• Wordpress page linking

  - by danixd

  I am trying to implement WordPress into quite a large site with a complex page structure and struggling to get normal pages to work (not created through the admin) The pages are created, but when I link to them, nothing happens... The desired url - www.website.com/dir1/dir2/dir3/page.php The actual url- www.website.com/wp-content/themes/themename/dir1/dir2/dir3/page.php The problem with linking to the latter is that it breaks the WordPress functions I don't want to have to give every page a template, then add it through the admin, it is too much work. I only need 2 pages to contain dynamic content. Am I being silly? I am really confused.

• CakePHP hasOne ineffeciency?

  - by Andre

  I was looking at examples on the CakePHP website, in particular hasOne used in linking models. http://book.cakephp.org/view/78/Associations-Linking-Models-Together My question is this, is CakePHP using two queries to build the array structure of data returned in a model that uses hasOne linkage? Taken from CakePHP: //Sample results from a $this-User-find() call. Array ( [User] => Array ( [id] => 121 [name] => Gwoo the Kungwoo [created] => 2007-05-01 10:31:01 ) [Profile] => Array ( [id] => 12 [user_id] => 121 [skill] => Baking Cakes [created] => 2007-05-01 10:31:01 ) ) Hope this all makes sense.

• Import C + Makefile into a linux IDE?

  - by Jessica

  I have a project for Linux that i've been developing for some time. Basically it's a bunch of C and H files together with a directory structure and a Makefile. Every time I need to debug something it's so painful, I need to manually search for var. definitions, structs, etc. Is there any good IDE out there for Linux that will allow me to import those files into a "project" and that will provide code completion or at least an easy way to get my bearings in the source code? thanks!

• Flexible Data source for Multi-Section Table View Controller

  - by TuanCM

  I have a TableViewController which display a list of NewsItem objects: @interface NewsItem : NSObject { NSString *feedID; NSString *title; NSDate *published; } I'm trying to implement a Table View Controller (multiple sections) that can display the list in two ways: One divide News Items into sections which based on Published Date The other would be based on FeedID (News source). And I don't know how to structure the data source so that the code is easy to maintain. I tried to put the list of News Items into a 2 dimension Array in this case is a NSMutableArray of NSArray objects. However I got some objc_exception_throw and I don't think this is flexible enough. Could you guys give me some ideas?

• Enumerating all hamiltonian paths from start to end vertex in grid graph

  - by Eric

  Hello, I'm trying to count the number of Hamiltonian paths from a specified start vertex that end at another specified vertex in a grid graph. Right now I have a solution that uses backtracking recursion but is incredibly slow in practice (e.g. O(n!) / 3 hours for 7x7). I've tried a couple of speedup techniques such as maintaining a list of reachable nodes, making sure the end node is still reachable, and checking for isolated nodes, but all of these slowed my solution down. I know that the problem is NP-complete, but it seems like some reasonable speedups should be achievable in the grid structure. Since I'm trying to count all the paths, I'm sure that the search must be exhaustive, but I'm having trouble figuring out how to prune out paths that aren't promising. Does anyone have some suggestions for speeding the search up? Or an alternate search algorithm?

• Big-O for Eight Year Olds?

  - by Jason Baker

  I'm asking more about what this means to my code. I understand the concepts mathematically, I just have a hard time wrapping my head around what they mean conceptually. For example, if one were to perform an O(1) operation on a data structure, I understand that the amount of operations it has to perform won't grow because there are more items. And an O(n) operation would mean that you would perform a set of operations on each element. Could somebody fill in the blanks here? Like what exactly would an O(n^2) operation do? And what the heck does it mean if an operation is O(n log(n))? And does somebody have to smoke crack to write an O(x!)?

• How can I use Linq to create an array of dictionaries from XML?

  - by Duke

  Given the following XML structure: <courses> <course> <title>foo</title> <description>bar</description> </course> ... </courses> How could I create an array of dictionaries such that each dictionary contains all the element/value pairs within a course? What I have right now generates an array whose elements contain a single key/value dictionary for each element/value pair in a course: XElement x = XElement.Parse("...xml string..."); var foo = (from n in x.Elements() select n) .Elements().ToDictionary(y => y.Name, y => y.Value); Produces: [0] => {[course, foo]} [1] => {[description, bar]} What I'd like is this: [0] => {[course, foo], [description, bar]}

• get the installed path of a vb.net application

  - by Matt Facer

  Hi guys... I'm nearly ready to distribute my vb.net application. I have several picturebox files which are loaded currently from c:/temp I need to change this directory to one that will be OK to use when the user installs it to their PC. My question is how can I do this? Is there a way to get the installation path, then use that within the code as a variable? eg: myInstalledPath & "/xxx.jpg" Or... would it be better for me to use mypictures within the mydocuments structure? I'd rather keep all the image files created in a folder which is more hidden from the user (by hidden I mean not cluttering up their own image folders!) I've tried searching for this, but I seem to get varying results with no real answers... (possibly searching for the wrong thing!)

