• ms excel find and replace @ symbol results in broken formula

  - by Loopo

  I'm trying to search and replace in excel, the column is formatted as 'Text'. Find: [@ replace with: @ Whenever this finds a match at the start of a cell i.e the cell contents start with [@ and tries to replace that with @ the result is an error 'This function is not valid' I guess that since the @ operator is for references, this is causing the cell to be interpreted differently (not as text anymore) How do I make this replacement work? Copy/paste into another program is not a good option because some of the cells contain line-breaks.

• What are incentives (if any) to use WinRT instead of .Net?

  - by Ark-kun

  Let's compare WinRT with .Net .Net .Net is the 13+ years evolution of COM. Three main parts of .Net are execution environment, standard libraries and supported languages. CLR is the native-code execution environment based on COM .Net Framework has a big set of standard libraries (implemented using managed and native code) that can be used from all .Net languages. There are .Net classes that allow using OS APIs. WPF or Silverlight provide a XAML-based UI framework .Net can be used with C++, C#, Javascript, Python, Ruby, VB, LISP, Scheme and many other languages. C++/.Net is a variation of the C++ language that allows interaction with .Net objects. .Net supports inheritance, generics, operator and method overloading and many other features. .Net allows creating apps that run on Windows (XP, 7, 8 Pro (Desktop and Metro), RT, CE, etc), Mac OS, Linux (+ other *nix); iOS, Android, Windows Phone (7, 8); Internet Explorer, Chrome, Firefox; XBox 360, Playstation Suite; raw microprocessors. There is support for creating games (2D/3D) using any managed language or C++. Created by Developer Division WinRT WinRT is based on COM. Three main parts of WinRT are execution environment, standard libraries and supported languages. WinRT has a native-code execution environment based on COM WinRT has a set of standard libraries that more or less can be used from WinRT languages. There are WinRT classes that allow using OS APIs. Unnamed Silverlight clone provides a XAML-based UI framework WinRT can be used with C++, C#, Javascript, VB. C++/CX is a variation of the C++ language that allows interaction with WinRT objects. Custom WinRT components don't support inheritance (classes must be sealed), generics, operator overloading and many other features. WinRT allows creating apps that run on Windows 8 Pro and RT (Metro only); Windows Phone 8 (limited). There is support for creating games (2D/3D) using C++ only. Ordered by Windows Team I think that all the aspects except the last ones are very important for developers. On the other hand it seems that the most important aspect for Microsoft is the last one. So, given the above comparison of conceptually identical technologies, what are incentives (if any) to use WinRT instead of .Net?

• drupal bootstrap script: how to get list of all nodes of type x?

  - by groovehunter

  hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

  - by George

  Hello Everyone, I would really appreciate your help with finding out how long it takes a 1-3 year experenced programmer to convert a few HTML pages into joomla 1.5 dynamic pages. I know that some of it depends on how complex the pages are but i'm talking about average pages. That's my first question, my other question is how long will it take a 1-3 year experenced programmer to install all of these componants: Video module, photo gallery module, vertuemart shopping cart. I pay programmers to do this work but i have to make as sure as i can that i'm not over paying them. Thanks in advance for answering these two questions...George

• NewBie Question, jQuery: How can we implement if...else logic and call function

  - by Rachel

  I am new to jQuery and so don't mind this question if it sounds stupid but here is something that I am trying to do : I have 3 functions like: AddToCart Function which adds item to the shopping cart: //offer_id is the offer which we are trying to add to cart. addToCart: function(offer_id) { this.submit({action: 'add', 'offer_id': offer_id}, {'app_server_url': this.app_server_url}); }, RemoveFromCart which removes data from the cart //target is link clicked and event is the click event. removeFromCart: function(target, event) { this.uniqueElmt('cart_table').find('.sb_item_remove').unbind('click'); var offer_id = $(target).parent().find('.offer_id').html(); this.submit({action: 'remove', 'offer_id': offer_id, 'next_action': this.config.current_action}, {'app_server_url': this.app_server_url}); }, Get the current state of the cart //return string which represents current state of cart. getCartItems: function() { return this.contents; } Now I am trying to do 3 things: if there is no content in cart and addToCart is called than some action, so basically here we need to check the current state of cart and that is obtained by calling getCartItems and if it is Null and than if addToCart is called than we perform some action if there is content in the cart and addToCart is called than some action,so basically here we need to check the current state of cart and that is obtained by calling getCartItems and check if it is Null or not and than if addToCart is called than we perform some action if we had some content in the cart. if there is content in the cart and removeFromCart is called some action, so basically here we need to check the current state of cart and that is obtained by calling getCartItems and if it is not Null and if removeFromCart is called than we perform some action Pseudocode of what I am trying to do: if there is no content in cart and addToCart is called than $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scAdd,scOpen', 'linkType' : 'o', 'linkName' : 'Cart : First Product Added' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scAdd,scOpen', }, } 'defer' : '0' } ); if there is content in the cart and addToCart is called than $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scAdd', 'linkType' : 'o', 'linkName' : 'Cart : Product Added' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scAdd', }, }, 'defer' : '0' } ); if there is content in the cart and removeFromCart is called $(document).track( { 'module' : 'Omniture', 'event' : 'instant', 'args' : { 'linkTrackVars' : 'products,events', 'linkTrackEvents' : 'scRemove', 'linkType' : 'o', 'linkName' : 'Cart : Product Removed' // could be blank, but can include event name as added feature 'svalues' : { 'products' : ';OFFERID1[,;OFFERID2]', 'events' : 'scRemove', }, } 'defer' : '0' } ); My basic concern is that am complete newbie to jQuery and JavaScript and so am not sure how can I implement if...else logic and how can I call a funtion using jQuery/JavaScript.

