it comes to non-base-10. But I'm still curious about something: 'man atoi' (or atof) on OS X (though not on Linux!) mentions that atoi/atof are not threadsafe. I frankly have a hard time imagining a possible implementation of atoi or atof that would not be threadsafe. Does anybody know why the man page says this? Are these functions actually unsafe on OS X or any other platform? And if they are, why on earth wouldn't the library just define atoi in terms of strtol, and therefore be safe?

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error.

  • Are there any Objective-C / Cocoa naming conventions for properties that are acronyms?

    - by t6d
    I have an object that models an online resource. Therefore, my object has to store the URL of the resource it belongs to. How would I name the getter and setter? MyObject *myObject = [[MyObject alloc] init]; // Set values [myObject setURL:url]; myObject.URL = url; // Get values [myObject URL]; myObject.URL; or would the following be better: MyObject *myObject = [[MyObject alloc] init]; // Set values [myObject setUrl:url]; myObject.url = url; // Get values [myObject url]; myObject.url; The former example would of course require to define the property in the following way: @property (retain, getter = URL, setter = setURL:) NSURL *url;

  • Python: How can I override one module in a package with a modified version that lives outside the pa

    - by zlovelady
    I would like to update one module in a python package with my own version of the module, with the following conditions: I want my updated module to live outside of the original package (either because I don't have access to the package source, or because I want to keep my local modifications in a separate repo, etc). I want import statements that refer to original package/module to resolve to my local module Here's an example of what I'd like to do using specifics from django, because that's where this problem has arisen for me: Say this is my project structure django/ ... the original, unadulterated django package ... local_django/ conf/ settings.py myproject/ __init__.py myapp/ myfile.py And then in myfile.py # These imports should fetch modules from the original django package from django import models from django.core.urlresolvers import reverse # I would like this following import statement to grab a custom version of settings # that I define in local_django/conf/settings.py from django.conf import settings def foo(): return settings.some_setting Can I do some magic with the __import__ statement in myproject/__init__.py to accomplish this? Is there a more "pythonic" way to achieve this?