• How to hash and check for equality of objects with circular references

  - by mfya

  I have a cyclic graph-like structure that is represented by Node objects. A Node is either a scalar value (leaf) or a list of n=1 Nodes (inner node). Because of the possible circular references, I cannot simply use a recursive HashCode() function, that combines the HashCode() of all child nodes: It would end up in an infinite recursion. While the HashCode() part seems at least to be doable by flagging and ignoring already visited nodes, I'm having some troubles to think of a working and efficient algorithm for Equals(). To my surprise I did not find any useful information about this, but I'm sure many smart people have thought about good ways to solve these problems...right? Example (python): A = [ 1, 2, None ]; A[2] = A B = [ 1, 2, None ]; B[2] = B A is equal to B, because it represents exactly the same graph. BTW. This question is not targeted to any specific language, but implementing hashCode() and equals() for the described Node object in Java would be a good practical example.

• Looping differences in Ruby using Range vs. Times

  - by jbjuly

  I'm trying to solve a Project Euler problem using Ruby, I used 4 different looping methods, the for-loop, times, range and upto method, however the for-loop and times method only produces the expected answer, while the range and upto method does not. I'm assuming that they are somewhat the same, but I found out it's not. Can someone please explain the differences between these methods? Here's the looping structure I used # for-loop method for n in 0..1 puts n end 0 1 => 0..1 # times method 2.times do |n| puts n end 0 1 => 2 # range method (0..1).each do |n| puts n end 0 1 => 0..1 # upto method 0.upto(1) do |n| puts n end 0 1 => 0

• Opinions sought on the best way to organise classes in PHP

  - by jax

  I am pretty much set on using the Java package naming convention of com.website.app.whatever but am unsure about the best way of doing this in PHP. Option 1: Create a directory structure com/ mysite/ myapp/ encryption/ PublicKeyGenerator.class.php Cipher.class.php Xml/ XmlHelper.class.php XmlResponse.class.php Now this is how Java does it, it uses the folders to organize the heirarchy. This is however a little clumsy in PHP because there is no native support for it and when you move things around you break all includes. Option 2 Name classes using a periods for the package, therefore sames are just like in Java but can all be in the same directory making __autoload a breeze. classes/ com.mysite.myapp.encription.PublicKeyGenerator.class.php com.mysite.myapp.encription.Cipher.class.php com.mysite.myapp.xml.XmlHelper.class.php com.mysite.myapp.xml.XmlResponse.class.php The only real disadvantage here is that all the classes are in a single folder which might be confusing for large projects. Opinions sought, which is the best or are there other even better options?

• Open page in Joomla

  - by dutt

  I'm using Jumi to echo php code and then showing that in a Joomla Article, and everythings working fine. Now I want to do this: The output is basically a list from a database like this: Name Price Type A 1 T1 B 2 T2 In this list I want to include links to only show items of the same type, so "T1" would like to a page only showing things of type T1. So I thought I would do this by making a new page that takes a type and then get all the items of that type from the database. Without Joomla this wouldv'e been a piece of cake, with Joomla I'm not quite sure where to begin. How should the a href=... tags in the html code printed by my php script look? Is my basic structure still correct, and if so, how do I make Joomla open the new page in the normal frame and not replace the whole Joomla page. some kind of target-frame attribute?

• Using stored procedures to generate RDLC report in C#

  - by NDraskovic

  I'm making an application that generates reports for my client. I'm using his database that contains stored procedures which return the data needed for the reports. The problem is that I don't know how to execute them from the application (more specific the TableAdapter in my dataset). When I use the visual aid to create the TableAdapter, it shows the error "Invalid object named #table1". This is weird because there is a temporary table called #table1 in the stored procedure. When I try to do the whole job programmatically, I get the exception Incorrect syntax near '.'. An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. I created a DataTable that has identical structure as the result of the stored procedure, but I still get the same exception

• c++ Initializing a struct with an array as a member

  - by Drew Shafer

  I've got the following reduced testcase: typedef struct TestStruct { int length; int values[]; }; TestStruct t = {3, {0, 1, 2}}; This works with Visual C++, but doesn't compile with g++ under linux. Can anyone help me make this specific kind of initializer portable? Additional details: the actual structure I'm working with has several other int values, and the array can range in length from a single entry to over 1800 entries. Any help much appreciated. Thanks!

