  • Drupal, Lightbox: cannot edit the content inside

    - by Patrick
    hi, I'm using Drupal and Lightbox module to display the content of articles in this website: donatellabernardi.ch/drupal if you click on an article the lightbox is displayed. However I have 2 problems with it: 1) I cannot use the libraries such as the tooltip library qTip from it. (If you move the mouse over the balls, you'll see the tooltips) 2) I cannot invert the title with the balls (tags), because it seems that the template of the node in the lightbox is not controlled by my theme. I tried also to change the node template (in the drupal root folder), swapping title and meta data but it didn't work. thanks

  • How do you share pre-calculated data between calls to a Rails web service?

    - by Nigel Thorne
    I have a Rails app that allows users to build up a network structure and then ask questions about how to navigate around it. When adding nodes and connections these are just saved to the database. At the point you make a query of the network I calculate the shortest path from any node to any other node. Constructing this in memory takes a while (something I need to fix), but once it is there, you can instantly get the answer to any of these path questions. The question is... How do I share this network between calls to the website, so each request doesn't regenerate the paths network each time? Note: I am hosting this on apache server using passenger (mod ruby) Thoughts?

  • How to get an ordered list parsed by XML parser?

    - by Matthias Doringer
    I am using a xsd schema file; there I specified an ordered list. When parsing an XML node of the kind... <myOrderedList> "element_1" "element_2" "element_3" </myOrderedList> (which is valid XML syntax) ...all XML parsers I know parse this as a single node element. Is there a way to get the XML parser parse this list for me (return it as a list or an array or whatever) or do I always have to parse it myself?

  • Drupal CCK Text field not saving.

    - by Mark Milbourne
    Hey Guys, I've been trying to write a CCK Field based on the Text field. But if I create a standard CCK Text field with only 1 value. Then edit a content item for this type, the values are never persisted. When I go back in and edit the same node, the value isn't there. I checked the database and its not in the table for the CCK node. If I use more than one value it works fine. I'm upto date on CCK (6.x-2.6) and CTools (6.x-1.5). Has anyone seen this? and a possible solution?

  • Problem with JPopupMenu in a JTree

    - by Alex
    Hi guys I have this issue. In a custom JTree I implemented a JPopupMenu to display different JMenuItem according to the node selected using a MouseListener. The JPopupMenu is shown when the mouse right button is clicked. The problem is that if I don’t choose an Item from the PopupMenu but instead I select another node in the tree, either with right or left buttons, this event is never caught by the tree MouseListener Could anyone point me in the right direction to solve this? In case an example is available I’ll appreciate it. Thanks.

  • Is shortening properties names worth it?

    - by raam86
    in how to node Blog rolling with node.js and mongoDB the author mentions it's a good idea to shorten proprieties names: ....oft-reported issue with mongoDB is the size of the data on the disk... each and every record stores all the field-names .... This means that it can often be more space-efficient to have properties such as 't', or 'b' rather than 'title' or 'body', however for fear of confusion I would avoid this unless truly required! I am aware of solutions of how to do it I am more intrested in when is it truly required?

  • how to implement this observer pattern?

    - by lethal
    Hello. I have 4 classes, that describe state diagram. Node, Edge, ComponentOfNode, ComponentOfEdge. ComponentOfEdge compounds from ComponentsOfNode. Node can have 0..n outgoing edges. Edge can have only 2 nodes. Edge should be able to offer ComponentOfNode, but only from nodes that Edge has, in form ComponentOfEdge. The user can change ComponentsOfNode. I need this change spreads to all Edge. Hw to do it? I expect the observer should be used. Can you give me example in pseudocode please?

I need to call all the classA, classB, classC from classABC. #import <Foundation/Foundation.h> #import "cocos2d.h" @interface classABC : CCLayer { classA *aClass; } @property(nonatomic, retain)classA *aClass; @end #import "classABC" #import "classA.h" #import "classB.h" #import "classC.h" @implementation classABC -(id)init { if( (self = [super init]) ) { ClassA *aClass = [[ClassA alloc]init]; CCScene *aClassS = [CCScene node]; CCLayer * aClassL = [aClass node]; [aClassS addChild: aClassL]; [[CCDirector sharedDirector] setAnimationInterval:60.0/60]; [[CCDirector sharedDirector] replaceScene: aClass]; } return self; } @end But I am not getting the classA displayed. How should I do it ? Thank You.

  • Better to extend a class or modify it directly?

    - by primehunter326
    Hi, So I'm working on creating a visualization for a data structure in Java. I already have the implementation of the data structure (Binary Search Tree) to start with, but I need to add some additional functionality to the included node class. As far as conventions and best practices are concerned, should I create a subclass of the node with this added functionality or should I just modify what I have and document it there? My question is similar to what's asked here but that's a little over my head. I know it probably doesn't matter much for what I'm doing, so I'm asking this more as a general thing.

  • How do i change the address of a New struct in a loop?!

