PHP include once.
- by cpburns
Is it more efficient to use PHP's include_once or require_once instead of using c-like include with a header guard?
i.e,
VERSUS
//contents of init.php
if (!defined('MY_INIT_PHP')) {
define('MY_INIT_PHP', true);
...
}
?

php require class call from inside method
- by jera
from my understanding, require pastes code into the calling php file. what if you were requiring from inside a method...it would paste the entire code/class inside the method, blocking the next statement in the method. eg. function test() { require 'pathtosomeclasscode'; somestatement; // any code after the require is blocked. } how do i get around this, to be able to require code where-ever, without it being pasted in that exact spot? Thanks in advance for your help.Read the article

PHP require/include only works once in script then fails
- by Colin
Hi everybody, this isn't a problem as such but it's bugging me and I would appreciate any help. It might be totally obvious but I can't see it. $root_path = $_SERVER['DOCUMENT_ROOT'] require($root_path .'template/header.php') require($root_path .'template/footer.php') The script will include one or the other but not both. It will run and include the header but not the footer, if I swap them round it will load the footer first but not the header. I've tried using include instead of require but get the same result. It gives the error allow_url_include = 0. I know turning this on will solve it but my question is why is it happening? Why will it include one file but not the other? Is there any way to get them to both run without turning allow_url_include on (I'm trying to be security conscious). I have PHP 5.3 and am running WAMP. Thanks in advance for your help!Read the article

How to include/require/load a file in ruby with instance variables
- by doctororange
I would like to put a large variable definition in a separate file for the sake of getting it out of the way. I must be doing something wrong though, because my puts call isn't putting anything out. my_class.rb: class foobar def initialize require 'datafile.rb' puts @fat_data end end datafile.rb: @fat_data = [1,2,3,4,5,6,7,8,9,10] Can you use require this way?Read the article

PHP - Read number of dirs and then require for each a specified file name
- by Max
Hello, I want to make a little script but I'm rather n00b in php so please help me if you can :) What I want the script to do is: I have "index.php". I want "index.php" to read the sub-directories from a known folder, let's say "templates/" Each sub-directory will contain a file called "content.html". The index will then load the "content.html" with the require() function for each of the existing sub-directories. Thank you very much for your help!Read the article

How to refresh/reload page once using jQuery?

Hi! Newbie question: I'm wondering how to refresh/reload a page (or even specific div) once(!) using jQuery? Ideally in a way right after the "DOM structure" is available (cf. "onload" event) and not negatively affecting "back button" or "bookmark" functionalities. Please note: ''replace('' is not allowed due to third-party restrictions.

