• Export products and variants from MSSQL

  - by mickyjtwin

  I have a SQL DB that has a table of products, and another table which contains a list of the sku variants of each product if it has one. I want to export all the products and their SKU's into excel. At the moment, I have a helper SQL function which performs the subquery against a product_id and concatenates all the SKU's into a comma-delimited string, e.g: Product Code, Name, SKUs 111 P1 77, 22, 11 Is there an easier way to do this, so that each SKU is a row which the associated product code as well, i.e: Product Code, Name, SKUs 111 P1 77 111 P1 22 111 P1 11

• How can I use SiteMap more efficiently?

  - by Bipul

  So, in our website we are using SiteMap. For each request we render some menu and to do that we do SiteMap.RootNode in the helper function. Now, when I have done the profiling of my website using dotTrace, I saw the get_RootNode() is taking lot's of time(around 70-75 millisecond). But we know that the SiteMap is static. So, I am thinking in somehow I will get the SiteMap.RootNode only once in Application_Start and will access that through out each request. So, my questions are, Is my approach correct? How should I do that? Or is there any efficient way that I can use SiteMap.RootNode Thanks.

• connecting to a webservice from android - AsyncTask or Service?

  - by football

  I'm writing an android app that will connect to a REST/JSON webservice. Users will be retrieving information, uploading comments, downloading and uploading images etc. I know that I shouldn't keep all this network communication in the Activity/UI thread, as it will cause ANRs. What I'm confused about is whether I should use an AsyncTask or a Service with "manual" threading to accomplish this; With a Service, I'd simply have a public method for each method in the webservice's API. I'd then implement threading within each of these methods. If I used an AsyncTask, I would create a helper class that defined AsyncTasks for each method in the webservice's API. Which method is preferred? Interaction with the webservice will only happen while the user is in the Activity. Once they switch to another application, or exit the program, there is no need for communication with the webservice.

• jQuery draggable leaving cloned html behind

  - by Alex Crooks

  I am using jQuery UI; Draggable http://jqueryui.com/demos/draggable invoked like this: $(document).ready(function(){ $("#side_bar").sortable({ revert: true }); $(".draggable").draggable({ containment: 'parent', hascroll: true, handle: 'div.box_header', scrollSensitivity: 100, scrollSpeed: 100, axis: 'y', connectToSortable: '#side_bar', helper: 'clone', opacity: 0.35 }); }); You can see the html structure on http://www.sarsclan.co.uk (right side bar area). It seems to create a transparant clone as your dragging, but when you drop it puts the draggable div in the right place, but leaves the original div in it's place and just appends the dom with a clone of that original div in its new place.

• Use javascript variables in Rails view helpers

  - by Horacio

  Using jqGrid I want to generate delete links for each row in the grid. The standard way to do this is to add the links in the gridComplete callback like shown below: gridComplete: function() { var ids = jQuery("#jobs_table").jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var cl = ids[i]; be = '<%= link_to(image_tag("delete.gif", :border=>0, :size=>"20x22", :alt => "delete"),· { :action => 'destroy', :id => 'cl', :method => :delete}, :class => 'ajax') -%>'; jQuery("#jobs_table").jqGrid('setRowData',ids[i],{workflow_state:be}); } }, Using getDataIDs I get a list of IDs that I can use to generate the delete links. The problem is that this is a javascript call that results in a javascript variable. The question is how can I use this variable "cl" inside rails link_to view helper?

• grails date from params in controller

  - by nils petersohn

  y is it so hard to extract the date from the view via the params in a grails controller? i don't want to extract the date by hand like this: instance.dateX = parseDate(params["dateX_value"])//parseDate is from my helper class i just want to use instance.properties = params you know :) in the model the type is java.util.Date and in the params is all the information (dateX_month, dateX_day, ...) i searched on the net and found nothing on this :( i hoped that grails 1.3.0 could help but still the same thing. i can't and will not belief that extracting the date by hand is nessesary!

• Application_End() cannot access cache through HttpContext.Current.Cache[key]

  - by Carl J.

  I want to be able to maintain certain objects between application restarts. To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start(). I currently have a cache helper class, which uses the following method to return the cached value: return HttpContext.Current.Cache[key]; Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk. Question: how can I access the cache items during Application_End()?

• Permanently write variables to a php file with php

  - by Oliver

  I need to be able to permanently change variables in a php file using php. I am creating a multilanguage site using codeigniter and using the language helper which stores the text in php files in variables in this format: $lang['title'] = "Stuff"; I've been able to access the plain text of the files using fopen() etc and I it seems that I could probably locate the areas I want to edit with with regular expressions and rewrite the file once I've made the changes but it seems a bit hacky. Is there any easy way to edit these variables permanently using php? Cheers

• Active menu tabs with codeigniter

  - by CyberJunkie

  Which method can be used in Codeigniter to achieve active menu tabs? For example I have a user menu Profile Friends Messages Logout When I'm in the profile controller the URL is domain.com/profile/some_function The Profile tab should be active by changing the background color for example. I would usually add php to the tabs to check for their corresponding URL segment and I would change the style of the active tab. In Codeigniter should I implement a helper? What function can I easily use in tabs?