  - by Jonathan

  Hi! I am building a cgi application, and now I would like it to be like an application that stands and parses each connection, with this, I can have all session variables saved in memory instead of saving them to file(or anyother place) and loading them again on a new connection I am using lamp within a linux vmware but I can't seem to find how to install the module for it to work and what to change in the httpd.conf. I tried to compile the module, but I couldn't because my apache isn't a regular instalation, its a lamp already built one, and it seems that the mod needs the apache directory to be compiled.

  I'm trying to write an API wrapper in ruby and am stumped on how I can call HTTParty methods from a subclass. For instance, I want the user to create a connection to the api and then be able to query results from subclasses. module ApiWrapper class Connection include HTTParty base_uri '...' def initialize( u, p ) ... end def contacts ApiWrapper::Contact end end end module ApiWrapper class Contact def all # issue httparty get request here that is created from the Connection class end end end ## The user would do this conn = ApiWrapper::Connection.new( 'username', 'password' ) contacts = conn.contacts.all

• How to connect to the database in Magento?

  - by Click Upvote

  I'm trying to build a simple Magento Module that needs to connect to the database at the start of each page request. All tables need to be accessible to it. I've been pulling my hair out trying to understand how to do it. The best I could figure out was that I need to set this in the config.xml file of my module, but exactly what that command is/how it may be used, i haven't been able to figure out. Can someone please guide me or show me how to accomplish this? If not, would it be too bad a practice to include a custom config.php file which connects to the database manually?

• Removing the email validation requirement - Login Toboggan

  - by Rob Orr

  I'm building a premium membership site where a visitor can purchase a role and gain access to the privileged content using ubercart. I've got all that working fine, but the last tiny snag that my client wants to remove is to remove the validation email requirement that's fired when someone signs up on the site in Login Toboggan (6.1.9). I've got nothing set that is forcing this extra step and I've come to believe that this may be a feature in Drupal (acquia distro 6.22) core for any user that registers. I was hoping that this module (login toboggan) would eliminate that step but I've not as of yet been able to do so. I can allow the newly registered user access by setting that in the module, but the notification and validation email requirement still remains. Can anyone recommend a way around this? I just want them to be able to come to the site purchase their membership without any validation/confirmation email. Is this possible? Thanks - Rob

• WPF Composite - Expose EF model to all modules

  - by Tony

  Hi All, I have an application that uses WPF Composite, and I have an issue. I've got a big database that is attached to the application and I need it exposed to different modules as part of the application. What is the best way to expose my Entity Framework model to all my different modules and views inside them? Do I have one EF model or a separate one for each module and then only the tables that each module needs. The only problem being that some tables have a relationship and will have different views and those views will be in different modules. Any ideas how to resolve this?

• GPL License in closed source application

  - by Alec Smart

  Hello, This question has been asked multiple times I know. From what I understand, broadly speaking, if I include a GPL module in my app, I have to also release my app's source code for free. Now if the module is a java app (which I have modified) and included in my own java app, and say I use it as an applet on my website, do I need to distribute the source code to all the users visiting the website? Can I distribute the code only to people who ask for it? If I sell my applet, do I need to distribute the source code to all the users or ONLY to the users who purchase my applet? Thank you very much for your time.

• importing CELERY* environment variables in django settings.py causes celeryd not to start

  - by Taras

  I just spent 2 hours trying to figure out why django celery stopped working. Celery would being to start, but would stop short of printing out the configuration items, implying that it wasn't starting correct. The log would only contain The celery.decorators module along with the magic keyword arguments, are deprecated, and will be removed in version 3.0. Please use the celery.task module instead of celery.decorators, and the task.request should be used instead of the magic keyword arguments: from celery.task import task See http://bit.ly/celery22major for more information. """)) It turns out that some celery env variables that I was importing to try and fix a different problem were causing celery not to start correctly: from celery.tests.config import CELERY_QUEUES, CELERY_DEFAULT_QUEUE, CELERY_DEFAULT_ROUTING_KEY Even though I wasn't using them anywhere. Does anyone know what was happening?