    - by Yasin
    Hi guys, i'm writing a simple code which is about polynomials using link lists in C#. the problem i have is that whenever it creates a new struct (node) in the for loop it gives it the same address as the previous node was given. so how do i fix it ? here is my struct : struct poly { public int coef; public int pow; public poly* link;} ; and here is the where the problem occurs: for (; i < this.textBox1.Text.Length; i++) { q = new poly(); ...... p->link = &q; } &q remains unchanged !

  • XPath to compare two distinct attributes of two elements

    - by user364902
    Suppose I have this XML: <x> <e s="1" t="A"/> <e s="2" t="A"/> <e s="1" t="B"/> </x> Is there any way to write an xpath to find any nodes named "e" which have the same value of @s as another node but a different value of @t for the same node. The first part is easy: //e[@s = //e/@s] as is the second part: //e[@t != //e[@t]] But I don't see any way to construct an xpath that compares two different attributes for two separate elements "e". Is there a way within the xpath syntax, or is it hopeless?

  • Is it possible to add two nodes at a time dynamically to a treeview

    - by Dorababu
    I am having a tree-view on my main form with initially some nodes as follows ACH |-> some.txt |->FileHeader |->BatchHeader Now at this point i will have to add 2 child nodes at a time to BatchHeader. This nodes i will pass as strings from child forms My sample code that i added some nodes is as follows public void loadingDatafrom(string filename, bool str) { if (Append.oldbatchcontrol != filename) { if (tvwACH.SelectedNode.Text == "FileHeader") { tvwACH.SelectedNode.Nodes.Add(filename); } if (tvwACH.SelectedNode.Text == "BatchHeader" && filecontrolvariables.m_gridclick == false) { tvwACH.SelectedNode.Nodes.Add(filename); **I got this idea tvwach.SelectedNode.Lastnode.Nodes.Add("Node");** } } } Can any one give an idea to add 2 nodes as child to the existing node ..

  • executorservice to read data from database in chuncks and run process on them

    - by TazMan
    I'm trying to write a process that would read data from a database and upload it onto a cloud datastore. How can I decide the partition strategy of the data? I want to query the table in chunks and process each chunk in 10 threads. Each thread basically will send the data to an individual node on a 10 node cluster on the cloud.. Where in the below multi threading code will the dataquery to extract and send 10 concurrent requests for uploading data to cloud would be? public class Caller { public static void main(String[] args) { ExecutorService executor = Executors.newFixedThreadPool(10); for (int i = 0; i < 10; i++) { Runnable worker = new DomainCDCProcessor(i); executor.execute(worker); } executor.shutdown(); while (!executor.isTerminated()) { } System.out.println("Finished all threads"); } }

  • Is dynamic evaluation of xpath variable string possible using .net 2.0 xslt implementation?

    - by Crocked
    Hi, I'm trying to evaluate an xpath varable I'm building dynamically based on the position of the node. I can create the xpath string in a variable but when I select the value of this just get the string and not the node set I need. I use the following to create the xpath <xsl:variable name="xpathstring" select="normalize-space(concat(&quot;//anAttribute[@key='pos&quot;,position(),&quot;']&quot;))"/> and try to output the value with the following. <xsl:value-of select="$xpathstring"/> If I execute the xpath in my debugger I get the nodeset but in my xml output only get the xpath string which looks like this //anAttribute[@key='pos1'] I had a look at exslt dyn:evaluate which seems to enable this but this seems to be only supported by certain processors and doesn't provide a standalone implementation or at least as far as I could see (currently using the standard .net 2.0 xslt whihc is only xslt 1.0 as far as I recall) Is there anyway to handle this without changing processor? Kind Regards, Crocked

What's the xpath to do that? I'm using .net 4 and xpath 1.0

  • Creating a new CCK field from an imagecache preset?

    - by oalo
    I have an image gallery for which I have configured an Imagecache preset. It's my first time using Imagecache so I am not sure if I am using it right. Right now, I see that I can only configure the CCK imagefield to show me the imagecache generated image in either the preview or the full node version of the field. I would prefer to have a new CCK field with the imagecache generated picture. Is this possible? Is there a module for this? If it isnt, how can I customize my gallery view to show me the preview version of the image, instead of the full node version, which it is currently showing?

  • How to calculate the state of a graph?

    - by zcb
    Given a graph G=(V,E), each node i is associated with 'Ci' number of objects. At each step, for every node i, the Ci objects will be taken away by the neighbors of i equally. After K steps, output the number of objects of the top five nodes which has the most objects. Some Constrains: |V|<10^5, |E|<2*10^5, K<10^7, Ci<1000 My current idea is: represent the transformation in each step with a matrix. This problem is converted to the calculation of the power of matrix. But this solution is much too slow considering |V| can be 10^5. Is there any faster way to do it?

  • What's the best way to move "a child up" in a .NET XmlDocument?

    - by Mike
    Given an XML structure like this: <garage> <car>Firebird</car> <car>Altima</car> <car>Prius</car> </garage> I want to "move" the Prius node "one level up" so it appears above the Altima node. Here's the final structure I want: <garage> <car>Firebird</car> <car>Prius</car> <car>Altima</car> </garage> So given the C# code: XmlNode priusNode = GetReferenceToPriusNode() What's the best way to cause the priusNode to "move up" one place in the garage's child list?