• Can a single solution hold projects from multiple repositories?

  - by cyclotis04

  I've begun setting up SVN repositories to store my code, and am wondering if a single Visual Studio solution can have projects from multiple repositories. I have a shared library with different helper functions, generic custom controls, etc, that are used by multiple projects, and hosted in its own repository. Then I have my project repository, which contains all of the program-specific code such as forms, etc. I know I could copy the shared library into the program's repository, then copy them back when I make changes, but I'd much rather keep them in different repositories so I can hit "Commit" and the general library commits to it's repository, and the program code commits to it. I'm currently using AnkhSVN, but if it's possible with other tools, I'll look into it. Preemptive clarification for all the "just use one repository" answers: The shared library is hosted in an online repository, viewable by anyone, but the program code is proprietary and resides on our office servers, so they need different repositories.

• Magento Product Details Image Size

  - by Jason

  Magento 1.4 Default Product Details image size is 265x265. All of our product images will be probably 2x taller than wide, and even if we pad them to make them square 265 will be too small to see detail in the image, so we'd like to make the image taller. I found the media.phtml file How would we go about modifying this file/Magento so that the product details page image is 265W x 530H. This looks like the code that displays the image. <p class="product-image"> <?php $_img = '<img src="'.$this->helper('catalog/image')->init($_product, 'image')->resize(265).'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'" />'; echo $_helper->productAttribute($_product, $_img, 'image'); ?> </p> Thanks

• How would you implement the "tell don't ask" principle in HAML?

  - by Enrique Ramírez Vélez

  Here's the thing. I have a button that, depending on the scenario, will behave, look and have different text. Here's how it, roughly, looks like at the moment: - if params[:param_A] && @statement_A %span.button.cancel_button{attribute: "value_B"} - if @statement_B = t('locale_A') - else = t('locale_B') - elsif params[:param_A] %span.button.cancel_button{attribute: "value_A"} - if @statement_B = t('locale_A') - else = t('locale_B') There's also a CSS class both buttons should have IF statement_B is true. So it is a mess. And I recently read about the "Tell, don't ask" principle which I liked very much, so I'd love to apply it here... but I'm not sure how. I know I could make a helper, but I'd like to stay away from them because reasons (I really have some valid reasons to do so, but those are beyond the scope of this question). I can resort to that as a last resource, but would rather find another solution.

• How can I use my multiple cored dedicated server to run my java application?

  - by Delta

  I have a game built in a java environment and I use JVM. I have 4 cores @ 2.4Ghz and my server is only using one of those cores... I've tried and searched and I still have no guides to setup multiple cores to run the game like, say 1 core for running the character saving + loading, and 1 core for the server itself, and 1 core for a helper to help other cores that need more power. I don't even know if this is possible but this is all in java the operating machine is windows server 2003 and I've tried so hard I just don't know what to do. May someone please help me! Thank you so much!

• Issue with child of custom Decorator class in WPF (c#)

  - by galacticgrug

  I need a custom border that renders a little differently than a normal border. I made a class that inherited from Decorator as follows class BetterBorder : Decorator { protected override Size ArrangeOverride(Size arrangeSize) { return arrangeSize; } protected override void OnRender(DrawingContext dc) { //these values are calculated elsewhere dc.DrawGeometry(backgroundBrush, borderPen, pathGeometry); } } //Properties and helper methods below this All of this works fine until I try to add a child to the control, the control can be added but is not visible and seems to be moved off BetterBorders visible client area. If I inherit from Border everything works fine, what am I missing?

• How to add/register helpers with Zend Framework

  - by manyxcxi

  I'm just starting out with Zend Framework and am having issues using Zend_Controller_Action_HelperBroker::addPath() to add helpers. I'm not sure if my classes are named incorrectly, I'm giving it the wrong prefix, or what I'm doing wrong so I will post the code and file structure and get out of the way. In Bootstrap.php public function __construct($application) { ... // This works with a manual include_once('../application/plugins/helpers/Csrf.php'); //Zend_Controller_Action_HelperBroker::addHelper(new Application_Controller_Action_Helper_Csrf()); // This isn't picking up my helper class automagically Zend_Controller_Action_HelperBroker::addPath('../application/plugins/helpers','Application_Controller_Action_Helper'); ... } In application/plugins/helpers/Csrf.php class Application_Controller_Action_Helper_Csrf extends Zend_Controller_Action_Helper_Abstract { ... } My directory tree: / application/ ... plugins/ helpers/ Csrf.php CsrfProtect.php ...

• Surface Detection in 2d Game?