• How to invoke an Objective-C Block via the LLVM C++ API?

• Loading Modules in Angular

  - by SL Dev

  I'm new to AngularJS. In my efforts to learn, I've relied on the AngularJS tutorials. Now, I'm trying to build an app using the AngularSeed project template. I'm trying to make my project as modular as possible. For that reason, my controllers are broken out into several files. Currently, I have the following: /app index.html login.html home.html javascript app.js loginCtrl.js homeCtrl.js my app.js file has the following: 'use strict'; var app = angular.module('site', ['ngRoute']); app.config(function($routeProvider, $locationProvider) { $locationProvider.html5Mode(true); $routeProvider.when('/login', {templateUrl: 'app/login.html', controller:'loginCtrl'}); $routeProvider.when('/home', {templateUrl: 'app/home.html', controller:'homeCtrl'}); $routeProvider.otherwise({redirectTo: '/login'}); }); my loginCtrl.js file is very basic at the moment. It only has: 'use strict'; app.controller('loginCtrl', function loginCtrl($scope) { } ); My homeCtrl.js is almost the same, except for the name. It looks like the following: 'use strict'; app.controller('homeCtrl', function homeCtrl($scope) { } ); My index.html file is the angularSeed index-async.html file. However, when I load the dependencies, I have the following: // load all of the dependencies asynchronously. $script([ 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js', 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular-route.min.js', 'javascript/app.js', 'javascript/loginCtrl.js', 'javascript/homeCtrl.js' ], function() { // when all is done, execute bootstrap angular application angular.bootstrap(document, ['site']); }); My problem is, sometimes my app works and sometimes it doesn't. It's almost like something gets loaded before something else. Occasionally, I receive this error. Other times, I get an error in the console window that says: 'Uncaught ReferenceError: app is not defined' in loginCtrl.js. Sometimes it happens with homeCtrl.js. What am I doing wrong? It feels like I need to have my controllers in a module and pass that module in my app.config in the app.js file. However, a) I'm not sure if that allowed and b) I'm not sure how to do it.

• How can I make the Python logging output to be colored?

  - by airmind

  Some time ago I saw a Mono application with colored output, probably because of it's log system, because all the messages were standardized. Now, Python has the logging module, and it let you specify a lot of options or customize it entirely, so I'm imagining that something like that would be possible too with Python, however I could not find it anywhere. Is there any way to make the Python logging module to output in color? What I want is for error messages to appear in red, for instance. Debug messages in blue or yellow, and so on. Of course this would probably only work on Linux, with compatible terminals (most modern terminals are), but I could fallback to the original logging output if color is not supported. Any ideas?

• In Node.JS, how do I return an entire object from a separate .js file?

  - by Matthew Patrick Cashatt

  Thanks for looking. I am new to Node.js and trying to figure out how to request an object from a separate file (rather than just requesting a function) but everything I try--exports,module-exports,etc--is failing. So, for example, if I have foo.js: var methods = { Foobar:{ getFoo: function(){return "foo!!";}, getBar: function(){return "bar!!";} } }; And now I want to call a function within an object of foo.js from index.js: var m = require('./Methods'); function fooMain(){ return m.Foobar.getFoo(); }; How do I do this? I have tried all sorts of combinations of exports and module-exports but they seem to only work if I call a discrete function that is not part of an object. Thanks!

• In Prism (CAL), how can I RegisterPresenterWithRegion instead of RegisterViewWithRegion

  - by Edward Tanguay

  I have a module in a Prism application and in its initialize method I want to register a presenter instead of a view with a region, i.e. I want to do this: PSEUDO-CODE: regionManager.RegisterPresenterWithRegion( "MainRegion", typeof(Presenters.EditCustomerPresenter)); instead of loading a view like this: regionManager.RegisterViewWithRegion( "MainRegion", typeof(Views.EditCustomerView)); The presenter would of course bring along its own view and ultimately register this view in the region, but it would allow me to bind the presenter to the view in the presenter's constructor instead of binding the two together in XAML (which is more of a decoupled MVVM pattern which I want to avoid here). How can I add a Presenter to a Region instead of a view? namespace Client.Modules.CustomerModule { [Module(ModuleName = "CustomerModule")] public class CustomerModule : IModule { private readonly IRegionManager regionManager; public CustomerModule(IRegionManager regionManager) { this.regionManager = regionManager; } public void Initialize() { regionManager.RegisterViewWithRegion("MainRegion", typeof(Views.EditCustomerView)); } } }