Click Once Deployment Process and Issue Resolution
- by Geordie
Introduction We are adopting Click Once as a deployment standard for Thick .Net application clients. The latest version of this tool has matured it to a point where it can be used in an enterprise environment. This guide will identify how to use Click Once deployment and promote code trough the dev, test and production environments. Why Use Click Once over SCCM If we already use SCCM why add Click Once to the deployment options. The advantages of Click Once are their ability to update the code in a single location and have the update flow automatically down to the user community. There have been challenges in the past with getting configuration updates to download but these can now be achieved. With SCCM you can do the same thing but it then needs to be packages and pushed out to users. Each time a new user is added to an application, time needs to be spent by an administrator, to push out any required application packages. With Click Once the user would go to a web link and the application and pre requisites will automatically get installed. New Deployment Steps Overview The deployment in an enterprise environment includes several steps as the solution moves through the development life cycle before being released into production. To make mitigate risk during the release phase, it is important to ensure the solution is not deployed directly into production from the development tools. Although this is the easiest path, it can introduce untested code into production and result in unexpected results. 1. Deploy the client application to a development web server using Visual Studio 2008 Click Once deployment tools. Once potential production versions of the solution are being generated, ensure the production install URL is specified when deploying code from Visual Studio. (For details see ‘Deploying Click Once Code from Visual Studio’) 2. xCopy the code to the test server. Run the MageUI tool to update the URLs, signing and version numbers to match the test server. (For details see ‘Moving Click Once Code to a new Server without using Visual Studio’) 3. xCopy the code to the production server. Run the MageUI tool to update the URLs, signing and version numbers to match the production server. The certificate used to sign the code should be provided by a certificate authority that will be trusted by the client machines. Finally make sure the setup.exe contains the production install URL. If not redeploy the solution from Visual Studio to the dev environment specifying the production install URL. Then xcopy the install.exe file from dev to production. (For details see ‘Moving Click Once Code to a new Server without using Visual Studio’) Detailed Deployment Steps Deploying Click Once Code From Visual Studio Open Visual Studio and create a new WinForms or WPF project. In the solution explorer right click on the project and select ‘Publish’ in the context menu. The ‘Publish Wizard’ will start. Enter the development deployment path. This could be a local directory or web site. When first publishing the solution set this to a development web site and Visual basic will create a site with an install.htm page. Click Next. Select weather the application will be available both online and offline. Then click Finish. Once the initial deployment is completed, republish the solution this time mapping to the directory that holds the code that was just published. This time the Publish Wizard contains and additional option. The setup.exe file that is created has the install URL hardcoded in it. It is this screen that allows you to specify the URL to use. At some point a setup.exe file must be generated for production. Enter the production URL and deploy the solution to the dev folder. This file can then be saved for latter use in deployment to production. During development this URL should be pointing to development site to avoid accidently installing the production application. Visual studio will publish the application to the desired location in the process it will create an anonymous ‘pfx’ certificate to sign the deployment configuration files. A production certificate should be acquired in preparation for deployment to production. Directory structure created by Visual Studio Application files created by Visual Studio Development web site (install.htm) created by Visual Studio Migrating Click Once Code to a new Server without using Visual Studio To migrate the Click Once application code to a new server, a tool called MageUI is needed to modify the .application and .manifest files. The MageUI tool is usually located – ‘C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin’ folder or can be downloaded from the web. When deploying to a new environment copy all files in the project folder to the new server. In this case the ‘ClickOnceSample’ folder and contents. The old application versions can be deleted, in this case ‘ClickOnceSample_1_0_0_0’ and ‘ClickOnceSample_1_0_0_1’. Open IIS Manager and create a virtual directory that points to the project folder. Also make the publish.htm the default web page. Run the ManeUI tool and then open the .application file in the root project folder (in this case in the ‘ClickOnceSample’ folder). Click on the Deployment Options in the left hand list and update the URL to the new server URL and save the changes. When MageUI tries to save the file it will prompt for the file to be signed. This step cannot be bypassed if you want the Click Once deployment to work from a web site. The easiest solution to this for test is to use the auto generated certificate that Visual Studio created for the project. This certificate can be found with the project source code. To save time go to File>Preferences and configure the ‘Use default signing certificate’ fields. Future deployments will only require application files to be transferred to the new server. The only difference is then updating the .application file the ‘Version’ must be updated to match the new version and the ‘Application Reference’ has to be update to point to the new .manifest file. Updating the Configuration File of a Click Once Deployment Package without using Visual Studio When an update to the configuration file is required, modifying the ClickOnceSample.exe.config.deploy file will not result in current users getting the new configurations. We do not want to go back to Visual Studio and generate a new version as this might introduce unexpected code changes. A new version of the application can be created by copying the folder (in this case ClickOnceSample_1_0_0_2) and pasting it into the application Files directory. Rename the directory ‘ClickOnceSample_1_0_0_3’. In the new folder open the configuration file in notepad and make the configuration changes. Run MageUI and open the manifest file in the newly copied directory (ClickOnceSample_1_0_0_3). Edit the manifest version to reflect the newly copied files (in this case 1.0.0.3). Then save the file. Open the .application file in the root folder. Again update the version to 1.0.0.3. Since the file has not changed the Deployment Options/Start Location URL should still be correct. The application Reference needs to be updated to point to the new versions .manifest file. Save the file. Next time a user runs the application the new version of the configuration file will be down loaded. It is worth noting that there are 2 different types of configuration parameter; application and user. With Click Once deployment the difference is significant. When an application is downloaded the configuration file is also brought down to the client machine. The developer may have written code to update the user parameters in the application. As a result each time a new version of the application is down loaded the user parameters are at risk of being overwritten. With Click Once deployment the system knows if the user parameters are still the default values. If they are they will be overwritten with the new default values in the configuration file. If they have been updated by the user, they will not be overwritten. Settings configuration view in Visual Studio Production Deployment When deploying the code to production it is prudent to disable the development and test deployment sites. This will allow errors such as incorrect URL to be quickly identified in the initial testing after deployment. If the sites are active there is no way to know if the application was downloaded from the production deployment and not redirected to test or dev. Troubleshooting Clicking the install button on the install.htm page fails. Error: URLDownloadToCacheFile failed with HRESULT '-2146697210' Error: An error occurred trying to download <file> This is due to the setup.exe file pointing to the wrong location. ‘The setup.exe file that is created has the install URL hardcoded in it. It is this screen that allows you to specify the URL to use. At some point a setup.exe file must be generated for production. Enter the production URL and deploy the solution to the dev folder. This file can then be saved for latter use in deployment to production. During development this URL should be pointing to development site to avoid accidently installing the production application.’Read the article