• Write to a binary file?

  - by rick irby

  Here is data structure w/ variables: struct Part_record { char id_no[3]; int qoh; string desc; double price: }; --- (Using "cin" to input data) --- Part_record null_part = {" ", 0," ",0.0}; --- --- file.seekg( -(long)sizeof(Part_record), ios::cur); file.write( ( char *)&part, sizeof(Part_record) ); The three variables, qoh, Id_no & price, write out correctly, but the "desc" variable is not right. Do I need to initialize Part_record some other way? It should be 20 characters in length. If you have enough info here, pls share your advice,thanks.

• Get records based on child condition

  - by Shawn Mclean

  In LINQ To Entities: How do I get the records (including both child and parent) based on a condition of the child in a one to many. My structure is set up as follows: GetResources() - returns a list of Resources. GetResources().ResourceNames - this is the child, which is an entity collection. GetResources().ResourceNames - a property of one record of this child is Name. I'd like to construct something like this: return (from p in repository.GetResources() where p.ResourceNames.Exist(r => r.Name.Contains(text, StringComparison.CurrentCultureIgnoreCase)) select p).ToList(); but of course, Exist doesn't exist. thanks.

• Check if XML node is empty

  - by Vinit

  I have a simple XML structure like <main> <node1><!-- comments --><!-- comments --></node1> </main> and this can have any number of sub-nodes or values like: <main> <node1><!-- comments --><!-- comments --><p>texttext text</p> more text <br/></node1> </main> I want to check if the node is empty or not: I'm doing something like: <xsl:if test="string-length(main/node1//text())&gt;0"> But it does not work as if there are multiple tags, then string-length function will break coz of multiple arguments. Any help to solve this issue is really appreciated.

• How do I dynamically define an instance variable?

  - by Moses

  Hi everyone, I have two classes (class1 and class2) that just store data, no methods. I have a third class that has an instance variable that, depending on some user input, will be set to one of the two classes. So, in the third class I declare the variable generically as NSObject *aClass; and during runtime set it to whatever it should be. aClass = [[Class1 alloc] init]; // or aClass = [[Class2 alloc] init]; However, when I try to access fields from aClass NSString *str = aClass.field1; It gives me the error: request for member 'field1' in something not a structure or a union. Field1 is declared in both class1 and class2. When I try to cast aClass aClass = (Class1 *) aClass; it gives the same error. What am I doing wrong, is there a better way to do this?

• Removing items from lists and all references to them.

  - by LiamV

  I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node?

• jquery toggle+paginate+multiple instances

  - by mark

  Hi, I'm a jquery newbie - wanted to ask what might be the best strategy for achieving what I am after as I think it uses a mix of jquery functions : If list of items exceeds 5 items a 'more' link appears which when toggled will reveal the rest of the items. If items list is 5 or less no 'more' link is shown. Hide button also at bottom of long full revealed list. (perhaps this is toggle+pagination?) And then also that this can be used in multiple instances, as it is for multiple category menu's.(to be used in typical indexhibit websites structure like http://mikeyburton.com/) link 1 link 2 link 3 link 4 link 5 link 6 link 7 link 8 more Any help or links greatly appreciated.

Any ideas?

• OutputPath ignored on projects being build by TFS 2010

  - by bovium

  I have installed TFS2010 Beta 2 with default settings and configured a CI build with a solution containing the indivial projects. My *.cspoj files could have: <OutputPath>bin\debug\</OutputPath> Or alternatively: <OutDir>bin\debug\</OutDir> When the build server is done building and running tests etc. all the assemblies are placed in the root of the build drop off folder. How do I configure the build to keep the outputpath or outdir in my projects and store the assemblies and content in the matching folder structure( builddropfolder\bin\debug\ )? I have found a number of post on this most of them relates to TFS 2008 but I have not found solutions for TFS 2010. Perhaps it is possible to solve this in the new workflow file for the buildserver?

  I have my html set up like this: <li> Header <button>Edit</button> </li> And I was wondering if there is a way so that you can click on the li and have one action happen and click on the button and have another action happen. Right now if I have a jquery click element on the li it gets fired when you hit the button to. Is there a way to make this separate without changing the html structure?
