  • Getting started with Express - Error: Cannot find module './routes'

    - by Enrico Tuttobene
    I am just getting started in the world of Node.JS, and I tried using the command line "express" command to install a basic application (with jade support) Now, I was playing around with it a bit to see how it works and I am coming across a strange error: In the /routes directory there is a file called index which contains exports.index = function(req, res){ res.render('index', { title: "Express" }); }; that, as you all know, renders the index page. Well, all I did was renaming that file from index.js to router.js, so that I can easily refer to it as I would like to have more than just an index page. The renaming doesn't work, I get the error Error: Cannot find module './routes' Which is weird, as I though that var express = require('express'), routes = require('./routes'); would require ALL the files in the directory. There must be something small there I'm missing, and please bare with me as I am pretty new to this. Thanks in advance.

  • Find key of parent in array / PHP

    - by 106691756905536410593
    Perhaps someone can help me out with this one: I'm using a basic search function to find an array deep within an array. The problem is, once that array is found, I'd also like to return it's parent key. Is there a PHP function that can determine the parent key of an array? Below is an example of the Search Function... Ideally I'd like to return the array that is found, as well as it's parent key. function search($array, $key, $value){ $results = array(); if (is_array($array)){ if ($array[$key] == $value){ $results[] = $array; } foreach ($array as $subarray){ $results = array_merge($results, search($subarray, $key, $value)); } } return $results; }

  • 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.

  • UDDI - find service which name matches exactly name specified in request

    - by empi
    Hi. I'm asking UDDI to find a service with a name specified in request. The code looks like this: UddiConnection uddiConnection = new UddiConnection(uddiAddress); FindService findService = new FindService(); findService.Names.Add(uddiServiceName); ServiceList foundServices = findService.Send(uddiConnection); However, when I ask for SomeService and UDDI has two services SomeService and SomeServiceSecond I get both in found services. How can I ask for service that name exactly matches the name specified? I know I can check the result in my class and limit found services collection but I would like to specify my needs in UDDI inquire. Thanks in advance for help.

  • Find the xmlHttpRequest resource in aspx page

    - by DJStroky
    I'm trying to find an xmlHttpRequest or similar resource that I can query directly to obtain an xml file for my own purposes. At this site it is possible to browse a Google Map mashup with markers. Unfortunately it is only possible to view all markers at a small view range, whereas I simply want to obtain all the information at once for the entire state. Using the firebug console in firefox I can enter the following javascript line to obtain the xml that I desire: document.getElementById("stationXML").value I tracked this document element down to an <input> tag, but I can't figure out how that input is set. Thanks in advance for your help!

  • Android: Where to find the RadioButton Drawable?

    - by Peterdk
    Ok, I am trying to create a custom view called CheckedRelativeLayout. It's purpose is the same as a CheckedTextView, to be able to use it in a list of items you want selected or in a Spinner. It's all working fine now, I extended RelativeLayout and implemented Checkable interface. However, I am stuck on a quite simple problem: Where can I find the Drawable that CheckedTextView and RadioButton use? I looked at the sourcecode of both, and they seem to use com.android.internal.R. Well... that's internal stuff. So I can't access it. Any way to get these Drawables or solve the problem somehow?

  • JBoss 4.3 eap can't find war in an ear

    - by Steveo
    I'm trying to deploy an ear to JBoss. The application.xml has entries looking like: <module id="Core_JavaModule"> <java>APP-INF/lib/core.jar</java> </module> <module id="Public_WebModule"> <web> <web-uri>public.war</web-uri> <context-root>/</context-root> </web> </module> The core.jar is read in OK, but when it tries to read public.war, I get: org.jboss.deployment.DeploymentException: Failed to find module file: public.war I've confirmed that the war directory is there; it is an exploded war. Not a war file. Is JBoss looking for a war file? Or will it grok a war directory?

  • Using LINQ to find a common prefix?

    - by Roger Lipscombe
    I've got two sequences: IEnumerable<string> x = new[] { "a", "b", "c" }; IEnumerable<string> y = new[] { "a", "b", "d", "e" }; I'd like to find the common prefix of these two sequences (i.e. "a", "b"). Is there a succinct way to do this in LINQ? Bear in mind that these aren't really IEnumerable<string>; they're IEnumerable<PathComponent>, where I have an implementation of IEqualityComparer<PathComponent>.

  • Cmake suddenly can't find my source files anymore...