jQuery click event on image only fires once
- by stephenreece@
I created a view of thumbnails. When the user clicks, I want the real image to pop-up in a dialog. That works the first time, but once the jQuery 'click' fires on an thumbnail it never fires again unless I reload the entire page. I've tried rebinding the click events on the dialog close that that does not help. Here is my code: function LoadGalleryView() { $('img.gallery').each(function(){ BindImage($(this)); }); } function BindImage(image) { var src= image.attr('src'); var id= image.attr('id'); var popurl = src.replace("thumbs/", ""); image.hover(function(){ image.attr('style', 'height: 100%; width: 100%;'); }, function(){ image.removeAttr('style'); }); $('#'+id).live('click', function() { PopUpImage(popurl); }); } function CheckImage(img,html) { if ( img.complete ) { $('#galleryProgress').html(''); var imgwidth = img.width+35; var imgheight = img.height+65; $('<div id="viewImage" title="View"></div>').html(html).dialog( { bgiframe: true, autoOpen: true, modal: true, width: imgwidth, height: imgheight, position: 'center', closeOnEscape: true }); } else { $('#galleryProgress').html('<img src="images/ajax-loader.gif" /><br /><br />'); setTimeout(function(){CheckImage(img,html);},10); } } function PopUpImage(url) { var html = '<img src="'+url+'" />'; var img = new Image(); img.src = url; if ( ! img.complete ) { setTimeout(function(){CheckImage(img,html);},10); } } PopUpImage() only executes the first time an image is clicked and I cannot figure out how to rebind.Read the article

jQuery Tools alert works once (but only once)
- by Jim Miller
I'm trying to build a simple alert mechanism with jQuery Tools -- in response to a bit of Javascript code, pop up an overlay with a message and an OK button that, when clicked, makes the overlay go away. Trivial, or it should be. I've been slavishly following http://flowplayer.org/tools/demos/overlay/trigger.html, and have something that works fine the first time it's invoked, but only that time. If I repeat the JS action that should expose the overlay, it doesn't. My content/DIV: <div class='modal' id='the_alert'> <div id='modal_content' class='modal_content'> <h2>hi there</h2> this is the body <p> <button class='close'>OK</button> </p> </div> <div id='modal_background' class='modal_background'><img src='/images/overlay/f9f9f9-180.png' class='stretch' alt='' /></div> </div> and the Javascript: function showOverlayDialog() { $('#the_alert').overlay({ mask: {color: '#cccccc', loadSpeed: 200, opacity: 0.9}, closeOnClick: false, load: true }); } As I said: When showOverlayDialog() is invoked the first time, the overlay appears just like it should, and goes away when the "OK" button is clicked. But if I cause showOverlayDialog() to run again, without reloading the page, nothing happens. If I reload the page, then the pattern repeats -- the first invocation brings up the overlay, but the second one doesn't. I'm obviously missing something -- any advice out there? Thanks!Read the article