  - by GamiShini

  I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

• Rails: render a partial from a plugin

  - by Sam

  I'm getting a missing template error after I try rendering a partial from a plugin. I have included the files with the following: %w{ models controllers helpers views }.each do |dir| path = File.join(File.dirname(__FILE__), 'app', dir) $LOAD_PATH << path ActiveSupport::Dependencies.load_paths << path ActiveSupport::Dependencies.load_once_paths.delete(path) end The Models are getting loaded, but as for other things I'm not sure what's going on. The helpers are not getting loaded too because I just copied the contents of the partial from the plugin instead of the render :partial = and then it came up with a helper error. Question is how to be able to :render :partial = from the views folder in my plugin

• Manual stack backtrace on Windows mobile (SEH)

  - by caahab

  Following situation: I'm developing an windows mobile application using the sdk 6. Target machine is a nautiz x7. To improve the error reporting I want to catch the structured exceptions (SEH) and do a stack backtrace to store some information for analysis. So far I have the information where the exception was thrown (windows core.dll) and I can backtrace the return adresses thru the stack. But what I want to know is, which instruction in my code caused the exception? Does anyone know how to use the available exception and context information to get the appropriate function/instruction address? Unfortunately windows mobile 6 sdk for pocketpc does not support all the helper functions to do stackwalks or mini dumps.

• ASP.Net MVC null reference exception with TextArea name

  - by kingrichard2005

  Hello, I have a TextArea html helper method I'm calling in a foreach loop. Basically, when I initially load the View it works fine, but when i reload the View and load postback data, the same TextArea throws a NullReferencException and yet the variable I'm using in the TextArea as the name of the TextArea is not null. I've attached a picture below for demonstration: Sorry if it's difficult to see, the blue arrow below is pointing to the variable used to name the TextArea. Again, it works on initial load, but it errors out on postback when the page is reloaded. I'm not sure what's going on.

• Is Dynamic Casting Possible in Java

  - by Tom Tucker

  So I have a class of overloaded methods like this: class Foo { public void test(Object value) { ... } public void test(String value) { ... } } I need to pass a property value of a bean to one of these methods depending on its type, but I don't know the actual property type until the runtime. e.g. public void run(Object bean, String propertyName) { Foo foo = new Foo(); foo.test(PropertyUtils.getProperty(bean, propertyName)); } BTW, PropertyUtils.getProperty() is a helper method that returns a value of the specified property on a bean. PropertyUtils.getProperty() returns an Object, so that test(Object value) will be always called and the actual property type will be ignored. I can figure out the propery type in the runtime, even if its value is null. Is there such a thing as dynamic casting in Java? If not, is there a way to have an overloaded method with the correct parameter type called?

• Exposing classes inside modules within a Python package directly in the package's namespace

  - by Richard Waite

  I have a wxPython application with the various GUI classes in their own modules in a package called gui. With this setup, importing the main window would be done as follows: from gui.mainwindow import MainWindow This looked messy to me so I changed the __init__.py file for the gui package to import the class directly into the package namespace: from mainwindow import MainWindow This allows me to import the main window like this: from gui import MainWindow This looks better to me aesthetically and I think it also more closely represents what I'm doing (importing the MainWindow class from the gui "namespace"). The reason I made the gui package was to keep all the GUI stuff together. I could have just as easily made a single gui module and stuffed all the GUI classes in it, but I think that would have been unmanageable. The package now appears to work like a module, but allows me to separate the classes into their own modules (along with helper functions, etc.). This whole thing strikes me as somewhat petty, I just thought I'd throw it out there to see what others think about the idea.

• I need to debug my BrowserHelperObject (BHO) (in C++ with Visual Studio 2008) after a internet explo

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• How should important terms be emphasized in documentation?

  - by John Rasch

  Software will often introduce and formalize concepts that may have ambiguous definitions in the real world. For example, in an attendance tracking system, an Occurrence refers to an Excused Absence, an Unexcused Absence, or a Tardy. In technical documentation (both in helper text and in user guides, etc), should these concepts be proper nouns, and as such, should they be capitalized in usage? In other words, which of the following examples is more appropriate: After an Occurrence has been created, it may be converted into an Excused Absence once the Approval Form has been uploaded. or After an occurrence has been created, it may be converted into an excused absence once the approval form has been uploaded.

• Adding global blank option to DroDownList in MVC

  - by Diegos Grace

  Is there a way of using a templated helper in mvc so that each and every select list in my project has a custom default 'Choose an option' with null value etc. The posts I have seen seem a little complex, is it possible to have a DropDownList.ascx file in shared view folder with something like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<SelectListItem>>" %> <%= Html.DropDownList(selectlist name, selectlist value, "Choose an option")%> And then having a UIHint("DropDownList") for each dropdownlist in the ViewModel? Some guidance on syntax of parameters would be much appreciated, where name and value of the viewmodel dropdownlist plus the 'Choose an option' string are passed. Or is this all wishful thinking?

• What's a better way to display a handle for resizing a view on iPhone / iPad?

  - by Christian

  I want to display a handle at the corners of a UIView that can be used to resize the view. How can I display the handles floating on the top of everything else and still have a connection to and be in sync with a view? The solution I implemented before looks like this: I put the view into another view that shows the handles on top of the corners. The problem with this approach is that the handles add extra space to the original view's size. Since Apple recommends at least 40 x 40 px for the size of a button, it is not very little space and also goes beyond the visible bounds of the original view. Another problem is that the original view has to be encapsulated in this 'helper view' object and thus becomes a part of something although it really is the main component.