    - by aheld
    To make a long story short: To add insult to injury, CMake actually ran fine several times. I was wrestling with a compiler error when CMake suddenly didn't feel like working anymore. For reference, here's the whole CMakeLists.txt file: set(CMAKE_INCLUDE_CURRENT_DIR ON) Find_Package ( SDL REQUIRED ) Find_Package ( SDL_image REQUIRED ) Find_Package ( SDL_mixer REQUIRED ) if ( NOT SDL_FOUND ) message ( FATAL_ERROR "Make sure that SDL is installed" ) endif ( NOT SDL_FOUND ) link_libraries ( ${SDL_LIBRARY} ${SDLIMAGE_LIBRARY} ${SDLMIXER_LIBRARY} SDLmain ) set(wiggle_SOURCES level.cpp levelgenerator.cpp main.cpp player.cpp scoreboard.cpp snake.cpp soundplayer.cpp titlescreen.cpp ) add_executable(Wiggle ../${wiggle_SOURCES}) The error occured for the first time when, instead of simply typing "make", I typed "make -lSDL -lSDL_image -lSDL_mixer" - make refused to find the header files SDL.h and SDL_image.h after I detached the project from Code::Blocks.

  • Compiling and executing through commandLine shows NoClassDefFoundError when trying to find Java pack

    - by eruina
    I have a client/server program that attempts to send and receive an object. There are three packages: server, client and shared shared contains only the Message class I put Message.java from shared package into the same folder as calcclient package source files and calcserver package source files. I compile using the line: javac -classpath .; Message.java They can compile. Then I change directory up one level and ran with: java -classpath .; .Main When I use Netbeans to run, the entire program works as per normal. But not if I run from command line. If its executed through command line, the program will work until it needs to use the Message object. Then it will show a NoClassDefFoundError Am I putting the right files at the right places? How do I get the program to find shared package through command line?

  • Find subset with K elements that are closest to eachother

    - by Nima
    Given an array of integers size N, how can you efficiently find a subset of size K with elements that are closest to each other? Let the closeness for a subset (x1,x2,x3,..xk) be defined as: 2 <= N <= 10^5 2 <= K <= N constraints: Array may contain duplicates and is not guaranteed to be sorted. My brute force solution is very slow for large N, and it doesn't check if there's more than 1 solution: N = input() K = input() assert 2 <= N <= 10**5 assert 2 <= K <= N a = [] for i in xrange(0, N): a.append(input()) a.sort() minimum = sys.maxint startindex = 0 for i in xrange(0,N-K+1): last = i + K tmp = 0 for j in xrange(i, last): for l in xrange(j+1, last): tmp += abs(a[j]-a[l]) if(tmp > minimum): break if(tmp < minimum): minimum = tmp startindex = i #end index = startindex + K? Examples: N = 7 K = 3 array = [10,100,300,200,1000,20,30] result = [10,20,30] N = 10 K = 4 array = [1,2,3,4,10,20,30,40,100,200] result = [1,2,3,4]

  • Find top "n" nearby coordinates.

    - by John Hamelink
    I have a coordinate. I want to find the top "n" (n being a variable value) nearest coordinates out of several thousand rows stored on a MySQL database. I also want to be able to define maximum and minimum distances between the coordinate in question and the coordinates in the database. How best am I to go about this? Would it be bonkers to use PHP as I understand the syntax much better than MySQL? If I use a MySQL function, how do I move it between databases if I choose to switch servers? How is it stored? Lastly, what is the most efficient method of getting through all these coordinates accurately - the coordinates are all relatively close to one another? Thanks for your time, John.

  • trying to find if a file exists in a given path

    - by Yeshwanth Venkatesh
    I am fairly new to java and I am trying to find if the file specified in the LINUX path exists. private void validateFilePath(String filePath) { File dir = new File(filePath); if(dir.exists()){ System.out.println("File exists in the path " + dir); setTARGET_IMG_DIR("filePath"); return; }else{ System.out.println("File does not exists in the path: " + dir); return; } } The dir.exists works fine if I give a absolute path from my root like this /Users/yv/Documents/Eclipse-workspace/InputParser/bin/test.txt but if I give a relative path like test.txt or /InputParser/bin/test.txt it says files does not exists. I am planing on creating a jar of this projects and hence this should work with both relative path(files in the same directory) and absolute path from the root. How can I handle this ? Is it possible to search for the absolute path of that file from the root and append it to the file name ?