Sql Server Prevent Saving Changes That Require Table to be Re-created
When working with SQL Server Management studio, if you use the Design view of a table and attempt to make a change that will require the table to be dropped and re-added, you may receive an error message like this one: Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that cant be re-created or enabled the option Prevent saving changes that require the table to be re-created. In truth, its quite likely that you didnt enable such an option, despite the error dialogs accusations, as it is enabled by default when you install SQL Management Studio. You can learn more about the issue in the KB article, Error message when you try to save a table in SQL Server 2008: Saving changes is not permitted. Warning: As the above article states, it is not recommended that you turn off this option (at least not permanently), as it will ensure that you do not accidentally change the schema of a table such that data is lost. Do so at your peril. The simplest way to bypass this error is to go into Option Designers and uncheck the option Prevent saving changes that require table re-creation. See the screenshot below. The main reason why you will see this error is if you attempted to do any of the following to the table whose design you are saving: Change the Allow Nulls setting for a column Reorder columns Change any columns data type Add a new column The recommended workaround is to script out the changes to a SQL file and execute them by hand, or to simply write out your own T-SQL to make the changes.

Cleanest/One-liner way to require all files in directory in Ruby?
- by viatropos
When creating gems, I often have a directory structure like this: |--lib |-- helpers.rb `-- helpers |-- helper_a.rb `-- helper_b.rb Inside the helpers.rb, I'm just require-ing the files in the helpers directory. But I have to do things like this: $:.push(File.dirname(__FILE__) + '/helpers') require 'helper_a' require 'helper_b' Is there a way to make that one line so I never have to add to it? I just came up with this real quick: dir = File.join(File.dirname(__FILE__), "helpers") Dir.entries(dir)[2..-1].each { |file| require "#{dir}/#{file[0..-4]}" } But it's two lines and ugly. What's a slick one liner to solve this problem?Read the article

How do I temporarily change the require path in Ruby ($:)?
- by John Feminella
I'm doing some trickery with a bunch of Rake tasks for a complex project, gradually refactoring away some of the complexity in chunks at a time. This has exposed the bizarre web of dependencies left behind by the previous project maintainer. What I'd like to be able to do is to add a specific path in the project to require's list of paths to be searched, aka $:. However, I only want that path to be searched in the context of one particular method. Right now I'm doing something like this: def foo() # Look up old paths, add new special path. paths = $: $: << special_path # Do work ... bar() baz() quux() # Reset. $:.clear $: << paths end def bar() require '...' # If called from within foo(), will also search special_path. ... end This is clearly a monstrous hack. Is there a better way?Read the article

Require password to login to Nexus 7
- by gnudoc
The default behavior in the Nexus 7 Image is to log straight in to the default user's desktop, bypassing the lightdm greeter. This seems like an acceptable behavior for testing the core but it's clearly insecure. I've changed the default password and would like lightdm to actually require the password to be entered, rather than just having a button that says "login". I've turned automatic login on and off in System Settings ? User Accounts but this doesn't help. Any suggestions?Read the article

In Node.js, how can I load my modules once and then use them throughout the app?
- by TIMEX
I want to create one global module file, and then have all my files require that global module file. Inside that file, I would load all the modules once and export a dictionary of loaded modules. How can I do that? I actually tried creating this file...and every time I require('global_modules'), all the modules kept reloading. It's O(n). I want the file to be something like this (but it doesn't work): //global_modules.js - only load these one time var modules = { account_controller: '/account/controller.js', account_middleware: '/account/middleware.js', products_controller: '/products/controller.js', ... } exports.modules = modules;Read the article

SFX Played Once per Collision or Hit
- by David Dimalanta
I have a question about using Box2D (engine for LibGDX used to make realistic physics). I observed on the code that I've made for the physics here below: @Override public boolean touchUp(int screenX, int screenY, int pointer, int button) { // TODO Touch Up Event if(is_Next_Fruit_Touched) { BodyEditorLoader Fruit_Loader = new BodyEditorLoader(Gdx.files.internal("Shape_Physics/Fruity Physics.json")); Fruit_BD.type = BodyType.DynamicBody; Fruit_BD.position.set(x, y); FixtureDef Fruit_FD = new FixtureDef(); // --> Allows you to make the object's physics. Fruit_FD.density = 1.0f; Fruit_FD.friction = 0.7f; Fruit_FD.restitution = 0.2f; MassData mass = new MassData(); mass.mass = 5f; Fruit_Body[n] = world.createBody(Fruit_BD); Fruit_Body[n].setActive(true); // --> Let your dragon fall. Fruit_Body[n].setMassData(mass); Fruit_Body[n].setGravityScale(1.0f); System.out.println("Eggs... " + n); Fruit_Loader.attachFixture(Fruit_Body[n], Body, Fruit_FD, Fruit_IMG.getWidth()); Fruit_Origin = Fruit_Loader.getOrigin(Body, Fruit_IMG.getWidth()).cpy(); is_Next_Fruit_Touched = false; up = y; Gdx.app.log("Initial Y-coordinate", "Y at " + up); //Once it's touched, the next fruit will set to drag. if(n < 50) { n++; }else{ System.exit(0); } } return true; } Now, I'm thinking which part o line should I implement for the sound effects. My objectives to make SFX played once for every collision (Or should I say "SFX played once per collision"?) on the following: SFX played once if they hit on the objects of its kind. (e.g. apple vs. apple) SFX played once on a different sound when it hit on the ground. (e.g. apple land on the mud) Take note that I'm using Box2D for the Java programming version thanks to LibGDX via Box2D engine and I edited the physics body using Physics Body Editor before I implement it to code. I tried to check every available methods for body, fixture definition, or body definition to code for the SFX when hit but it seems only for the gravity and weight. Is there possibly available on the document for SFX played when collision happens if possible?Read the article

Unity Launcher only runs once - requires lightdm restart before it runs again
- by Don
I have an intermittent problem that just started showing up several days ago. I am running 11.10 and all updates are current. I first saw the symptom with a custom version of the "Home" nautilus-home.desktop file I created in ~/.local.share/applications. I added a few static shortcuts to specific folders. What I found was, clikcing the icon once would open up my home folder, but after closing that nautilus window, clicking the icon again did nothing (did not even show icon backlight animation). However, I could right click on the same icon and access my short cuts as many times as I want. Symptom persisted until restarting lightdm. Just yesterday I saw the same sort of symptom happen with a custom launcher I created for a chromium-borwser to open a specific URL (with a few short cuts to other URLs). Click the icon - it works once. Then never again. Right click the icon and I can use the short cuts over and over - no problem. Note - at one point I assumed I might have a problem with my custom .desktop file, so I did a test by removing my custom nautilus-home.desktop. However, even after restarting lightdm, and verifying the home icon was the standard one from /opt/share/applications (all my custom shortcuts were gone) I saw the same symptom re-appear - it runs once and then not again until restarting lightdm. It seems to be intermittent and seems to move between various launchers. Not sure what to do or even what background data to gather. Attempt to improve question after the first answer: I tried the following: 1) remove all custom launchers 2) reboot 3) add custom lauchers back 4) reboot 5) attempt to use .... still have "runs once and never again" symptom with several launchersRead the article

Tell Us Once–Final Phase goes live
- by BizTalk Visionary
Yesterday the final phase of ‘Tell Us Once’ went live. This completes the 4 1/2 year journey Solidsoft started on this cross government project with the addition of full electronic distribution of data and the most import piece – access for the citizen to use the service on-line. Tell Us Once (TUO) is the award-winning, cross-government programme that lets people inform central government and local authorities just once of a birth or death. In service in over 95% of councils in England, Scotland and Wales, it provides a permanent solution to the long-standing and frustrating issue of people having to notify the government multiple times. Several years ago, research showed that people had to make up to 44 contacts when reporting a death to government bodies and their local authority. The TUO service is offered as a face-to-face interview by the local authority or by telephone to a dedicated telephony service run by the Department for Work and Pensions (DWP). and a now a TUO online service for death. From the bereavement section of the Direct Gov web site the citizen is able to ‘enrich’ the standard death registration data to allow the ‘Tell Us Once’ system inform the various government departments about the death. These include the local council, DVLA, DWP, Passport service and HMRC. For the record this is an excellent example of how an SME working with a large SI partner can deliver success for government in a responsive and agile manner. For me personally it is a proud moment in which a vision I started with a very small team was followed through, extended and finally delivered by an excellent team at Solidsoft.Read the article
